Abstract

A submersible well pump assembly has a pump housing with a pump discharge on upper end. A pump barrel is located within the pump housing, defining an annular passage between the barrel and the pump housing. A plunger is reciprocally carried in the barrel. A motor mounted below the pump housing and operatively couples to the plunger causes the plunger to reciprocate between an upstroke and a down-stroke. A valve and porting arrangement directs well fluid in the barrel below the plunger into the annular passage and out the discharge during a down stroke of the plunger. The valve and porting arrangement admits well fluid into the barrel below the plunger during the up stroke of the plunger. A connecting rod extends between the motor and the plunger. The connecting rod is in tension during the down-stroke.
