Ultra-High Pressure Pneumatic-Hydraulic Pump for Marine Ship Systems

The Ultra-High Pressure Pneumatic-Hydraulic Pump is an essential tool for marine engineering and shipboard maintenance operations. Designed to generate hydraulic pressures up to 700 bar (10,000 psi), this air-driven pump provides reliable power for a wide range of deck and engine room applications, including hydraulic torque wrenches, bolt tensioners, flange spreaders, and jacking cylinders. Its compact, rugged construction makes it ideal for use in confined spaces and harsh marine environments.

Featuring a two-stage pumping system, the pump delivers rapid oil flow at low pressure for fast cylinder approach, then automatically shifts to high pressure for maximum output when required. The pneumatic drive eliminates the need for electric power, making it safe for use in hazardous areas where spark-free operation is critical. With precise pressure control and minimal air consumption, this pump offers an efficient and cost-effective solution for ship repair yards and offshore vessels.

The unit is supplied complete with a hydraulic pressure gauge, air filter/regulator, and suction strainer, ensuring you have everything needed for immediate operation. Whether you are performing routine maintenance or emergency repairs, this dependable pneumatic-hydraulic pump enhances productivity and safety on board any merchant or naval vessel.

Frequently Asked Questions

What is a pneumatic-hydraulic pump used for?

It is used to power hydraulic tools such as torque wrenches, bolt tensioners, and jacks. It converts compressed air into hydraulic pressure, making it ideal for shipboard maintenance, flange bolting, and heavy lifting.

What air pressure is required to operate this pump?

The pump operates on a standard shipboard compressed air supply of 6–8 bar (90–120 psi). It includes an air filter/regulator to optimize inlet pressure.

Can the pump be used in explosive atmospheres?

Yes. Because it is air-driven and spark-free, the pump is suitable for use in hazardous areas where electric tools are prohibited. Always follow your vessel or site safety guidelines.

How do I maintain the pump?

Regularly check hydraulic oil levels, keep air filters clean, and inspect hoses for wear. After use, disconnect the air supply and relieve hydraulic pressure. Periodic servicing by a qualified marine engineer is recommended.
