Weir Self-Primer with a range of benefits

The WSP offers end users a range of benefits over other self priming pumps in the Australian market. These benefits result in lower operating costs, higher actual efficiency and a longer life.

Easy Maintenance - Shimless / tool-less clearance adjustment
Unlike other self-priming pumps, that require up to 20 parts and 2 tools to adjust the clearance, no tools are required to adjust the WSP clearance. The only tools you need are the ones you were born with - your hands! This results in easier, faster maintenance.

Superior Materials - Hi chrome and ductile iron components
The WSP is manufactured with superior materials, in terms of both brinnel hardness and the grade of the materials, compared with materials used by competitors.

Enhanced Safety Features - Failsafe fill port assembly
The design of the fill port assembly ensures that it is impossible for the clamp bar to rotate (releasing the fill cap) until the pressure has abated, due to the way the bolt head fits into the recess. This is in comparison to competitor designs that require precise alignment of a square headed bolt to prevent the clamp bar from coming off the pump with high head velocity during disassembly. This ensures that solids stay where they should - in the pump, not out!

Complete Interchangeability - Pumps and spare parts
The WSP pumps and spare parts are completely interchangeable with Gresco, Pioneer
