Table of actual flow rates for pump SI 1805
The pressure drops defined in this table are
calculated using a 10 mm diameter flexible
connection
Connect a flexible connection with an int. Ø 10 mm (3/8") (not supplied by CARRIER) to the pump discharge.
For OVER models (3 and 5), if using a spreader beam and slings, the PVC tube will not be directly connected to the pump, for handling
reasons. It must therefore be angled in the right direction and fixed to the clamp, as shown below.
