磁力泵操作规程

磁力泵操作规程1.磁力泵的运行1.1试车前的准备工作管道必须进行吹扫、清洗、为防止残留的杂质、焊渣进入泵腔,在泵进口处须配有过滤器或过滤网.检查名部分螺栓、连接件是否有松动,有松动的要加以坚固.用手盘动联轴节,使泵转子转动几圈,看转动是否灵活,是否有响声或轻重不匀的感觉,以判断泵内有无异物.1.2启动程序打开吸入阀<进口阀>,关闭排出阀〔出口阀〕、压力表阀、真空表阀,进行灌泵.稍开排出阀,点动电动机,查看电机转向.转向正确后,启动电动机,找开压力表、真空表阀.在压力上升并认为机器运转开稳后,徐徐打开排出阀,泵进行正常工作〔离心泵排出阀微开启动,是为了轻载起步,减小点动电流,但必须注意:旋涡泵必须开阀启动〕.泵运行点应在工况点上下浮动,过小、过大流量均易造成泵损坏.绝不允许用吸入管路上的阀门来调节流量,以免产生气蚀.2.磁力泵的停车2.1缓慢关闭排出阀.2.2停止电机.2.3关闭泵进口阀门.2.4如环境温度低于液体凝固点时,要放净泵内液体,以防冻裂.2.5长时间停止使用的泵,除将泵内的腐蚀性液体放净外,还要用清水冲洗干净,尤其是密封室认真冲洗干净.最好是将泵拆下清洗后重新装好,并将泵的进出口封闭后妥善保管.2.6禁止在出口阀门未关闭的情况下停车,以免出口管路液体倒流使叶轮反转,损坏零件.3.磁力泵操作中注意事项3.1泵决不允许空载运行,如果不能保证,须安装空载保护装置,压力传感器或负载测控器.一旦断液或泵内有摩擦,则保护装置响应后跳闸,防止泵空载而造成进一步的损坏.3.2如果磁力泵配备的电机超过7.5KW,最好能配备慢启动装置〔如星三角启动器〕.因为电机启动时,启动扭矩大,而配备的磁钢扭矩如果小于起动扭矩时,则内外磁钢会出现滑脱现象,即外转子转动而内转子不动,导致涡流热不能与时排出,引起温度极度升高,而最终使得内外联轴器退磁,无法运行.3.3如果泵内有易凝固的介质,则开车前须先通蒸气,等介质充分溶化后,方可开车运行.3.4在离心泵试运转中,要检查整个系统有无漏气、漏液,性能是否符合要求,机组有否较大的振动和不正常的响声,在各方面都认为合格后,方可投入运转.4.磁力驱动泵维护和保养磁力泵必须作好日常的维护和保养工作,才能有效地发挥泵良好性能,延长泵的使用寿命.4.1运行中上监视和维护:泵在运行中,要加强对机组的巡视工作,与早发现异常,尽快作出处理.在巡视中,一般要随时留意下列几个方面:注意机组的响声和振动情况是否正常.观察电流表、电压表、压力表、真空表和流量计等仪表读数是否正常.注意管路是否有漏气、漏液等.平时保持机组的清洁,并注意操作安全.4.2运行后的保养在寒冷的季节,尤其在室外的泵,在停车后应立即去掉泵内液体,以防结冰冻.一般的备用泵,也应定时启动一次.泵要定时检修,检查并更换不合格的易损件,如轴承、轴套、止推环等.轴承箱中的润滑脂要定期添加.5.泵运行中的常见故障与其排除方法磁力泵在运行中出现的常见故障,可分为两类:一类是泵输液工作性能变坏,如流量减小,扬程降低,发生气蚀等.这类故障称性能故障〔亦叫水力故障〕;另一类故障是机械上的问题,如轴承烧坏,轴弯曲,叶轮断裂等,系机械故障.造成故障的原因很多,可能是选型与安装不正确,或者是操作维护不得法,又或者是原动机的问题等等.现将常见的故障现象和可能引起的原因,以与排除方法,列于下表.故障与防治磁力泵操作注意事项1、泵在调试时,假如单一试电机,可以拆掉中间连轴节,重新安装时必须对中.如果不拆电机调试磁力泵,必须保证泵腔充满液体,在泵没有空载的情况下进行,可以先点动电动机,看转向,当转向正确后,正式启动泵.2、第一次开车时,管路里会有空气,可在管路上装上排气孔.在开车前先排气,再启动磁力泵.3、磁力泵启动前,先盘动磁力泵外联轴器,当盘动外联轴器轻松灵活无杂声时,则开始启动泵.并且,还应在进口阀门全开,出口阀门微开或关闭时进行.当电机正常运转时再慢慢开启出口阀.4、磁力泵使用必须在样本中所规定流量、扬程点的X围内使用〔一般在额定的40%—120%之间运行〕.5、泵运行后调整出口阀,调至所需流量或规定流量,运行时应检查压力、流量、振动、噪音.