Ideal for pumps with clean, non volatile liquids without fibers or solids such as household water supply, irrigation, water transfer, washing systems and pressure boosting applications. OPERATING LIMITS Maximum system pressure 100psi Capacities to 45 gpm Recommended pump shut-off head range: T45 22 - 65 psi; T70 65 - 100 psi Maximum ambient temperature 122oF Maximum water temperature 158oF Minimum water temperature 34oF Torrium® cut-in pressure is normally 80% of the pumps last shut-off head. FEATURES AND BENEFITS All parts of the Torrium® that are in contact with the water are manufactured from safe, corrosion resistant materials for: • Consumer confidence that their water supply will be as good coming out as it was going into the system • Ability to use the Torrium® on a variety of water qualities Compliance with the strict requirements of ISO 9001:2000 quality standards ensures consistency of quality of the system. Torrium® starts pump on pressure drop and stops pump on low flow (~0.5 gpm), thus reducing pump cycling for constant and even water pressure. Torrium® measures the pump shut off head each time the pump stops, and sets the cut-in pressure at 80% of shut-off head, so that the consumer is unlikely to notice any pressure change when the pump is switched on. Torrium® adapts each time the pump stops, thus allowing the system to accommodate variations in pump performance or site conditions. Torrium® has a simple indicator and fault LED system. Red constant means that the system is in standby. Green constant means the pump is running. Cistern Fill mode is activated when the Torrium® detects frequent short cycling, such as may be encountered with a very slow filling toilet cistern. The Torrium® will then ensure the pump continues to operate for at least 2 minutes. Torrium® stops the pump in loss of prime circumstances and activates the “loss of prime” LED indicator sequence (red LED single flash per sequence), thus:- • Protecting the pump from dry run damage • Helps identify installation faults When the Torrium® detects loss of prime it waits 5 minutes then goes into auto retry mode, whereby it will restart the pump to see if prime can be re-established automatically. Auto retry occurs at 5 minutes, 30 minutes, 1 hour, 2, 4, 8, 16 and 32 hours. Torrium® will also retry if it detects flow through the system (eg from mains water pressure returning). If Torrium® detects excessive electrical current, such as when a the pump motor is subjected to locked rotor or when someone tries to manually override the Torrium® by holding in the prime button, the Torrium® will shut the pump down and indicate 2 red flashes per sequence. Should the Torrium® detect low incoming voltage (below 90 volts for 110-120 volt models and 180 volts for 220-230 volt models) it will allow the pump to continue to operate if possible, but it will flash two red flashes per sequence over the green run LED. Water over-temperature cut-out fail safe protection provides a second level of protection against loss of prime and / or closed head operation and / or repetitive cycling for added security and longer life. In the event of the Torrium® detecting water over-temperature above 158ºF it will shut the pump down and flash 3 red LED flashes per sequence. Once the water temperature has dropped to below 140ºF, the Torrium® will allow the pump to restart. Torrium® also detects slow leaks and attempts to overcome the short run times such leaks can cause by dropping temporarily the cut-in pressure to 50% of the last shut-off head. Torrium® will return to 80% cut-in pressure after 100 cycles or if a manual reset is initiated. Torrium® has no moving parts in the waterways:- • No parts to jam means improved reliability • Less reduction of pump performance • Reliable usage with varying water quality Corrosion and scale resistant flow and pressure sensors mounted on a high grade titanium plate. Special anti scaling electronic functions allow Torrium® to be used with water of varying quality. Torrium® has an in-built spring loaded pressure tank, overcoming the need for regular pressure vessel air charging and checking. Right angle discharge rotatable around full 360o, with optional pressure tank mounting position on top, facilitates:- • Easier installation and connection to plumbing • Use with a choice of optional pressure tank sizes Incoming power lead fitted is 6 feet long with applicable NEMA three pin plug. Power lead to pump motor is 2.2 feet long with connection for standard Davey motor up to 10amps.
