Iron and Manganese Removal

15 August 2017 by David Critchley


We have two methods of removing Iron and manganese from water depending on the chemical composition:


Catalytic Oxidation

This method uses a filter media as a catalyst to oxidise dissolved iron in the water, to a form which will drop out of solution and become trapped in the filter media. This is then periodically backwashed to waste by an automatic control valve.

Catalytic oxidation is a simple, cost effective technique for removing iron As the media is used as a catalyst, it is not depleted and does not need to be ‘toped up’.





ION Exchange
This method uses an ionic exchange resin, to trap dissolved impurities in the water. Periodically, as the resin becomes depleted, it is automatically re-generated using a small amount of salt. The impurities are then backwashed away to waste by an automatic control valve.

Ion exchange works best on clear water, i.e. when the iron/manganese are in a dissolved form and will also reduce hardness with no extra treatment.

With this method, pH correction, iron/manganese removal, ammonia reduction and softening can all be addressed in a single process, leaving crystal clear soft water.


Which is best?
Generally, we would recommend a Catalytic oxidation system unless Manganese levels are high and/or pH is low. In which case, we would probably suggest an ion exchange system. The key to getting it right is to have the water tested, so we know exactly what we are dealing with. We have a quick, self-test kit which we send to you by courier and collect on the day of the test. The sample is analysed at the laboratory and a report issued, comparing the sample against the Private Water Supplies Regulations. If you already have a test report, send it to us at 

We can then design a bespoke system, tailored to your requirements.



Slurry and Effluent pumping can be a nightmare!

12th May 2016 by Chloé Bleackley


You need to be prepared to manage the silage, sludge, slurry and sewage which will be your priority in the upcoming weeks. These types of substance are the trickiest to pump; they are corrosive, and easily block pump impellers and chambers. We are experts in dealing with these types of challenges, so we want to help you through this season.

You won’t have to worry about the abrasive, corrosive substances wearing away at your pump anymore. Our pumps are manufactured from corrosion resistant stainless steel.

Pumping straw, silage, animal hair and any other types of fibrous materials will no longer jam or block your pump.Our pumps don’t block and pass it through without any issues.

We know how much trouble can be caused when a pump stops working, particularly because of all the regulations set by the SEPA regarding pollution and water causes. Our pumps are reliable and come with a 2 Year Guarantee; all pumps are stocked high so if you do have any unlikely issues we can send you a replacement the next day.

We’ve been advertising these pumps in the Farmers Guardian and Scottish Farmer publications for years; they are favoured by farmers all over the UK!

Here’s what Nottinghamshire based farmer Roger Beckett said about our pumps…


“After experiencing the same problems year after year when slurry pumping, I thought my system would never work effectively. That’s until I spoke to Whisper Pumps, they helped me choose a submersible pump which doesn’t block after every use and since then my system has never worked better.“

Dependent on your specific requirements the 2 pumps which we’re talking about are the Ebara DW Series & Right Series. Call us now on 01777 871100 and we’ll advise you which pump you’ll need to help you through this important season.



Tell tale signs it's time to replace your borehole pump...

3rd March 2016 by Chloé Bleackley


You’ll be pleased to know the only time to replace your borehole pump is when it stops working.

Many of our customers contact us concerned their pump has reached a certain age so should they consider replacing it? The answer is Not Always; if you look after your system, your pump could last for 20 years!

Here are a few ‘signs’ which may be concerning you…


1.       Some of you may notice a dip in flow rate and think it’s time to replace your pump. Iron fouling is the most common cause of reduced flow rate and many boreholes within the UK are prone to iron deposits in one form or another. We supply a product called Fe-GON, an inexpensive removal remedy to treat iron oxide or manganese fouling. It’s much, much cheaper than replacing your borehole pump and once treated, your flow rate should return back to normal!


2.       Does your pump cycle on and off rapidly? If Yes, It’s likely the pressure settings are incorrect. Not enough people regularly check their expansion vessels pressure setting and this is one of the biggest causes of failure. If your pump is cycling on and off rapidly, check your settings; for instructions on setting the pressure click here for our step by step guide.


3.       Failed start capacitors are one of the biggest misconceptions of a pump failing. Never just assume your pump has failed as it may be something as simple (and inexpensive!) as the capacitor. This component is necessary to start single phase borehole pumps, is located in the control box at the top of the well and looks like this:

To summarise: Do not assume it’s time to replace your borehole pump – the ‘signs’ could mean a number of less expensive remedies. If you’re experiencing any of the issues discussed above and would like further information, do not hesitate to contact us here or call us on 01777 871100 for expert advice. 




