Mouvex C Series Pumps

The Mouvex C Series eccentric disc pump is a self-priming volumetric positive displacement (PD) pump that utilizes its strong suction power and ability to run dry to gently—yet effectively—move product. The pump features a seal-free design, which helps lead to more uptime and longer production runs.

The C Series stainless steel models are ideal for sanitary applications. These pumps carry 3-A approval certification and are designed to meet EHEDG specifications.

Seal-Free Design

A seal-free pump means leak-free pump. Designed without mechanical seals, packing, or magnets, the C series eccentric disc pump eliminates leakage and reduces maintenance time.

CIP & SIP Abilities

The stainless steel version is designed to be flushed and cleaned in place (CIP) without disassembling. The high temperature (HT) version of the pump is designed to withstand continuous exposure to temperatures up to 302°F.

Low Shearing
  • Disc has an eccentric motion (driven by an eccentric shaft)
  • Each point of the disc has the same linear speed
  • Mouvex technology allows a flow rate with low linear speed
  • Self-priming with strong suction power
  • Dry run capability
  • Maintenance of the delivery/pressure performance over time due to automatic disc/cylinder adjustment
  • Pumps low and high viscosity products
  • Low linear speed
  • Outstanding volumetric efficiency
  • Pumped product constantly renewed
  • Output not affected by viscosity variation
