Item Notes
Circulation pump The pump must be able to deliver at least the minimum required flow (including
pressure drop in supply and return line) at all times.
Flow meter or flow
switch
Used to monitor that the required flow of coolant is maintained during pump
operation. The flow meter should have an electric output that can be wired into the
pump power supply circuit in such a way, that the pump is stopped if the flow of
coolant is interrupted.
Coolant in Supply line (coolant in) and return line (coolant out) should both be fitted with
valves so that the pump can be isolated from the cooling circuit during service.
The supply line should also be fitted with a three-way connection and valving so
that the cooling jacket can be drained before service work. See Fittings needed to drain
cooling jacket (page 38).
For P- and S-installations, two 1-inch inner diameter reinforced water hoses are needed. To avoid
movement in the sump, they should be fixed with cable ties to the cables.
For T- and Z-installation, pipes should be used instead of hoses to minimize the risk of accidental leakage.
Flexible connections (for example, reinforced hose) from the pipe to the pump are advised, to avoid
transmitting vibrations from the pump to the pipes.
External cooling, open loop
NOTICE: It is extremely important that the cooling water flow is maintained at or above the desired
minimum level while the pump is running.
For an open loop system, the cooling water supply should be arranged as shown in the figure below.
