Thelco Pump of the Day: Worthington 1.5GRM Flanged Gear Pump

Today’s Thelco Pump of the Day features a Worthington 1.5GRM flanged gear pump configured for counterclockwise rotation.

The Worthington GRM Series is a positive displacement gear pump design built for applications requiring dependable, consistent fluid transfer. Thelco continues to manufacture new Worthington Pumps and stock thousands of Worthington Pump Parts, including support for Worthington gear pump models that have been in service for decades.

Worthington 1.5GRM Flanged Pump

Today’s featured pump is a Worthington 1.5GRM with a flanged connection configuration and counterclockwise rotation.

Key specifications include:

  • Model: Worthington 1.5GRM
  • Pump type: Positive displacement gear pump
  • Connection: Flanged
  • Rotation: Counterclockwise
  • Configuration: Complete pump
  • Condition: New

The flanged design provides a secure piping connection, while the specified counterclockwise rotation ensures the pump is configured correctly for the intended installation.

Rotation is particularly important when replacing an existing Worthington gear pump. Confirming the correct rotation and connection configuration helps ensure the replacement matches the existing system.

Worthington GRM Gear Pump Design

Unlike the centrifugal pumps featured in many of our Pump of the Day posts, the Worthington 1.5GRM is a positive displacement gear pump.

Gear pumps move fluid through the controlled rotation of internal gears. As the gears rotate, fluid is carried through the pump from the inlet to the discharge side.

This operating principle makes gear pumps well suited for many fluid-transfer applications where controlled, consistent flow is required.

Additionally, the compact design of the GRM Series makes these pumps a practical replacement option for existing Worthington installations where maintaining the original pump configuration is important.

Counterclockwise Rotation

This particular Worthington 1.5GRM is configured for counterclockwise rotation.

Rotation should always be verified when specifying a replacement gear pump. The correct configuration depends on the existing installation, drive arrangement and required direction of flow.

Therefore, when customers contact Thelco for a replacement Worthington gear pump, providing the existing model information, rotation and connection style helps us identify the correct configuration.

For today’s pump, that means a 1.5GRM flanged pump with counterclockwise rotation.

Flanged Worthington Gear Pump

The flanged inlet and discharge connections are another important feature of this pump.

Worthington gear pumps can be found in different configurations, so connection type matters when replacing an existing unit. A properly matched flanged replacement can simplify installation by maintaining compatibility with the existing piping arrangement.

Thelco can help identify the appropriate pump based on the existing Worthington model and application requirements.

Worthington Gear Pumps and Replacement Parts

Thelco supports more than centrifugal Worthington Pumps. We also manufacture and supply Worthington gear pumps and stock replacement components for these established designs.

Our inventory of Worthington Pump Parts supports customers maintaining pumps already operating in the field. Depending on the model, this includes internal components, shafts, gears, bushings, gaskets and other replacement parts.

As a result, customers can contact Thelco for both complete replacement pumps and individual components rather than searching for obsolete equipment or adapting an unrelated pump to an existing system.

Keeping Worthington Pumps in Service

Many Worthington pumps currently operating in plants and facilities were installed years or even decades ago. However, replacing the entire system around an older pump is not always necessary.

Thelco continues to manufacture Worthington Pumps from established technical drawings and castings while maintaining an extensive inventory of Worthington Pump Parts.

That combination allows us to support customers who need a complete replacement pump, an individual component or help identifying an existing Worthington model.

Today’s Worthington 1.5GRM flanged gear pump with counterclockwise rotation is another example of the Worthington equipment Thelco continues to manufacture and support.
