    Abstract: A system for dispensing abrasive materials includes a transfer pump configured to pump abrasive material to a metering pump configured to pump the abrasive material to an application. Dynamic interfaces within the pumps are at least partially formed by sleeved components of the pump interfacing with a seal configured to engage with the sleeved surface during relative movement between the sleeved surface and the seal. The smooth exterior surfaces of the sleeves interface with the seals to prevent abrasive particulate in the material from adhering to the sleeve, preventing the abrasive particulate from being pulled between the sleeve and the seal.

    Abstract: A nozzle assembly includes a mixing channel and an aerator. The mixing channel has upstream and downstream ends defining a flow direction through the mixing channel and includes a housing wall and a mixer. The housing wall defines a flow passage and includes an inlet portion and a tip orifice. The inlet portion disposed at the upstream end and configured to receive a first material and a second material. The tip orifice is disposed at the downstream end and is configured to emit a plural component material from the mixing channel. The mixer is disposed within the mixing channel and is configured to mix the first material and the second material into the plural component material. The aerator is configured to flow nucleation air to a location downstream of an upstream end of the mixer and into a flow of the plural component material.

    Abstract: Systems and methods of dispensing a hot melt adhesive material that can be heated from a lower temperature flowable non-molten liquid state to a higher temperature molten liquid state, the systems and methods comprise: pumping with a pump the hot melt adhesive material in the lower temperature flowable non-molten liquid state into a supply conduit; passing the hot melt adhesive material through a heated thermal break in the supply conduit that allows free flowing movement of transitional non-molten and molten state material; heating the hot melt adhesive material in a heat exchanger connected to the heated thermal break to the higher temperature molten liquid state; and dispensing the hot melt adhesive material in the higher temperature molten liquid state from a dispenser in fluid communication with the heat exchanger.
