'The Guardian System'
4-in-1 Protection..
Tapflo’s newly developed ‘Guardian System’ is the ultimate in pump & system protection, designed and manufactured by Tapflo this unique & ground breaking product can monitor & protect many pumps.
Barrier Monitoring System -
The Guardian system monitors the pressure in the void cavities of a barrier pump, pipe work, tank or vessel. If the pressure in the void increases above the set point due to either a media breach or mechanical failure, the system will issue a signal that can be utilised to sound an alarm, stop the pump, etc’.
The diaphragm is PTFE faced as per the fluid diaphragms of the pump, therefore is completely tolerant of most media and is therefore much safer than conventional systems. Some of the advantages are;
Prevents & contains spills associated with diaphragm failure in air pumps and seal failure in electrical pumps
Continually monitors barrier pumps, tanks, vessels & pipe work
for leaks
Inherently safer than other barrier systems on the market
Dry-run Prevention -
stops the pump automatically if the discharge pressure falls below the set pressure of the system. Under normal running conditions the pump will run at a discharge pressure proportional to the application, if the suction line becomes exposed the fluid pressure in the discharge line will collapse and the system will issue a signal that can stop the pump.
Minimising potential damage due to dry running
Reduces air consumption/wasted energy, by stopping the pump when it is not required
Enables ‘lights out’ operation that will automatically stop once the transfer is complete
Optional volt free contacts for electrical applications
Dead-head & Stop System -
The Guardian system automatically turns the pump on/off dependant on the discharge pressure of the pump. Under normal running conditions the pump will run at a discharge pressure proportional to the application, if dead-headed (i.e. the discharge valve is closed) the fluid pressure will rise. The system recognises this and stops the pump until the discharge pressure reduces due to the valve being re-opened, automatically restarting the pump. Some of the advantages are;
Reduces pressure in lines when no demand is present, reducing potential leaks and pipe bursts - increasing safety
Increased safety when opening the discharge valve
Reduced air/power consumption
Elongated pump life
Over/Under Pressure Monitoring -
The Guardian system can be used to monitor the pressure of media in a line, issuing a signal if it deviates above or below the set point. Some of the advantages are;
Minimising potential damage to the machinery if low or high pressures are experienced
Warns of filter blockage or failure
Indication of pipe bursts or pump failure
