SKB self-priming pumps
Applications
Self-priming rotodynamic, pumps with side ring channel and open impeller, designed for pumping liquids within the corrosion resistance limits of materials used for their construction. Their greatest advantage is the self-priming feature, with suction pipe priming not necessary. The pump gains its self-priming feature after prior priming with liquid.
Pumps can operate in transportable equipment and with 50 Hz to 60 Hz motors.
SKB pumps can be used in:
- waterwork systems,
- individual farms,
- industry.
