QZ series submersible axial flow pump and QH series submersible mixed flow pump are the new generation products successfully developed by our company after introducing advanced technology at home and abroad and elaborately designing according to user requirements and service conditions. The hydraulic models have reached the leading level in China. Compared with the old model, the flow rate is increased by 20% - 30%, the efficiency is increased by 3% - 5%, and the cavitation resistance is excellent.
QZ and QH series pumps are characterized by large single unit flow, wide lift range and high efficiency. The submersible motor and pump body structure, which can operate underwater, has advantages that traditional units cannot match:
A: It greatly simplifies the civil engineering and building structure works of the pump station, saving 30% - 40% of the total cost of the pump station project.
B: Simple maintenance, leakage and internal winding temperature rise protection device, control cabinet can be equipped, and the operation is reliable.
C: Low noise and long service life.
Impellers and impeller seats of QZ and QH series products are made of cast iron, ductile iron, cast copper (bronze) and stainless steel, which can be selected by users according to their needs.
