Multiquip 1803521221 Liner Ring - OEM Replacement Part for High Pressure Centrifugal Pumps

The liner ring is a critical wear component in high-pressure centrifugal pumps that maintains proper clearance between the impeller and volute housing, ensuring optimal pump performance and preventing efficiency loss. This genuine OEM liner ring is designed specifically for Multiquip's 205S series high-pressure pumps, which operate at maximum pressures up to 100 psi and heads up to 246 feet.

As outlined in Multiquip service documentation, impeller and volute binding issues can cause the pump to be hard to start or fail to operate properly. The troubleshooting procedures specifically reference adjusting clearance by removing shims from behind the impeller when binding occurs. Regular inspection and replacement of the liner ring prevents impeller/volute wear that leads to reduced pumping capacity and performance degradation. When your QP205SH pump shows signs of decreased flow rate (normal maximum is 106 gallons per minute) or difficulty starting, worn liner rings are a common cause.

This liner ring is compatible with the following Multiquip pump models:

• QP205SH High Pressure Centrifugal Pump
