M03 Series (US) / G03 Series (Metric)

Diaphragm Pump Features

Versatile, Reliable Pumps for a Wide Range of Applications

  • Pumps the full spectrum of low-to-high viscosity fluids.
  • Features a seal-less design and horizontal disk check valves that enable the pump to handle abrasives and particulates that might damage or destroy other types of pumps.
  • Simple, compact design reduces initial investment and lowers maintenance costs.
  • Operational efficiencies reduce energy costs.
  • Able to run dry without damage (or additional maintenance) to the pump in case of accident or operator error.
  • Tolerates non-ideal operating conditions.
  • Minimizes maintenance and downtime because there are no seals, packing or cups to leak or replace.
