Specific Additional Advantages of Eccentric Disc Pumps

When used in hygienic-manufacturing operations, the Mouvex eccentric disc pump serves first as the normal process pump, with the product-recovery capability coming as a bonus. For other pump styles, the product-recovery hardware, such as pigging systems, comes at a considerable cost premium and adds unnecessary complexity to the pumping operation. Specific additional advantages of eccentric disc pumps in product-recovery applications when compared to other product-recovery methods include:

  • Eccentric disc pumps can recover product from tank bottoms, inlet and outlet lines.
  • They can recover product from small-diameter lines where pigging is not possible.
  • They can recover product through ordinary valves, heat exchangers, magnetic traps, flow meters and other accessories found in the transfer line.
  • Product recovery with eccentric disc pumps is seamless as no line interruptions will occur between normal production and the product-recovery phase.
  • For the majority of the product-recovery process, air mixing is not a concern as most of the product recovered by an eccentric disc pump comes in the form of a product plug with no air mixed in. A simple flow switch can be used to shut down the pump before the air purge reaches the product’s destination.

Conclusion

Reducing the operating costs in a manufacturing facility will be a front-of-mind concern for plant managers for the foreseeable future. Initially, cutting energy costs was a popular way to attack the problem, but the overall value of that approach to the manufacturer’s bottom line may have already been maximized. Operators of food and beverage, pharmaceutical and cosmetic manufacturing facilities that rely on hygienic systems would be wise to not only develop ways to optimize energy costs, but to also determine how much cost savings can be realized in targeted product recovery. In a large production operation, that can result in millions of dollars of savings per year.
