Abstract: A plural component dispensing system includes a first heated hose, a second heated hose, a controller, and a dispensing device. The first heated hose and the second heated hose include electrical wires that supply heat to the first and second heated hoses to heat fluid components within the first and second heated hoses. The first and second heated hoses are electrically coupled to the controller and are fluidly coupled to the dispensing device. The controller is configured to control and alternate the electrical power supplied to the first heated hose and the second heated hose to heat the first heated hose independent of the second heated hose.

Abstract: A pump system includes a housing, a lubricant system, and control circuitry. The housing includes a pump chamber defined by the housing and a throat seal. The lubricant system includes a lubricant pump, a lubricant gallery defined within the housing of the main pump, and a lubricant circuit fluidly connecting the lubricant pump and the lubricant gallery. The throat seal is disposed adjacent to and between the pump chamber and the lubricant gallery. The control circuitry is configured to cause the lubricant pump to pump a purge volume of lubricant through the lubricant system, cause the lubricant pump to stop pumping for a first time period after the lubricant pump has pumped the purge volume, and cause the lubricant pump to pump the purge volume of lubricant through the lubricant system after the first time period.
