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 include:
| Specification | TC 50 – TC 400 (HDPE & PTFE) | TC 70 – TC 420 (Metal) |
|---|---|---|
| Max Capacity (l/min) | 470 | 470 |
| Volume per stroke (ml) | 2300 | 2300 |
| Max Pressure (Bar) | 8 | 8 |
| Max Solids (ø in mm) | 15 | 15 |
| Max Suction Lift Dry (m) | 4 | 4 |
| Max Suction Lift Wet (m) | 9 | 9 |
| Max Temp PE (°C) | 70 | 80 (EPDM/NBR) |
| Max Temp PTFE (°C) | 100 | 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)

LEAP® (Low Energy Air Pump) is Tapflo’s patented innovation for AODD (Air Operated Double Diaphragm) Pumps. It allows the pump to operate at lower air pressures than conventional designs by reducing internal losses, minimising friction, and automatically detecting the diaphragm position via a unique indirect sensing system.
Conventional Air-Operated Diaphragm Pumps require higher air pressure to overcome start-up resistance. LEAP-equipped pumps can start and run at much lower air pressures, significantly reducing compressed air consumption, which is often one of the most energy-intensive resources in a plant. The result? Lower operating costs and reduced energy consumption.
LEAP® is available across multiple Tapflo Pump ranges, including Plastic AODD Pumps, Metal AODD Pumps, and Sanitary AODD Pumps. It is also retrofit-friendly, meaning existing Tapflo pumps can be upgraded with LEAP®.
These pumps can run dry without damage, operate quietly, and withstand blocked discharge lines. They provide accurate fluid delivery per cycle, integrate easily with control systems, and feature self-monitoring capabilities. With fewer moving parts and reduced friction, they also offer lower maintenance requirements and extended service life.
Yes. With electrical feedback and diaphragm position control, LEAP® enables precise dosing/batching, integration into automated process systems, and improved process monitoring.
In most cases, yes. LEAP® can be installed on compatible existing Tapflo Diaphragm Pumps, as well as on Dellmeco and Almatec pumps, allowing you to upgrade your current system to benefit from energy savings without replacing the entire pump.
