How we dispense it
We have run SE4485 thermal compound on Dispense Robotics equipment. Our recommendation is PCPBM-150HF, fed from a 330 cc cartridge. Pump size still depends on your shot or bead size and cycle time, so send us those and we'll confirm.
- Abrasion: the ceramic filler that carries the heat wears pumps out. We use tungsten carbide rotors and wear-resistant stators and run the pump slowly, at 8 to 12 rpm, for long wear life.
- Feed: thick pastes don't flow to a pump on their own. Above cartridge volumes, a follower plate pushes the material out of the pail and keeps air out.
See our PCP progressive cavity pumps, or use the pump configurator.
Frequently asked questions
What pump should I use to dispense SE4485 thermal compound?
We have run SE4485 thermal compound on Dispense Robotics equipment. Pump size depends on your shot or bead size and cycle time; send us those and we will size it.
Can SE4485 thermal compound be fed from pails instead of cartridges?
Cartridges suit lab and low volume. Above that, a follower-plate pail pump feeds the metering pump directly, which cuts container changes and waste.
Does SE4485 thermal compound need mixing?
No. It is a single-component material, so there is no mixer and no ratio to hold. The job is accurate, repeatable volumetric metering, which is what a progressive cavity pump does.
Will SE4485 thermal compound wear out the pump?
Thermally conductive fillers are abrasive. With tungsten carbide rotors, wear-resistant stators and pump speeds of 8 to 12 rpm, stators typically last 6 to 12 months and rotors up to 24 months, and a pump rebuild takes under an hour.
