Oil Burner Pumps

Oil powered burners require an oil pump. The oil pump runs for several seconds at startup (usually on the low-pressure side of the pump) to purge the boiler of any unwanted gases. After a preset period, a solenoid valve opens on the high-pressure side of the pump to allow oil to be fed to the nozzle, which is designed to atomise the oil to the smallest droplets possible where it is mixed with the incoming forced air from the fan. 

 

 On a heating plant, many different types of pumps are used, their common task is to move liquid. The design and method of operation of a pump will depend partly on how much liquid it must deal with and partly on how much pressure the pump must yield. There are many different types of fuel pump for different purposes including, Centrifugal Pumps, Piston Pumps and Gear Pumps.

Kerosene Oil tank

Why do oil burner pumps fail? 

Oil burner fuel pumps are often the main cause of a broken down burner. We have heard many a story of disgruntled customers complaining to the installer or engineer that the new burner shouldn't break down this soon! The cause? Usually dirty or contaminated oil, or water in the oil. The pumps are lubricated by the fuel passing between the gears, if this contains pure oil, perfect, but if the oil is contaminated with water, this causes all sorts of issues mainly within the pump.

1. Checking your oil pump

The easiest way to check your existing pump for contamination is to isolate the oil supply and remove the pump. If when you open it up you see any brown 'gunk' or signs of rust, you more than likely have water ingress in your fuel. 

 

If there are no signs of sludge or rust, the pump may have failed mechanically in which case providing it is within the warranty period, it may be liable for replacement or repair.

Oil and Water

2. Identifying the cause

The water usually enters the pump at source, ie in your tank. This may not be through direct means, ie a leaky tank; rather its usually through condensation. Any air that gets into the top of the tank, when it is being refilled, or passing the seal will contain moisture. When the temperature drops the moisture condenses and ends up in your oil. A few droplets don't cause too much of a problem, but over time these accumulate and eventually damage the pump.

3. Keeping my oil clean

There are a few simple steps that can help with this. The simplest is to fit a drain tap to the tank that feeds your oil pump. This will allow you to drain off any water that has accumulated.

 

A water trap or filter can be added to the feed too, this will need to be emptied regularly.

 

On larger Industrial and commercial installs, a tank dryer is usually a far better preventative.This will as the name indicates ensure that all air above the oil is dry.