如果液体有汽化现象〔表现为压力表指针晃动或泵进口处有杂音〕需减小出口阀门开度,减少流量来排除故障.6、泵停车时为了防止液体倒流引起倒转,应先关出口阀,再停电机,进口阀门可以不关闭7、当温度降至冰冻时,泵壳里可能有一些水冰住了叶轮,而泵转不动,在这种情况下,请先把冰溶了再开车.8、磁力泵严禁空载运转,每台磁力泵必须配置欠流保护器,当空载或过载时,保护器响应自动切断电源而停车.已经配置保护器的,按照要求对保护器予以设定.操作工应对上述应知应会,严禁违规操作.磁力泵操作规程启动前的准备工作 a 清理设备周围影响设备和操作人员安全的杂物. b 检查密封水槽内的工艺水是否在正常工作液位,不足时应补加. c 检查密封水管道上所有阀门要开关正确. d 在长期停机或泵检修后第一次开车时,拆下电机的风扇罩并手动盘车,检查磁力泵转动是否灵活,在确认没有问题后装好风扇罩. e 打开泵的进口阀,关闭泵的出口阀. f 通知电工向现场操作盘送电.启动 a 启动泵,检查泵的声音与振动情况. b在确认没有异常的情况下打开泵的出口阀.正常停车关闭出口阀,然后立即停止电动机,随后再关闭进口阀.紧急停车立即停止电动机,然后再关闭出口阀和进口阀.运行中注意事项 a 注意吸入端过滤器的前后压力差,压力差增加时,表示过滤器上有异物堵塞,要停止泵运行,以便清洗粗滤器. b 排出量、排出压力是否符合规定值; c 有无异常声音与振动,若发生异常声音或振动,一般情况说明有气蚀或轴承过度磨损. e 泵是否发生气蚀:打开泵的出口阀门,当流量达到一定量,突然发出响声和振动,这时继续开大阀门,如果流量仍不增加,说明有气蚀.有气蚀时要进行排气操作.注意:磁力泵在气蚀状态下绝对不能运转,如果在这种状态下继续运转,则会引起轴承早期磨损. f电动机的电流值是否超过额定电流. g 泵各部位的温度有无异常过热的状况. h 氮气稳压系统的压力应保持在规定的X围内1.一定要注意灌泵充分,因为磁力泵的轴承大部分是非金属材料的.2.磁力泵操作温度要注意,不能超温,否则会造成磁力转子脱磁,效率下降,扬程达不到设计要求,甚至完全失效,要更换磁力套.。

磁力泵操作规程

磁力泵操作规程一、启动1.01 确保管路经吹扫或者冲洗后无焊渣、铁屑、碎布及其他杂质后泵才可以进行使用。
1.02 确保吸入管路无阻塞、无漏点,阀门能正常开启。
1.03 润滑:(1)采用免维护轴承,不需要加注润滑油和润滑脂。
(2)采用稀油润滑,移去恒油杯,打开轴承箱体上部的放气塞,从顶部加注润滑油至油窗的中心部位,将恒油杯注满上。
1.04 手动盘车检查泵的转动情况。
1.05 关闭所有的排液口。
打开入口阀门和出口阀门进行灌泵,保证泵腔和转子腔内彻底灌满。
1.06 点车检查机电的转向与泵的转向(泵上箭头所指的方向)是否一致。
1.07 关闭出口阀门(稍微开启一点也可以)。
1.08 注意出口压力表的读数,然后启动机电,当机电达到正常转速后,慢慢打开出口阀门,观察出口压力表,当压力表的读数达到泵的出口压力即可(出口压力等于进口压力加之泵的扬程、介质密度换算的压力值之和)。
1.09 观察泵的运行情况,如压力是否稳定,运行声音、发热及振动是否正常。
注意:1.任何情况下泵都不允许长期反转。
2.任何情况下泵都不允许干运转。
3.泵不允许在零流量下运转,防止泵发生汽蚀,所以当机电达到正常转速后,开出口阀门。
4.泵不允许在汽蚀状态下工作,泵的汽蚀会导致泵的零部件损坏。
5.泵不允许在超过额定流量较大的情况下运行。
6.泵不允许在低于最小流量的情况下运行。
1.12 如发现泵运行异常,应即将停车检查。
1.13 进口阀门要全部打开,决不允许用进口阀门来调节流量,以防泵发生汽蚀。
1.14 如果介质在环境温度下结晶,停机后要排净泵内介质或者采取保温措施。
1.15 如果长期住手使用,应将泵内介质排除,并冲洗干净做防锈处理。
