Hydraulic Fittings

PM12-25-45byB-s is multi-displacement single-acting plunger manual hydraulic pump fitted with both relief valve and overflow unloading valve, compatible with PM12/PM25/PM45 three displacement specifications.

PM12-25-45s is multi-displacement single-acting plunger manual hydraulic pump equipped with built-in adjustable relief valve, covering three optional displacements: PM12 / PM25 / PM45.

PM12-25-45e is interchangeable displacement single-acting plunger manual hydraulic pump without built-in valve, covering 3 displacement specifications: PM12 / PM25 / PM45.

PM50byB-e-s is high-displacement single-acting plunger manual hydraulic pump with built-in adjustable relief valve. Reciprocate the operating handle to drive inner plunger for reciprocating movement, changing pump chamber volume to realize hydraulic oil suction and high-pressure output, converting manual mechanical energy into hydraulic power.

PM50s is high-displacement single-acting plunger manual hydraulic pump fitted with built-in adjustable relief valve. Reciprocate the handle to drive internal plunger, varying pump chamber volume to complete oil suction and high-pressure fluid output, converting manual mechanical energy into hydraulic power.

PM50e is large-displacement single-acting plunger manual hydraulic pump without built-in valve. Reciprocating the handle drives internal plunger to make reciprocating linear movement, changing pump cavity volume to finish oil intake and high-pressure hydraulic output, converting manual mechanical power into hydraulic energy.
