Summary of Tri-Rotor Pump
- The Tri-Rotor® pump is a positive displacement, rotary piston pump (also known as a “shuttle block” pump)
- Manufactured since 1932
- Unique design has 3 rotating internal components – a rotor, a piston, and a shuttle
- Available in cast iron and bronze materials Summary
- Flow rates up to 240 GPM
- Handles viscosities up to 1,000,000 cP (5,000,000 SSU)
- Known for its long life, Tri-Rotor® has a world-wide installed base in the hundreds of thousands of pumps
- Manufacturing headquarters are in a 12,000 sq. ft. plant in Torrington, Connecticut, USA (near Hartford, CT)
- Pump records, by serial number, on file back to the 1930s

History Of Tri-Rotor Pump
- 1930 Charles Waite of Somerville, MA files a patent application for a new concept of a rotary pump
- 1932 Yale & Towne Manufacturing Company of Stamford, Connecticut, obtains the rights on Waite’s patent and forms the “TriRotor” Pump Division
- 1947 Yale & Towne registers “Tri-Rotor” as a US trademark
Leo “Nick” Nikora
- 1958 Yale & Towne sells the pump division to Leo “Nick” Nikora, a successful businessman, who moves the operation to Torrington, Connecticut
- 1961 Tri-Rotor begins to globalize under Leo’s leadership, establishing distribution in Japan with Tominaga and Co. Ltd., an important partner to this day
- 1965 Tri-Rotor obtains a Japanese trademark
- 1968 Tri-Rotor and Tominaga open a plant in Tokyo to manufacture pumps for Southeast Asia regional customers
- 1976 Leo’s youngest son, Henry “Hank” Nikora, joins his father at Tri-Rotor and quickly becomes the technical resource for customers
- 2001 Hank Nikora acquires the company from his father and is still very active at TriRotor
- 2017 Tri-Rotor celebrates its 85th year of continuous operation

Tri-Rotor Pumping Principle
- The three moving parts of a Tri-Rotor pump are a rotor, a piston, and a shuttle. The rotor is a liquid-tight fit within the pump body, with the piston and shuttle being equally liquid-tight in their fit to each other and to the rotor. In operation, the piston slides back and forth in the rotor slot discharging from the opposite end. At the same time, the shuttle slides back and forth within the piston, drawing liquid through one rotor opening and discharging through the other. The rotor, which functions as a rotating valve, channels the liquid from the suction port around through the pump body and out the discharge port.
- This action, while rotary, actually accomplishes the same type of pumping principle as a direct-acting piston pump. There are, therefore, two direct-acting pistons pumping through two cylinders, with rotary action of the rotor acting as the valve.
- The reciprocating piston action is accomplished by the center bearing of the shuttle, which rotates on a shuttle pin eccentric to the rotor shaft. Since the rotor is concentric with the shaft and the shuttle bearing is eccentric to the shaft, a reciprocating action of the piston and shuttle within their respective cylinder slots is created by the revolving rotor. The combined overlapping strokes of the piston and shuttle for each revolution of the rotor create a relatively smooth discharge. An extremely high volumetric efficiency is obtained because of the piston-type action and the liquid-tight fit of the moving members.
- Highly viscous materials are easily handled with exceptionally high volumetric efficiency while thin, volatile materials are handled with little loss in slippage through the pumping members. Shear sensitive materials are handled with little or no mechanical beating, since the product is carried through the pump by gentle piston action without being subjected to agitation.
