Triple Screw Pump Liners

Growsysgroup is spearheaded in Triple Screw Pump Liners since 1990. The gathering presented tighten siphons 1970 predominantly for power plant applications. From that point forward a great many Screw siphons are provided and appointed under direction to famous European nations now and again.

Triple Screw Pumps are self-priming positive displacement pumps with external or internal bearing.

The pump consists of three Screws, one Main Screw and two idlers; one externally lubricated bearing, capable of handling thrust loads induced by high inlet pressure; one balanced mechanical seal; a liner; a casing and a bearing/seal housing.

OPERATING PRINCIPLE

  1. The main Screw (coupled to driver/motor) performs the pumping work, while the idlers act to seal off the pumping chambers. The torque is transmitted to the Idler Screws by a rolling contact.
  2. The screws are in contact with each other as well as with the surrounding casing. Subsequently, the medium must always have certain lubricating properties. The pumped fluid creates a barrier between the rotating elements, preventing metal-to-metal contact of the rotating elements. The liquid film also supports the Screws in the liner, eliminating contact between the Screws and the liners.
