Self-priming centrifugal pumps TOUGH TECHNOLOGY experience of a lifetime // innovation for tomorrow High and dry with j self-priming centrifugal pumps J pumps are self-priming centrifugal pumps with open impeller handling large diameter solids and replaceable wear plates. They have easily opened inspection covers and externally lubricated mechanical seals. • Simple construction. Only one moving part: the impeller • Easy inspection of impeller • Quick self-priming without foot valves. The pump self-primes automatically to heights of up to 7.5 m • Large diameter solids handled • High resistance to abrasive liquids. The wear plate is easily replaced and can be covered with an abrasion and oil resistant rubber facing. • Externally lubricated mechanical seal. Lubrication prevents damage during dry running and stops leaks of air or liquid along the shaft. • Easy to install. Only the suction hose is immersed in the liquid. The pump can be set up high and dry in the most convenient position for inspection and maintenance. • Long life. The parts subject to wear can be easily replaced one or more times to restore the original performance. Applications J pumps are used when one or more of the following are required: • self-priming • solids handling • resistance to abrasion J pumps can handle liquids up to a viscosity of about 50 mm2/s (cSt).
