Heat metering system PVA-1GPU

process

The PVA-1GPU one-gallon hydraulic metering pump is ideal for dispensing highly abrasive, highly viscous pastes and compounds packaged in one-gallon metal pails. The PVA-1GPU extrudes material from the pail rather than pumping it like a typical reciprocating pump. The extrusion process minimizes shear and maintains material integrity. The PVA-1GPU operates as a hydraulic press. Material is extruded from the pail as a hydraulic intensifier pump forces a ram and follower plate into the container. An opening in the center of the follower plate allows material to flow out of the pump and into high-pressure material lines to be dispensed. The PVA-1GPU has many integrated features including: Hydraulic RAM pump with follower plate Virtually pulseless flow resulting in consistent bead diameter Only one moving pump component provides virtually maintenance-free operation Low shear resulting in a homogeneous material supply Hydraulic process eliminates the possibility of pump cavitation Fully pneumatic operation Thermal Interface Materials A thermal interface material ("TIM") fills gaps between mating surfaces with a substance that improves thermal conductivity beyond the air that would have otherwise filled that gap. The TIM acts as a conductive bridge that greatly improves heat transfer between between a heat-generating device (e.g. an integrated circuit) and a heat-dissipating device (e.g. a heat sink).
