Europe’s Largest Diaphragm Pump Manufacturer
Our LEAP (Low Energy Air Pump) technology is an energy-saving breakthrough for Air-Operated Diaphragm Pumps. This patented technology reduces the minimum operating pressure of your Diaphragm Pump by reducing internal losses and friction found in conventional AODD Pumps.
This technology uses an indirect system to detect the diaphragm shaft’s position and automatically control its movement.
Available across our range of Plastic, Metal and Sanitary AODD Pumps, this can save up to 70% on energy consumption by operating at a much lower air pressure (typically 0.2 Bar), compared to industry-standard pumps.
Typical applications for the Sanitary version include:
| Specification | TC80 – TC425 |
|---|---|
| Max Capacity (l/min) | 570 |
| Volume per stroke (ml) | 2,300 |
| Max Discharge (Bar) | 8 |
| Max Suction Lift Dry (m) | 4 |
| Max Suction Lift Wet (m) | 9 |
| Max Solids (ø in mm) | 15 |
| Max Temp (°C) | 110 |
Our LEAP technology reduces air consumption, helping to lower energy use and operating costs. Compared to a standard Air-Operated Diaphragm Pump, it delivers higher flow at lower pressures. For example, LEAP produces around 27.5 l/min at 0.5 bar, whereas a standard pump begins operating at about 1.1 bar and delivers roughly 5 l/min.
This difference shows how standard pumps require more energy to overcome internal resistance, with energy demand directly linked to input pressure. By operating efficiently at lower pressures, LEAP technology offers a more cost-effective solution.
In a typical application, running a 2” pump continuously at 150 l/min and 1 bar, a standard pump may cost around £1,843 per year in compressed air. Switching to LEAP could save approximately £650 per pump annually. (Figures from 2020)

What LEAP Technology is, how it works, and how it can save energy and money for your business.
Utilising LEAP Technology in the beverage sector for efficient fluid transfer to break tanks.
The Sanitary LEAP® pump combines Tapflo’s patented Low Energy Air Pump technology (LEAP®) with sanitary design standards to meet the strict hygiene requirements of Food, Beverage, Pharmaceutical, and Cosmetic industries. It features smooth internal surfaces for easy cleaning, a lubrication-free air distribution system, maintenance-free ball check valves, visual inspection of wetted parts for hygiene assurance, as well as CIP and SIP compatibility.
By reducing the minimum operating air pressure through internal loss and friction reduction, LEAP® cuts energy costs, helping sustainable production, enabling quieter, smoother operation (critical in hygienic environments), allows precise batch dispensing for consistent product quality, supports dry running without damaging the pump, and provides electrical feedback for easy automation and process control.
The wetted parts are made from sanitary-approved materials such as PTFE (virgin and with white back), EPDM and white EPDM as well as White NBR. These materials meet hygienic and safety standards and ensure no contamination of the product.
Yes. The pump design features few components, making maintenance fast and simple, with visual access to wetted parts to monitor cleanliness. Additionally, it features removable manifold clamps and screws for full disassembly and cleaning, and is fully compatible with CIP and SIP cleaning protocols.
Yes. LEAP® technology is designed to be retrofit-ready on existing Tapflo Sanitary AODD Pumps, enabling energy savings without a full system replacement.
Ideal for hygienic industries such as Dairy products (milk, yogurt, cream cheese), Grocery (ketchup, mayonnaise, tomato products, mustard), Beverages (juices, flavours, colouring agents), Bakery (dough, ingredients), Brewery (beer, wort, flavours), and Cosmetics & Personal Care (soaps, toothpaste, shampoo, perfumes).
