Ampco AC216MD14T-S Pump End Only with Max Impeller — AC Series Sanitary Centrifugal Pump Head
The Ampco AC216MD14T-S is the pump end only from the AC Series sanitary centrifugal line, supplied with the maximum impeller diameter the 216 casing will accept. Because it ships without a motor, it is the practical choice when you already have a suitable 140TC frame motor on the shelf, when you are rebuilding a skid around existing drive equipment, or when a fluid end has simply reached the end of its service life and the rest of the assembly is still sound. Everything that touches product is 316L stainless steel, polished to a 32 Ra finish, so the wetted path stays clean, drainable, and easy to inspect.
Flow enters through a 2 in. Tri-Clamp inlet and leaves through a 1-1/2 in. Tri-Clamp discharge, with the oversized impeller giving you the top of the 216 performance envelope — useful head at 1750 RPM and considerably more at 3500 RPM. Sealing is handled by the Type D single external balanced mechanical seal, built with a carbon rotary face, stainless steel seat, and Buna elastomers, an arrangement that holds up well against acidic products and aggressive CIP chemistry. The threaded impeller nut and clamped stub shaft keep the rotating assembly stable while still allowing quick teardown for cleaning or seal replacement.
This pump end is at home well beyond any single industry. Dairies and creameries run it, but so do breweries and distilleries, juice and beverage bottlers, tomato and sauce processors, personal care and nutraceutical plants, and chemical operations moving detergents, rinse water, and mild acids. If your process needs gentle, high-volume liquid transfer through a hygienic stainless flow path, the AC216 platform covers it, and this configuration lets you build exactly the pump you need around the motor you already have.

Frequently Asked Questions
Q: Does the AC216MD14T-S include a motor or a baseplate?
No. This is the pump end only, so you receive the casing, backplate, impeller, stub shaft, seal, and adapter. You supply the 140TC frame motor and any base, cart, or legs your installation calls for.
Q: Can I fit this pump end to a motor I already own?
Yes, provided it is a standard 140TC C-face motor in good condition with a true shaft. Confirm shaft runout and face squareness before mounting, since a worn motor will shorten mechanical seal life no matter how new the pump end is.
Q: Why choose the maximum impeller version instead of a trimmed impeller?
The maximum impeller places you at the top of the 216 performance curve, which gives you headroom if system resistance increases later. If your duty point is well below that, the impeller can be trimmed down at any time, but you cannot add diameter back.
Q: How is the pump end cleaned in place?
The open impeller design, 32 Ra polished wetted surfaces, and Tri-Clamp connections allow full CIP circulation without disassembly. For validation or product changeover, the clamped casing comes apart in minutes for visual inspection.
Q: What routine spare parts should be kept on hand?
Most operations stock a seal repair kit, the casing gasket or O-ring, and the impeller nut O-ring. Those three items cover the overwhelming majority of unplanned shutdowns on this pump family.
