The Disc Pump is a revolutionary, ultrasonic, pneumatic piezoelectric micropump that generates pressure or vacuum in a small, silent, vibration-free form factor and delivers highly accurate, ultra-smooth flow control. The Ultra Slim (US) Series Disc Pump offers exceptional performance and efficiency along with a narrow, manifold mount profile and integrated hydrophobic filter. These pumps are ideal for applications in medical devices, life sciences, and environmental monitoring, including microfluidics, pipetting, wearable devices, and portable sensing technologies.

Note that Disc Pumps and valves must be purchased separately. This enables customers to select the exact model(s) that they wish to test. For help selecting the right model for your application, please speak to a Lee Sales Engineer.
These Getting Started Resources act as a primary resource for those starting out with the disc pumps. The resources include safety information, signposting to other resources, and guidance for running and controlling the disc pumps.
These Application Notes provide practical guidance on how our disc pumps can be used across a variety of applications.
This table below contains the part numbers and technical specifications for this product. If you have specific questions, need a quote, or would like to request a handbook or drawing, click the red request button in the column on the far right.
These Technical Guides provide non-application specific instructions and advice on the disc pumps.
Software includes PC-based interface and code snippets for running and controlling the disc pumps. The Electronics Reference Design package contains PCB and firmware reference designs together with supporting technical guides. This provides everything necessary for customers to design their own drive electronics.
The Smart Pump Module combines our piezoelectric disc pumps with drive electronics and pressure sensing in a tightly-integrated package.
These Application Notes provide practical guidance on how our disc pumps can be used across a variety of applications.

The Lee Company has developed the Lohm Laws for defining and measuring resistance to fluid flow. The Lohm is defined such that 1 Lohm will flow 100 GPM of water with a pressure drop of 25 psi at a temperature of 80°F.
Always verify flow calculations by experiment.
