It is a double -absorbing cardiac pump from both sides of the impeller. Because the pump cover and pump body are assembled by horizontal seams, it is also called an open -style centrifugal pump in the horizontal level. Compared with a single -stage single -suction fragrance, high efficiency, large traffic, and high raising. However, it is large and bulky, and is generally used for fixed operations. It is suitable for irrigation districts with medium -sized areas of hills and plateau, and also applies to factories, mines, and cities.

Dual -suction cardiac pumps include S type, SH, SA, and SLA types. The difference between S type and SH type is that from the drive side, the S -type pump is rotated clockwise, and the SH type is rotated in the counterclockwise direction. Essence The SLB type is a vertical disassembly dual pump.

The performance range of the S -shaped pump is 160 to 18,000 cubic meters per hour, the raising is 12-125 meters, the diameter of the water inlet is 150 to 1400 mm, and the speed is 2950, 1450, 970, 730, 585, 485, 360 rpm.
