PM Hydraulic Hand Pumps

Product Overview

PM hydraulic hand pumps are portable manual hydraulic power units. Without electric power supply, operators can generate hydraulic pressure by pushing the hand lever. This series is commonly single-acting type, used to supply pressure for hydraulic cylinders, clamping fixtures and test tools. It serves as a convenient backup power source for your hydraulic system and Machine.

Technical Specifications (Typical PM model)

- Max working pressure: 350 bar

- Pumping action: Single-acting

- Oil port: G3/8 or 1/4 NPT optional

- Pump body: Cast iron

- Hydraulic fluid: ISO VG mineral hydraulic oil

- Optional: Integral or separate oil tank, pressure gauge, safety relief valve

- Operation: Two-speed design (large flow low pressure for fast advance; small flow high pressure for heavy load)

Working Principle

Swing the hand lever to drive the internal piston reciprocating. At low pressure stage, large flow oil pushes the cylinder for rapid travel. When load rises and pressure increases, it automatically switches to high-pressure small flow mode to save manpower. Built-in unloading valve releases pressure to retract the cylinder after operation.

Key Features

1. Two-speed pumping design, less hand force during high-pressure operation

2. Built-in overpressure relief valve for safety protection

3. Robust cast iron housing, reliable sealing, long service life

4. Compact and lightweight, easy to carry and install

5. Simple structure, low failure rate and convenient maintenance

6. Available with different tank capacities and pressure gauge options

Application

Workshop clamping, equipment lifting, hydraulic pressure testing, machinery maintenance, agricultural equipment, emergency hydraulic operation for mobile Machine and hydraulic system.
