Precision Dispensing Pump for UV Sensitive Fluids

Fluid Metering, Inc. of Syosset, NY announces their new VMP Electronic Variable Displacement Metering Pump for accurate dispensing of UV (Ultra-Violet) sensitive fluids.

Typical fluids that fall into this category are, UV curable adhesives, UV coatings, and photo lithography chemicals.

The VMP Variable Displacement Dispenser is a fully programmable dispensing system, which utilizes FMI’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.

The VMP can be programmed for a variety of functions using a user-friendly Touch Screen Interface (TSI) which can control up to 16 pumps on a single bus. Up to 128 metering devices can be controlled using a PLC or computer. The VMP will store up to 100 programs letting you change between setups on the fly.

For UV applications, the pump head is made from either 316 stainless steel or opaque PVDF to isolate UV light from the process fluid as it travels through the pump head.

Typical applications include dispensing of UV curable adhesives for medical component assembly, photo resist for printed circuit and semiconductor manufacturing, and UV adhesives & coatings for DVD manufacturing.
