DP Self-priming deep well pumps consist of an ejector unit and a centrifugal pump.The ejector unit can be put in a 4″diameter well.These pumps are suitable to convey clean water or non_aggressive chemical fluids.They are suitable to pump water from deep well and supply water automatically by pressure tank and pressure control.It is always advisable to install a foot valve with a strainer on the bottom of inlet pipe.

APPLICATIONS

– Self priming water pumps for deep suctions up to 25m to be used in case of important water level gaps.
– Suitable to drain water from wells and in domestic fittings by small and medium sized tanks.
– Before installing the pump verify that all pipes (iron, plastic or rubber) are clean inside so to avoid any obstruction to the ejector nozzle. At the foot of the ejector must be installed a foot valve or a check valve. Installed the pump, fill completely both pipes and pump body with clean water. To preserve an efficient priming it is necessary a certain pression in the circuit, therefore it is recommended to install a membrane tank at the delivery of the pump.
