Fluid Metering, Inc.: The VMP Electronic Variable Displacement Metering Pump is designed for accurate dispensing of UV-sensitive fluids, including UV-curable adhesives, UV coatings and photo lithography chemicals. The dispenser is a fully programmable dispensing system, which utilizes the company’s patented CeramPump® valveless piston pump design. A precision stepper motor controls the pump speed. However, what makes the VMP truly unique from other FMI dispensers is the addition of a second stepper motor, which electronically adjusts the piston displacement. This provides ultra-fine dispense adjustments through varying of piston stroke length.
