DMS series axial split multistage pump is multi-stage, horizontal, axial split; center line installation, support at both ends. The impeller is installed back-to-back to balance the axial force, the double volute of the pressurized water chamber is designed to balance the radial force, and the first-stage double-suction impeller is designed for low cavitation conditions.
DMS series axial split multistage pump widely used in crude oil, petroleum products, water, seawater and other liquids that are pure or contain a small amount of impurities; Crude oil, refinery, petrochemical, water injection, pipeline, boiler feed water, condensed water and metallurgy, etc.
Flow: 5~2700 m3/h
Head: up to 2,600m
Design Pressure (P): 10.0~35.0MPa
Working Temperature: -40~+200℃
DMS series axial split multistage pump is a horizontal multistage split casing pump with completely symmetrical arrangement and reliable hydraulic performance, able to economically and reliably work without fault.
The inter-stages adopt ring-shaped flexible seal and the inter-casings adopt thin pad to prevent from leakage caused by high pressure and temperature.
When the temperature variation of the pump casing, inlet and outlet, the horizontal split casing can minimize the nonaffine deformation, which has a minimum effect on the precision.
The inlet and outlet are designed on the bottom casing and the inner pump rotor can be disassembled or assembled without moving the inlet and outlet pipes.
