KRAL Screw Pumps.KRAL AG has a broad selection of pumps to satisfy customer specific requirements. Innovative solutions and attention to details are our strengths.
KRAL pumps are tailor-made solutions for pumping fuels, oils, and other non aggressive liquids.
Screw pumps offer in comparison to other types of pumps, a high flow rate while occupying minimal space. This is particularly true in the case of high differential pressures. The pumps are self-priming, with very low noise and pulsation levels. Individual pumps, single stations and double stations are very compact.
