  • Max. differential pressure: 25 bar.
  • Temperature range in the pumped media: -40 °C to +300 °C.
  • Housing: Ductile iron or welded steel.
  • Screws: Solid or engineered.
  • Approvals: ABS, BV, DNV-GL, LRS, RINA, others on request.
  • ATEX: Device Group II, Device Category 2.
  • Heating: Electrical, media or steam.
  • API: Manufacturing according to API 676 possible.

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.

  • 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.
