Series 12L pumps are designed for very high pressure service primarily for compressor gas sealing, fluid power and hydrostatic bearing applications. Pumps are equipped with a steel case and balanced mechanical shaft seal. This series is believed to be the world’s highest pressure capability 3-screw pump.
THREE-SCREW PUMPS
Discover our three-screw pumps – the clear choice for superior performance and versatility. The unique design with three interlocking spindles provides an extremely efficient and smooth flow, resulting in impressive overall efficiency.
In addition to excellent controllability, the self-priming pumps offer minimal pulsation and remarkably quiet operation, even at high discharge pressures.
Our three-screw pumps are true all-rounders, capable of handling a wide range of fluids of varying viscosities – from low-viscosity fluids to highly viscous substances. It’s robust design and the high wear resistance of the spindles ensure reliability and long life, making them the ideal choice for critical applications in a variety of industries.
