Davey's BIT Torrium 2 for the Davey BIT Water Pump Systems' TT45Y or TT45P Torrium 2 Intelligent Water Pump Controllers

Davey BIT Water Pressure Systems:

TT45Y - 110V Water Pump Systems
TT45P - 220V Water Pump Systems

The Davey BIT Water Pump Systems consists of a robust centrifugal pump fitted with the intelligent Davey TT45Y or TT45P BIT Torrium 2 water pressure controller to deliver boosted water pressure to your home or other application. Consumers can enjoy strong and seemingly constant water pressure due to the TT45Y or TT45P BIT Torrium 2’s constant flow operation.

Due to large water pathways, the TT45Y or TT45P Torrium 2 operates with a lower head loss than comparable water pressure controllers to provide superior hydraulic performance with less wasted energy.

Davey BIT Water Pressure Systems Applications:

  • Ideal for pumping clean, clear water.
  • Where incoming water supply is not pressurized.
  • From underground or surface water supplies.
  • Automatic water transfer.
  • Applications where the pump may have an interrupted water supply.
  • Domestic water supply, pressure boosting from well or city, automatic water transfer.
  • Domestic and light industrial irrigation.

TT45Y or TT45P BIT Torrium 2 Controllers:

Pressure Boosting BIT TT45Y or TT45P Torrium 2 boosts low or fluctuating mains water pressure to give you strong, even water pressure for your comfort and convenience. The TT45Y or TT45P BIT Torrium 2 can also pressure boost water from rainwater tanks.

Constant Flow and Even Water Pressure:

To prevent annoying fluctuations in water temperature during showers, the TT45Y or TT45P BIT Torrium 2 uses its intelligence to provide households with constant flow to provide even water pressure. It does this with its innovative pressure and flow sensors to start the pump on a pressure drop and to stop it on low flow (~0.26 gpm). This avoids pump cycling when there is continuing household demand for water.

Quick Cut-In for Even Pressure:

To give you strong pressure right from the start, the TT45Y or TT45P BIT Torrium 2 is designed to cut in quickly when it senses demand for water. It cuts in when the pressure has dropped to 80% of the previous top (shut-off) pressure. the TT45Y or TT45P BIT Torrium 2 automatically sets this cut-in pressure each time the pump stops. In doing so, the TT45Y or TT45P BIT Torrium 2 automatically adapts to variations in pump performance or site conditions.

Davey Water Pump System BIT TT45Y or TT45P Torrium 2 Specifications:

The BIT Torrium 2 control starts the pump as soon as you switch on the tap and continues running until water is not required. The controller continuously monitors the flow of water and will switch it off to avoid damage if the supply becomes inadequate. The systems are compact, quiet and easy to install.

The BIT Torrium 2 features a simple indicator and fault LED system. Red means that the system is in standby. Green means the pump is running. The BIT Torrium 2 stops the pump in "loss of prime" circumstances and activates the amber or fault LED indicator, protecting the pump from dry run damage.

When the BIT Torrium 2 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. The BIT Torrium 2 will also retry if it detects flow through the system (e.g. from mains water pressure returning).

If the BIT Torrium 2 detects excessive electrical current, such as when the pump motor is subjected to locked rotor or when someone tries to manually override the Torrium 2 by holding in the prime button, the BIT Torrium 2 will shut the pump down and indicate fault.

Water over-temperature cut-out fail safe protection provides a second level of protection against loss of prime, closed head operation, repetitive cycling for added security and longer life. In the event of the BIT Torrium 2 detecting water over temperature above 158ºF it will shut the pump down and the amber LED will be lit. Once the water temperature has dropped to below 140ºF, the BIT Torrium 2 will allow the pump to restart.

In the event of extremely low flows, the BIT Torrium 2 will delay starting until the system pressure drops below 80% of last shut-off head. In any case, pump start will occur immediately if either the approximate discharge flow from the systems exceeds 0.13 GPM or the system pressure drops to 50% of the last shut-off head. This start procedure occurs every time to overcome pump cycling and improve consumer satisfaction with the system.

Applications Domestic water supply, pressure boosting from well or city, automatic water transfer.
