LEAP (Low Energy Air Pump) technology is an energy-saving breakthrough for Air-Operated Diaphragm Pumps. Airflow through the Diaphragm Pump is controlled using innovative new technology designed in the UK, transforming the pump’s performance, 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 retrofitted 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, which also reduces the pulsations in the output of the pump.

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!

LEAP Flow Rate Comparison Graph

  • Available on the complete range of Tapflo Air Operated Diaphragm Pumps as well as Dellmeco & Almatec
  • Can be retro-fitted: To switch an existing Tapflo, Dellmeco or Almatec Air-Operated Diaphragm Pump over to LEAP, only the centre section needs replacing.
  • Ultra-Low starting pressure: 2 meters (3psi)
  • Reduced energy consumption: LEAP can achieve savings of up to 70% compared to standard Diaphragm Pumps
  • Impossible to stall (mid-port)
  • 24vdc starting signal (2.3w/1w) & Dry contact (VFC) feedback on completed strokes – provides control & feedback to the operator for preventive maintenance as well as performance monitoring such as:
  • Batch dispensing: Simply counting the strokes of the diaphragms and stopping the pump after the required volume has been dispensed.
  • Dry Running: By analysing the frequency of the pulses you can monitor whether the pump is dry-running or not. When the pump starts to dry run the frequency of the pulses will increase.
  • Dead Heading: When the frequency of the pulses slows down or stops this means that the pump has deadheaded, indicating a closed valve operation or a blockage in the pipework.
  • Flow Monitoring: Counting the frequency of the pulses can also be used to monitor the flow rate of the media in the process. The diaphragms displace a set amount per stroke; therefore multiplying the strokes by the volume displaced per stroke provides an accurate indication of flow. Or, indeed, in the case of one of our customers, wiring in a Coriolis flow meter with pulse feedback into their system to provide real-time monitoring of flow to within an even greater degree of accuracy. Coriolis Flow Meters are NEVER used with diaphragm pumps as they are susceptible to pulsing flow. This is a testament to the ability of the LEAP Pump to reduce the pulsing effect usually associated with traditional diaphragm pumps.
  • Easy to maintain – Air Valve can be replaced in under 2 minutes. Pump disassembly isn’t required!
  • Reduced pulsation – negates the need for a pulsation dampener in many instances!
  • EP Mode for high-pressure applications and start control: As standard, the unit is supplied with an internal pilot signal; however, should the unit be required to be used in a high-pressure application, in excess of 100 meters, i.e. Filter Press applications, the unit can be easily modified to use a lower pressure external pilot.
  • One seal design: reduced frictional losses
  • Noise reduction: lower air pressures reduces the noise of the pump
  • Control simplification: No need for an external pneumatic solenoid valve, reducing costs and simplifying control
  • Improved Life of main Air Valve: Tapflo have developed their own air valve for use with the LEAP technology using a lapped spool and sleeve construction. This provides a life expectancy in excess of 200 million cycles!
