Oscillating piston pump Helix

for gasairwith brushless DC motor

Short description
Helix miniature rocking-piston single-head pump for gas and air handling. Delivers up to 5 L/min free flow and supports pressures up to 100 PSIg (6.9 bar). Designed for pneumatic actuation and microfluidic systems.

Overview
The Helix miniature piston pump uses a rocking-piston mechanism in a compact single-head design. It integrates a brushless DC motor for reliable operation, low-noise performance (~45 dBA) and a lightweight PPS body suitable for space-constrained precision fluidics applications.
