PRODUCT DESCRIPTIONThese maintenance and operation instructions apply to the DESMI priming pumps B114N. The pumps have 1/2" connections on suction and pressure side. B114N is a vacuum pump of the water ring type, with mechanical shaft seal, bronze shaft, impeller and pump casing.For special applications the pump can be delivered in other material combinations – e.g. with stainless steel shaft and ductile cast iron impeller and pump casing.Max. temperature for standard design is 80°C.The pumped liquid serves as lubricant for the pumps and therefore, they do not have to be lubricated further.Max. pump speed is 3600 RPM. The pump is driven by an electric motor, which may be a standard AC motor, or a DC motor.1.1 DELIVERY- Check on receipt that the delivery is complete and undamaged.- Defects and damages, if any, to be reported to the carrier and the supplier immediatelyin order that a claim can be advanced.2. TECHNICAL DATA2.1 EXPLANATION OF THE NAME PLATEThe pumps are equipped with a name plate indicating pump type, production week, production year, item list number if the pump has been sold alone, or an order number, if the pump has been sold when built together with another machine.Before putting a pump into operation, the suitability of the material combination of the pump must always be taken into consideration. In case of doubt, contact the supplier.If the pumps are intended for special purposes the following is to be indicated:Pump No. : _________________________________________________ Pump type : _________________________________________________ Application : _________________________________________________ Comment : _________________________________________________2.2 TECHNICAL DESCRIPTIONThe noise level indicated is the airborne noise including the motor. The noise depends on the motor type supplied, as the noise from the pump can be calculated as the noise level of the motor + 2dB(A). This noise level applies to pumps with electric motors.The permissible loads on the flanges on suction and pressure side are stated in the table below:______________________________________________________________________________ DESMI Pumping Technology A/S 4Fv : The max. permissible sum of the vertical forces on the two connections. Fh : The max. permissible sum of the horizontal forces on the two connections. ∑F : The vectorial sum of the two forces Fv and Fh.∑Mt : The max. permissible sum of torques on the two connections.In connection with the permissible loads on the connections stated in the above table the following is to be observed:222⎪⎪⎭⎫⎝⎛⎪⎭⎫⎝⎛∑∑+∑∑t M calc M F calc F where index "calc" is the values calculated by the user.3. INSTALLATIONThe max. permissible loads on the connections stated in paragraph 2.2 must be observed. At installations pumping hot or very cold liquids the operator must be awarethat it is dangerous to touch the pump surface and he is to take the necessary safety measures.3.1 WIRING Wiring to be carried out by authorized skilled workmen according to the rulesand regulations in force.4. TRANSPORT/STORAGEThe pump is to be stored in a dry area.5. DISMANTLINGThe numbers in brackets refer to the position numbers on the assembly drawing.5.1 ACCESS TO IMPELLERRemove Allen screws (12) and dismantle the end cover (3). Remove the pointed screw (7). The impeller (1) can now be pulled off and inspected.5.2 SHAFT SEALRemove key (11) from the shaft (4). Remove the copper pipes (16) and (27) connected to the pump casing. Remove set screws (14) and pull the pump casing free of the shaft (4) and the electric motor and the shaft seal is pulled off the shaft. Press the seat out from behind the pump casing.5.3 INSPECTIONAfter dismantling as described in 5.1, inspect the impeller, end cover and pump casing. Replace the parts, if wear or corrosion is established in areas to such an extent that the priming ability of the pump is considerably deteriorated, or the pump makes more noise than usual. Check the seat in the shaft seal for flatness and cracks. Check rubber parts for elasticity.6. ASSEMBLING6.1 FITTING SHAFT AND SHAFT SEALFit the shaft (4) on the motor shaft. The motor shaft must entirely bottom the hole in the shaft (4). Fit and tighten the pointed screws (6) (first the middle screw). Check that the wobble of the shaft, measured as far as possible from the motor, does not exceed 0.07 mm (70 m).Fit the sealing washer (9) in the pump casing. Fit the pump casing on the motor with screws and washers (14).Please note which type of rubber is used in the shaft seal bellows. As standard the material is nitrile, but it might be EPDM which will be damaged by mineral grease. Use soft soap or silicone grease for EPDM. Before fitting the seat, clean the recess in the cover. Dip the outer rubber ring of the seat in soapy water or grease it with silicone. Now press the seat into place with the fingers and check that all parts are correctly imbedded. If it is necessary to use fitting tools, then protect the sliding surface of the seat to prevent it from being scratched or cut. Lubricate the inner diameter of the rubber bellows on the slide ring with soapy water and push it over the shaft.Push the slide ring over the shaft with the hand. If the rubber bellows is tight, use a fitting tool and take care that the slide ring is not damaged. If the carbon ring is not fixed, it is important to check that it is fitted correctly, i.e. the chamfered/lapped side is to face the seat. The carbon ring can be held by a little grease. When using soapy water on the shaft, the bellows will settle and seat in about 15 minutes and until then tightness should not be expected. After start, check by viewing the leak hole that there are no leaks.6.2 FITTING IMPELLERFit the key (11) in the shaft and lead the impeller over the shaft. Use an air gap gauge to place the impeller 0.05 mm from the pump casing when tightening the pointed screw (7). Fit the end cover and O-ring (13) with Allen screws (12). Fit the copper pipes (16) and (27) connected to the pump casing.6.3 SHAFTWhen the pump has been assembled, check that the shaft rotates freely and without noise.7. FROST PROTECTIONPumps which are not in operation during frost periods are to be drained to avoid frost damage. Alternatively, it is possible to use anti-freeze liquids in normal constructions.______________________________________________________________________________ DESMI Pumping Technology A/S 5______________________________________________________________________________ DESMI Pumping Technology A/S 68. DISMANTLINGBefore dismantling the pump make sure that it has stopped. Empty the pump of liquid before it is dismantled from the piping system. If the pump has been pumping dangerous liquids you are to be aware of this and take the necessary safety measures.If the pump has been pumping hot liquids, take great care that it is drained before it is removed from the piping system.The priming pump is designed for mounting on non-selfpriming centrifugal pumps thusmaking the pump unit self-priming. NOTE : The priming system only works if the delivery pipe on the main pump is shut off, e.g. by means of a non-return valve !9. START-UPThe pump will not function until the feed water tank has been filled with liquid. The liquid also serves as coolant for the shaft seal. In order to protect the shaftseal the pump must not run dry.The priming pump is designed for mounting on non-selfpriming centrifugal pumps thusmaking the pump unit self-priming. NOTE : The priming system only works if the delivery pipe on the main pump is shut off, e.g. by means of a non-return valve!9.1 STARTINGBefore starting the pump check that- the shaft rotates freely without jarring sounds. - the feed water tank is filled with liquid.Start the pump for a moment to check the direction of rotation. If the direction is correct (i.e. in the direction of the arrow), the pump may be started. Should the pump not function as intended, please proceed according to the fault-finding list. Bear in mind, though, that the pump was carefully checked and tested at the factory and that the majority of faults stem from the piping system.______________________________________________________________________________ DESMI Pumping Technology A/S 7______________________________________________________________________________DESMI Pumping Technology A/S 810. INSPECTION AND MAINTENANCEInspect the shaft seal in B114N for leaks at regular intervals.- Before any inspection of a pump without guard check that the unit cannot be startedunintentionally.- The system is to be without pressure and drained of liquid.- The repairman must be familiar with the type of liquid which has been pumped as wellas the safety measures he is to take when handling the liquid.11. REPAIRS11.1 ORDERING SPARE PARTSWhen ordering spare parts please always state pump type and pump No. (indicated on the name plate of the pump).