1.16 针对高温介质或者低温介质,灌泵时要注意升温或者降温速度,应缓慢打开进口阀门,按每小时温升不超过50°C 的速度进行暖泵,按每小时温降不超过30°C 的速度进行冷泵。
1.17 如果泵有保温夹套,则必须将夹套加热到工艺要求的温度,并应在泵启动之前,保证泵有足够时间使产品的温度上升到工艺要求的温度。
易威齐磁力泵资料

易威奇磁力泵同使用机械密封或填料密封的离心泵相比较,磁力泵具有以下优点。
1.泵轴由动密封变成封闭式静密封,彻底避免了介质泄漏。
2.无需独立润滑和冷却水,降低了能耗。
3.由联轴器传动变成同步拖动,不存在接触和摩擦。
功耗小、效率高,且具有阻尼减振作用,减少了电动机振动对泵的影响和泵发生气蚀振动时对电动机的影响。
4.过载时,内、外磁转子相对滑脱,对电机、泵有保护作用。
四、运行注意事项1.防止颗粒进入(1)不允许有铁磁杂质、颗粒进入磁力传动器和轴承摩擦副。
(2)输送易结晶或沉淀的介质后要及时冲洗(停泵后向泵腔内灌注清水,运转1min后排放干净),以保障滑动轴承的使用寿命。
(3)输送含有固体颗粒的介质时,应在泵流管入口处过滤。
2.防止退磁(1)磁力矩不可设计得过小。
(2)应在规定温度条件下运行,严禁介质温度超标。
可在磁力泵隔离套外表面装设铂电阻温度传感器检测环隙区域的温升,以便温度超限时报警或停机。
3.防止干摩擦(1)严禁空转。
(2)严禁介质抽空。
(3)在出口阀关闭的情况下,泵连续运转时间不得超过2min,以防磁力传动器过热而失效。
磁力泵工作原理当电动机带动外磁转子旋转时,磁场能穿透空气隙和非磁性物质,带动与叶轮相连的内磁转子作同步旋转,实现动力的无接触传递,将动密封转化为静密封。
由于泵轴、内磁转子被泵体、隔离套完全封闭,从而彻底解决了“跑、冒、滴、漏”问题,消除了炼油化工行业易燃、易爆、有毒、有害介质通过泵密封泄漏的安全隐患,有力地保证了职工的身心健康和安全生产。
一、磁力泵工作原理将n对磁体(n为偶数)按规律排列组装在磁力传动器的内、外磁转子上,使磁体部分相互组成完整藕合的磁力系统。
当内、外两磁极处于异极相对,即两个磁极间的位移角Φ=0,此时磁系统的磁能最低;当磁极转动到同极相对,即两个磁极间的位移角Φ=2π/n,此时磁系统的磁能最大。
去掉外力后,由于磁系统的磁极相互排斥,磁力将使磁体恢复到磁能最低的状态。

A magnet coupling is formed using an inner, or driven magnet, attached to the impeller and an outer, or drive magnet, attached to the motor shaft. This design eliminates mechanical shaft seals or packing, since there is no direct connection between the motor shaft and the impeller. The front and rear casings, sealed with a static o-ring, form the pump or liquid end. The magnetic field is transmitted from the drive magnet through the rear casing to the driven magnet that is attached to the impeller. The combined coupling torque of the drive magnet and impeller magnet provides the driving power to theDrive MagnetDriven Magnet4 MODELGUIDEIDENTIFICATION1 2 3 4 5 6 7 81.

