Pumps

With the recent acquisition of TTP Ventus, we are pleased to add piezoelectric disc pumps to our portfolio of miniature, precision pumps. These ultrasonic, pneumatic micropumps generate pressure or vacuum in a small, silent, vibration-free form factor, and are available with or without integrated electronics for added simplicity. Designed for highly accurate, ultra-smooth, gas and liquid flow control, our disc pumps deliver unrivalled pneumatic performance and enable innovation wherever precision control of small volumes is critical. Available in five different product series, these innovative pumps can achieve flow rates up to 2 LPM and pressures spanning from -400 to +600 mbar.

Variable volume dispense pumps are stepper motor-driven pumps providing full dispense volumes ranging from 50 to 3000 µL. Lee variable volume pumps use a unique drivetrain design to aspirate a volume of fluid accurately and then dispense that fluid volume out in smaller increments. These pumps are available in a single seal or dual seal configuration for improved sealing performance when flowing aggressive fluids. Each pump is equipped with a home sensor to establish the end of stroke position. In some models, an optical motor encoder is included for applications requiring feedback on piston movement.
