Selfpriming screw pumps

Screw pumps, part of the positive displacement pump family, are most commonly utilised for the transfer of fluids with lubricating properties such as fuel, oils and lube oil. The screw pump is a versatile pump as it is able to handle fluctuating flow rates and pressures without losing efficiency

Vertical and horizontal executions

Azcue Pump BT Series

These selfpriming positive displacement pumps have three spindles, one driving and two idle. The spindle rotation creates many sets of moving seals from suction to discharge. This pumping design and construction enables a noiseless fluid handling without pressure pulsations and turbulences. Therefore they can rotate at high rotation speeds with high reliability
