High-Viscosity Filter Cart System

High-Viscosity Filter Cart

Filter cart choices have been very limited when it came to filtering lubricants with viscosity of greater than 500 SUS @ 100ºF. The problem with attempting to filter a high viscosity oil with a lower viscosity system is that the pump and filters are not designed to work with higher pressures required to push high viscosity fluids through the system. As a result these low viscosity units operate primarily in “bypass” mode where little if any of the high-viscosity oil gets filtered.

That is where Trico’s High-Viscosity Filter Cart System comes in. This system is specifically designed for high-viscosity fluids associated mainly with gear oils and can filter oils up to 7500 SUS @ 100ºF (1600 cSt @ 40ºC).

To ensure that the equipment receives the cleanest oil possible, for increased equipment life, Trico’s High-Viscosity Filter Cart System provides two-stage filtration. The oil flows through the primary filter first, where coarse particulate is removed. Then the fluid flows through the secondary filter where fine particulate and water are removed.

A variety of filter media elements are available to meet recommended manufacturer cleanliness levels.


  • Bypass Valve – Allows transfer of oil without filtering.
  • Oil Sampling Ports – Two sampling ports available to monitor condition of oil.
  • Quad Filters – Four filter elements for increased holding capacity
  • Industrial Strength Tires – Wide tires capable of getting over large grate gaps.
  • Differential Pressure Gauges – Indicates when elements need to be changed.
  • Heavy Duty Cart – Rugged and built to last.
  • Hose & Wand Assembly – Heavy-duty hydraulic hoses with 3 ft long metal wands.
  • Drip Pan – Keeps work area safe and clean.
