Pumps/Vacuum technology

Pumps/Vacuum technology Companies – Innovations – Products the CIP (Cleaning in Place) and SIP (Sterilisation in Place) cleaning procedures. The housing design also reduces dead space to a minimum, thus preventing liquids from accumulating in gaps or uneven surfaces. The EP and VY series offer industrial companies a highly efficient, flow-optimised and service-friendly pump technology suited for a wide range of demanding applications. Vogelsang GmbH & Co. KG Holthoege 10-14 49632 Essen (Oldenburg), Germany Phone +49 (0)5434 83-0 germany@vogelsang.info www.vogelsang.info From positive displacement pump system provider to specialist for handling complex media: NETZSCH Pumps & Systems enters the peristaltic market with the PERIPRO pump NETZSCH Pumps & Systems, the internationally active pump manufacturer from Bavaria, expands its positive displacement pump offering with the PERIPRO peristaltic pump. The PERIPRO ® peristaltic pump delivers large flow rates at a wide range of pressures. This means that the system provider for positive displacement pumps is now establishing itself as a specialist for pumping complex and difficult media. 90 % less lubricant than other peristaltic pumps and enable an extremely high metering accuracy. Depending on the field of application, the PERIPRO is offered in different versions to optimally cover the needs of customers.

Existing installations utilized screw pumps from various manufactures. Shaft sealing was done with mechanical seals or gland packing, both with steam quench. Main objectives of the new project were to improve availability of the pumps and to substantially reduce OPEX, especially those associated with maintenance. Additionally, the solution should be up to date in regards to current and foreseeable health and safety and environmental regulations. Klaus Union provided engineering and technical studies, comparing different solutions for the customer’s application. The PERIPRO peristaltic pumps from NETZSCH in hygienic design or also in industrial design The PERIPRO expands the NETZSCH pump portfolio with its characteristics as particularly robust and powerful pump that can easily handle viscous and abrasive media even at high pressures. These pumps have a long operating life, are easy to use, and enable 30 % energy savings as compared to other hose pumps due to their inventive design. These peristaltic pumps have very few wear parts. There are no valves or mechanical seals; the only wear part is the hose, characterized by remarkable durability due to an innovative manufacturing process. In addition, the pumps are insensitive to dry running, require Operating data Fluid: Bitumen/Aspahlt Flow Rate: 135 m³/h (594 gpm) Temperature: 140 ... 180 °C (284 ... 356 °F) Differential Pressure: 12 bar (174 psi) 66 PROCESS TECHNOLOGY & COMPONENTS 2022

The satisfied customer has started a project to replace his existing old pumps with Klaus Union magnet drive twin screw pumps. The thought process All existing Bitumen pumps in that refinery were classified as “bad actors” due to high leakage rates and short seal lifetimes. Based on this existing experience, the following iterations were taken during the preengineering phase of the project: – Bitumen/Asphalt is prone to cracking when it reaches the atmosphere. Accordingly, seals should be executed with API Plan 62 (steam quench), requiring additional utilities. Even under ideal conditions an API Plan 62 does not prevent leakage to the atmosphere, making the pump installation always a dirty spot. Additionally, Steam supply may sometimes fail or be outside permissible range, leading to regular seal damage and pump downtime. – Double acting mechanical seal with an API Plan 53 or 54 system were evaluated next. An API Plan 53/54 system does not have the same problems as a steam quench as it provides a stable, pressurized barrier system preventing any Bitumen leakage to the outside. However, with a Bitumen/Asphalt application the seal supply system would need to cover both sufficient pre-heating to prevent stocking of the product, as well as sufficient cooling capacity to prevent overheating of the barrier fluid system. This means to ensure a stable operation numerous signals (temperature, pressure, etc.) and utilities (cooling water or energy for an air cooler, nitrogen for API Plan 53, etc.) are required, making this an expensive investment if not for the pump, then for the site. – Based on existing experience in handling difficult to seal and even toxic liquid, Klaus Union recommended a solution for the customer’s needs, by executing the pump with seal less magnetic coupling system from Klaus Union. The magnetic coupling is equipped with a non-metallic isolation shell, to avoid eddy current losses and provides a pressure rating of 25 bar for the complete pump. The pump only requires two signals – a temperature transmitter on the isolation shell to provide a startup interlock to ensure proper pre-heating temperature, and a PT100 on the casing to ensure the maximum temperature for the pump is not exceeded. Otherwise no additional accessories are required, and the product is not contaminated by any auxiliary fluids. The benefits – Eliminating „bad actor“ no. 1: mechanical seal – Maintenance and Leak-free magnetic coupling, eliminating costs for steam quench or API Plan 53/54 Systems – Robust API 676 compliant pump design to increase MTBF – Pump design adaptive to customer requirements – Continuously high pump efficiency, even at large variations of pressure and viscosity – No timing required after maintenance, decreasing downtimes for maintenance – High standardization for fast availability of spares, many available directly from stock – Modular system for pump and magnetic coupling can be adapted to customer‘s and application requirements The SLM DSP-2C provides a simpler, cleaner solution to the customer’s needs for highly reliable and highly efficient positive displacement pumps.
