Product Description

The High Chrome Frame Plate Liner Insert, commonly referred to as the Back Liner, is a critical wear component engineered for high-performance slurry pumps. Positioned strategically behind the pump impeller, this insert works in tandem with the volute liner and throatbush to create a precision-engineered pump chamber, ensuring an optimized flow path for abrasive slurries.

Manufactured from premium high-chrome alloys, these frame plate liners are designed to withstand extreme erosion and abrasion in the most demanding industrial environments. By providing a robust protective barrier, they significantly extend the operational lifespan of the pump housing and maintain hydraulic efficiency under heavy-load conditions.

Frequently Asked Questions

Q: What is the main purpose of a Frame Plate Liner (Back Liner)?

The Back Liner is designed to protect the pump frame and housing from abrasive slurry. It forms a critical part of the pump chamber behind the impeller, preventing wear on the primary structural components of the pump.

Q: Why choose High Chrome material over standard alternatives?

High Chrome alloys provide exceptional hardness and resistance to abrasive wear. In slurry pump applications, this significantly extends the mean time between failures (MTBF) compared to standard cast iron or rubber.

Q: How do I determine the correct liner code for my pump model?

You can match your pump model (e.g., 6/4D-AH) with the corresponding liner code (e.g., D3041) using our compatibility chart. If you are unsure, please provide your pump's serial number to our technical team.

Q: Can these liners be used in dredging and mining applications?

Yes, they are specifically engineered for the most aggressive environments, including mineral processing, sand dredging, and wastewater treatment where high solids concentration is present.

Q: What signs indicate that the back liner needs replacement?

Typical signs include a drop in pump discharge pressure, increased vibration, or visible thinning of the liner during routine inspections. Regular monitoring is recommended to prevent housing damage.

Q: Do you provide OEM castings for custom pump specifications?

Yes, we specialize in OEM castings and can manufacture frame plate liners and other pump components based on your specific technical drawings and material requirements.
