Domestic Water Technology
Protective layer in the pipework
You don't have to simply accept corrosion and limescale. ProMinent metering units add active substances such as silicate, phosphate or silicate-phosphate mixtures to piping systems to create a protective layer. The addition of these substances protects pipework, fittings and appliances such as boilers, washing machines and dishwashers against corrosion and limescale by reducing aggressiveness and hardness deposits in the water.
Keeping things flowing
In a flow of water, the contact water meter transmits pulses with a fixed pulse interval corresponding to the flow to the metering pump. Each of these pulses results in a metering stroke of the metering pump, thereby feeding the metering solution. The metering volume per stroke can thus be adjusted continuously between 100% and 50% using the stroke adjustment dial.
The addition of chemicals must remain constant and the metered volume must always be right. ProMinent domestic water technology ensures this by means of a very low starting limit and a short pulse interval. The best process result is guaranteed from minimum water flow rate to maximum load.
Metering System Promatik®
For flows of 5 – 27 m3/h
The proportional metering system Promatik® is used in the potable water sector for the flow-dependent, adjustable metering of liquid media, like the EXACTAPHOS®. It consists of the metering pump Beta®, a contact water meter, a suction assembly with foot valve and level switch and an injection valve and metering line. more
