In precision dispensing, even small pressure fluctuations can cause dispensing errors, especially with sensitive materials or long fluid lines. Common issues like pressure spikes, flow surges or unstable tank pressure often lead to inconsistent results.

The marco PushMembrane solves this by stabilizing the pressure between material supply and dispensing head. A controlled pneumatic-oil reservoir applies consistent force to the fluid via a flexible membrane. When the internal volume decreases, an inlet valve refills the membrane—without interrupting flow. This ensures the dispensing valve always operates under stable pressure, regardless of tank distance or upstream pressure behavior.

The PushMembrane is installed inline between the tank and valve, making it an effective upgrade for improving accuracy and repeatability in any advanced microdispensing setup.
