Suitable for many applications, very compact, robust, flexible, excellent price-performance ratio. Perfectly adequate for pressures up to 16 bar. All products of the K series have an internal safety valve and can be ordered with DIN flanges in inline arrangement (except KFT and KFN). Like all KRAL screw pumps, the pumps of the K series are self-priming, deliver with low-pulsation and, in contrast to other functional principles, can be easily regulated.
Compared to other types of pumps, KRAL screw pumps convey a wide variety of media, qualities and viscosities in consistently high quantities, even at high differential pressure. Further advantages are the compact design and the high flexibility.
