Pumps/Vacuum technology

Pumps/Vacuum technology Companies – Innovations – Products a traditional pump. Qdos CWT pumps offer outstanding chemical dosing accuracy in water treatment applications. The pumps introduce chemicals – including sodium hypochlorite for post-chlorination cycles – without the need to overdose, thus delivering consistently high accuracy for the life of the pump. Positive user feedback Among the pilot sites able to provide testimony is the San Luis Rey Water Reclamation Facility in Oceanside, California. The facility, which collects, treats and disposes of all of the city's sewage, favours the use of peristaltic pumps over diaphragm pumps for their ability to handle off gassing chemicals such as sodium hypochlorite. The installation of the Qdos CWT pump has enabled the site’s engineers to use peristaltic technology in an application where pressure spikes and off gassing affected more traditional pump types. Since installation the San Luis Rey facility has experienced a significant increase in pump life. The sealed CWT pumphead – which delivers accurate, linear and repeatable flow – is also highly safe as it minimises operator exposure to chemicals, while changeover is possible in less than a minute without the need for tools. Qdos CWT users can gain from further operational and environmental safety through leak detection software, failure alarms and fluid recovery capabilities that avoid chemical waste. user feedback that CWT will help to deliver operational efficiencies to a wide range of users. We look forward to introducing more of our customers to its benefits.” Like all pumps in the range, the Qdos CWT is available in a number of variants that provide different levels of control, from Manual, Remote and PROFIBUS, through to Universal (automatic and manual control) and Universal+ (automatic and manual control with configurable 4-20 mA input and output). The new Qdos CWT range offers flow rates from 0.1 to 500 ml/min, and up to 7 bar RMS pressure. Flow control is up to 5000:1 with ±1 % accuracy. To ensure suitability for industrial environments, the Qdos CWT features an IP66 NEMA 4X rated casing. A three year warranty is standard. Launching Qdos CWT for chemical metering in the industrial sector marks only the beginning, as plans are already afoot to help a myriad of other applications enjoy the benefits available.

Our objective was to design a technology that delivers all the benefits of a traditional pump but with significantly longer service life than traditional tube designs. It’s clear from early Industrial processes often require the pumping and transport of demanding liquids. Therefore, robust and reliable pump systems are essential. They come into direct contact with media and play an important role in a variety of production processes. For extreme conditions, such as use in potentially explosive environments or pumping chemically aggressive and hot media, pumps must meet special industryspecific specifications and standards. Vogelsang GmbH & Co. KG from Essen (Oldenburg) is launching two new pump series to meet the high demands of industrial use: The EP series and VY series. The rotary lobe pumps of both series are made of a flow-optimized one-piece housing and are therefore particularly efficient. They reliably convey thin-bodied as well as highly viscous, 64 PROCESS TECHNOLOGY & COMPONENTS 2022

Pumps/Vacuum technology Companies – Innovations – Products pure and solids-containing media at temperatures of up to 200 °C. The pumps are ATEX and TA-Luft compliant and thus suited for use in highly demanding areas such as the oil, gas and chemical industries. Thanks to increased efficiency and added seal versatility, Vogelsang is able to open up new areas of application for its proven pump technology. As the inventor of the elastomer-coated rotary lobe pump in 1970, Vogelsang has been for decades one of the world's leading companies in the field of pumps. rates the gearbox and the pump chamber, ensuring that in the event of a leak, liquid will drain out rather than entering the gearbox. The Air- Gap also protects the gearbox when pumping hot media. Seal versatility for increased flexibility A variety of different sealing systems can be used in the housing of the new pump series depending on the industry-specific standard and requirement. In addition to the Vogelsang Quality-Cartridge, a completely pre-assembled mechanical seal in a cartridge design, further special mechanical seals are available for the EP and VY series. Vogelsang worked with leading manufactures to develop this CoX-Cartridge and offer the right solution for a variety of applications, from use in oil and sugar production, to conveying hot, chemically demanding media or latex paints. The seal's robust design also makes it suited for high-pressure use. The new pump series can also be equipped with mechanical seals according to API 682 if required. Fig. 2: Exploded view EP series: A high-performance gearbox allows for a maximum pressure output of up to 18 bar. VY series: A highly efficient all-rounder VY series rotary lobe pumps are based on Vogelsang's proven VX series. Different seals can be used in a variety of ways in the new housing depending on industry-specific standards and requirements. The versatility of the VY series makes it suitable for use in the chemical industry, as well as in the paper and textile sectors. The performance spectrum ranges from 1 m³/h to 120 m³/h at a maximum pressure of 10 bar. Integrated sensors provide all-important information about the pump's operating status. The VY series is also available with axial and radial wear protection for media with abrasive components. Fig. 1: The versatility of Vogelsang's new pump series makes them suitable for a wide range of applications. The EP series for extreme conditions and high-pressure performance The EP series is designed for extreme conditions and permanently high pressures. Its high-performance gearbox allows for a constant pressure output of up to 18 bar, making it unique on the market today. The pumps of the EP series consist of a one-piece housing made from either cast iron or stainless steel. Helical gears in the gearbox ensure smooth performance and reduce noise emissions. Pulsation-free transferring reduces wear on the adjacent pipeline to a minimum. The performance spectrum ranges from 1 m³/h to 120 m³/h at a maximum pressure of 18 bar. The free ball passage is 40 mm. The high-pressure performance and temperature limit of 200 °C along with its seal versatility make the EP Series suitable for applications for which companies previously used screw, gear and progressing cavity pumps. These include the oil and gas sector, tank farms, the petrochemical industry and the production of paints and varnishes, paper, glue and sugar. Rotary lobe pumps save more space and are more energy-efficient and service-friendly than other positive displacement pumps. Vogelsang has additionally equipped its EP series with an AirGap for increased operational reliability. This gap atmospherically sepa- Fig. 3: The performance spectrum of the VY series ranges from 1 m³/h to 120 m³/h at a maximum pressure of 10 bar. Service-friendly assembly and cleaning For increased ease of service, both pump series feature a quick connection in addition to a variety of seal options. Thanks to this, pipelines can be connected to pumps in a matter of minutes, thus minimising time, effort and costs for installation and conversion. Maintaining the pumps is also quick and easy. The Quick-Service cover allows access to all internal components. As a result wear parts can be replaced quickly without removing the pump from the pipeline. When designing the EP and VY series pumps, our engineers placed significant importance on easy cleaning. The pumps can be rinsed and disinfected according to PROCESS TECHNOLOGY & COMPONENTS 2022 65
