Integrating the both advantages of the simple structure of the centrifugal pump and the strong capacity of the positive displacement pump, HP-ZAP pump use the friction force and the centrifugal force to transport the fluids. Hitherto, the principle of most pumps is all the same that the mechanical parts (i.e., gears, plungers, rotors, blades) impact the fluids to make the fluids movement.

For high viscosity fluids, high abrasion fluids, high-solids and/or gas-entrained fluids and shear sensitive fluids, the impact force is dangerous, which will bring pulsation, wear, piping damage. The HP-ZAP pump can utmost solve all this problem and more reliable, more efficient, more costly, longer life cycle and less maintenance.
The unique non-impingement technology ensures the bubbles in gas-entrained fluids will not burst in pumping. Moreover, there is no radial and axial force so that the pump needs less part replacement and repair.

The HP-ZAP pump is the best choice under fluids,
● High viscosity fluids with large size solids, all municipal and industrial wastewater and slurries.
● High abrasion fluids, lime slurry, mud, sand slurry, sewage and particulate mud with a content of more than 80%.
● Gas-entrained fluids or other substance content fluids, DAF mud and other types of anaerobic mud and others.
● Large size solids content and long fibre content fluids: urban wastewater containing debris, weeds, plastic sheets.
● Pulp and paper industry.

This pump is designed with full consideration of the versatility and interchangeability of the feed pump parts. According to different boiler feed pump datum (datum within some range), suction casing, stage casing, discharge casing, bearing body parts, the shaft seal parts and the shaft seal parts are same as common parts and only the number of stages, the dimensions and profile of flow parts such as the impeller and the inducer are different, which can greatly shorten the design and producing time and also shorten the lead time.
