Civil Engineering Cylinders, Actuators, and Hydraulic Systems

Engineered for Safety, Longevity, and to Survive Abuse

Passion Engineering understands infrastructure hydraulics. Hydraulic cylinders, power units, and electrohydraulic actuators must provide long service lives and be easy to inspect and maintain.

Our conservative design philosophy, use of high grade materials, and exceptional documentation align with the expectations of infrastructure contractors, owners, and operators alike.

  • Civil engineering cylinders for submerged, splash zone, and exposed fresh, brackish, and saltwater environments
  • Corrosion and wear resistant stainless steel, cobalt, nickel, and other specialty alloy rod cladding systems
  • Compliance with owner, municipal code, USACE, ASME, ASTM, AWS, and other organization requirements
  • Oversized corrosion resistant bearings
  • Designs for environmentally sensitive applications
  • Integral end-of- stroke proximity switches and position, pressure, and force transducers
  • Corrosion resisting gimbal, spherical rod end, and trunnions
  • Low friction and redundant seal systems
  • Long stroke cylinders with elastic stabilities in compliance with ISO/TS 13725:2016
