ABSTRACT:
A viscous material evacuator has a chamber to hold containers shaped as drums and has a plunger that presses into the interior of the drum to press out its highly viscous contents. The chamber has a hinged enclosure that has a hydraulically activated clamp that connects the two sides of the hinged enclosure. The hydraulically activated clamp can be arranged in series and also has a relief cartridge and pressure sensor to prevent the drum from becoming overpressurized.
