BT-MB 25D: Screw Pump

The BT Series Screw pumps are self-priming positive displacement pumps, with three
spindles, one driven and two idle spindles. The three spindle rotation creates sets of moving seals from suction to discharge. These sets of seals form fully enclosed cavities moving axially and softly from the inlet to the outlet. This pumping design and construction enables noiseless fluid handling without pressure pulsations and turbulence.
