Innovative Design Enhancements
O‑Ring Seal Technology: The patented, retrofittable back-pull-out bracket seal houses grease between double O‑rings to eliminate chocolate migration and reduce slip hazards—also compatible with existing CHC pump brands via retrofit kits
Built-in Cleanability Features: Stainless steel construction and smooth internal surfaces support food-safety standards (EC 1935 compliance), while flush/suck-back grooves and drilled idler gears reduce product buildup and seizing
Thermal Management: Integrated head/bracket jackets allow chocolate liquefaction prior to startup to avoid damage to seals and ensure consistent product flow
Reduced Maintenance: O‑rings can be replaced with the pump mounted in place, grease nipples and relief fittings eliminate overpressure, and component kits simplify conversion and servicing
