In 2018 the regulations for drinking water hygiene in Europe were tightened. Applications affected are those where gradual microbial contamination of stagnating water could contaminate the mains water in the event of backflow.
For separating such applications from the mains water, for example buried spray irrigation systems, cattle troughs and service water supply systems as well as dental chairs with a water connection, the pump manufacturer KSB is offering its new KSB Safety Boost break tank package booster set.
This set provides the highest level of protection for liquids of category 5 to DIN EN 1717. The fully automatic, ready-to-connect set is equipped with a vertical high-pressure pump. It is modular in design and mounted on a baseplate. The maximum flow rate per set equals 7 m3/h, the highest head 76 metres.
Pressure control is carried out by an automatic control unit, by means of a pressure switch for the fixed speed version, or by means of a motor-mounted frequency inverter for the variable speed version. All components that can come into contact with drinking water have been approved for drinking water applications. Mains water is supplied to the set via a DVGW-certified flushing valve and a float valve made of materials meeting the KTW and W270 requirements.
The tank has got an effective volume of 100 litres and is made of environmentally friendly, recyclable PPA plastic. All metal components fitted are made of corrosion-resistant, high-quality stainless steels. The tank is designed with a type AB air gap.
The set is easy and fast to commission. Every KSB Safety Boost set is supplied ready-to-connect, pre-assembled and tested. Once the set has been connected to the piping, the 230 V connection simply has to be plugged into a socket (plug-and-play). With the variable speed version, called MVP, the user can opt to be supported by an app for commissioning and operation.
