Small Capacity Pumps
A very broad range of small capacity pumps are manufactured by Smith for flow rates between 5 to 15 gallons per minute. All flow rates depend on the motor drive speed which is determined largely by the duty cycle. Pumps for intermittent duty can be driven at the maximum rated shaft speed while those for continuous duty or long on-times can be driven at slower motor speeds.
All Smith small capacity pumps are equipped with an internal bypass relief valve. The internal bypass relief valve used for the E-series pumps can also be used to direct flow back to the supply tank.
Pumps such as the E-series, D-series, and MC-1/GC-1 series are generally recommended for LP-GAS transfer. Please Download Catalogue CP-3.
Pumps such as the SQ-series are generally recommended for other liquefied gases and liquids. Please Download Catalogue CP-1A.
