Fixed Volume Precision Dispense Pumps

The Lee Company’s Fixed Volume Dispense Pumps offered by DenisDePloeg are solenoid-driven positive displacement pumps offering unparalleled reliability and performance. Featuring a compact chemically inert, self-priming design, Lee pumps deliver accurate and repeatable volumes of fluid.

Lee fixed volume pumps are optimized to provide design flexibility and considerable cost savings. Requiring 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. The combination port construction provides flexible options for the pumps to be used with soft tubing or mounted directly on a manifold.

Each pump is 100% functionally tested for performance and designed using materials that ensure consistent long-term performance. Our pumps have been qualified to operate across millions of cycles while maintaining accuracy and precision. Performance characteristics, including dispense volume, can be optimized to meet specific application requirements.
