Liquids and Temperatures 

Maximum fluid temperature is 180°F (82.2°C). Fluids must be compatible with silicone rubber seal elastomer. To promote long product life, assure that ambient air can circulate around the unit to prevent over-heating. Ground metal frame motors.


One of the outstanding features of this pump is its compact A.C. or D.C. motor size. The motors are ODP with an internal cooling fan and are UL listed and is rated for continuous duty. Rotation is clockwise from shaft. 50 Hz is permitted. There is a #6-32 tapped hole ground connection provided on the end of metal framed motors.

Suction Lift

Prevent air trapping in plumbing lines by avoiding loops. Use air vent fitting connection to purge air. Though capable of pulling slight vacuum, the pump performs best under flooded suction conditions when located for gravity feed.

An optional air vent fitting prevents loss of prime that can occur due to entrapped air. It is factory installed with a disposable vent cap. Entrapped air can be encountered in applications where the liquid in the supply tank is completely exhausted. Air can be introduced to the system before the next tank filling.

For best results, configure and install pump with air vent near the top.
