Feed Pumps
√ ZEFRONPAL is a volumetric lobe pump designed for transferring delicate, dense or viscous fluids in the cosmetic, food and chemical industries.
√ Entirely made of AISI 316L stainless steel, with polished product-contact components free from stagnation zones, ensuring maximum hygiene and easy cleaning.
√ Elliptical rotors and scrapers made of certified food and cosmetic-grade materials, ideal for handling sensitive products without altering their quality.
√ Working chamber designed to ensure complete product discharge and total elimination of residues through simple rinsing, drastically reducing downtime and simplifying cleaning operations.
√ Welded CLAMP fittings and fully polished internal piping to facilitate product discharge and cleaning.
√ High performance and long-term reliability.
√ The special design of the scrapers allows bidirectional product transfer by simply reversing the rotation of the rotors.
√ Compact trolley-mounted configuration, easily integrable into existing production lines and equipped with gear motor and single-phase inverter.
√ Built-in inverter in electrical box, featuring speed control and flow reversal.
√ Extremely quiet operation performance.
