AquaForte O Series O-3500 PLUS

Very energy efficient pumps with innovative electronics! Low noise
operation. Provided with synchronous motor. No copper parts. Durable
ceramic shaft. Pump stops automatically when no water is detected
inside the rotor. When the impeller is blocked it will go into a “lock”
position in which the pump does not use power and waits until the
blockage is gone. This will prevent a motor burn out. Competitive priced
dirty-water pumps for water gardens, waterfalls, fountains, filters, etc.
Can pump solids up to 6mm. Suited for dry application (inlet must be
under water level).
