PCR pumps have been transferring lime slurry, whose density per litre can vary from 100 to 600 grams, for almost 40 years.
NOur proposal will depend on your needs, your installation and its constraints, such as the volume of water to be treated.
The most common arrangement is as follows: The pump draws the lime slurry into a tank equipped with a mixer, either by direct tapping (loaded pump) or by means of a (gooseneck) pipe.
The pump drives the lime slurry through a pipe (preferably flexible, spiral) to the water tank to be thinned.
We recommend using hose barb couplings to avoid any air intake. The flow rate (and therefore the speed) of the pump is automatically controlled by a frequency board, generally located in the station’s electrical control cabinet. This frequency board is connected to a PH meter, which measures the hardness of the water. The ‘reverse’ function of the frequency board allows the direction of the pump to be reversed, to clean the entire network and to avoid any risk of decantation in the event of an extended shutdown of the installation.
