Pioneer standard centrifugal pumps provide superior performance in a variety of high pressure, sewage, trash or dewatering applications. The large stainless-steel impeller eye yields lower NPSHr and improved vapor-handling capabilities, making them ideal for industrial, municipal, agricultural, mining, and oil and gas settings.

• Minimize maintenance costs — Replaceable wear rings, oversized bearings and shaft keep the pumps running optimally.
• Reduce overhead costs — The modular design helps keep your on-hand parts inventory low.
• Reduce operating costs — Our industry-leading, high-performance impeller design provides more flow with less horsepower for lower operating costs.

Pioneer Prime: Vacuum Prime Assist Pumps

All Pioneer standard centrifugal pumps can be upgraded to a Pioneer Prime vacuum-assisted self-priming pump that delivers extreme flows with high head capability and utilizes our advanced priming system. This dry prime system is capable of rapid (50 CFM) unattended priming and operation for the ultimate in reliable performance, even in run-dry situations and suction lift applications. The Pioneer Prime system combined with our low NPSHr impeller design achieves better suction lift and faster priming than the competition.

• Eliminate environmental concerns due to product spillage — Our PosiValve™ stainless steel priming valve is specifically designed to eliminate product carryover.
• Achieve better performance — Large impeller eye areas with lower NPSHr characteristics allow for higher suction lift capability.
• Use less energy — Optimized package design matches the vacuum prime assist pumps with engines to use less horsepower and achieve higher performance.
• Increase flexibility — Modular pumpset designs make it fast and easy to convert from trailer to skid.

Wet Prime Pumps

Pioneer self-priming pumps are designed for reliable solid and clear liquid handling. After initial priming, they continue to re-prime – for low maintenance and cost-effective performance.

• Rely on the best materials — Standard heavy-wall ductile iron volute and 17-4 PH stainless steel shaft for durability and peace of mind.
• Get peak performance — A simple external shimless impeller adjustment means the user can easily adjust the tolerance between the impeller and wearplate.
• Trust our seals — Cartridge type tungsten vs. silicon carbide mechanical seal makes for ease of maintenance and simple installation.

HWR Wear-Resistant Pumps

Pioneer Pump® HWR Series Wear-Resistant Pumps are manufactured with high-chrome white iron to maximize resistance against destructive abrasives and maintain peak performance longer in slurry and manure applications. Oversized shafts, bearings, and seals, in addition to thick casting walls further resist unnecessary wear, while an axial-style wear ring allows for external adjustment to simplify service and increase pumping uptime. The HWR Series is available in flows up to 4,875 gpm and can be packaged to meet nearly any application need.
