Ampco CB+ series

Main Features

Ampco CB+ Series — The Brewing Industry’s Seal of Reliability

Designed exclusively for brewers, the Ampco CB+ Series** redefines sanitary pump performance when handling hot wort and other demanding fluids. Built upon the proven C Series foundation, the CB+ introduces a revolutionary internal seal design that keeps seal faces cooler, cleaner, and running longer — so you can focus on your craft, not on leaking pumps.

When pumping near-boiling wort, traditional external seals tend to flash, overheat, and wear prematurely. The CB+ internal seal solves this by staying fully submersed in product, providing continuous cooling and minimizing product buildup.

Key Advantages

• Optimized for Hot Wort Transfer – Internal seal stays submerged, preventing flashing and extending seal life.
• Sanitary Internal Seal Design – Reduces product buildup, ensures consistent hygiene, and simplifies maintenance.
• Self-Cleaning Action – Internal spring keeps solids agitated, preventing pooling and leakage.
• Superior Durability – Balanced seal faces handle pressure changes without sticking or premature wear.

Design Features

Hydraulically and Dimensionally Interchangeable – The CB+ pump matches existing C Series dimensions, requiring no piping changes or costly system modifications.

Easy Upgrades – Ampco offers two CB+ conversion kits to transform your existing pumps into CB+ performance:

• CB+1 Kit: Convert an Ampco AC+ pump by simply replacing the seal and backplate.
• CB+2 Kit: Convert Ampco AC or other C Series pumps with a full upgrade kit including **backplate, seal, stub shaft, collar, o-ring, impeller, and nut.
• Cost-Effective Solution – Upgrade performance without buying a new pump that costs twice as much.

Technical Highlights

• 316L stainless steel construction for exceptional corrosion resistance
• Fully CIP (Clean-In-Place) capable
• Multiple size options to fit any brewhouse requirement
