OEM, and general industrial applications where a low cost
positive displacement pump in required. These self priming
pumps provide excellent pressure and suction lift capabilities
for pumping water and other clear, non-abrasive liquids.
Standard materials of construction are Bronze (B series) and
316 SS (A series). Use of a variable speed drive with the
ECO Rotary Pump would make an excellent metering pump.

• Self Priming — Will lift fluids up to 20 feet
• Bi-Directional Rotation — Allows flexibility in system design
• Available in Bronze & 316SS — Handles wide variety of fluids
