DV-8000
The DV-8000 Heli-Flow® pump (Figure 1-2) features interchangeable cartridges for use in high flow rate
encapsulation and lid seal applications, allowing each pump to work with several different fluid types. The
DV-8000 has a fixed head design for use with high-viscosity fluids and high flow rate for fast dam writing.
Typical applications for the DV-8000 include thermal grease, silver epoxy, and lid seal and dam materials.

Dimensions
Length: 190-192 mm (7.48 - 7.56 inch)
Width:
33 mm (1.3 inch)
Depth: 72.6 mm (2.86 inch)
Air Pressure
34-552 kPA (5-80 psi, 0.7 - 5.5 bar)
Depending on the fluid, higher viscosities require higher pressures
Motor
Closed-loop control with encoder feedback on the dispensing platform
Flow Rate
Range
Flow rate depends on fluid, needle, valve speed, and syringe pressure
Minimum volume displacement allows pump to dispense dots smaller than 0.5 mm in
diameter
Maximum flow rate capability for damming material is well over 100 mg/s (viscosity 1 M
centipoises, specific gravity 1.76)
