Keeping the seal cool is important in a hot oil pump
The hot pump is ideal for use in small spaces because it does not use a long (Lovejoy type) coupling. The pump is designed with a heat sync-type bracket, such that the mechanical seal environment is protected from the heat of the process. This design eliminates the need for external cooling to the seal. The cooling is accomplished with the air around the pump. Most other manufacturers utilize a water cooling system.
Keeping the seal cool is important in a hot Oil pump. The diagram below shows how the process temperature is reduced to less than 350 Degrees F as it passes through the bracket assembly to the area of the seal.Because of this design, a less expensive mechanical seal can be used. This keeps the cost of the equipment and the complications of keeping the seal cool down.
The small amount of liquid needed to lubricate the seal then arrives at the seal at a temperature that can be handled by the seal. A cooler seal means a reduced chance of oil distillation and oxidation.This extends seal life.
