API RWB PUMP/Precision Insert Type API Rod Pump with Thin-wall Barrel
API 11AX subsurface sucker rod pumps (including tubing pump and rod pump) are manufactured with advanced technology and equipment imported from the U.S.A and have been granted to use the official API monogram on the pumps an its fittings.
RWB - designed for shallow depth wells.
Â
API insert pumps with either a cup or mechanical bottom anchorÂ
(hold-down). These are recommended for deep wells with low fluidÂ
levels. These pump assemblies are installed in the well on the endÂ
of the sucker rod string and seated in the seating nipple installed inÂ
the tubing string at a predetermined depth.
Features
? General purpose API pump
? Number of available accessories to meet applicationÂ
needs- Balanced pressure around the barrel overcomes theÂ
disadvantages of a top anchor pump.
? Fluid has only to pass through the anchor and standingÂ
valve to be in the producing chamber of the pump. The topÂ
anchor pump shares this advantage.
