Miniature, Chemically Inert Stepper Dispense Pump

A miniature, chemically inert Stepper Dispense Pump which is designed to deliver variable micro-litre volumes in the 50µL to 250µL range with a consistent performance yet in the most compact package, has been introduced by Lee Products.

The LPD Series pump has been developed to offer greater design flexibility and significant cost-savings to the medical and scientific industries as a result of its maintenance-free design. 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 60 psi maximum.

The LPD Series pump can be customised to meet specific application requirements of OEM applications and offers a long-life performance of 2 million cycles for the standard model and 5 million cycles for the high performance option.
