Single-stage double-suction centrifugal pump

It is on both sides of the water from the impeller single-stage double-suction centrifugal pump because the pump cover and horizontal joints are assembled , also www.dongfeng-motor.com known as horizontal centrifugal pumps . Compared with the single-stage single-suction centrifugal pumps , high efficiency, large flow, high head . But bulky, cumbersome , generally used for fixed operations. Applicable to the hills , plateaus middle of electric vehicle motor irrigated area , also used in factories, mines, urban drainage and so on.

Single-stage double- suction centrifugal pump has an S -type , Sh type , SA type , SLA type several models , S-type and Sh -based 24v motor distinction , from the drive end , S -type pump is clockwise rotation , Sh type counterclockwise the direction of rotation. SLA is a vertical -type single-stage double-suction centrifugal pump.S- flow pump performance range from 160 to 18,000 m3 / h , head 12 to 125 meters , inlet diameter of 150 to 1400 mm , speed 2950,1450,970,730,585,485,360 rev / min .
(1) D -type flow pump performance range of 6.3 to diesel generating 720 m3 / h , head 16 to 600 m , water caliber : 50,75,100,125,150,200 mm, of which 50 to 125 mm for the high speed pump 2950 rev / min , 150 to 200 mm pump speed of 1480 rev / min .

( 2 ) Structure type D -type multi- stage centrifugal pumps are horizontal multistage ( 2 to 12 ) , single-suction impeller , the pump is segmented . When the first-stage double suction impeller with DS said that when there are two requirements simultaneously speed, low speed with the DA said , for boiler feedwater multistage centrifugal pump , with the DG said .
