3.3.2 Double O-Ring Seal Flushing/Cooling
The flushing system may be arranged the same as the double mechanical seals, shown in figure 3.3.1 and 3.3.2. The double o-ring
seals may also be lubricated with grease if the pump application justifies doing so. In this case, the seal flush chambers are filled
through grease nipples with approved grease that is suitable for use with the pumped media. The chambers must be filled com -
pletely for proper operation. This can be accomplished by over pressurizing the chambers such that grease will be squeezed out
of the seals along the shafts and into the rotor housing. The amount of grease in the seal chambers must be monitored daily, and if
the pump is used in constant duty applications, it should be checked several times every 24 hour period.
