| Tests undertaken to measure the performance of a standard pump against the new TC intelligent pump have resulted in an energy saving of up to 70%.
The extensive testing procedure has shown that the largest amount of energy required by a pump is used to overcome the resistance created by the pump itself. Another major issue is found in the mid-port scenario, wherein the attempt to save energy by turning down the air pressure to a much lower level causes the stall of the pump. The pump fitted with LEAP® Technology is able to start pumping at 0.3 bar without stalling, in test the pump was already achieving flow rates of 70% of its maximum open end flow before other pumps had even started. |

Graph showing fluid flow against air pressure required
The TC Intelligent pump can operate in two settings, Internal and External Pilot.
Internal Pilot
In standard conditions the pump runs with a single air supply from 0.3 bar, deriving air supply to the control module from the Internal Pilot – main air supply.
External Pilot
In some applications however, there may be a need to use the External Pilot – a separate (additional) air supply to the LEAP module.
The EP assists in moving the air valve in application of:
TC intelligent pump ports
Guardian systems
The Guardian is an energy conservation device designed to protect an air operated double diaphragm (AODD) pump from operating in an inefficient manner that uses unnecessary energy and reduces the life of its parts. It also offers the added benefit of providing greater safety to applications of high risk.
The Guardian directly monitors the discharge fluid pressure against its set point stopping the pump if the media pressure increases above the set point (closed valve) or falls below the set point (dry-run) dependant on configuration.

Applications of Guardian systems
Barrier Protection
Barrier pumps (TB) have an additional set of diaphragms used to back-up the primary diaphragms. In case of a breach the liquid remains inside the pump, instead of leaking out through the air exhaust. The Guardian monitors the pressure between the primary and secondary diaphragms, stopping the pump if the pressure increases above the set point.
Dry run & stop
The Guardian monitors the fluid discharge pressure of the pump, stopping it if the pressure falls below the set point, caused by a lack of media on the suction causing air to be ingested into the pump.
Dead head & stop
The Guardian monitors the fluid discharge pressure of the pump, stopping it if the pressure rises to the set point, caused by a closed valve or over pressure in the discharge line.
Dead head & restart
The Guardian monitors the fluid discharge pressure of the pump, stopping it if the pressure rises to the set point, caused by a closed valve or over pressure in the discharge line. When the pressure falls below the set pressure, the pump automatically restarts.
