Eccentric Disc Pump vs. Progressive Cavity Pump

by Christine Nunez | oct. 23, 2024

How do Mouvex Eccentric Disc Pumps compare to Progressive Cavity Pumps? While progressive cavity pumps are extremely low shear and ideally suited for shear-sensitive materials, these pumps lack the ability to fully recover products, self-prime and run dry. Additionally, the design of progressive cavity pumps often includes complex internal components, making cleaning and maintenance procedures labor-intensive and time-consuming, resulting in extended downtime and decreased operational efficiency.

To combat this, Mouvex Seal-less Eccentric Disc Pump offers similar benefits as a Progressive Cavity Pump but resolves a lot of the drawbacks with its unique design.

Mouvex Seal-less Eccentric Disc Pump capabilities include:

  • Shear sensitive (low shear) – extremely gentle, pulse-free flow to protect shear-sensitive products.
  • Seal-less – the unique seal-less design features a multi-layer bellows in stainless steel that ensures durability, safety and product containment. There is no mechanical seal or bushing to be in contact with the product, reducing leak-points, reducing maintenance, and ultimately increasing safety.
  • Consistent/constant performance – pulse-free, slip-free, and low-shear even flow in varying viscosities and back pressure conditions.
  • Run dry capability – the Mouvex eccentric disc pump can run dry for up to five minutes without causing any damage to the pump or process.
  • Product recovery – the eccentric disc design delivers high suction vacuum and high discharge pressure to self-prime the pump and fully strip the production line, minimizing product waste and dramatically improving production yield.
  • Line stripping (cleaning between batches) – with its clean-in-place (CIP) design/capability, the same pump can be used for different batches, eliminating product containment during changeovers as well as making the process easy.
  • All stainless-steel construction – with stainless steel as the standard material, there are no opportunities for rust and adds additional benefits for easy chemical cleanup.
  • Easy maintenance – with no mechanical seals or timing gears and only two (2) wear parts, the Mouvex eccentric disc design is very cost-effective and easy to maintain.
