Product Reviews

The three-screw pump consist one rotor and two idlers, in a precisely bored pump casing insert, which ensures high pumping efficiency and high suction power.
As the double-start screws meshes, a continuous axially moving voids/pockets generate, which traps the liquid inside it, and hence transfers the fluid, where it required.
These pumps permits an even axial flow without pulsation and silent pumping operation even at a high speed.
Axial loads on the rotor are often compensated by an adequate design of the bearing and all the radial forces are self-compensated.
Further, size of a rotor kept small in the design, which enables these pumps to run at a higher speed with direct coupling to the prime mover.

Installation: Outdoor or Indoor
Environment - Industrial, Marine
Bearing:Internal
Sealing Option: Mechanical Seal
Mounting:Horizontally or vertically mounting (foot on demand)
Direction of rotation: CW(standard), CCW(on request)
Ports location: Radial or axial inlet and radial outlet for standard direction of rotation
Relief valves: Built-in (optional)
Driving unit: Pump can be connected with the prime movers by means of flexible coupling or gear box or pulley drive
The care must be taken that pumps are do not run dry.