Handle the pump carefullyStrong impact to the pump assembly may result in damage or reduced performance.2. StartingBefore priming the pump be sure the power is turned off then proceed with filling the pumpend with water. Note, the pump must be fully primed before starting.Next close the valve on the outlet or discharge side of pump. Turn on power to the pump,when full speed is reached gradually open the discharge vale until specified flow rate isachieved.CautionOperating the pump dry (without liquid) may cause severe damage.3. StoppingWhen stopping the pump, first close the discharge valve gradually. When it is completelyclosed, turn off the power switch so that the pump stops. Never stop the pump suddenly byquickly closing a valve (i.e., solenoid or hydraulic valves).CautionQuick valve closure may cause water hammer that can cause severe damage to thepump.4. TemperatureThe pump itself may not suffer a change in performance due to temperature fluctuation.However, the liquid may change in terms of viscosity, vapor pressure, and corrosive properties.Pay special attention to changes in liquid characteristics as a result of temperature fluctuation.Liquid temperature range: 32 – 176°F (0 – 80°C)Ambient temperature range: 32 – 104°F (0 – 40°C)5. As there is a powerful magnet inside the pump unit, do not use any liquid that contains metallicsubstances such as iron, nickel, etc.6. Do not operate the pump in the following places:∙ Places exposed to rain and/or wind.∙ Places where the temperature falls below 32°F (0°C).∙ Places where corrosive gas (such as chlorine) is present.∙ Places exposed to splashing of water or fluid being pumped.∙ Places where the ambient temperature is 104°F (40°C) or above.∙ Places where explosive or combustible materials/gases are present.7. Do not operate the pump with the following liquids:∙ For the compatibility to chemical liquid or any special liquid, contact an Iwaki America sales representative.∙ Liquids that significantly swell polypropylene.∙ Paraffinic hydrocarbons such as gasoline and kerosene.∙ Halogenated hydrocarbons such as trichloroethylene and carbon tetrachloride.∙ Ether and low-grade ester∙ Slurry(For a chemical compatibility to guide contact Iwaki America customer service.)8. To prevent fire and explosions, do not place dangerous or flammable substances near thepump.9. Be sure unit is properly ground.10. If a pumped is damaged, it can be dangerous to operate. Contact factory for assistance.11. Avoid direct physical contact with the motor or pump during operation, as surface temperaturesmay be extremely high due to operating conditions.7 INSTALLATION, WIRING AND CONNECTIONS7.1 Installation1. Installation siteInstallation site must have an ambient temperature of 32-104°F (0-40°C) and a relativehumidity lower than 90%. Install the pump where maintenance and inspection work can bedone easily.2. Pump installation methodThis pump is not self-priming. It is recommended that the pump shall be installed in aposition lower than the liquid level of the suction tank by at least 12 inches (30 cm). If thisdistance is too short, air may enter the pump, causing damage.3. Direction of pump discharge portThe discharge port can be directed as desired. However, for efficient elimination of air inthe pump end, it is recommended that the discharge port be positioned in the horizontaldirection.4. Anchoring of baseThe base of the pump must be anchored firmly. The pump must not be mounted in avertical position.7.2 Piping instructions1. To minimize frictional resistance, the shortest piping possible with a minimum number ofbends should be utilized on the inlet or suction side of the pump.2. Use a corrosion-resistant vinyl hose that is rated at or above the pressure rating of thepump (see specification table).3. Hose size (for hose-barb style pumps)Select hose size in accordance with the diameter of the pump connections. As the hosetends to be crushed under the force, the use of a braided reinforced hose is recommended.Note, if the connection on the suction side is loose air may be mixed in with pumped fluid.