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 Husky 1690 Diesel Nozzle is an extremely heavy duty, automatic nozzle for high flow, bulk fuel transfer for applications including rail, tanker or filling fuel storage tanks. Specially designed for heavy duty applications, this Husky fuel nozzle benefits from a right angle design allowing the nozzle to fit close to walls and corners and has a large hand opening to accommodate for gloves. An added advantage is that it is 30% lighter than other models on the market.

A further feature of the 1690 fuel nozzle is its dual poppet, which allows for the easy opening of the trigger nozzle even when high system pressure is present due to higher flow. Please note models with swivel may have a slightly reduced flow rate.

The Piusi ST200 electric diesel transfer pump is a portable diesel dispensing unit, designed to provide the user with safe and quick refueling. With a flow rate of up to 200 l/min, this Piusi diesel pump doubles the power of the reliable E120 fuel transfer pump, making it a great time saving unit. These diesel transfer pumps also allow for the  installation of K700 fuel flow meter, which measures the fuel dispensed with great accuracy. Featuring a sturdy steel frame, the ST 200 is extremely durable and practical for use.

With the possibility of fitting wheels and a handle to it, this fuel transfer pump is easy to handle and suitable for operating in a work site environment, on vehicles with large storage tanks. The design of this pump allows for the easy installation of an optional K700 fuel flow meter.
