It is a single-stage double-suction centrifugal pump from both sides of the impeller, because the pump cover and pump body are assembled by horizontal joints, also known as horizontal open centrifugal pump. 

Compared with the single stage single suction centrifugal pump, the efficiency is higher, the flow rate is larger and the head is higher. 

But large, more bulky, generally used for fixed operations. 

It is not only suitable for medium area irrigation areas in hilly and plateau, but also suitable for factories, mines, urban water supply and drainage and so on. 

There are several types of single-stage double-suction centrifugal pumps: s type, Shh type, SA type and SLA type. The difference between S type and Shtype is that from the driving end, the S type pump rotates clockwise and the Shtype rotates counterclockwise. 

The SLA type is a vertical single-stage double suction centrifugal pump. 

The performance range of the S-type pump is 160 to 18000 cubic meters per hour, the head is 12 to 125m, the inlet diameter is 150 to 1400mm, and the rotating speed is 2950, 1450, 970,730,585,485360 rpm. 

(1) the performance range of type D pump is 6.3 to 720m3 / hour, the head is 16600m, and the inlet caliber is 50,75,100,125,150,200mm, of which the pump type of 50125mm is 2950 revolutions / min of high speed, and the speed of 150mm pump is 1480 rpm. 

(2) the structure type D multistage centrifugal pump is horizontal multistage (2 to 12 stages), the impeller is single suction, and the pump body is segmented. 

When the first stage impeller is double suction, it is expressed by DS, when there are two kinds of rotating speed at the same time, the low speed is represented by DA, and the multi-stage centrifugal pump used for boiler feed water is expressed by DG.
