The partly water-cooled versions (92/93) have cooling
water to the seal adapter housing only. The cooling
coils and interconnecting water line are omitted and
the interconnecting line leading from the seal adapter
housing is led to the drain.
The air-cooled configuration requires no cooling water.
However, cooling water can be circulated through the seal
adapter housing on most models without modification to
the booster. Cooling the bearing housing will prolong the
life of the mechanical seal therein.
An on-off valve should be provided on the incoming line
and a regulating valve located in the drain line. The drain
line should terminate at an open drain to enable the
operator to better regulate the water flow.
HAZARDS ASSOCIATED WITH HAZARDOUS PROCESS FLUIDS
DANGER
It shall be the responsibility of the installer to ensure that piping is adequate,
sealing between pipe joints is adequate for the process fluids and proper
process and pressure protection devices are in place. It is also the
responsibility of the installer to assure that process gasses are not vented
in a manner that would be hazardous.
Refer to the manufacturer of the process media to assure that proper safety
precautions are in place.
5.4.1 BLOCKAGE OR RESTRICTION
WARNING
Damage to the booster could occur if there is blockage in the inlet or outlet
ports or piping. Care should be taken when installing the booster to assure
that there are no foreign objects or restrictions in the ports or piping.
5.5 WATER COOLING INSTRUCTIONS
WARNING
If the unit is to be located outside or in a building where ambient
temperatures can fall below freezing, then care must be taken to ensure
the water or liquid used for cooling does not freeze and damage the
booster. Cooling coils must be drained of liquid during downtime unless a
recirculating unit using a glycol mixture has been installed.
NOTE
Units are never shipped from the manufacturer with liquid in the end plates.
