Focus on Pumps

| By Gerald Ondrey

Dispense pumps meet the challenges of the market

The LPD Series of pumps (photo) are used in the medical market. The key features of the LPD Series are their size and ability to provide a long service life up to 10 million cycles. This enables users to design the LPD pumps into their systems without the need for periodic service. Unlike typical syringe pumps, which require periodic maintenance, LPD Series pumps are not only rated for millions of cycles, they are also maintenance-free. Therefore, they can be placed where the fluidic requirements dictate, regardless of accessibility. This also means that the pump can be situated near the fluid reservoir, so that tubing lengths and flow restrictions are reduced, which in turn provides faster aspiration rates, higher throughput and shorter test cycle times. — Lee Products Ltd., Gerrards Cross, U.K.
