Sodium hypochlorite handling pump Watson-Marlow Bredel has launched its 520 Series peristaltic pump for sodium hypochlorite handling, which is aimed at the environmental industry. The combination of tube elements and pumphead design allows the 520 Series to be utilized in the accurate metering, dosing and transferring of sodium hypochlorite, often used in the purification of

wastewater and the disinfection of drinking water.
According to Watson-Marlow Bredel, entrained gas, often generated by the hypo, is pumped easily and can eliminate the vapor locking, which can prevent many pumps from functioning properly. The 520 Series contain fluid within the tube at all times and never allows the sodium hypochlorite to come into contact with the pump mechanism which can ensure accurate fluid handling.

Turbomolecular pump for vacuum systems The EXT406PX, a turbomolecular pump for laboratory vacuum systems, has been launched by Edwards. The pump is reportedly the first pump of its kind that combines turbomolecular and drag stages with a fluid dynamic stage, making it possible to achieve the same gas flow using a smaller backing pump. Edward’s EXT406PX was developed for use in combination with a backing pump of smaller capacity, resulting in a vacuum system which consumes less power than comparable systems. The company says that incorporating the pump in a system makes the system capable of withstanding high
backing pressures even with continuous gas loads at the main inlet. “Our patented EXT406PX turbo pump means customers are able to reduce the size of the backing pump used in the system, without compromising the performance of the turbo pumped system. [This results in] a reduced vacuum package size and lower running costs,” says Ian Olsen, Edwards product manager for scientific turbo pumps. The pump is available in two ranges. The ISO and CF 160 have Nitrogen (N2) pumping speeds of 400 litres/second (N2) and the ISO and CF 100
have N2 pumping speeds of 310 litres/second (340 litres/ second for He). They can sustain normal operation at a backing pressure of up to 17 mbar. Other features include an optional inlet port, which, when correctly employed, can offer additional steady-state pumping speeds up to 24 m³ / h-1 at a pressure up to 4 mbar.

in sewage treatment plants, hotel kitchens, industrial car washers and large scale aquariums.
The ET series of pumps are designed to provide a low pressure, constant flow, oil-free air source for environmental or industrial use. The pumps also incorporate a noise adsorbing double damping system within the alloy casing, which can create a quiet 8

The fully automatic Hya-Eco VP with two to three high-pressure pumps.
KSB’s new pressure boosting package units of the Hya-Eco VP and Hya-Eco K series are equipped with two to three high-pressure pumps. The units offer two different control modes to meet user requirements. The pumps either start one after the other in cascade (Hya Eco K) or operate at variable speed (Hya-Eco VP) by means of a frequency inverter in order to ensure a constant system discharge pressure. The pumps feature corrosionresistant hydraulics and a pressure boundary designed so as to keep entrapped air away from the mechanical seal. According to KSB, this prevents dry running and increases the pumps’ service life. Hya-Eco units are used for drinking, service, fire-fighting and cooling water supply. The units can be used in residential and industrial buildings, hospitals, office buildings, hotels and department stores. The units meet the requirements of the French drinking water regulations ACS, which are among the most stringent in Europe. WORLD PUMPS April 2008
