Pioneer standard centrifugal pumps provide superior performance in a variety of applications. The large impeller eyes deliver lower NPSHr and improved vapor-handling capabilities, making them ideal for industrial, municipal, agricultural, mining, paper mills, and oil and gas applications.

• 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.
• Be environmentally responsible — Our standard centrifugal pumps are environmentally responsible, too, with standard tungsten vs. silicon carbide mechanical seals that prevent pump leakage.

Vacuum Prime Assist Pumps

• 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

ES, P and PE Series

Pioneer self-priming pumps are designed for reliable solids and clear liquids handling. After initial priming, they continue to reprime automatically.

• 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.
