1. Special pumps for hydroelectric power industry, with medium/high pressure reaching to 63 bar
2. Double outlets design, with more convenience for on-site pipe fitting;
3. Removal of the whole pump core assembly (with the motor lifted apart) allowable, with convenient on-site maintenance；
4. Strong self-priming capability, stable operation, low noise and smooth flow
Specially designed for hydro power industry
HSMJ series three-screw pumps are special pumps for hydropower industry. They are designed and manufactured in accordance with GB/T10866-2002 and are developed on the basis of HSN series three-screw pumps.
The three-screw pump is fixed in the pump body (bushing) by the meshing of one active screw and two driven screw. When the active screw rotates under the driving of the prime mover, the main screw and the driven screw form a sealing chamber under a certain length of the meshing helical surface. The driven screw rotates because of the pressure difference between the two sides of the helical surface and is driven by the conveying liquid medium. At this time, the conveying liquid enters the suction port of the pump. The axial direction uniformly and continuously reaches the discharge chamber, thus achieving the function of conveying liquid medium.
