Water Cooling
1. A throttling needle valve should be installed on the inlet side of the water
cooling passages and adjusted so that the outlet water is between
120°F. and 160°F. Typically this means a flow rate of 2-5 GPM at 40°F
inlet temperature. Consult pump manufacturer’s specifications for
dimensions of water cooling connection.
2. The throttling valve on a water cooled pump is designed to automatically
give the proper flow rate for a 40 PSIG or greater supply.
3. If a minimum of 40 PSIG is not available, consult Fulton Thermal
Corporation about resizing the orifice. If the temperature of the cooling
water is greater than 55°F to begin with, a correspondingly greater flow
rate is required.
4. For automatic operation of water cooling, wire a solenoid valve on the
inlet to open whenever the pump motor starter is energized.
5. The outlet flow from the pump must not be restricted in any manner.
Therefore, valves are not to be installed on the outlet. Check local codes
regarding disposal of hot water.
