Marlen vacuum stuffing and pumping systems are able to handle whole muscle, sectioned, formed, and emulsified. Marlen equipment includes twin-piston vacuum stuffers and pumps, hoppers, extruders, transducer portioning systems, depositors, vacuum fillers, grinders, forming systems, volumetric portioners, open hoppers, vacuumizing combo hoppers, load assist hoppers, auger hoppers, and Marlen parts.
  • Simplicity; no digital controls
  • All the basics of a twin piston Marlen pump at a fraction of the cost
  • Small footprint and easily portable. Low profile design accommodates space constraints and heavy-duty casters provide smooth unit mobility
  • 10,000 lbs pumping capacity with a maximum of 250 psi pumping pressure
  • Marlen’s unique high-differential vacuum ensures maximum removal of entrapped air resulting in denser product, more accurate portion control, and longer shelf life
  • Patented, hydraulically-driven front valve delivers positive shifting for continuous, even product flow, and more accurate portion weight control
  • Twin-piston pumping system designed to gently deliver products to downstream processes. The zero-slip design maintains product integrity for products ranging from the highly abrasive to whole muscle. The system is gentle on your products and reduces wear on the unit, extending its life.
  • Hopper options include standard open top hopper to full vacuumizer hoppers with augers for load assist for complete versatility
  • Designed for easy operation & control
  • Externally-adjustable diffuser valve (Patented)
  • Push-button controls
  • Proven twin-piston design
  • Largest product openings
  • Zero-slip design eliminates product degradation
  • Minimal product damage and fewer cuts
  • Designed to reduce the need for downstream accumulators or bypass
  • Precise metered flow or constant pressure control
  • Built to USDA accepted standards
  • Smaller number of parts simplifies cleanup
