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.

Abstract: A communication system for an industrial process includes multiple slave modules connected in series with a master controller. The master controller stores a communication schedule that defines an ordered sequence of messages and identifiers associated with each message. The master controller transmits messages downstream through the slave modules to a terminal one of the slave modules. The terminal slave module generates a return message that is transmitted upstream to the master controller. Each slave module receives each downstream message, identifies based on the message identifier whether the message is associated with response information from the slave module, and inserts the response information into corresponding upstream messages.

Abstract: A lubricant pump (14) and a method thereof are disclosed. The lubricant pump (14) includes a pump base (32) and a reservoir housing (30). The pump base (32) and the reservoir housing (30) define a lubricant reservoir for storing lubricant. One or more pump elements (34) extend at least partially into the lubricant reservoir. Heaters (36) are disposed on the pump base (32) proximate the pump elements (34). The heaters (36) are configured to heat the local area surrounding the pump elements (34), to thereby reduce the viscosity of the lubricant at the pump elements (34). The heaters (36) are electrically connected to a thermal switch (38) to control activation and deactivation of the heaters (36). With the lubricant pump (14) and the method thereof, the thermal switch (38) can control the heater (36) based on air temperature rather than the temperature of the lubricant, so the viscosity of lubricant is well controlled.
