Multiquip 7207081300 Ring 3 Liner - OEM Replacement Part

The Ring 3 Liner is a critical wear component in Multiquip water pump assemblies that maintains proper clearance between the impeller and volute housing. This precision-machined ring ensures optimal pump performance by preventing efficiency loss caused by excessive internal clearance, which is a common cause of reduced water output and priming failures.

According to Multiquip service specifications, proper impeller-to-volute clearance must be maintained between 0.006" and 0.020" for correct pump operation. When this clearance exceeds maximum specifications due to liner wear, symptoms include difficulty priming, reduced flow rates, and extended pump-up times. The Ring 3 Liner works in conjunction with shimming adjustments to restore factory clearances and return the pump to optimal operating condition.

This liner is engineered to withstand the abrasive conditions common in construction and dewatering applications. Regular inspection of internal pump clearances during routine maintenance helps identify when liner replacement is necessary to prevent performance degradation.

Compatible with the following Multiquip water pump models:

• QP205SLT
• QP305SLT
