Every minute of processing downtime costs money, and with maintenance teams stretched thin, lost hours are a luxury most processors can't afford. Traditional air-operated double-diaphragm (AODD) pumps can take two hours or more to strip down for cleaning, so every minute of maintenance time reduced represents added capacity and productivity for the team.
The Flotronic® One-Nut® AODD+™ pump from Unibloc® Hygienic Technologies does that two-hour job in just 15 minutes—cutting downtime by up to 85% and freeing scarce labor for other higher-value tasks.
Wondering how that’s possible? The new Flotronic AODD+ Sanitary Solutions Applications Sourcebook captures real-world case studies showing how manufacturers worldwide have turned that time savings into major cost reductions, improved food safety, and greater operational efficiency.
Why the One-Nut AODD+ is different
Traditional AODD pumps can take hours to clean, require full disassembly, and often leave behind significant product waste. The Flotronic One-Nut pump turns that model on its head. With just a single nut, maintenance and diaphragm replacement can be done in 15 minutes compared to two hours or more for conventional pumps.

The advantages extend well beyond speed:
- In-line clean-in-place (CIP) capability at up to 7 bar without bypassing the pump.
- Self-draining design, leaving 60% less product in the pump versus competitors.
- Tool-free options on models like the Flotronic® Good Food pump, streamlining sanitation. This specialized model within the One-Nut line is designed specifically for food processors who require hygienic performance with tool-free cleaning and the ability to handle high-viscosity or shear-sensitive products.
- Capability to move high-viscosity products (up to 100,000 cP), making them versatile across industries.
Flotronic pumps are manufactured to the specific license requirements of 3-A SSI and EHEDG. Pump bodies begin as a single piece of stainless steel, relying on 316L stainless for all wetted metal parts, to ensure compliance with FDA standards.
In short, the Flotronic One-Nut pump from Unibloc simplifies maintenance, improves product recovery, and minimizes risk—all critical to lowering Total Cost of Ownership (TCO).
Real-world applications provide a window into versatility.
The strength of the Flotronic Sourcebook lies in its industry-specific applications. The stories inside demonstrate how processors in countries around the world are using One-Nut technology to solve critical challenges.
- Food Safety Secured: A Japanese kimchi manufacturer faced recurring contamination from stainless-steel particles in their rotary pumps. Switching to a Flotronic pump eliminated contamination incidents entirely and reduced bacteria counts in their product to zero.
- Chocolate Made Easy: A French confectionery needed to transfer chocolate with whole almonds—a tough application for most pumps. The Flotronic Good Food pump handled the 6,000 cP viscosity with large manifolds that let the almonds pass intact, preserving product quality while enabling rapid tool-free cleaning.
- Pharmaceutical Precision: In Belgium, a medical silicone processor used the Flotronic Barrel Unloading System to achieve 99% product recovery while ensuring full hygienic compliance. The CIP-ready design eliminated lengthy changeovers between production batches.
- Chemical Reliability: An automotive manufacturer in the UK needed to safely handle sulfuric acid. A Flotronic polypropylene-bodied AODD pump with PTFE diaphragms has run for years with minimal maintenance, providing confidence in aggressive applications.

Each case study in the sourcebook includes pump specifications, process details, and quantified results, to help illustrate how the Flotronic pump works across applications.
Documented cost savings.
Downtime, contamination, and maintenance costs all erode profitability. The Flotronic One-Nut pump directly addresses these pain points. Documented savings include:
- $55,000 saved over three years in a zinc oxide slurry application by extending mean time between failures.
- 60% less product waste, thanks to the pump’s self-draining design.
- Zero contamination incidents in food production, preventing costly recalls and waste.
These results align with our company’s mission and commitment to our customers: engineered to outperform, built to outlast, and designed to save more.
