Pump Options
The pumps can be offered with two options for external static pressure: standard or larger head pressure to overcome
systems with a higher pressure drop. The factory fitted run/standby pumps have a shut of valve to the inlet and a non-
return valve to the outlet, which enables one pump to be maintained without interrupting the chiller flow. Run/standby
pumps are rotated automatically to ensure even pump usage and prolong component life. Electrical switchgear and
isolating valves are supplied as standard.
