Triple screw pumps with external or internal bearing are available in horizontal or vertical constructions, with or without heating arrangements, and have single mechanical seals for shaft sealing.
They handle all neutral lubricating liquids, have a compact space-saving design, and are self-priming.
Due to the precise manufacture of the screws and their profile, the possibility of achieving high suction lift is ensured.
They operate continuously and run noiselessly.
