IMO 4VKC Series
Made in Germany
The IMO 4VK and 4SF series pumps are of rotary, positive displacement 3-screw design. Both product lines are engineered to deliver excellent performance over a wide range of fluid viscosities and system pressures.
Flow rates are proportional to rotating speed when operated within each pump's recommended pressure range. The self-priming design permits both evacuation of air from suction lines and repriming if suction is lost. Axial fluid flow, high operating efficiency and effective design practices result in extremely low airborne and liquidborne noise levels.

- Intended primarily as a medium pressure fluid pump
- Can be either foot or flange mounted in any attitude
- High tensile, close grain, cast iron casing
- Vertical and horizontal installation
- Dry installation
The 4VKC series pump is intended primarily as a medium pressure fluid power pump. It is available foot or flange mounted.
This series is available in
