Structure: fixed, mobile

Diesel engine speed: 960-3000r/min

Diesel engine brand: international brand, domestic brand

Main application: mine drainage, engineering city water supply and drainage engineering, fire fighting system, etc.

Pump unit form: horizontal, single-suction, multi-stage centrifugal pump.

It has the characteristics of high efficiency, wide performance range, safe and stable operation, low noise, long life, convenient installation and maintenance, etc. For transporting clean water or other liquids with physical and chemical properties similar to water. It can also be used to transport hot water, oil, corrosive or abrasive media by changing the material and sealing form of the pump's flow-through components and adding a cooling system. The axial force is balanced by the balance plate. Shaft seals generally use packing seals, and mechanical seals can also be used according to user needs

Working principle:

The driving machine drives the impeller to rotate through the pump shaft to generate centrifugal force. Under the action of the centrifugal force, the liquid is thrown to the outlet of the impeller along the blade channel, and the liquid is collected and sent to the discharge pipe through the volute.

The liquid obtains energy from the impeller, which increases the pressure energy and velocity energy, and relies on this energy to transport the liquid to the work site.

While the liquid is thrown toward the impeller outlet, a low pressure is formed at the center of the impeller inlet, and a pressure difference is generated between the liquid in the suction tank and the center of the impeller.The liquid in the suction tank is under the action of this pressure difference. It continuously enters the impeller through the suction pipeline and the suction chamber of the pump.
