China Diesel Engine Multistage Centrifugal Fire Fighting Pump

1.Product Description
The D series horizontal multistage centrifugal pump is composed of certain single stage pumps connected in series. With large output water pressure, the centrifugal force is obtained through impeller rotation. When the air is pumped out and concentration meets the operation requirement, high vacuum is obtained.
The air suction, compression and exhaust of the mechanical vacuum pump are conducted based on the volume change of the pump cavity. The distinct feature of the horizontal single suction centrifugal pump is that the stage quantity can be adjusted according to practical working pressure.
The pump is efficient, reliable, and durable with low noise performance and easy maintenance and wide scope of usages.
Our pump is applicable to deliver those fluid without solid, particles or any other suspended stuff, water for instance. While oily and corrosive or solid-contained fluid can be pumped by means of material modification, sealing methods, and cooling system adding.
