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.
