based on their boiling points . Next , the vapours of these substances condense on the trays and are collected . Gas oil is collected from near the bottom of the distillation tower , just above marine fuel oil .
So what ’ s the difference between gasoline or petrol , and gas oil ?
Both diesel and gasoline are petroleum products refined from crude oil . However , gasoline or petrol is more refined than gas oil , which makes it thinner in density and more volatile . So petrol burns faster , which enables it to produce more power or horsepower , making it perfect for lighter vehicles that need less torque and more horsepower to go faster .
In contrast , gas oil is thicker , evaporates much more slowly and has a higher energy density . This means that it produces 20 % more energy than petrol from the same amount of fluid . This is why diesel like gas oil is more suited to powering big machines because it can generate more energy at lower RPMs and provide more pulling power .
What did we specify for this project ?
At North Ridge Pumps , we ’ re not limited to specifying just one type of pump .
As the UK ’ s largest pump supplier with over 25 years ’ experience , we ’ re highly skilled at providing engineered pumps for a wide range of applications . We use this know-how to deliver a tailor-made solution for each client , not a standard product straight off the shelf .
Above all , we choose the best pump for every project – offering the lowest lifetime cost . For this specific job , we chose two of our XHLE longcoupled , end suction , single stage pumps . These are large , heavy duty horizontal centrifugal pumps with both high flow and high-pressure capabilities .
Both gas oil pumps will deliver around 180m ³ h ( 3000 L / min ) at over 5 bar of pressure , and the client wanted this particular design
Above all , we choose the best pump for every project – offering the lowest lifetime cost .
because it can operate at up to 80 % efficiency . They ’ re also fitted with a brass coupling guard , ATEX motor and are long-coupled and aligned on a baseplate .
Well-engineered pumps with builtin product benefits
Our XHLE long-coupled , single stage pump is standardised to comply with
EN 733 / DIN 24255 , which means that the design is exactly the same size as many other pumps on the market .
It can therefore replace most horizontal centrifugal pumps that are already installed , and indeed , is suitable for a wide range of applications in the industrial and marine sectors .
The XHLE long-coupled horizontal centrifugal pumps we supplied have ATEX motors which are mandatory for handling flammable fluids like gas oil .
