406M Flexible Impeller Pumps

Enhanced Performance Features:
Our Close Coupled Rubber Impeller Pumps boast an efficient design, with the rubber impeller securely attached to a stainless steel motor shaft or mounted on a separate shaft for a snug fit over the motor shaft. Crafted from high-quality Neoprene rubber, our impellers ensure efficient performance, with Buna N options on hand for specialized applications. Each motor comes equipped with reliable ball or sleeve bearings, and select models boast a mechanical seal for superior protection.. 

Streamlined Drive Arrangement:
The pumps are designed for direct mounting onto electric motors, using a compatible bronze plate for seamless installation with Nema C flange motors. 

Fluid Compatibility and Temperature Range:
Our pumps are optimized for a variety of liquids, operating within a temperature range of 40°F to 140°F (4 - 60°C). They're not suitable for gasoline or solvents but can manage oil-contaminated water and kerosene with Buna N impellers. In freezing conditions, simply drain the pump and fill the chamber with antifreeze to protect it. 

Outstanding Suction Power:
Get started with ease, as our pumps require initial priming to prevent dry running. Achieve impressive suction lifts up to 15 feet (4.6 m) when the pump is fully primed. For the best performance, use a foot valve with a built-in strainer and keep suction lines as short as possible.
