  The oil-free EDP 80 - 400 vacuum pumps from Edwards have a vertical design, so the pump prevents the accumulation of particles and thus ensures long-lasting performance. Available in pumping speed classes 80, 160, 250 and 400 m³/h, these dry pumps minimise the risk of process and waste water contamination. www.edwardsvacuum.com Read the full article

  Blackmer developed a series of Sliding Vane Magnetic Drive Pumps named Magnes. This pump is dry running, pumping fluids with solids, handling of fluids with entrained vapors and poor inlet conditions, and inflexible pump operating range – while also delivering technically superior handling of hazardous chemicals in severe-duty applications. These pumps are positive displacement rotary vane pumps that use a magnetic drive without dynamic seals, providing a leak-free pumping solution for difficult-to-seal, expensive, valuable, dangerous and hazardous liquids. With this rotary vane magnetic drive pump design, these pumps combine the leak-free benefits of a magnetic drive pump with the numerous advantages of sliding vane technology – including self-priming, line-stripping, product recovery, indefinite dry-run capability, solids handling, thin/thick viscosity flexibility, easy maintenance, low to zero NPSHr, 70 % to 90 % pump efficiencies, and full-curve operational flexibility. Available in a 3-inch model (a 4-inch model will be available in January 2021) in both ductile iron and stainless-steel construction, Magnes Series pumps feature a non-metallic, proprietary composite containment shell that provides the coupling strength of a thin wall metallic shell and the reliability of an eddy-current-free design. blackmer.com Read the full article

The Liquiphant is used in storage tanks and pipelines for level measurement of any liquids. The all-rounder also works where other measuring principles reach their limits due to conductivity, flows or air bubbles. The Liquiphant has already been developed according to IEC 61508 and the “Safety by design” principle and is therefore designed for use in SIL2 and SIL3 applications. More Industry 4.0 In the technology roadmap to “Process sensors 4.0” NAMUR demands that a second, mobile way to communicate with the sensor must be opened and that the sensor provides information for preventive maintenance and process optimization. Furthermore product information such as manuals or certificates must be available on site at all times. Operators can now communicate with the Liquiphant and the SmartBlue App from Endress+Hauser. The app provides access to all product and diagnostic data. Especially in hard-to-reach areas, where scaffolding has to be provided for maintenance, this speeds up the inspection of systems considerably. The new Liquiphant displays the status of the level switch via LED or via the diagnostic function of Heartbeat Technology in the SmartBlue App. In addition verification via Heartbeat Technology enables complete documentation. The newly implemented SIL Wizard also guides the user through the recurring test in an uncomplicated manner. Read the full article
