The rod type oil well pump designed and manufactured by our company is one of the main oil well pump products. It is designed and manufactured according to standards such as PI Spec 11AX-2006, GB/T18607-2017, SY/T5059-2009, etc. According to the support and fixation form of the pump, it can be divided into three types: moving barrel bottom fixed rod type oil well pump (RWT or RHT), fixed barrel bottom fixed rod type oil well pump (RWB or RHB or RXB), and fixed barrel top fixed rod type oil well pump (RWA or RHA).
The biggest advantage of a rod type oil pump is that during operation, the pump can be lifted out of the wellhead together with the pumping rod without affecting the tubing string. This way, homework time can be saved by more than half, thereby reducing homework costs.
Due to the structural characteristics of the rod pump, it is suitable for use in small displacement oil wells with deep pump hanging.
