Davey Torrium2 provides automatic pump control for clean-water household supply, irrigation and water transfer. It starts the pump when water use causes pressure to fall, keeps it running while water is being used, and stops it when flow falls below about 1LPM. The plug-and-play version connects to a compatible pump through an Australian three-pin socket.
Inlet: 1" BSP male thread.
Outlet: 1" BSP male thread. The horizontal outlet rotates to suit the pipework; a vertical outlet is also available.
Maximum controller system pressure is 1000 kPa. Water temperature must remain between 1°C and 70°C; maximum ambient temperature is 50°C. Use clean, non-volatile liquids without fibres or solids. Other applications include washing systems and pressure boosting.
The controller version must suit the pressure the pump can produce with all outlets closed, as well as the pump’s electrical load. The 1000 kPa rating is the controller’s pressure limit; it does not mean every version suits a pump that produces that pressure.
When you close a tap, flow falls and the pump builds pressure before Torrium2 stops it. The controller remembers the pressure reached. Next time water is used, it normally restarts the pump once pressure has fallen by about 20% from that remembered value. This sets the restart point automatically. A dripping tap or slowly leaking toilet cistern releases water a little at a time, so pressure falls slowly. Torrium2 can wait until the pressure has fallen further before restarting the pump, increasing the time between starts. When normal water use resumes, it returns to its normal starting behaviour.
Dry-run protection stops the pump when Torrium2 detects a loss of prime. This means the pump no longer has enough water inside it to pump normally, which can happen if a supply tank empties or air enters the suction pipe. Torrium2 then retries at increasing intervals. The controller also stops the pump if water becomes too hot or it detects excessive electrical current. Lights show whether the pump is running, standing by or has a fault.
A small internal spring-loaded chamber holds a little water under pressure, helping reduce repeated starts during very small water draws. It does not need air-charge checks. An optional pressure tank up to 18L can be fitted to the vertical outlet to store more water between pump starts.
The housing is glass-fibre-reinforced nylon, with a 316 stainless steel sensor plate and nitrile O-rings. A built-in check valve helps retain pressure when the pump stops. A built-in surge protector helps protect the controller electronics from power spikes.
The controller has a 2m incoming power lead with an Australian three-pin plug. The plug-and-play version also includes an Australian three-pin pump socket intended for indoor installation. An outdoor plug/socket connection needs suitable weather protection.
Mount the controller with access to the priming point, prime button and status lights.
