A triple screw pump is a positive-displacement rotary pump. The main drive screw (center) rotates, driving two idler screws (both sides) in synchronized reverse rotation. The screw threads and pump liner form continuous, isolated sealed chambers. As screws turn, chambers expand at suction (vacuum draws fluid) and contract at discharge, pushing fluid axially from inlet to outlet with zero/minimal pulsation and high pressure.
✅ Triple Screw Pump: High Pressure, Zero Pulsation, Ultra Quiet
✅ Ideal for marine l**e, hydraulic oil, fuel oil & heavy viscous fluids
✅ CE/DNV certified, self-priming, low maintenance, long life
✅ Factory direct, custom flow/pressure, global after-sales
