PMK Hydro Pneumatic Boosters act as a seamless power-conversion interface, utilizing standard pneumatic facility lines to generate intense, high-pressure hydraulic output. This eliminates the need for expensive, heat-generating standalone hydraulic power packs. Designed primarily to feed the high-torque clamping systems of our advanced rotary tables, these boosters provide near-instantaneous pressure multiplication for secure and rigid workholding during heavy machining cuts. With a compact footprint and fully enclosed design, the booster easily integrates into existing CNC enclosures or external pneumatic lines. It provides completely reliable holding pressure, maintaining constant clamping force even during sudden fluctuations in workshop air supply.

Key benefits

• Converts standard 5–6 bar shop air into powerful hydraulic output.
• Eliminates the cost, footprint, and maintenance of dedicated hydraulic power packs.
• Rapid actuation ensures quick clamp and unclamp cycles for faster part loading.
• Maintains continuous hydraulic holding pressure without continuous power consumption or heat generation.
• Compact, leak-resistant design integrates easily into tight machine enclosures.

Applications

• Powering hydraulic braking/clamping systems on Rotary and Tilting Tables.
• Driving hydraulic fixtures, chucks, and collet blocks in CNC machines.
• Press-fitting, stamping, and riveting stations requiring high force from standard air lines.
• Workholding automation in cells where hydraulic pumps are impractical.

Technical highlights

• Available in multiple intensification ratios to suit specific pressure requirements.
• Integrated high-quality seals for long-lasting, leak-free operation.
• Includes fluid level indicators and easy top-up access points.
• Requires minimal maintenance compared to motorized hydraulic pumps.
• Can be paired with pneumatic solenoid valves for automated CNC control.
