Two new products from KSB

PUMPS, VALVES AND SERVICES specialist KSB has recently launched two new product series.

The first addition from the company is a series of future-proofed diaphragm valves for drinking water.

Through its subsidiary, SISTO Armaturen, KSB has launched the SISTO-16RGAMaXX diaphragm valve type series, featuring threaded sockets, a stainless steel body and a special drinking water diaphragm.

The body is made of EN 1.4409 stainless steel, a material that is particularly resistant to chlorinated water and suitable for drinking water. To keep the fluid handled clean, the body is designed without dead volume, preventing deposits in the valve. Nominal sizes range from Rp 1/2in- 3in.

The confined and supported diaphragm maximises service life and is designed for a pressure of 16 bar. It is made of high-quality elastomer (EPDM/W270) and meets the German Environment Agency’s requirements on plastics suitable for drinking water applications (KTW-BWGL). The valves cover a temperature range from -10 to +90°C. This means the type series is also highly suitable for thermal disinfection.

Since the threaded stems for actuating the valves are not in contact with the fluid handled, they will continue to deliver smooth operation, even after many years of use.

The second new launch is a fully automatic break tank package booster set for fire fighting applications.

The Hya-Duo D FL-R pressure booster system has been designed to conform with DIN 14462 and uses only one main firefighting pump to supply hydrants installed above floor or under floor with up to 192 cubic metres of fire-fighting water per hour.

The booster set is fitted with two fully redundant pumps, each with its own power and control circuit. The redundant control systems continuously monitor pressure switches and limit switches for broken wires and short circuits. Motor and dry running protection are disabled in the event of a fire, making sure the pumps do not stop before fire fighting ends. The master switch and valves are secured against unauthorised operation. If one of the pumps fails, the redundant control system takes over and starts up the second pump. This provides a high level of safety for the operator, the buildings to be protected and the infrastructure.

The break tank ensures that drinking and fire-fighting water are hygienically separated to EN 1717 type AB. The net tank volume meets the 3% rule stipulated in the standard.

Corrosion resistant pumps

The new corrosionresistant EOV centrifugal pump range from Crest Pumps gives users a performance increase of up to 15% whilst consuming up to 20% less power when compared to the previous ECC range. The EOV features an enhanced vane design that improves efficiencies by up to 35%, so that flow rates and discharge pressures are improved on each model. Designed using the latest numerical software and proven by extensive testing, the volute casing incorporates the optimum shape and cutwater clearances whilst the impeller has the perfect combination of number, depth and shape of vane for maximum efficiency. All components are machined from solid thermoplastics such as polypropylene or PVDF for added strength and consistency. The open impeller design allows for some passage of solids, while the improved hydraulic design ensures excellent performance in low NPSH applications as well as minimal mechanical vibrations, ensuring a longer life between service intervals.
