It is a single -stage double -suction 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. 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.

There are several models of S -type, SH, SA, and SLA types in single -grade dual -suction cardiac pumps. The difference between S type and SH type is that from the drive end, the S -type pump is rotated clockwise, and the SH type is counterclockwise counterclockwise Rotate the direction. The SLA type is a vertical single -stage double -suction cardiac percentage.

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.

(1) The performance range of the D -type pump is 6.3 to 720 cubic meters/h, and the raising is 16 to 600 meters. 2950 rpm, 150 to 200mm pump speed speed is 1480 rpm.

(2) Structural type D -type multi -level centrifugal pump is a horizontal multi -level (level 2-12), the impeller is single suction, and the pump body is segmented. When the first -stage impeller is a double suction, use DS to indicate that when there are two speeds at the same time, it is expressed at low speeds at low speeds, and multi -level centrifugal pumps used for boiler water to water are represented by DG.