Protect Your Pump this Winter

10th December 2015 by David Critchley and Sarah Sinclair


With the recent, un-seasonably mild weather, it’s easy to forget that we need to protect our pumps from the perils of Jack Frost. When the temperature drops; and it will, here are a few tips to protect your pumping system from damage.

1)  Insulation is key. Insulating your pump gives protection against the cold to stop your pump from freezing. A simple way of insulation is to wrap the pump in bubble wrap (taking extra care to not restrict the airflow around the motor).

2)  Keep thpump switched on. Allow the pump to keep running by leaving a tap partially open. This will help to protect against freezing but you must be careful not to run your pump against a closed head as this will cause it to over-heat.

3)  Drain the system. All pumps have a drain plug at the lowest point. Be sure to remember that any pipework or control equipment will need to be drained too.

4)  Heating.  If temperatures fall significantly and your pump isn’t insulated. Have a small heater set up close by which will protect the pump against freezing.



For water wells in particular, it is important to remember that frozen pipes or control systems can damage a submersible pump if it does not switch off. There are a few different steps you can take to protect your pipes from freezing this winter:

1)  Insulate. Lag the pipes and control equipment.

2)  Install. Heating

3)  Cover. Make sure that the well is covered up securely.

4)  Drain. If you cannot protect the system, drain it down.

Don’t get caught out, act now to eliminate any unnecessary costs and problems during the winter months.

If you have any questions, please do not hesitate to call us on 01777 871100.

Harvest season is coming to an end, and we know that an important factor to consider during this period is time. Making sure your machinery has enough fuel through cultivation is an important necessity. That’s why we have carefully selected our best fuel transfer products to enable you to refuel quickly and efficiently. 



Our high volume diesel pump and high speed automatic nozzle are ideal for the job at hand! By using both of these products, it would take less than 2 minutes to refuel a tractor over 400 litres in capacity!

So, why are these products a must have? This combination will allow for you to refuel in next to no time at all. With less mess, less fuel waste and a reduced filling time, don’t miss out on your chance for an easier time after a hard harvest! Connecting hose and fittings are also available on request.



High Volume Diesel Pump

In more detail, this self-priming pump has a sturdy, long life cast iron structure along with oil resistant seals and gaskets. To avoid the loss of diesel once the pump has stopped, a non-return valve is incorporated to the inlet of the pump so that the diesel can flow in, however cannot make its way back out. This makes the process of priming the pump a lot easier the next time it is used.

High Speed Automatic Nozzle

Our high speed nozzle shuts off the flow of the fuel when the tank is full. This means there is less fuel waste and reduced mess as it will only fill to the top and not overflow. The nozzle is perfect for refuelling diesel up to 250 l/min into tractors, large agricultural or plant vehicles.

6 things to consider before choosing the right pump for the job

7 September 2015 by Sarah Sinclair


Choosing a pump can be difficult and since there is such a vast choice of pumps available, we know it can be quite overwhelming. By following these quick steps, you will be able to provide us with all the information we need in order to choose the perfect pump to meet your requirements.


1.    Fluid Type.

The first thing to consider would be what type of fluid you wish to pump. This could be clean water, water with solids up to 10mm/30mm/50mm or another fluid you are wanting to pump.


2.    Type of Pump.

The next thing to consider is whether your pump needs to be submersible (to operate under water) or whether it would need to be surface mounted.

Please note: If the pump was to be surface mounted, a suction lift would need to be specified.


3.    Power resource.

Another thing to consider is what power will be available in order to pump fluids. This could be either 110v, 230v/1Ph or 400v/3Ph.


4.    Flow Rate.

Next you would need to consider whether you require a specific flow rate (the volume of fluid which passes per unit time).


5.    Pressure/ Delivery Head.

Delivery head is the pressure/height at which the specified flow rate is required.


6.    Delivery Pipework.

This is the pipe in which liquids will pass away from your pump. The required size will need to be specific to where you will be pumping to.


Once all this information has been gathered, you can input this data into our pump selection questionnaire here, or if you wish to speak to one of our specialist engineers, they will be able to utilise this information to choose the best pump for the job.
