KRAL Screw Pumps for Transfer Applications.

The economical solution for the delivery of oils.

KRAL screw pumps are in demand thanks to their compact design. In operation, our pumps are quiet, offer low pulsation and are highly efficient.

KRAL pumps are especially suitable for the transfer of oils. The pumps can handle a wide range of viscosities and differential pressures. With a high flow rate and an excellent NPSH value, KRAL screw pumps are manufactured in accordance with European and American standards.

KRAL three screws pumps offer a significant price advantage compared to other types of pumps and are used to flush the pipe system with separated crude oil from the storage tanks on a regular basis. KRAL two screw pumps also deliver aggressive and contaminated liquids.

Our screw pumps are well suited for pipeline booster applications in pumping stations. Due to their design, KRAL pumps can handle oils with a
wide range of viscosities and can generate high differential pressures even when pumping very light oils.
