Seals for Fluid Power

Hydraulics, pneumatics and vacuum

Seals for Fluid Power, covering hydraulics, pneumatics and vacuum, ensure sealing in systems that transmit energy through hydraulic oil, compressed air and industrial vacuum. FP Modena supplies these with profiles interchangeable with international standards and technical support on pressure, speed and temperature.

Sealing solutions for fluid power systems

Hydraulic and pneumatic cylinders

Rod, piston, wiper, guide ring and guide band seals. A complete sealing system, with dynamic elements (rod and piston), static elements (O-rings on heads and end caps) and protective wipers.

Hydraulic pumps

O-rings for the static seats of covers and flanges, rotary shaft seals (oil seals) and backup rings for high-pressure zones in gear, piston and vane pumps.

Hydraulic directional control valves

O-rings and backup rings for the internal seats of the spools. Seals for the interface plates.

Rotary and semi-rotary actuators

Seals for the dynamic sealing between the chamber and the output shaft. Static O-rings for the covers.

Directional, proportional and safety valves

O-rings and anti-extrusion rings (backup rings) for the seats between the sections of the valve body. Ensure low friction and high fatigue resistance during frequent switching cycles.

Vacuum systems

O-rings in low gas-permeability materials, FKM/Viton® and FFKM, for flanges and fittings on industrial vacuum systems.

Typical operating pressures

Seals sized for pressures from vacuum up to 350-400 bar (standard hydraulics), over 700 bar (hydraulic presses and special applications) and 2 to 16 bar standard for pneumatics.
