* All GXS dry pumping systems have a valve cooling system which will cause the coolant ow rate to
vary in response to pump load condions. Table: Water consumpon data (GXS160/250/1750/2600)
states that the "minimum ow rate required" under worst
‑
case pump load condions when all valves
are open. Flow rates need to be increased and/or coolant temperatures reduced if Glycol or other
coolants are used dependent on the diluon type.
† The dierenal pressure values given are the minimum dierenal pressures required across the
water supply/return at the point of connecon to the pump to achieve the desired ow when the
solenoid valves are open.
