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).