(In the case of high temperature liquids, special attention must be paid to the selectionof a hose.)4. Hose connectionBe sure to cut the ends of the hose straight. Press the hose end firmly against the dischargeor suction port until it reaches the bottom of the port. Use a fastener (such as a hose clamp)to make the connection tight and leak free.CautionDo not over tighten the connection ports (suction and discharge) excessively asthey are made of plastic resin and are could be damaged.5. Valve installationInstall valves close to the suction and discharge ports.∙ Suction side valve:For easy liquid removal and pump maintenance∙ Discharge side valve:For adjustment of the discharge rate or head and for easy removal and pumpmaintenance.7.3 Wiring1. Prior to wiring the pump, confirm the voltage indicated on the nameplate is correct foryour installation. (Observe all local and national regulations regarding electrical work.)The connection diagram is presented on the next page.2. The pump does not have an external switch. It starts when power is supplied to the pumpwires.Wiring diagrams• (W)MD-15R, 20R, 20RX, 20RZ, 30R, 30RX and 30RZ (Single-phase capacitor run motor withthermal protector)• (W)MD-40R, 40RX, 40RZ, 55R, 70R, 70RZ, and 100R (Single-phase capacitor run motor withthermal protector)• MD-70R, 70RZ, and 100R models (3-phase motor, 220/380V)• (W)MD-70R, 70RZ, and 100R models (3-phase motor,400/440V)8 ASSEMBLY1. Place the motor on end vertically so that the shaft is pointed upward.2. Install the drive magnet on the motor shaft and position the shaft flush with the inside of themagnet. Note: On WMD models, screw the bracket to the motor first.3. Insert the rear casing into the magnet/motor bracket.4. Install the impeller and O-ring into the rear casing.5. Place the front casing over the pump, making sure that the volute casing is aligned.6. Using a hex head driver, fasten the liquid end to the bracket using six screws. Tighten in a starpattern.9 OPERATIONCaution• Before operating the pump, confirm that connections to the discharge and suction ports are secure.• Dry run operation (operation without liquid in the pump) damages the pump. Be sure to fill the pump with liquid prior to startup.• Do not operate the pump with closed, or almost entirely closed, suction and/or discharge side valve(s). A closed suction valve will cause dry-run operation.•Do not open or close the suction or discharge side valve suddenly, this may result indecoupling and damage to the pump end. (Under such circumstances, turn off the power supply immediately. When the motor stops rotating, the magnetic coupling will be reconnect automatically.)No. Operation StepNote1 Check piping, wiringand voltage. Check connections to confirm they are secure and leak-free. Check the power supply voltage by referring to the information on the nameplate.2Open and close valves. Fully open suction side valve. Fully close discharge side valve.3 Check that pumpchamber is filled with liquid. Fill pump chamber with priming liquid.Be sure suction line is completely filled, this is especially important if pump is above liquid level.4 Supply power topumpAfter steps 1 to 3 above, connect power supply to start pump.5 Adjust dischargecapacity & head to desired values.Adjust discharge side valve gradually till desired discharge capacity and head are obtained. Do not open or close valves suddenly.Note: Do not keep discharge side valve closed for more than 1 minute.Note: Check that pump is operating normally. If not, turn off power immediately and eliminate cause referring to 'Causes of Trouble and Troubleshooting' section (p.27).6 Checkpoints during operation Be careful to prevent solids from entering the pump. Solids in thepump may cause impeller to be locked stopping liquid circulation. The motor continues to rotate even if impeller is locked. In such acase, turn off power supply at once.Pump Stopping ProcedureStep Description No. Stopping1 Close discharge side valve. Close discharge side valve gradually.Do not use electromagnetic valve for quick closing.2 Switch power off. Check that motor stops smoothly after power supply isdisconnected. If not, pump should be inspected. (For details,contact Iwaki or your dealer.)How to store pump when it is out of use for a long timeRemove the liquid from the pump if it is to be stored for a long period of time. In addition, run it with water for about 5 minutes every 3 months to prevent rust on the motor bearing.Warning• Before draining the pump, turn off the power supply.