How to maintain Bio-Pure air pumps  

bio-pure_banner

As the Bio-Pure Sewage Treatment System has no moving parts, it operates by the use of an air pump which provides the extended aeration method used to break down sewage so successfully and discharge such clean effluent. These pumps need to be properly maintained to ensure perfomance is kept at its peak.

We provide service kits if you wish to maintain the pump yourself. We also offer service agreements where all aspects of maintenance are covered beyond just the air pump.

Please see our servicing page for more details on our service agreements and what is included in them. Alternatively, please fill out the service quotation form

This is a typical air pump found in our Bio-Pure Sewage Treatment Systems. In larger systems. The pump is found under the 730mm square lid along with the alarm. 

Maintenance takes a small amount of time and will improve the life span of the pump saving you money in the long run.

The air filter in the top of the pump can get clogged and blocked up during use. Cleaning this is advised after 6 months and replacing after 12 months, especially in dirty environments, as blockages will cause the diaphragms to overheat and work at a faster rate resulting in them splitting. If you wish to service the pump yourself, it is also just as important to refit the diaphragms correctly as this will cause them to break again if they are not fitted properly. 

In our standard service kits we include a pair of diaphragms, an air filter and 4 magnet support jigs. The magnet support jigs help to line up the diapragms with the magnet. 

It is very important that the support jigs are used to align the diaphragms correctly, if these are misaligned then this will cause degradation, a shortened diaphragm life span and can also cause complete pump failure.

It is very easy to identify any problems with the air pump. A red service light will appear on the side of the pump if it detects a problem, this will often be due to the diaphragms splitting. This red light is also an indication that the pump has stopped itself from working to prevent further damage via a cut off switch found inside the pump. 

Also if the filter or diffuser is blocked, the sound levels coming from the pump will rise as they are overheating and therefore working at a faster rate. This will lead to them eventually splitting. 

The diffuser can often be blocked following the accumulation of excessive amounts of wipes. As these wrap themselves around the end of the diffuser, the air pump has a lot less space to blow air through, causing the pump to work faster, become noisier and overheat, eventually resulting in the pump failure if the problem is not corrected.

The air pump typically operates at a very low sound level and isn't hot to touch, so it won't be difficult to diagnose a problem.

The Integral Alarm

The alarm fitted with all standard units will also tell you if there is a problem with your pump. 

If you have a gravity fed system, the alarm will bleep once for loss power, this is if there is no electrical current flowing to the pump.

It will bleep twice to signify an issue regarding air pressure. This can be caused by loose jubilee clips, the air hose not being properly attached to the pump or an oversensitive pressure switch.

In pumped systems, the alarm signifies the same possible problems as a gravity fed unit. 
However, a pumped alarm not only informs you of loss of power and air pressure, but also a high water level. This is signified by three bleeps. If the pumped alarm is bleeping three times, it is essential that you get in contact with us as your unit will be likely to flood.
