PH 45 ES (50 Hz) - Peripheral horizontal end suction pump


The PH ES rangel of peripheral pumps with horizontal suction and vertical delivery are designed for continuous operation at 5 l/min and above.  They offer a range of seal and motor options, providing flow rates up to 40 l/min and heads up to 42 metres.


  • The range of PH ES peripheral pumps are designed to pump clean, fresh water. Other clean, non aggressive, non explosive liquids with similar characteristics to water may be pumped. The range can be used for pressure boosting, liquid transfer and distribution.
