Product Information

1、Reliable seal.This pump used a circle non-leak seal device,which consists of power and auxiliary seal and replaces the stuffing or mechanical seals with the conventional water pumps and completely settles the problems of“moving,emitting,dropping,leaking”with the conventional seals,really the idealist product replacing the conventional model WFB non-seal self-suction pump,under-liquid pump with along shaft,submersible pump,sewage-submersible pump and so on.

Shortage with model WFB pumps:

◆ Unavailable with stop water-seal ring,making liquid leak after stop,unsuitable for the frequently started case;

◆ Heavy power loss with the secondary impeller,low efficiency with the water pump;

◆ Of a conventional patter.

Advantages with model BPFZ pump:

◆ Available with stop seal,no making liquid leak after stop,suitable for the frequently started case;

◆ Optimized hydraulic and structural design,enhanced efficiency of the water pump,lowering the power of the matched motor;

◆ Of a conventional patter.

2、Use a power seal device,no wear during running,of aduration over 10 times that of the conventional ones.

3、Low cost of running with the power seal device,as 50%of the stuffing seal and 70%of the mechanical one for 10-yearrunning.

4、Stable and reliable self-suction performance,especially,with an“electric air control valve”used,truly realizing the“permanent self suction after first flow-leading”.

Product Information

Purpose

Model HW pump is a horizontal single stage single suction volute mixed flow pump and suitable for transporting pure water or the other liquid with both physical and chemical natures similar to those of water, with the temperature of the liquid to be transported not over 50℃, for the farm land irrigation, industrial and city water supply and drainage etc.multiple places. The pump's performance range: flow 130~9000m/h, head3.5~22m.

Model meaning

Take 300HW~8A as the example.
300----pump's inlet and outlet diameters. HW horizontal volute mixed flow pump.
8----designed head m.
A---cut the impeller's outer diameter or replace it with an impeller of different performance.

Mode of actuation

Direct and variable actuations. The common movers are motor and diesel engine. Please note the model (power, rotating speed) of the mover so as to make sure of the norms of the clutch or the belt pulley.

Water pump direction

Easy operation, low cost for maintenance; can be overally placed outdoors to work without need of machine room,saving great deal of construction fees.

Features

Simple structure, reliable use, easy installation, high efficiency, small body, light weight.
