American pump engineering heritage and Tuthill brand development

Established in 1892 by James B. Tuthill, the American manufacturing company Tuthill delivered fundamental contributions to positive displacement hydraulic machinery.

Designing a dependable internal gear pump for liquid fuel transfer and heavy lubricating oils, the factory established a versatile foundation for broad industrial fluid handling operations.

Across more than a century of engineering, Tuthill introduced innovative fluid technologies including automatic flow reversing mechanisms and sealless magnetic drive gear systems.

Today, the Tuthill industrial pump family operates within the Ingersoll Rand ARO fluid management program, retaining verified machining tolerances and long-term operating durability.

Design features and automatic flow reversal principle of the L Series

Tuthill L Series lubrication pumps are built around an internal gear principle containing only two moving elements: an externally toothed rotor and an eccentric idler gear.

A minimized count of friction pairs ensures elevated mechanical efficiency, low vibration levels, and extended service life when pumping lubricating fluids with viscosities up to 5000 SSU.

A primary technological advantage of RLA and RLE models is their mechanical reversing feature: upon direction changes of the drive shaft, an internal crescent guide automatically indexes 180 degrees.

This provides continuous one-way fluid discharge without requiring external bypass plumbing, non-return check valves, or motorized diverter spools.

General purpose C Series circulation pumps and CC close-coupled units

Engineered for continuous oil circulation inside gear drives, forced cooling of industrial roll stand bearings, and low-pressure hydraulic feed circuits, the C Series serves diverse processing duties.

Frame sizes from 1C through 6C deliver smooth fluid streams up to 84 gallons per minute at discharge pressures reaching 250 PSI.

The close-coupled CC variant attaches directly to the front face of NEMA or IEC electric motors without requiring intermediary mounting brackets or flexible shaft couplers.

This design compacts the total pump set footprint, avoids angular misalignment along joined shafts, and extends mechanical seal longevity during high-temperature operations.

Heavy-duty 4000 Series process pumps and 1000 Series viscous oil units

Moving heavy mineral oils, petroleum wax, and viscous lubricants demands strong resistance against fluid cavitation forces within internal channels.

Tuthill 4000 Series process pumps (models 4100 and 4120) and 1000 Series units are engineered specifically for circulation circuits operating with kinematic viscosities up to 1000 SSU.

Pump structural parts are machined from dense iron alloy grades, while shaft journals ride on radial sleeve bearings fabricated from tin bronze or carbon graphite.

An adjustable spring-loaded relief valve integrated into the pump head protects the electric motor and downstream pipeline valves against sudden pressure spikes.

Modular architecture of heavy-duty GlobalGear process pumps

Across chemical, paint, petroleum refining, and asphalt industries, process pumps operate with aggressive, abrasive, and hot viscous materials.

Tuthill GlobalGear positive displacement pumps are built for harsh operating conditions: enlarged shaft diameters and heavy-duty thrust bearings prevent rotor shaft deflection under heavy fluid drag.

A modular back pull-out construction allows routine inspection, mechanical seal renewal, and gear replacement without detaching the iron alloy pump housing from fixed plant piping.

Optional steam or electric heating jackets prevent resins, bitumen, and polymer adhesives from solidifying inside fluid chambers during production pauses.

Precision sealless pumps with magnetic drive coupling across D and T series

For high-precision chemical dosing, laser cooling fluid circulation, and laboratory analytical systems, Tuthill supplies miniature gear pumps of the D, T, and W Series.

Motor torque is transmitted to the external gear set through a sealed non-magnetic containment shell using permanent samarium-cobalt magnetic elements.

The total elimination of rotating shaft packings and mechanical face seals ensures complete fluid containment (Leak-Free / Seal-Less) without chemical leakage risks.

Fluid gears machined from PEEK polymer paired with precision ceramic bearings deliver chemical inertness and consistent low-flow volumetric accuracy.
