Miniature stepper dispense pump

Lee Products has introduced a miniature, chemically inert stepper dispense pump designed to deliver micro-litre volumes in the 50µL to 250µL range.

The LPD Series pump has been developed to offer design flexibility and cost-savings to the medical and scientific industries as a result of its maintenance-free design. It is said it can be located wherever fluidic requirements dictate, regardless of maintenance accessibility.

The pump is offered in both standard and high performance models, with the latter incorporating a home sensor, encoder and backlash compensation for more demanding applications and provides a CV of = 0.01% at total volume. The standard performance model is available with a home sensor for most other applications. Discharge pressures are 60psi maximum.

The LPD Series pump can be customised to meet the requirements of OEM applications and, Lee Products claim, offers a long-life performance of two million cycles for the standard model and five million cycles for the high performance option.
