Small Manual Hydraulic Pump
Compact High-Pressure Source
Large pump stations often struggle to fit inside mine cages, narrow pipes, or isolated maintenance bays. The Small Manual Hydraulic Pump weighs 10 kg and features a detachable handle for single-hand transport. By manually driving the plunger, it generates high-pressure fluid for small-scale tensioning, equipment maintenance, and standby duty. Its compact footprint and lack of power cords make it a practical backup hydraulic source for confined spaces.

Pump Ergonomics and Fluid Flow
Feature 1: Weighing 10 kg without hoses, the pump allows easy lifting to any work site, reducing operator fatigue during transport.
Feature 2: Internal oil circuits are kept clean during assembly, making the pump resistant to external dust and debris in temporary work areas.
Feature 3: The fluid path balances intake and return efficiency. After the job, high-pressure oil returns quickly to the tank, reducing the time needed to reset the jack.

Specific Use Cases
This unit fits inside mine cages, pipes, or tight maintenance shops where larger stations cannot operate. As a replacement or backup pump for manual cable bolt tensioners, it travels easily with repair crews. In overseas retail and parts markets, its simple design allows end-users to purchase and install replacements, minimizing after-sales costs.
Sealing and Export Packing
The pump uses high-pressure seals tested for pressure holding and aging, keeping fluids contained during storage. The factory supports custom tank volumes, pressure gauge ranges, and connection types. All moving parts undergo precision machining and hardening. The pump ships in solid wood crates with bubble-wrap protection for moisture and shock resistance. Custom shipping marks and clearance documents are available.
Procurement Inquiries
Q1: Why does the pressure gauge pointer fluctuate?
A1: Slight fluctuation is normal from the plunger pump's pressure pulsation. If the fluctuation is excessive, air may be trapped in the system. Repeatedly actuate the handle to purge the air.
Q2: What is the proper storage procedure?
A2: Drain the old oil and store the handle separately. Keep the pump in a dry, clean environment to prevent seal degradation.
