Series WMCH
Mag Drive Centrifugal

WMCP machined thermoplastic horizontal centrifugal seal-less mag-drive pumps (MCH Series) are fabricated from SOLID GLASS FREE Simona® PP or PVDF thermoplastics to resist internal or external corrosion. Heavy walled, CNC machined construction provide far greater resistance to permeation and migration of corrosive and permeating liquids. Additionally, added strength and thermal stability resists deformation, even in the most severe applications.


  • Exclusive SOLID GLASS FREE machined PP or PVDF casings and impellers components for maximum chemical resistance.
  • All plastic casing withstands external corrosion
  • Integral raised face flanges (no threaded adapters) to ensure zero leakage
  • Modular impeller allows for varying hydraulic performances
  • Oversized, high purity ceramic or silicon carbide thrust bearings and shaft
  • Standard, direct starting NEMA motors
