8.2 WATER COOLED PROCESS PUMPS

The centrifugal pumps used on oil temperature control units employ a water circuit to cool

the mechanical seal.

The exclusive hot oil pump has a “hidden” channel cavity molded into the casing. This

channel circumscribes the seal area. The channel is fed cooling water from the plant’s

supply source. As the unit pumps hot oil (up to 500°F) to process, the cooling circuit

serves to “protect” the seal by “spot” cooling the area immediately around the seal (see

photograph below).

As a safety precaution, a pressure switch is installed in the supply line to monitor the

water source. If the pressure falls below 10 psi, the switch cuts the control circuit and

the unit stops. Thus, the hot oil temperature controller can only operate when there is

adequate cooling supply water.

Normally, this temperature is well below 150°F, even when the unit is heating oil to 500°F.

The advantages to the water cooled hot oil pump are:

Lower shaft seal temperatures for longer seal life (less maintenance!)

Motor bearings run cooler for longer motor life (less maintenance!)
