The 4T series is produced in a cast steel casing with a combined foot/flange mounting arrangement. The pump is primarily used for medium pressure gas sealing applications on compressors.
The 4U series pump is intended primarily as a medium pressure fluid power pump. It is available foot or flange mounted and is suitable for cyclic pressure service.
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.
