The 227A Series™ internal gear pump is the ideal solution for soaps & surfactants, acids & caustics, and more because of its stainless steel construction for corrosion resistance over a wider pH range. It can handle flow rates up to 320 GPM (73 m³/h).
Features & Benefits
- All stainless steel construction, for corrosion resistance over a wider pH range
- Non-galling gear materials available for handling thin liquid applications
- Integral jacket chambers in the bracket and head surround the seal and pump internals to maintain a constant temperature, for rapid & efficient heating, or using steam, hot oil or water
