Performance parameters
Diameter DN125~ 800mm
Flow rate Q can reach 10000m/h
Head H up to 180m
Working pressure P0.4 ~ 6.4MPa

Design Features
The pump body is an axially split structure, and the suction and discharge pipes are located in the lower half of the pump body. The entire pump rotor can be removed for maintenance without dismantling the piping and piping valves.
The lubrication form of the bearing is thin oil lubrication, and the non-drive end bearing can also bear the residual axial force.
Shaft seals can be packing or mechanical seals. The shaft from the overcurrent part to the impeller hub is protected by a bushing, the shaft is allowed to reverse, and the pump can be driven from both ends. Usually flanges implement GB or DIN standards.
■Cast iron
■Cast steel
■Stainless steel
■Other special materials can be used upon request

The ZTDS pump needs to use a vertical drive, and the thrust load of the pump and the weight of the rotor will be supported by the thrust bearing of the pump.


The pump is a single-stage, horizontal, radial partial flow pump (also called a tangential pump), which is a special centrifugal pump. Adopt bracket structure, single suction fully open impeller, axial suction and tangential discharge. Packing seal, single-end mechanical seal or double-end mechanical seal are used according to the conditions of use, and are equipped with cooling, flushing or sealing liquid systems, and the rated pressure levels of the suction and discharge flanges are the same. Viewed from the motor end, the pump turns counterclockwise.


This pump is suitable for conveying clean or particle-containing liquids, low-temperature or high-temperature liquids, neutral or corrosive liquids.
