PM12-25-45e Single-acting manual pump, without valve

PM12-25-45e is interchangeable displacement single-acting plunger manual hydraulic pump without built-in valve, covering 3 displacement specifications: PM12 / PM25 / PM45. Reciprocate the handle to drive inner plunger reciprocation, changing pump cavity volume to complete oil intake and high-pressure delivery, converting human mechanical force into hydraulic energy. Its flange base design enables stable fixed installation on hydraulic power unit.Core Advantages✅ Three Displacement Optional Design

Integrated three flow options (12/25/45 series) in one pump outline; low pressure adopts large displacement for fast oil output, high pressure switches to small displacement for labor-saving operation, balancing lifting speed and hand force.

✅ Ergonomic Optimized Force Matching

Three characteristic curves on Pressure-Handle Force Diagram cover 0~600BAR working pressure; refer to orange maximum force benchmark to select matched handle length for each specification, keep operating load within comfortable range.

✅ Flange Fixed Base Structure

Flat flange mounting bottom with reserved fixing holes for easy bolt locking on equipment base, stable installation, no extra bracket needed, simplifying system assembly.

✅ No-valve Compact Layout

Without built-in directional valve, reduce spare parts cost and pipeline complexity, ideal for customized compact hydraulic stations.Application FieldsMatched with single-acting hydraulic cylinders, widely used for small lifting equipment, automobile maintenance tools, precision portable hydraulic machinery and multi-demand customized hydraulic systems with variable flow requirement.
