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.
The Merlin Industrial range has 20 models available in both cast iron and stainless steel construction and is
capable of handling applications up to 10 bar and capacities up to 60 m3/h. The normal operating characteristics
associated with PC pumps are also applicable to the Mono Merlin pump. They are capable of self-priming, can
operate in either direction and have a gentle, smooth pumping action which maintains the product integrity.
This simple construction results in a pump range that is extremely reliable and easy to maintain. PC pumps can be
found in use throughout many industries ranging from water and sewage through to chemicals and food, and are also regularly chosen for applications involving all types of pumped media from delicate gels and solids in suspension, viscous or abrasive substances. Backed by Mono’s extensive technical support and outstanding experience of engineered pumping solutions, they can offer an ideal solution to many types of pumping requirement.
