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.
 
API insert pumps with either a cup or mechanical bottom anchor 
(hold-down). These are recommended for deep wells with low fluid 
levels. These pump assemblies are installed in the well on the end 
of the sucker rod string and seated in the seating nipple installed in 
the tubing string at a predetermined depth.
Features
? General purpose API pump
? Number of available accessories to meet application 
needs- Balanced pressure around the barrel overcomes the 
disadvantages of a top anchor pump.
? Fluid has only to pass through the anchor and standing 
valve to be in the producing chamber of the pump. The top 
anchor pump shares this advantage.
