Detail

Overview
DK type open centrifugal pump is a multi-stage, single suction, horizontal open centrifugal pump in the pump shell.
Transporting clean water or non-corrosive liquids. Medium temperature 80 ℃.
Performance range
Flow rate:Q = 244 ~ 498m ³/h
Head: H = 64.5~228m
Drive
The pump is driven by an electric motor through an elastic coupling. The pump rotates clockwise as viewed from the drive end.
Model Description

Structure
DK type pump is a horizontal, horizontal single-suction centrifugal pump. The impeller is arranged symmetrically to balance the axial force thrust. The suction port and the discharge port are cast together with the lower half of the pump body, and the rotor parts of the pump can be easily inspected without disassembling the pipeline and the motor.
