XS-6S PUMP
6-Inch Self-Priming Pump for Wastewater and Slurries
The XS-6S is built for demanding liquid-handling applications where above-grade installation, reliable self-priming, and straightforward service access are important.
Its large-volume design supports automatic repriming in a completely open system without requiring suction or discharge check valves.
XS-6S Pump Summary
The XS-6S uses a two-vane, semi-open impeller designed for solids-laden liquids and slurries.
Pump-out vanes on the impeller shroud help reduce foreign-material buildup behind the impeller and reduce pressure on the seal and bearings, supporting reliable operation and easier maintenance.
The XS-6S also features a four-point external shimless adjustment at the clean-out cover for setting impeller-to-wear-plate clearance.
XS-6S: Designed for Easier Maintenance
The XS-S Series is designed to make routine service and wear-component adjustment more accessible without unnecessary pump disassembly.
