PUMP ASSEMBLY

摘要

A hydraulic pump assembly (1) includes a hydraulic motor (2), a housing (3), a progressing cavity pump (4), a flexible coupling (5), a porting block (6), hydraulic fittings (7, 8), a connector conduit (9), a filter (10), a pair of hydraulic lines (40, 41) and a discharge conduit (42). In use, the assembly (1) is lowered through a narrow bore hole until the filter (10) is fully submerged in water. A free end of the discharge conduit (42) is placed in a water collection reservoir. The hydraulic motor (2) is then driven using a hydraulic pump. The hydraulic motor (2) turns the rotor (50) and water is drawn in turn through the mesh screen (61), through the adapter conduit (9), through the inlet (16), through the chamber (14), through the outlet (12), through the stator (11), through the discharge outlet (51) and through the discharge conduit (42).
