The ability to create a successful and safe solution to a problem which other pump manufacturers had not been able to solve has lead to a Mono Merlin pump being fitted to a new custom-built, fuel oil delivery vehicle.

Lancashire-based Ruttle Plant Hire required a pump that would discharge the diesel fuel from the new tanker. While other manufacturers could only offer petrol-driven pumps that were unsuitable from a safety aspect, Mono was able to supply a Merlin progressing cavity pump that is driven by the power from the vehicle itself. The customer now has a fuel discharge system that works reliably and has proved to be so efficient, that it has reduced the duration of the daily fuel delivery round by over two hours.

In addition to providing a safe and efficient solution to Ruttle's requirements, the Merlin pump fitted to the 3,000 litre capacity tanker offers other significant benefits. With a typical operating speed of 700rpm and delivering up to 100 litres/minute of diesel fuel oil, at 3 bar pressure, the ability to vary the power take-off from the vehicle allows the pump to operate at different speeds. The pump can deliver fuel in appropriate quantities to various sizes of machinery ranging from large earthmovers to small mechanical diggers.

Since the new tanker first hit the road in September of last year, the Mono Merlin pump has worked consistently and has so far has delivered over 250,000 litres of fuel oil.
