Oil Field Specified Equipment API Rotary Barrel Pump

Specifications 1.applied to oil wells where salt dposition is serious 
2.avoid sand blocking or filling 
3.oil outlet resistant is small.   Working Principle It is similar with common oil well pump. The liquid in the well will enter the pump through the bridge oil inlet valve 8 during the oil well pumping process and then discharged to the pump through long plunger 4.   Sand control: The sand grain enters the sand setting pipe 11 below the pump through the ring space between the external sand pump 6 and pump cylinder 3 and some sand grains in the pump cylinder will be brought outside the pump by oil flow due to the short pump cylinder. If pumping is interrupted in the midway, the sand contained in the liquid in the oil pipe of pump will also enter the sand setting pipe so as to avoid sand blocking or filling.   Main Products:   Following are our main products:
