Pumps for chocoholics
Tapflo Pumps has just had all chocoholic dreams come true.
The pump is built with a secondary, double diaphragm.
Under normal operation the chamber between the backup diaphragm and the wetted diaphragm is set to vacuum by the control system.
In the unlikely, but potentially hazardous, event of a diaphragm rupture, the pressure will rise in the vacuum chamber.
The control system will then switch off the pump and switch on an audible alarm.
The leaking liquid will remain in the chamber between the wetted and backup diaphragms and this provides a high level of safety because the liquid is never allowed to leak into the environment or air system.
Ideal for use in explosion hazardous areas as no electrical components are used, the complete system can be mounted on a special trolley built from 316 stainless steel and fitted with antistatic wheels.
A bunded area on the trolley contains any leaked liquid during service.
