Pumps for Light Industrial Applications

Fixed and Variable Volume Dispense Pumps for Light Industrial Applications

Lee pumps are engineered to provide maximum reliability for positive fluid displacement in light industrial applications. Featuring incredible control for aspirating and dispensing precise volumes of fluid, our maintenance-free designs deliver dependable solutions that enable you to minimize downtime and position the pump where the system’s fluidics dictate, regardless of accessibility. The adaptable nature of our designs simplifies the task of integrating pumps with other fluid control products to provide flexible pumping options without compromising performance or reliability.

Fixed Volume Dispense Pumps

Fixed volume dispense pumps are solenoid-driven, chemically inert positive displacement pumps, which provide accurate and repeatable dispense volumes ranging from 10 to 175 µL in a small, lightweight package. Available in dispense volumes ranging from 10 to 175 µL, Lee fixed volume pumps require a simple electrical signal for operation – the pumps aspirate fluid when energized and dispense fluid when de-energized. Integrated check valves, together with our unique housing design and diaphragm seal interface, prevent siphoning when the dispense point is positioned above the fluid reservoir.

Variable Volume Dispense Pumps

Variable volume dispense pumps are stepper motor-driven pumps providing full dispense volumes ranging from 50 to 3000 µL. Lee variable volume pumps use a unique drivetrain design to aspirate a volume of fluid accurately and then dispense that fluid volume out in smaller increments. These pumps are available in a single seal or dual seal configuration for improved sealing performance when flowing aggressive fluids. Each pump is equipped with a home sensor to establish the end of stroke position. In some models, an optical motor encoder is included for applications requiring feedback on piston movement.
