Figure 3 Cooling Water Piping Harness
The partly water-cooled slinger seal version has 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.
Water Cooled End
Plate Option
Units having water cooled end plates can be identified by the
connecting hose which runs from the top of the drive end plate to the
bottom of the rear end plate. See Figure 4.
Units that will operate with continuous discharge gas temperatures of
250° F (121° C) or more must be connected to a water (liquid) supply
in order to maintain reasonable oil temperatures. Generally a water
flow of ½ to 1 GPM (1.9 - 3.8 L/min) is sufficient to maintain oil
temperatures below 150° F (65° C).
WARNING:
If unit is to be located outside or in a building where
