Mechanical Seal Pump
The pump used for the thermo-chiller HRLE series uses a
mechanical seal with the fixed ring and rotary ring used for the
shaft seal part. If foreign matter enter the gap between the
seals, this may cause a trouble such as leakage from the seal
part or pump lock. Therefore, it is strongly recommended to
install the particle filter in the return piping of the chiller.

Pump Capacity
Required Facility Water Flow Rate
* This is the facility water flow rate at the circulating fluid rated flow and
the cooling capacity listed in the ”Cooling Capacity” specifications.
* The pump capacity is the capacity of CH1 when 2 L/min are applied
to CH2.
