3G, Three-Screw Pumps

 Three Screw Pump

Laifu offers industrial pumps such as gear pumps, centrifugal pumps and screw pumps.

Application:
The 3-Screw Pumps can be used oil transportation, lubricating motion equipment and machinery, force transferring like hydraulic lifting system, or pipeline service, it can pumping the oil like substance, and the 3-screw pumps may be found on the oil refinery factories, or water injection service in agriculture , the farmers use the pump to irrigate fields.
The screw pump is limited for transferring temperature of substance lower than 150℃,the viscosity is no higher than 3-760cst, the pumped material need no corrosive and have lubrication.

We have various screw pumps with different technical for different working required.

Description:
The screw pump is consisted of several screws, the screw pump is to rotate the screws to pump the liquid toward the direction, 3-screw pump is structured with 3 screws.

We offer vertical screw pumps and horizontal screw pumps, and driven by AC powered or DC powered, DC powered screw pumps designed for marine.

The 3-screw pumps have features of long service life without complex maintenance, no contact between among screws is no frictions to wear the screws, so the screw pumps are have long service life.

We offer the industrial pumps besides these 3-screw pumps, we have internal gear pumps, centrifugal pumps and external gear pumps.
