Non-contacting Ultrasonic Pumping Station Flow Measurement Saves Money for Dwr Cymru Welsh Water

by Pulsar Process Measurement Ltd  (Feb. 26, 2014)

Dwr Cymru Welsh Water has benefitted from the unique 'Pumped Volume' feature built into Pulsar's Quantum 2 Pump Station Controller; identifying a flow problem within a pumping station network without the need for expensive Magflow meters. Once the issue was resolved, pumped volume through one of the stations was reduced by 88% , ...

Process optimisation for solvent salvaging from sludge case study

by AVA- Huep GmbH u. Co. KG  (Apr. 14, 2014)

Manufacturers of painl removers are now obliged to take back used and contaminated paint remover due to environmental laws and market pressure. AVA supplies thermal vertical evaporation plants in order to reduce the disposal costs created by this and to salvage the solvents contained in the sludge. This offers the advantage that the contaminated ...

Pumps as turbines (PATs) in water distribution networks affected by intermittent service

by IWA Publishing  (Mar. 26, 2014)

A hydraulic model was developed in order to evaluate the potential energy recovery from the use of centrifugal pumps as turbines (PATs) in a water distribution network characterized by the presence of private tanks. The model integrates the Global Gradient Algorithm (GGA), with a pressure-driven model that permits a more realistic representation ...

Deep soil mixing shoring system to construct a 60 MGD, 40 foot deep wastewater pumping station

by Geo-Con, Inc.  (Mar. 25, 2014)

The City of San Mateo, CA operates three wastewater pumping stations on a 80' wide lot located in a residential area near San Francisco Bay. The age of the stations range from 12 to 50 years, the stations have difficulty pumping peak wet weather flows, and have structural and maintenance problems. For these reasons, a new station was proposed to ...

Vials & Syringes

Vials: A small bottle that contains a drug (especially a sealed sterile container for injection by needle) A glass or plastic vessel used for storing drinks or other liquids; typically cylindrical without handles and with a narrow neck that can be plugged or capped. Plastic vials can have other closure systems, such as ...

What is a slurry pump

Talking about slurry pump, we see slurry first then next is pump, so let’s start with slurry. Slurry is a kind of liquid with solids, mostly its specific gravities greater than 1. The solids size may vary from a few micrometers, often referred to as microns, up to hundreds of millimeters and the solids may settle below a ...

Gland packing seal replacement requirements

Gland packing seal requires continuous liquid lubrication and cooling between the rotating shaft shaft sleeve and the compressed packing, to prevent over heating due to the friction. The slurry is not a suitable liquid to provide this function, as the particles would very quickly wear through the protective ...

Effects of Slurry pump expeller

Expeller not only with sealing effect, but also can serve to reduce the axial force. The axial force in the slurry pump is mainly caused by the liquid pressure acting on the impeller and the rotating part of the composition of gravity. So it is easy to know, in the same identical performance parameters, slurry pump axial force is stronger ...