• Be sure to wear proper safety gear (gloves, protective shoes, etc.) when handling pump end for draining purposes, especially when a hazardous chemical is being pumped.CautionNote that residual liquid may run from the discharge and suction ports when the housing isremoved. Do not allow any electric parts to come in contact with the liquid.Never discharge hazardous or chemical liquid over the ground or floor in the plant. Instead, use a draining pan (or container). Observe each applicable local law or regulation for the handling or disposal of hazardous liquids.Draining procedure1. Turn off the power supply. (Make sure no other operator will turn the power supply onaccidentally.)2. Close the discharge and suction sides valves fully.3. Remove the hoses piping attached to the pump.4. Remove the screws on the pump base to detach the pump from its mounting location.5. Rotate the pump.6. Discharge hazardous liquids appropriately.10 MAINTENANCE/INSPECTIONMaintenance and inspection• When the pump has been used for a long time, the front casing screws attaching the pump headto the motor bracket may loosen. Tighten screws periodically taking care not to deform the plastic parts. Also, after pump has been stored for a long time, tighten screws before pump is used again.• Daily inspectionCheck operating conditions (vibration, noise) as well as electric current value and pump discharge capacity. As soon as you find any abnormality, turn off power and refer to “Troubleshooting” on page 27.11 PARTS DESCRIPTION AND EXPLODED VIEWItem No. Description Item No. Description 1 Screw 5 Rear Casing 2Front Casing 6 Drive Magnet 3 O-Ring 7 Motor Assembly 8Retainer(MD-100R,100F,55F only)4Impeller9 BracketTYPICAL MD-6 through 40 TYPICAL MD-55/70/10012 DIMENSIONSDimensions in inches*Varies with motorConnectionsW H L a b c d e fNPT(M)Model HosePolypropylene Models (MD-115V models only)MD-6/10 1/2 --- 2.91 3.62 4.09 1.18 2.87 2.36 1.77 1.22 0.67WMD-15R(T) 1/2 1/2 3.50 4.26 9.46 2.37 4.15 2.50 1.94 1.52 0.85MD-15R(T) 1/2 1/2 3.74 4.39 7.05 1.97 4.59 3.35 2.17 1.52 0.85WMD-20R(T) 5/8 3/4 3.50 4.35 9.70 2.37 4.39 2.50 1.94 1.30 1.12MD-20R(T) 5/8 3/4 4.17 4.19 7.99 1.73 4.06 3.54 1.77 1.30 1.12WMD-20RX(T) 1 1 3.50 4.95 10.37 2.37 5.06 2.50 1.94 1.83 40+MD-20RX 1 1 4.17 4.75 8.66 1.73 4.45 3.54 1.74 1.83 40+WMD-20RZ 5/8 3/4 3.50 4.70 9.98 2.37 4.67 2.50 1.94 1.56 1.52MD-20RZ 5/8 3/4 4.17 4.92 8.31 1.73 4.17 3.54 2.17 1.56 1.52WMD-30R 3/4 3/4 3.50 4.70 11.65 2.37 5.72 2.50 1.94 1.89 1.22MD-30R 3/4 3/4 4.72 5.12 9.76 1.57 5.87 3.94 2.36 1.89 1.22WMD-30RX 1 1 3.50 5.09 11.89 2.37 5.96 2.50 1.94 1.97 40+MD-30RX 1 1 4.72 5.51 10.00 1.57 6.10 3.94 2.36 1.97 40+WMD-30RZ 5/8 3/4 3.50 4.70 10.97 2.37 5.04 2.50 1.94 1.56 1.53MD-30RZ 5/8 3/4 4.72 5.12 9.05 1.57 5.16 3.94 2.36 1.56 1.53WMD-40R 3/4 3/4 4.38 4.84 11.34 3.09 6.66 3.37 2.08 1.89 1.22MD-40R 3/4 3/4 4.72 5.12 9.85 1.57 5.87 3.94 2.36 1.89 1.22WMD-40RX 1 1 4.38 5.23 11.30 3.09 7.02 3.37 2.08 1.97 43+MD-40RX 1 1 4.72 5.51 10.08 1.57 6.10 3.94 2.36 1.97 43+MD-55R 1 1 4.72 6.10 10.77 1.57 7.05 3.94 2.56 2.42 1.57MD-70R 1 1 5.63 6.11 10.18 2.76 5.71 4.25 2.56 2.07 1.70MD-70RZ 3/4 3/4 5.63 6.50 9.72 2.76 5.24 4.25 2.56 1.65 1.87MD-100R 1 1 6.14 6.89 12.67 2.76 6.38 4.33 2.95 2.55 1.714.8710.432.551.713.503.00*WMD-100R 117.44*Fluoroplastic Models (MD-115V models only)(X,Y,Z) --- 1/2 3.50 5.02 11.82 2.37 6.67 2.62 2.29 1.84 1.22WMD-30FMD-30F(X,Y,Z) --- 1/2 4.72 5.12 9.09 1.57 6.77 3.94 2.36 1.53 1.52(Y,Z) --- 1 4.72 6.11 10.53 1.57 6.61 3.94 2.56 2.30 1.56MD-55FWMD-100F (Y,Z) --- 1 * 6.80 * 3.00 12.05 4.88 3.56 2.55 1.71MD-100 (Y,Z) --- 1 6.14 6.89 12.67 2.76 6.38 4.33 2.95 2.55 1.7113 TROUBLESHOOTINGPump does not start.
