Pump Options A variety of pump options to suit a wide range of applications is available:
Factory fitted in line as a single pump or run/standby configuration and available
in standard and larger nominal external head pressures.
Factory fitted run/standby pumps have a shut off valve to the inlet and a non
return valve to the outlet, enabling one pump to be maintained without
interrupting Chiller flow. Supplied with electrical switchgear and isolating valve
as standard.
Run/standby pumps are rotated automatically to ensure even pump usage and
prolong component life.
