The vacuum pump casing and the front end plate
have an integrated cooling water jacket. The SDV
series pumps can be configured with two different
types of cooling systems: Fresh Water Cooling and
Circulating Cooling.
FRESH WATER COOLING
The fresh water cooling system consists of a
“once-through” cooling water circuit. To monitor
the adequacy of the cooling water flow and the
cooling water discharge temperature, install a flow
indicator, flow switch on the cooling water supply
line and a temperature gauge (or switch) at the
cooling water discharge line.
On SDV-120 pumps, the silencer is not jacketed.
Hence, the cooling water circuit is not extended to
the process exhaust silencer (
see Figure 3-1
).
