LEAP (Low Energy Air Pump) technology, is a breakthrough in energy saving for Air-Operated Diaphragm Pumps. Airflow through the Diaphragm Pump is controlled using innovative new technology, that was designed in the UK, that transforms the performance of the pump, reducing operating costs and helping businesses meet new energy guidelines set by the government.
Businesses using LEAP technology could save up to 70% on energy consumption.
Tapflo has found that there is an increasing demand for revolutionary low energy technology as pump users begin making efforts to meet energy-saving targets.
This technology can be retro-fitted to any Tapflo, Dellmeco & Almatec Air-Operated Diaphragm Pump or supplied as a complete pump for those joining the energy-saving revolution.
Designed in the UK, LEAP technology allows Diaphragm Pumps to begin operating at a much lower air pressure, typically 0.2 bar compared with industry-standard Diaphragm Pumps that begin operating at 1.2 bar. The technology at work here produces a smoother operation through which also reduces the pulsations in the output of the pump.
Drive Type | Electric, Pneumatic |
Flow Rate | up to 820 l/min |
Pressure | up to 16 Bar |
Material | Aluminium, Cast Iron, PE & PTFE, Stainless Steel AISI 316L |
Self-Priming | Yes |
Solids Handling | up to 100mm |
Viscosity | 0-200+ cSt |
Our LEAP technology reduces air consumption, saving energy and reducing operating costs.
The graph below shows fluid flow against the air pressure required when comparing a standard Air-Operated Diaphragm Pump against Tapflo’s Low Energy Air Pump (LEAP). As you can see, at 0.5 bar air pressure, the LEAP pump was able to produce approx. 27.5 l/min whereas the standard pump didn’t even start operating until it was supplied with 1.1 bar air pressure, and only produced 5 l/min. This demonstrates that standard Air-Operated Diaphragm Pumps require a lot of energy to simply overcome the resistance within the pump. The energy required to do this is a direct correlation to the pressure you have to put in. By reducing the air pressure required to operate you can significantly reduce the operating costs of the pump. To put this into monetary terms, Tapflo customer required a 2” pump to run continuously for 5 days a week, 48 weeks/year, producing 150 l/min @ 1 Bar operating pressure. Based on the British Compressed Air Society figures of between £0.01 to £0.03 to produce 1000 Litres of compressed air, a standard pump would cost an average of £1843.20 / year. By converting to the LEAP technology, the customer would save £652.64 / year per pump!

The valve is also balanced to prevent any issues associated with high-pressure applications.

Even during normal operating conditions, some parts of the pump will be subject to wear & tear. In order to avoid expensive breakdowns, we recommend having a few spare parts in stock. Depending on the severity of the operation and the importance of assuring continuous operation we offer three different spare part KITS, please check full PE & PTFE, Metal, Sanitary IOM manuals* for further instructions. Please keep in mind that Low Energy Air Pump KIT AIR differs from standard PE & PTFE, Metal or Sanitary pump*. NOTE! Even though the Control Module [97E] is not a subject to wear, remember to replace it in case of leakage through the muffler.
