Compared with single-suction pumps, double-suction pumps have high efficiency, large flow and higher lift. Can be divided into vertical and horizontal. The double suction pump has a compact structure, beautiful appearance, good stability, easy installation, and the bearing ensures smooth operation, low noise and long service life. After precision casting, the inner surface of the pump casing and the surface of the impeller are extremely bright and have remarkable anti-cavitation performance and high efficiency.
