Redesigned Mouvex® A Series Eccentric Disc Pump Offer Fluid-Handling Versatility

On the surface, it would not appear that products as varied as oil and natural gas, chemicals, and food and beverages would have much in common. But if you’re a manufacturer tasked with producing those types of products they have one major thing in common—all require pumping technology that can deliver the following features and benefits:

  • Self-priming capability
  • Ability to maintain constant flow rates regardless of changing system viscosity, temperature or pressure conditions
  • Ability to handle extremely high fluid temperatures (150ºC/302ºF for standard configurations and 250ºC/482ºF for high-temperature configurations)
  • Ability to handle solid particulates
  • Ability to dry-compress and line-strip
  • Limited dry-run capability
  • Ductile-iron construction with the ability to handle abrasive materials
  • Low-horsepower operation
  • Simple design
  • Ease of maintenance

With the supply of those operational characteristics in mind, more and more facility operators in the oil and gas, chemical, and food and beverage industries are becoming aware of the ability of positive displacement eccentric disc pump technology to meet their fluid-handling needs.

Eccentric disc pump design consists of a cylinder and pumping element that are mounted on an eccentric shaft. As the eccentric shaft rotates, the pumping element forms chambers within the cylinder, which increase in size at the intake port, drawing fluid into the pumping chamber. The fluid is then transported to the discharge port where the size of the pumping chamber is decreased. This action squeezes the fluid into the discharge piping. The result is a pumping technology that delivers shear-sensitive and gentle transfer of a wide array of fluid types.

Mouvex®, Auxerre, France, has been a leader in providing eccentric disc pump technology to many industries since 1906. Recently, the company redesigned its standard-setting A Series Eccentric Disc Pump family to better meet the challenges of today’s oil and gas, chemical, and food and beverage markets. Upgrades include the availability of ISO PN16/ANSI 150 flanges, ductile-iron construction and a choice of Mouvex or standardized mechanical seals. The redesigned pump has also doubled its maximum differential pressure from 5 bar (72 psi) to 10 bar (145 psi), which makes it ideal for use in the safe transfer of viscous, non-lubricating, volatile or delicate fluids that are found in a variety of industries.

To help Mouvex get its A Series pumps into the hands of its North American clients as quickly as possible, in September 2012 parent company Pump Solutions Group (PSG®), Oakbrook Terrace, IL, USA, of which Mouvex was a founding member in 2008, opened the new Euro-Center at its Grand Terrace, CA, USA, facility. The Euro-Center is a full-service ISO 9001-, ISO 14001- and ISO 18001-certified operation that provides application engineering, market support and after-sales support for all Mouvex pump models. Channel partners are also able to process purchase and part orders for Mouvex pumps, which helps decrease product lead-times and allows for expedited repair and transmission rebuilds.

We are always interested in hearing about any equipment-related successes you have had in any of your operations. If there are any recent instances where a positive displacement Mouvex® A Series Eccentric Disc Pump has helped optimize your fluid-handling performance in any industrial application, please send me an email at tom.zuckett@psgdover.com.
