Overview
The DV-7000 Series and DV-8000 Series Heli-Flow Pumps are rotary, positive displacement auger valves.
Each valve has a closed-loop, servo-controlled motor with encoder feedback that can reverse to create a
clean fluid cutoff. The DV-7000/DV-8000 pumps are designed and exclusively manufactured by Asymtek to
meet high-volume production requirements.
" NOTE The terms pump and valve are synonymous in this manual.
DV-7000
The DV-7000 (Figure 1-1) can be used as a floating head pump for dispensing dots, or as a standard pump
for dispensing lines and/or patterns. The DV-7000 is available in a luer- or footed-needle design with
interchangeable cartridges, allowing the pump to work with several different fluid types. The DV-7000 has a
hardened auger for use with filled epoxy materials and features a high flow rate.
