Innovation in Compact Dirty Water Float Switch Operation.
The innovative team at Mac3 has developed the Agma W Evo. They have modified the guiding collar of the original Agma W to allow the float arm to self-level by up to 20 degrees from vertical. This groundbreaking improvement empowers us to tackle the challenges of retrofitting components into existing systems with renewed confidence.
We all know that the Agma W has long been a useful and well adopted float switch. It works on a short-throw, constrained linear axis with magnetic switch activation, which makes it great for sump pump systems and narrow tank level control. However, the original Agma W only operated when installed up to 5 degrees from vertical. The new Agma W Evo with its 20 degree allowance is a real bonus for dirty water pump installations.
Aside from installation into a tank, the Agma W compact float switches from Mac3 are frequently used be OEM suppliers mounted directly to a pump. Pumps of course can move, either in the tank or during maintenance cycles. Having the ability to correct an offset means that if the pump wasn’t set vertically (for example, if there was an obstruction or detritus stuck under the pump itself), with the Agma W Evo deployed it wouldn’t cause an issue going forward, reducing the likelihood of future issues.
As with the other members of the Agma family, the Agma W Evo cannot be used if there are ferrous or otherwise magnetically susceptible deposits in the water, as this can cause issues with the magnets inside the float switch (but then my loyal readers would already know this).
The Agma W Evo will function mechanically the same as the original Agma W and can be used as a direct replacement for the original units if necessary. However, the maximum working differential has been reduced from 150mm to 110mm. This change makes the Agma W Evo easier to work with in smaller tanks or shorter pumps. Nevertheless, when replacing a pre-installed Agma W, it’s important to account for this 40mm reduction.
So, once again, the ingenious Mac3 development team has improved a fantastic product, creating a solution that not only functions effectively but also instils confidence when tackling both new installations and maintenance tasks. This is particularly valuable when dealing with original installations that are not conducive to retrofitting or repair (nothing is ever straight. Ever).
