How Mouvex Pumps Work: A Detailed Breakdown

 

Mouvex pumps operate using eccentric disc technology, a unique pumping mechanism that ensures high efficiency, gentle fluid handling, and exceptional product recovery. Unlike traditional positive displacement pumps, which rely on gears, lobes, or diaphragms, Mouvex pumps use a single eccentric disc that moves within a cylindrical chamber.

This design creates a highly efficient and leak-free pumping action, making them ideal for industries requiring precision, hygiene, and product integrity.

💭Understanding Eccentric Disc Technology

At the core of a Mouvex pump is a disc mounted on an eccentric shaft (a slightly off-centre shaft). This disc does not rotate like an impeller or move in a linear motion like a piston. Instead, it follows an eccentric motion that generates a series of expanding and contracting chambers inside the pump cylinder.

Step-by-Step Working Principle:

  1. Fluid Intake:
    • As the disc moves, it creates vacuum pockets inside the chamber, drawing in fluid from the suction side.
    • This vacuum effect allows self-priming, even in dry conditions or when handling medium viscosities below 10,000cP.
  2. Fluid Transfer:
    • The eccentric movement of the disc progressively pushes the fluid through the chamber without pulsation or turbulence.
    • The fluid moves smoothly through the pump with minimal shear stress, preserving product integrity—critical for sensitive applications like dairy, pharmaceuticals, and cosmetics.
  3. Fluid Discharge:
    • As the chambers contract, they force the liquid forward toward the discharge outlet.
    • The movement creates consistent volumetric efficiency, meaning each cycle transfers a precise amount of fluid regardless of pressure changes.

✨Key Features of Mouvex Pumps & How They Work

  1. Seal-less Design – Prevents Leaks and Contamination

Unlike traditional pumps that use mechanical seals, Mouvex pumps feature a seal-less design. Instead of relying on dynamic seals that can wear down over time and cause leaks, Mouvex pumps use:

  • A mechanical, leak-free containment system that isolates the pump’s fluid chamber from the external environment.
  • This eliminates the risk of contamination, making the pumps ideal for hygienic industries like food, pharmaceuticals, and chemicals.

 

  1. Self-Priming – Can Run Dry for Short Periods Without Damage

Mouvex pumps are naturally self-priming, meaning they can draw liquid into the system without needing pre-filling. This is due to:

  • Their ability to create a vacuum inside the pump chamber, pulling in fluid even when starting from dry conditions.
  • Unlike centrifugal pumps, which require a flooded suction line, Mouvex pumps can run dry temporarily without overheating or damaging components.

✅ Benefit: Reduces downtime and eliminates the need for external priming equipment.

  1. Constant Flow Rate – Unaffected by Pressure Fluctuations

One of the standout features of Mouvex pumps is their constant flow rate, which remains stable even when there are fluctuations in:

  • Back pressure from process piping
  • Viscosity changes in the pumped fluid
  • Variable fluid levels in tanks and containers

This is achieved through the eccentric disc’s design, which ensures:

  • Chamber volume remains consistent throughout the pumping cycle.
  • No internal slip (unlike gear or lobe pumps, which can experience efficiency losses due to slippage at high pressures).

✅ Benefit: Guarantees precise fluid metering and accurate dosing in critical applications.

  1. Hygienic and CIP/SIP-Compatible – Meets Stringent Industry Standards

Mouvex pumps are fully compliant with industry standards like:

  • 3-A Sanitary Standards (for dairy and food processing)
  • EHEDG Certification (for hygienic design)
  • FDA & USP Class VI Approvals (for pharmaceutical applications)

Their smooth internal surfaces and seal-less construction make them ideal for CIP (Clean-in-Place) and SIP (Sterilise-in-Place) processes, ensuring:

    • No product retention inside the pump.
    • Easy cleaning and reduced downtime for sanitation.

✅ Benefit: Eliminates cross-contamination risks in sensitive production environments.

  1. High Suction Power – Ensures Optimal Product Recovery

Mouvex pumps excel in product recovery, retrieving up to 98% of the fluid from a pipeline due to their:

  • Near-perfect vacuum effect created by the eccentric disc motion.
  • Air/liquid interface technology pushes out any remaining product with minimal waste.

✅ Benefit: Maximises product yield, reducing waste and increasing profitability.

Why Choose Mouvex Pumps Over Other Pump Technologies?

💡Conclusion

Mouvex pumps stand out due to their eccentric disc technology, seal-less design, and superior product recovery capabilities. Their ability to self-prime, maintain a constant flow, and operate hygienically makes them a top choice for industries requiring efficiency, sustainability, and precision.
