STF Positive Displacement Adjustable Dispensing
Versatile Pump Solution
The STF Positive Displacement Adjustable Dispensing Pump is offered in
drive configurations from 5 µL to 400 µL in 1 µL increments. Each drive
model when paired with a Fluid Metering pump head, guarantees optimal
dispense volume/flow rate and full chemical compatibility. Standard pump
head options are available with various sealing options and diameters to suit
specific requirements.

Customizations
• Accuracy is a percentage of the target dispense volume
Be it a small tweak to existing technology or a full
development project, our pumps and dispensers
can be customized to accommodate dispense
volume, flow rate, temperature, pressure, materials,
and more.
• Maximum standard operating pressure at 100 psig
• Fixed Link pumps are calibrated in-house to a set
volume
Regulatory Compliance
• Flow rate can be changed by adjusting motor speed
