M - Self Primingpumps (with external ejector for deep well Ø4)
APPLICATIONS
Water supply to remote dwellings i.e. farmhouses, general water supply, pressurized water using pressure vessels (autoclaves), horticultural irrigation, mist irrigation, dairy, farm also industrial applications. Water transfer and garden watering applications.
Note, a foot-valve must be fitted to the ejector, also with a valve mounted on the outlet of the pump to ensure a suitable counter pressure during operation. The pipes connecting the ejector and the pump body must always be filled up before starting.
