HP08-00 Manual Hydraulic Pump
1. Product Overview
The HP08-00 is a compact portable manual hydraulic pump serving as a standalone power unit for miniature hydraulic circuits. It generates steady high-pressure oil output via repeated strokes of the hand lever, requiring no external electric or pneumatic power supply. Matched with 08-size threaded cartridge valves, it fits small fixture clamping, on-site circuit commissioning for construction machinery, emergency pressure boosting/release and field maintenance tasks, and is a common spare part for off-grid hydraulic operations.

3. Working Principle
Pushing the long lever drives the internal plunger to reciprocate. On the upstroke, the plunger draws oil from the reservoir; on the downstroke, the chamber volume shrinks to build pressure and deliver pressurized oil to downstream valves or actuators. The lever resets automatically for the next suction cycle. Sustained pumping maintains stable system pressure, and pressure can be held steadily with a cut-off valve for short-cycle clamping or jacking jobs.
4. Key Advantages
1. Works independently without mains power, ideal for field maintenance and power outage emergencies
2. Labor-saving lever design reduces fatigue during frequent pressure adjustment
3. Standard 08 interface is fully interchangeable with HSV/SHF/DHF 08-series cartridge valves for compact custom circuits
4. Small footprint allows integration into mini valve blocks and portable tooling
5. Oil-resistant sealing material resists aging, with minimal routine maintenance and low failure risk
5. Typical Applications
- Clamping and pressure retention for small hydraulic jigs and fixtures
- On-site commissioning, emergency pressurization and pressure relief for construction machinery cartridge valve loops
- Micro hydraulic jacking and small actuator drive
- Hydraulic system testing and maintenance for agricultural machinery and compact industrial equipment
