Product description

The pump moves with the help of the feed-back force when the pump is operating so the pump is very suitable for sucking heavy crude oil.The pump can work smoothly in a heavy crude oil with the viscosity smaller than 4000 centipoise. There is no standing valve in the pump.It is not necessary to install the oil drainers in down-hole and the well-testing and vapour injection operation can be done without lifting the tubing strings.
