OLEO PNEUMATIC PUMPS

Product catalog summary

General Specifications
HP Series Oleo Pneumatic Pumps operate at pressures ranging from 100 to 750 bar. They feature 1/2” BSP inlet ports, 3/8” BSP outlet ports, and compressed air inlets ranging from 1/4” BSP to 1/2” BSP. The construction includes anodized aluminum components, high-resistance steel pistons, and polyurethane seals with anti-friction and anti-extrusion properties. The pumps are designed for wall mounting with galvanized steel brackets and include high-performance check valves and noise-reducing dampers.

Pump Coding
The coding system for HP Series pumps includes specifications for pump size, typology, compression ratio, and mounting type. For example, a wall-mounted, 125 mm size, double-action pump with a 32:1 oil-to-air ratio is coded as HP 2 2 D 1.

Working Diagram
The pumps are available in single and double-action configurations, each with distinct working diagrams.

System Requirements
HP Series pumps are designed to drive hydraulic devices that do not require uniform movement, delivering a pulsed hydraulic flow. They require an oil direction control system and a pneumatic feeding circuit with a filter, reducer, and lubricator.

Working Principle
The pumps operate on Pascal's principle, using compressed air to move a pneumatic piston, which in turn moves a hydraulic piston to convert air pressure into oil pressure. The hydraulic pressure is determined by multiplying the pneumatic pressure by the pump's compression ratio.

Technical Characteristics
For various pump models, the air-to-oil compression ratio is specified, with maximum oil viscosity at 10° Engler and maximum oil temperature at 80°C. The operating room temperature ranges from -10 to +50°C, with pneumatic feeding pressures between 1 and 10 bar. The inlet oil filter degree is 60 microns.

Notes
There are no immersed versions for pumps of size 200.

Oleo Pneumatic Pumps Files System Requirements HP series oleo pneumatic pumps are born to drive or pressurize all hydraulic devices that don’t require a strictly uniform movement. Its conception makes itself deliver a pulsed hydraulic flow that translates into an irregular movement of any device connected to it. HP pumps are made to deliver pressure, therefore it is necessary an oil direction control system which returns the fluid back to its tank, whenever is not required. It is also needed, a pneumatic feeding circuit with filter, reducer and lubricator to drive the pump and an tank from which...
