Water Ring Vacuum Pump

Water Ring Vacuum Pump

2BEC series water ring vacuum pump is used to pump air or other non-corrosive, insoluble in water, does not contain solid particles of gas. In order to form a vacuum or pressure in a closed container to meet process requirements.

Multistage Water Pump

Multistage Water Pump

Multistage pump is a type of centrifugal pump in which the inlet and outlet sections and the middle section are combined through a pull rod. Its output water pressure can be very high, and it also relies on the rotation of the impeller to obtain centrifugal force, thereby transporting materials. When the gas density reaches the working range of the mechanical vacuum pump, it is extracted, thereby gradually achieving high vacuum. Multistage pumps achieve suction, compression and exhaust by changing the volume of the pump cavity, so they are variable-volume centrifugal pumps.

Centrifugal Pump

Centrifugal Pump

The split-case pump (split-case circulation), also known as the single-stage double-suction centrifugal pump, is mainly characterized by a large flow rate of the conveyed medium. The working principle of the split-case pump operation: The impeller is installed in the pump casing and fastened to the pump shaft, which is directly driven by the motor. There is a liquid suction pipe connected to the suction pipe in the center of the pump casing. The liquid enters the pump through the bottom valve and the suction pipe. The liquid discharge port on the pump casing is connected to the discharge pipe. When the rotational speed of the pump is constant, its head and flow rate are related to the diameter of the impeller.
