Thermoplastic, WMRP, Self-Priming, Rotary Vane, Seal-Less, Mag-Drive PumpsMP Series-Machined Thermoplastic, In-Line :

WMRP machined thermoplastic self-priming rotary vane seal-less mag-drive pumps (MP Series) are positive displacement pumps intended for low-flow/high head applications, high-pressure systems or where metering is required. CNC machined from solid Simona polypropylene or polyvinylidene fluoride (PVDF), WMRP Machined In-Line pumps are extremely resistance to internal or external corrosion, permeation and migration of solvents and corrosive. WMRP Machined In-Line pumps can handle pressurized applications and are capable of dry starting. Zero-leakage operation ensures maximum safety and full compliance with toxic emissions regulations.


  • Self-Priming and can run dry without damage

  • No gears to wear or metal to metal contact, low internal slip

  • Capable of proportioning with variable speed drives, turn-down ratios depend upon differential head requirements

  • Replaceable carbon cartridge-low maintenanace costs

  • High torque magnets for direct starting motors

  • All non-metallic wetted components
