Thelco Pump of the Day: Worthington 4LLR-11 Horizontal Split-Case Pump
Today’s Thelco Pump of the Day features a Worthington 4LLR-11 horizontal split-case pump with standard fitted construction, an 11.00-inch full diameter impeller, and clockwise rotation.
The Worthington LLR Series features a two-stage centrifugal pump design that continues to support demanding pumping applications. Furthermore, Thelco manufactures new Worthington Pumps and stocks thousands of Worthington Pump Parts to support customers maintaining these established designs.
Worthington 4LLR-11 Pump Specifications
Today’s featured Worthington 4LLR-11 includes the following specifications:
- Model: Worthington 4LLR-11
- Pump type: Two-stage horizontal split-case centrifugal pump
- Construction: Standard fitted
- Impeller diameter: 11.00 inches
- Impeller configuration: Full diameter
- Rotation: Clockwise
First, the 4LLR-11 features a horizontal split case design that provides access to internal pump components. Additionally, its two-stage configuration allows the pump to develop higher discharge pressure than a comparable single-stage design under appropriate operating conditions.
Most importantly, today’s pump features the specified 11.00-inch full diameter impeller configuration.
Worthington LLR Series Two-Stage Design
The Worthington LLR Series uses a two-stage centrifugal design within a horizontal split case casing.
Unlike single stage pumps, a two-stage pump moves liquid through two impeller stages. Each stage contributes to the total developed head.
As a result, the LLR Series provides an established solution for applications that require higher head capabilities.
Furthermore, the horizontal split-case construction allows maintenance personnel to access internal components by removing the upper casing section.
This design simplifies many inspection and maintenance procedures. Additionally, it helps customers maintain existing installations without replacing the entire pumping system.
Thelco continues to manufacture Worthington LLR pumps because customers still rely on these proven configurations.
11.00-Inch Full-Diameter Impeller
One of the key specifications on today’s Worthington 4LLR-11 is its 11.00-inch full diameter impeller configuration.
Impeller diameter directly influences centrifugal pump performance. In particular, diameter affects the head and flow characteristics at a given operating speed.
For this pump, the specified impeller diameter is 11.00 inches at full diameter.
Therefore, customers should verify the required impeller dimensions when ordering a complete replacement pump or individual Worthington Pump Parts.
Additionally, matching the correct impeller configuration helps maintain the intended operating characteristics of the existing installation.
Thelco manufactures replacement impellers and other components to the required specifications.
Clockwise Rotation Worthington 4LLR-11
Today’s Worthington 4LLR-11 features clockwise rotation.
Rotation is an important specification when replacing an existing centrifugal pump. Consequently, customers should confirm the correct direction before ordering.
Additionally, the viewing direction must remain consistent when identifying clockwise or counterclockwise rotation.
Thelco helps customers identify the appropriate pump configuration using model information, existing equipment details, and technical documentation.
By confirming these specifications early, customers can avoid unnecessary installation complications.
Standard Fitted Worthington LLR Pump
This Worthington 4LLR-11 features standard fitted construction.
Material configuration plays an important role in centrifugal pump selection. Therefore, customers should verify that the specified materials match their fluid and operating requirements.
Thelco supports multiple Worthington pump configurations, depending on the model and application.
Furthermore, our manufacturing capabilities allow us to produce new replacement components using established technical drawings and castings.
As a result, customers can maintain existing Worthington equipment with newly manufactured pumps and replacement parts.

Worthington LR and LLR Horizontal Split-Case Pumps
Thelco continues to support both Worthington LR and LLR horizontal split case centrifugal pumps.
The LR Series features a single-stage design, while the LLR Series uses a two-stage configuration.
Although these pump families serve different hydraulic requirements, both remain important to customers maintaining existing Worthington equipment.
Additionally, Thelco supports Worthington D500, D800, and D1000 Series centrifugal pumps, CNG pumps, and Worthington gear pumps.
Because many of these pumps have operated for decades, continued access to complete replacement pumps and individual components remains essential.
For this reason, Thelco maintains an extensive inventory of Worthington Pump Parts while continuing to manufacture new Worthington Pumps.
