Internal Pump Wiring
If the Wilo RS 25/7.5 PWM pump does not have the required flow rate, a second Wilo RS
25/7.5 may be added to increase the total pump pressure and flow. This will double the
head pressure capability at the targeted flow rate. When adding a booster pump, wire
both power and control wires in parallel with the internal Wilo pump wiring. Use the
same terminals. See diagrams next page.
