Because of their unique design, Tri-Rotor pumps excel in pumping many difficult-to-handle products, as well as the common materials found in many industrial applications.  Tri-Rotor pumps, manufactured from cast iron or bronze, can serve all of the applications chemically compatible with these materials.  Some key markets, and applications of types of fluids pumped within those markets, are shown below.


Tri-Rotor pumps are an excellent choice for pumping many different types of oils of varying viscosities and at various temperatures.  The oils themselves provide excellent lubrication of the internal components of the pump.  These oils include:


Tri-Rotor has been very successful in applications within the food industry for decades.  Tri-Rotor pumps in this market are built with food grade seals and gaskets as standard.  All of the internal components undergo sanitary preparation and the pumps are offered with a lacquered white finish or stainless steel epoxy coating.  See Other Pump Options section for more details.  Our pumps have been very successful in such applications as:

Coatings & Sealants

Pumping coatings and sealants requires a gentle and smooth pumping action to preserve the quality of the product.  Tri-Rotor pumps are shear-sensitive and produce low pulsation while delivering accurate and consistent results.  Typical applications include:
  • Adhesives
  • Dyes
  • Inks
  • Lacquer
  • Paint
  • Silicone
  • Varnish


Fuels are easily handled with a Tri-Rotor rotary piston pump.  Care is to be taken with these low viscosity fluids as they have low boiling points.  Lift should be kept to a minimum.  Common fuels pumped by Tri-Rotor include:
  • Gasoline
  • Jet Fuels


Tri-Rotor pumps are ideal for chemical liquid transfer for those liquids compatible with cast iron material of construction.  These pumps can easily handle certain chemicals with varying levels of abrasiveness, corrosiveness, and viscosity.  A Tri-Rotor pump, equipped with the variable volume V-Head, is a metering pump, providing flow measurement and control for applications that require precise volumes of chemicals.  Common chemicals pumped include:
  • Liquid Soaps
  • Alcohol
  • Solvents
