MAIN APPLICATIONS:
Utilized in all segments of industry where lubricating liquids are pumped that do not contain abrasive components, and which will not chemically attack the pump materials, eg. heavy and diesel oil, circulation of lubricating and hydraulic oils.
Value Propositions:
- Long service life :Hardened and ground screws; hydraulically driven idler spindles that are not subject to any wear.
- Reliable operation : As overload protection a built-on- pressure relief valve is possible.
- Low maintenance : Internal bearing lubricated by pumped liquid or external bearing grease lubricated.
- Easy maintenance : Complete insert unit dismountable. The pump casing remains in the piping.
- Flexible configuration : Shaft sealing alternatively by shaft seal rings, mechanical seal or magnetic coupling according to the operating conditions.
Strengths of the technology:
- High pressure boost capabilities even when handling low viscosity fluids
- Pump with one of the highest overall efficiencies when aligned with only three rotating parts
- Virtually pulse-free flow with extremely low vibration and noise levels
General advantages of the three-screw pumps at a glance:
- Self-priming
- Virtually no pulsation
- Wide viscosity range
- High thermal resistance
- Low operating noise
- Very good efficiency
- Low wear
- Reliable during operation
