Product Description

You are welcomed to come to YINJIA factory to buy the latest selling, low price, and high-quality deep well JET pump. We look forward to cooperating with you. The deep well JET pump are regarded as one of the best pumps for deep well. In fact they consist of two pumps connected in series, one is ejector-pump and the other is centrifugal pump. The ejector pump is lowered in well and connected to the centrifugal pump body by two pipes. The most remarkable character is that they can be used to supply clean water from extremely deep well. To ensure adequate counter-pressure, it is always installed with a foot valve and a filter on the suction opening. These pumps are popular in Indonesia, Thailand, Vietnam and other South-east Asia countries.


Product Feature And Application

-Selfpriming 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.
