UltraSlim Micropumps

UltraSlim Disc Pump

Our UltraSlim Series responds to the growing demand for more compact pump solutions. This advanced design has a thickness of just 5.8 mm—a reduction of 50% over previous models—and an integrated filter, further reducing the space required to integrate UltraSlim pumps within end products. In common with all Disc Pumps, UltraSlim pumps combine silent operation, pulsation-free flow, millisecond response and high precision in a compact form factor.

LEE Ventus is actively developing higher performance pump designs. Contact us to discuss whether we have an alternative design that meets your requirements.


Mounting Guidance
Product is designed for axial seal on discharge port; product is not intended for direct connection to tubing. If using mounting eyes on pump body, LEE Ventus recommends using four compliant o-rings (e.g. 1.42 ID x 1.78 CS Nitrile 70 Shore A) with two o-rings per mounting eye (one above and one below the eye), Nylon M2 bolt and threaded mounting stud (e.g. Wurth Elektronik 9774050243R). This mounting scheme isolates high-frequency vibration and prevents audible noise. Note that metal bolts are not recommended for this reason.
