KRAL L Series Screw Pumps.
Compact, low-wear pump up to 63 bar.
Robust, versatile and easy to maintain.
Versatile, compact and efficient like the K series, but for higher operating pressures up to 63 bar: the KRAL L series screw pump is the preferred choice for medium-pressure applications in the marine sector as well as numerous applications in the oil and gas, power generation, mechanical engineering and chemical industries. It has a spheroidal cast iron housing and is approved for use on board ships.

Other pump technologies have the disadvantage that they can only be operated at low speed due to the high risk of damage. KRAL screw pumps, on the other hand, are gentle on the medium, even at high speeds. This guarantees high operating efficiency and an excellent price/performance ratio.
All screw pumps of the KRAL L series also offer reliable startup, minimal wear, and ease of maintenance, which simplify operation. Available with magnetic coupling or external ball bearing (maintenance-free).
- Very broad range of applications.
- Flexible connection arrangement.
- Excellent suction characteristics.
- Low-pulsation delivery.
- Adjustable screw design.
- Little space required.
- Dry running protection.
- Support for different delivery heights without booster pump.
- Optional delivery direction can be changed easily for a short time.
- No need for a separate stripping system with control unit.
