Small pumps provide long-term reliability
A
Lee Products product story
Edited by the Engineeringtalk editorial team
Feb 29, 2008
Thanks to the use of chemically inert construction materials, Lee pumps are maintenance-free, providing users with a reliable operating life of at least 5,000,000 cycles.
Lee Products has released a range of miniature dispense pumps which are designed to meet the increasing demand for machine components which need to be smaller, yet capable of providing a precise, repeatable and reliable performance.
The pumps are available in three types, high and standard performance LPV models, along with LPL solenoid pumps, in a range of full-stroke volumes from 50 to 3000 microlitres.
These pumps, which are a suitable alternative to conventional syringe or peristaltic pumps, combine a compact, lightweight design, with low power consumption so they can be located wherever fluidic requirements dictate, regardless of maintenance accessibility.
They are designed for consistent, repeatable performance, with a CV as low as 0.04% at full stroke, volume resolution as small as 0.04 microlitres.
Thanks to the use of chemically inert construction materials, Lee pumps are maintenance-free, providing users with a reliable operating life of at least 5,000,000 cycles.
The range provides engineers with optimum flexibility as the high-performance LPV models combine speed, size and accuracy with small dispense volumes from 0.04 up to 1.0 microlitre and pressures to 6.5ba.
The standard LPV models offer the same reliable, repeatable performance on a smaller scale, with dispense volumes from 0.01 up to 1.5 microlitres and pressures to 1bar, while the LPL solenoid models enable consistent, fixed volume dispensing from 50 to 130 microlitres (depending on configuration).
Lee pumps are suitable for a wide range of automated liquid handling applications such as systems for in-vitro diagnostics, scientific instrumentation, drug discovery, or wherever high-precision, reliable fluids transfer is needed, on a miniature scale.
