TriRotor Inc

TriRotor Inc has been manufacturing positive displacement rotary piston pumps for over 85 years, ever since we invented the shuttle block rotary piston pump. We have made many improvements to our pumps over the years, but we have always designed them to be completely interchangeable with our original pumps. As a result, we can replace or retrofit even the oldest pumps from in-stock parts or with minor modifications. Pump records, by serial number, are on file from as far back as the 1930s. Long Life Tri-Rotor pumps have an exceptionally long service life. They are simply designed, with only three moving parts. They feature an extra-long bronze shaft bearing and an oversize packing gland. Their operation is practically noiseless, and they have a minimum of maintenance requirements. With five pump series, Tri-Rotor has a pump for every application. These include models with variable control heads, bypass heads and solid heads. Pumps can be manufactured from stock for immediate shipment. Pump flow rates range from 30 GPM, for foot mounted and close coupled units, up to 220 GPM. Our pumps excel in pumping both common materials and difficult-to-handle products, with a wide range of viscosities, in industrial applications. They can handle everything from gasoline and oils to molasses and shortening to coolants and solvents. They will not chew, aerate or foam the material pumped. Tri-Rotor&#39s line of rotary piston pumps is complemented by a full selection of drives/components and mountings. With these, we can configure complex installations to meet exacting customer requirements. We also offer several time-tested standard configurations. Finally, Tri-Rotor can also supply portable units, silent chain drives, dual proportioning assemblies, multiple pump configurations, remote control metering, batch metering and infinitely variable control of constituent flows.
