Hand vacuum pump GEKO model 3 (10) — manual vacuum / pressure tester

The GEKO Hand Vacuum Pump model 3 (10) is a manual vacuum and pressure tester designed for portable diagnostic and maintenance tasks on hydraulic and pneumatic systems. Lightweight and hand-operated, this tool enables controlled creation of vacuum or positive pressure for functional testing, fluid bleeding, and component service where an electrical pump is unnecessary or impractical.

Advantages

The pump provides precise manual control over vacuum and pressure levels, enabling safe and gradual testing of seals, hoses, valves, and brake systems. Its compact and portable design allows use at the workbench or on-vehicle, and the mechanical operation requires no power source, increasing reliability in remote or low-resource environments. The construction supports repeated use for routine maintenance and diagnostic checks.

Suitable for

• Brake system bleeding and vacuum-assisted brake maintenance
• Leak testing of hoses, fittings, and seals in hydraulic and pneumatic circuits
• Functional testing of vacuum-operated components and sensors
• Small workshop maintenance and on-site service where portability is needed

Key specifications

• Operation: manual hand-operated vacuum and pressure generation
• Application: compatible with hydraulic and pneumatic component testing and fluid bleeding
• Portability: compact, lightweight for handheld use and mobile service
• Control: adjustable by hand for gradual vacuum/pressure application
• Materials and finish: durable construction suitable for workshop environments

How to use

Connect the appropriate hose and fitting to the component or circuit to be tested, ensuring a secure seal. Operate the hand pump by pulling and pushing the handle to generate the required vacuum or pressure while monitoring the component for leaks or response. Maintain steady, controlled strokes to reach and hold target pressure levels; release or vent the system slowly when the test is complete. After use, disconnect fittings, wipe the pump clean, and store it in a dry place.

Usage recommendations

When performing brake bleeding or leak tests, verify compatibility of fittings and hoses with the system fluid and operating pressures. Use appropriate eye and hand protection, work on a stable surface, and avoid exceeding component pressure ratings. Regularly inspect seals and hoses for wear and replace them if damaged to ensure accurate test results and safe operation.
