Pumps and Valves

A PL200 pump from Börger has solved a challenging sludge-cake application for South East Water. Designed with a Maintenance-in-Place (MIP) Radial Liner System, Börger’s PL200 replaced an auger-feed progressive-cavity sludge cake pump, located under an old centrifuge decanter at Arlington WwTW.

Adjacent to a Site of Special Scientific Interest (SSSI) in Shropshire, pumps made by Landia are ensuring that a farm can cope with huge volumes of excess water it has to contend with during severe downpours.

Burkert’s new ELEMENT system provides a complete systems approach, linking clean line valves, sensors, positioners and valve actuators in a simple architecture to solve total control loop processes. With unlimited modularity, ELEMENT saves processing time by offering total control solutions for media from slurries to steam, and from de-ionized water to hydrochloric acid.

According to mixing specialists Chemineer, the pressure on the water industry to reduce spiralling energy costs could see a major switch to Top-Entry Mixers, which are cutting bills by up to a staggering 85% compared to submersible mixers.

After nearly two weeks of intensive testing at the National Screens Evaluation Facility*, Eimco Water Technologies’ new Spiral Screen has achieved the best ever SCR results for a spiral sieve type screen.

Brownell has introduced a range of Ultra High Flow Performance Relief Valves with standard sizes of 25 mm to 200 mm. An unusual operating characteristic for this pressure relief valve is proportional decrease in back pressure after the relief valve has opened at the set pressure and increased flow is required.

Eimco Water Technologies’ proven Copa Cyclone is the true, water-powered, self-cleaning storm screen, which is virtually maintenance free.

Maintenance-In-Place Pumps made by Börger are successfully removing grit from Wessex Water’s Bristol sewage treatment works at Avonmouth.

Providing the highest fluid control performance in the smallest possible space, Burkert’s new Type 6650 sets a new standard for miniature solenoid valves employed in clinical, life science, analytical and fluid handling equipment. Suitable for use on vacuum up to 7-bar, and providing medium isolation for aggressive fluids, the direct-acting Type 6650 is just 4.5mm wide yet outperforms comparable 10mm and 16mm designs.

At what is believed to be first installation of its kind in the UK, Severn Trent Water is making energy savings from Chemineer Mixers which have Variable Speed Drive Inverters.
