Hydro prokav KYM KH Series

Hydro prokav
KYM KH Series


Hydro Prokav progressive cavity pumps are compact, rugged and powerful. They are available in different power classes and material of construction. They prove their value world-wide in public and industrial waste water treatment and waste disposal . They provide optimum solutions for transferring fluids in the chemical and petrochemical industry, the food industry, the cosmetics industry, the paper industry, in civil engineering, mining, industrial processing and everywhere where the conveyed product is too viscous and with too poor flowing properties to be pumped by other pumps.

Hydro Prokav pumps are self-priming positive displacement pumps. They consist of two elements: the rotating eccentric screw and the fixed stator. The medium is conveyed with low pulsation and turbulence. In the conveying of abrasive media an advantage is achieved by the flexible choice of materials for the rotor and stator.

The flow rate is proportional to the speed of rotation. Increasing the number of stages raises the pump pressure proportionally. The design allows pumping in both directions, a high suction lift and gentle conveying. Due to the numerous combinations of materials for the rotor and the stator and the gentle conveying with extremely low shear forces, the progressive cavity pumps are also highly suitable for measuring and metering tasks.
