Walker Water Pump Product Introduction:
Two stage centrifugal pump is an important type of centrifugal pump. This type of pump impeller actually consists of two back-to-back impellers, from which the water flow into a volute.
Single stage double suction pumps works just like two same diameter end-suction pumps work at the same time, so its flow quantity can be doubled by using the same outer diameter impeller.
The horizontal split structure of pump shell makes easy inspection and maintenance possible. Meanwhile, the entry end and exit end of double suction pump are in the same direction, being perpendicular to the pump shaft, which is helpful for the layout and installation of pumps and water pipes; double suction pump is characterized by symmetrical impeller structure and non axial force, so it can run more smoothly and can satisfy the operating requirement of mass flow and high lift.
