Viscous feeding technology
Sealing technology allows for pumping very thick (up to 15,000,000 CPs) or hot material with a metal-on-metal piston cartridge & does not work on fluid materials.
It includes a third check that scoops thick and viscous material into the foot valve. (primer checks)
Able to pump material with viscosity up to 2 million centipoises
Able to work up to 200°, like for bituminous adhesive,
for extreme conditions
