Tuthill Products

The Industry Standard for external and internal gear pumps

For almost 100 years, the Tuthill Pump name has set the industry standard for Internal Gear Pumps and Magnetically Coupled Pumps. Tuthill Pump is known for engineering design and expertise providing reliable pump solutions in the most difficult applications.


Tuthill Pumps is now Ingersoll Rand® Pumps 

While the name on the products will change, the people, products and service behind our pumps will not – they will only become stronger with the added support of Ingersoll Rand. Learn more

Tuthill Pump Internal Gear Pumps can handle a wide variety of viscosities. GlobalGear® Internal Gear Pumps are capable of tackling the toughest, high viscosity fluid applications. Internal Gear Pumps are popular because they have only two moving parts and are easy to maintain.

The Tuthill Pump LubeTech Series have set the industry standard for lubrication and circulation applications. This family of internal gear pumps have been engineered to satisfy customers’ ever-changing requirements throughout a wide range of applications. 

Tuthill Pumps rely on their robust design and strong, durable materials to perform reliably in the most difficult applications in a variety of industries:

  • Adhesives and Sealants
  • Oil & Gas
  • Resins, Paints and Coatings
  • Energy & Power
  • Food and Beverage
  • Pulp, Paper and Packaging materials
  • OEM equipment (lubrication, circulation, cooling, dispensing/dosing)

How Do Tuthill Pump Internal Gear Pumps Work?

An Internal Gear Pump is a simply designed positive displacement pump with two rotating components. The larger gear is called the rotor gear. The smaller, inner gear is called the idler gear. Fluid enters the suction port and moves through the pump using the “gear-within-a-gear” principle.

As the rotor head and idler gear rotate, fluid starts to flood the pump head. The gear teeth create consistent volume pockets of fluids to provide a controlled amount of fluid discharge. The gears also create a low-pressure vacuum effect to push fluid out of the discharge side port.

LubeTech Internal Gear Pumps feature a unique reversing feature design. This design is ideal for rotating equipment and power transmission where direction of flow must remain consistent, even when shaft rotation changes.
