Designed predominately for the air diaphragm pump market the Guardian system incorporates a four-in-one pump monitoring system in both standard and fully ATEX form, with all wetted parts in PTFE.
The Guardian system offers: dry run protection; dead head and stop protection; over-/underpressure monitoring; and leak detection (barrier containment).
Dry run protection is an ever increasing requirement for all pumps, including air diaphragm pumps.
Even though air pumps are designed to run dry, regular misuse will causes unnecessary air usage and reduction in pump life, combined with ever increasing demands to reduce running costs and comply with current energy legislation.
Engineers are constantly looking for the cost effective solution.
The Guardian system stops the pump immediately on dry run detection and is easily fitted with signals to alert users remotely.
Diaphragm pumps are commonly used against a closed valve.
Many clients now require to reduce line pressure during inactive periods to increase both user safety and minimise both leaks and unnecessary air usage.
The Guardian system simply turns the air pressure to the pump off until the line pressure decays to a point where the pump will restart automatically.
The Guardian system enables the user to take both pneumatic and electrical signals (volt free contact) to monitor systems both on over pressure or under pressure ideal for filter monitoring etc The Guardian system can be fitted to all manufacturers' barrier pump designs, offering a simple and highly efficient system to detect breach of either primary or secondary diaphragms with out the use of vacuum.
The system prevents further damage to both pumped media and the conventional antiquated monitoring systems available.
The Guardian system is billed as a giant leap in pump monitoring technology (patent applied for both concept and design) that will reduce air usage, increase pump life as well as protect both users and the environment.
