OPERATING PARAMETERS

Flow:100~1020 m³/h

Head:92~102m

Revolving speed： 1485 r/min

STRUCTURAL FEATURES

The pump is designed with a vertical barrel structure with both the pump base and the pump barrel installed at the base at the same time;

The inlet and outlet of the pump are arranged at an angle of 90°at the same horizontal line;

This pump is designed with three stage impellers in total with each impeller being of single suction, impellers arranged in the same direction and inducers designed in front of the first stage impellers;

View from the suction inlet, the pump rotates clockwise;

The shaft seal is cartridge mechanical seal, and O-rings are adopted as static seal;

Metal diaphragm coupling are adopted to connect the pump to the motor; The surface overlaying of the guide bearing is nickel,chromuium,boron and silicon alloy with wear-resisting, corrosion resisting and heat resistance and so on, so it can meet the operation under transient state of startup and shutdown, cold water running, hot water running, thermal transient, small flow and running with contaminated water. Upon transient friction between the pump spindle and the guide bearing, the surface overlaying of the guide bearing plays a role of wear layers, ensuring the safety and stability of the containment spray pump set during operation.
