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”.

advantage

The unique impeller design and the great flow-path block-up vesisting hydraulic parts greatly enhance the ability for sewage to pass and effectively have fibre matters and solid grains passing through.

It belongs to the integrated electromechanical product with both pump and motor in one shaft to directly drive, resulting in compact structure and stable performance.

Strong applicability, suitable for conveying urban domestic sewage, industrial and mining enterprise sewage, etc.

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

Mechanical seal is made of hard wearable corrosion-proof tungsten carbide and features durability and wearbility and can safely and continually run over 800h.
