Automatic Bund Pump/Alarm


As recommended in DEFRA 2001 Oil Storage Regulations

“YES to water – NO to oil”
Automatic Separating Pump System

The Problem

Any tank, drum or plant containing more than 200 litres of oil must be provided with some form of secondary containment of “bund”, to retain leaks, spills or worse.

By law the bund must be capable of holding at least 110% of the contents of the main oil tank. Larger oil storage tanks and equipment such as electricity transformers may contain several thousand litres of oil and are likely to be open to the elements. The bund will collect rainwater and, before too long, the holding capacity of the bund will be significantly reduced. Obviously as oil floats on water, once the capacity drops below 100%, there is a risk of oil escaping over the bund wall in the event of tank failure.

The Solution

The PPL BundGuard system was developed over ten years ago specifically at the request of the UK electricity industry who faced serious water removal problems at sub-station sites all over the country. Since then, many thousands of BundGuard units have been installed and nearly every one is still performing well, even after all this time.

BundGuard is a low-cost, self-contained and easy to fit automatic pump and alarm unit which works continuously and automatically 24/7, 365 days a year.

Using advanced circuitry and approved micro-chip technology the system discriminates between oil and water. The robust, all stainless steel, pump/sensor unit locates in the sump and monitors the different liquid levels. The control unit activates the pump as required to remove only clean water safe to send to foul sewer or interceptor (depends on site circumstances). Failsafe systems and a range of visual and relay alarm outputs ensure complete safety and allow onward communication to remote monitoring systems.
