Product Showcase WWT PUMP AND VALVE SUPPLEMENT 2018 17 What's new in the world of pumps and valves? WWT takes a look at the latest innovative products that are generating a buzz in the market OTT Hydromet: A turnkey solution for monitoring pumps as well as the environment The OTT Hydromet group has developed a complete solution that combines the efficient management of pumps with environmental protection. "By combining the latest sensor and communications technology, and by incorporating environmental impact, we are able to install bespoke monitoring solutions," says OTT's Matthew Ellison. "Automatic alarm capability enables rapid response to changing conditions for applications in abstraction, irrigation, surface water flooding and sewer flooding, ensuring complete user confidence." The new systems monitor pump performance, providing operators with remote access to pump sensors as well as optional catchment environmental sensors. Parameters such as water level, rainfall, wind, temperature and humidity, along with water quality indicators for turbidity, dissolved oxygen, pH and conductivity, can all be viewed in real time. By selecting from a range of communications methods, including radio, satellite and cellular technologies, OTT's engineers are able to configure systems that best meet each site's communications requirements while minimising operational costs. By monitoring both the pump network and the environment, OTT's systems provide users with real-time access across the catchment without having to visit the site – which saves time and money. Quick and easy to install, the systems maximise pump efficiency, minimise energy consumption and protect habitats. KSB mechanical seal range KSB Group will present its mechanical seal range, which now comprises more than 30 type series, at this year's IFAT trade fair in Munich in May. One of its key exhibits will be the 4EB series, a mechanical seal developed for large pumps handling drinking water and service water. The single mechanical seal in modular design is very compact; with the mechanical seal optimally matched to its installation space in the pump, wear is kept to a minimum, ensuring a long service life. The primary rings are made of silicon carbide as standard. For the mating rings, the user can choose between silicon carbide and carbon graphite. The O-rings are made of EPDM or FKM elastomers certified for drinking water. All metal components are manufactured from corrosion-resistant stainless steels, such as 1.4122 or 1.4571. A multispring arrangement provides the required preloading for the mechanical seal without coming into contact with the fluid handled. This protects the individual springs from contamination and leads to a longer overall seal life. When designing the 4EB seal, KSB Group's engineers attached great importance to straight- forward installation and removal. Assembly fixtures and fastening bolts are not required; the seal's modular design minimises downtime during maintenance inspections and prevents faulty reassembly. The mechanical seal is suitable for a dynamic operating pressure of up to 25 bar and a static operating pressure of up to 37.5 bar.
