Connection type 1
The external cooling fluid enters through the hole in the stator housing marked “cool in”.
This requires that the plug is replaced by a hose coupling nipple and hose. The fluid exits
at the impeller and the lower seal. For this type of connection, one of the sleeves between
the oil housing and the stator housing must be replaced with a solid plug.
Connection type 2
The external cooling fluid enters through the hole in the stator housing marked “cool in”.
This requires that the plug is replaced by a hose coupling nipple and hose. The fluid exits
through the hole in the stator housing market “cool out”. This requires that the plug is
replaced by a hose coupling nipple and hose. For this type of connection, both of the
sleeves between the oil housing and the stator housing must be replaced with solid plugs.
Monitoring equipment
The following applies to the monitoring equipment of the pump:
• The stator incorporates three thermal contacts connected in series that activate the
alarm and stops the pump at overtemperature
• The thermal contacts open at 125°C (257°F).
• Ex-approved pumps must have thermal contacts connected to the control panel.
• The sensors must be connected to either the MiniCAS II monitoring equipment or an
equivalent equipment.
• The monitoring equipment must be of a design that makes automatic restart
impossible.
• Information in the junction box shows if the pump is equipped with optional sensors.
Optional sensors
FLS FLS is a miniature float switch for detection of liquid in the stator housing. Due to its
design it is best suited for pumps in a vertical position. The FLS sensor is installed in
the bottom of the stator housing.
The data plate
The data plate is a metal label that is located on the main body of the products. The data
plate lists key product specifications. Specially approved products also have an approval
plate.
