Head: up to 2,000m  (6,560ft)
Design Pressure (P): 10.0~35.0MPa
Working Temperature: -40~+200℃

Structural Features
DMS 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.
