XBD SERIES SINGLE-STAGE SINGLE-SUCTION FIRE-FIGHTING PUMP

Diameter of pump

Single-stage single-suction vertical pump

Single-stage single-suction horizontai pump (L/S)Rated flow

(MPa)1010 times that of rated pressure Motor as the prime mover

Code of fire-fighting pump

a.

b.

c.HT250QT400-18 The pump is a single-stage single-suction centrifugal pump, vertically or horizontally mounte

d.

It can be mounted with multiple ways upon the conditions of use on the spot and can be in series or in parallel according to the flow or pressure requirement to get the desired flow or pre-ssure.

It uses a low-noise sealed bearing, which is in ject ed w-ith greas ewhen ex-works and can run in successive two years, its unit has a high concentricity and impeller has a very good dy-nam ic balance and low vibration during running, improving the environment of use.

Its shaft seal is a mechanical one ,settlin g the serious leak of the stuffing of common centrifugal pumps, enlarging the dur-ation and making sure of a chean and neat spot.

Materials of the pump

a.Pump shaft stainless steel

b.Impeller cast copper

c.Under-pressure parts cast iron Ht250 or QT400-18

Those parts which may produce friction when the pump is rotating are made of the combined material of wearable, anticorrosive and high joining-up noise and avoid rust-water forming to prevent the spraying fire-fighting parts from bein g block ed, greatly extending the duration and getting rid of the phenomenon to be gripped by rusting and no way to be used ag-ain after stop.
