The Fuel Recirculation Unit was developed to prevent diesel fuel inside a storage tank from getting stagnant - particularly those with low usage such as generator back up tanks, that whilst not regularly used are of vital importance. When fuel sits stagnant for long periods of time, microbial growth known as diesel bugs begin to form, join together and create a nasty biofilm. By keeping the fuel moving and free of the contaminants that can get sucked into pumps, equipment and vehicles, costly damage and downtime can be avoided.

The fuel storage tank circulation system draws the fuel up from the front of the tank through the magnetic conditioner, which stuns the bugs, breaking them down into a size that will pass through a two stage water and particle filtration process to remove any impurities. The cleaner fuel is then circulated back into the tank, before the bugs have been able to group and create the nasty sludge.

The storage tank recirc unit has an input for connecting to an alarm/gauge to detect a low fuel level and a leak probe for a drip tray (if installed). Benefiting from a control panel with large, coloured lights, any issues that need to be dealt with i.e. filter blocked, low fuel level, a leak or a system fault can be easily diagnosed. If the system identifies any of the above issues, the pump will turn off until necessary action has been taken as a safeguard. Complete with two BMS outputs, the control panel can also send a signal of this to warn users remotely.

There are two versions of Fuel Tank Circulation System; one for circulating (50lpm) a maximum of 3000 litres per day for tanks up to 40,000 litres, and another for circulating (70lpm) a maximum of 4000 litres per day for tanks up to 70,000 litres. Tank contents should be recirculated every 28 days to prevent bacteria colonies from forming. Our systems are set to turn over 1.5 times the tank contents every 28 days to include a safety margin.

The Piusi E140 electric diesel transfer pump is the latest, highest flow addition to the industry known "E" range of diesel refuelling pumps from the established Italian manufacturer. The Piusi E140 has the same powerful, reliable and high quality design as the other diesel transfer pumps in the range, but at 140lpm benefits from an even quicker flow rate making it suited to high volume transer applications such as refuelling larger vehicles and machinery, and larger scale tank to tank transer. 

This mains powered Piusi pump has a 1 ¼” BSP inlet and 1” BSP outlet and contains a pump head, motor and an integrated bypass valve. The E140 is constructed from cast iron, supplied with an on/off switch and has thermal motor overload protection allowing continuous running.

Please note: Suction hose must be 1 ½”, delivery hose must be 8m max. The E140 has opposite flow direction compared to other Piusi pumps i.e. E120.

This diesel delivery hose assembly is a premium solution designed for gravity fed and low pressure pumping installations. Suitable for use with oil and diesel applications, this fuel hose is available in a range of lengths to meet your requirements.

The premium fuel dispensing hose assemblies come with swaged stainless steel full ferrules and BSP hose tails with sealing o rings. As well as in an assembly, this diesel hose is available by the metre and in coils if you have a large requirement.
