Hydraulic Pump Seals

McNeil Industries provides high-performance sealing solutions for hydraulic pumps. Our hydraulic pump seals are engineered to maintain system pressure, prevent leaks, and protect equipment from contamination. The majority of our product line is designed specifically for Permco pumps, with one part number compatible with Parker Hannifin pumps. Every seal is manufactured to meet the exact specifications of the OEM, ensuring reliable operation and long service life.

Product Line for Hydraulic Pumps

Our hydraulic pump seal offering includes 15 distinct part numbers, all of which are listed on a single page for easy reference. Each seal type is chosen to match its application in hydraulic pumps, providing secure sealing, pressure retention, and durability.

Available Seal Types Include:

• Lip Seals – Prevent fluid leakage along rotating shafts while maintaining system pressure.
• O-Rings – Serve as reliable static and dynamic seals inside the pump housing.
• Quad Rings – Four-lobed design offers improved sealing and lower friction under high pressure.
• Spring-Energized Seals – Maintain consistent contact in high-pressure and high-temperature environments.

Every seal is manufactured from high-performance elastomers, PTFE, or engineered polymers. Materials are selected for wear resistance, chemical compatibility, and temperature tolerance to ensure optimal performance in hydraulic systems.

OEM Compatibility

Permco Pumps: Most of our hydraulic pump seals are fully compatible with Permco hydraulic pumps, covering a wide range of part numbers below. These seals fit precisely and maintain the integrity of the hydraulic system.

Parker Hannifin Pumps: One part number in our product line supports Parker Hannifin pumps. This seal is made to OEM specifications, delivering the same reliability and performance as our Permco-compatible seals.
