Low Energy Air Pump – Sanitary

LEAP stands for Low Energy Air Pump, a ground-breaking technology used to reduce energy consumption for businesses running Air-Operated Diaphragm Pumps, allowing them to save up to 70% on energy costs. LEAP has been designed to control the airflow through a Diaphragm Pump using innovative technology developed here in the UK.

What’s the difference between LEAP and a standard AODD Pump?

• Your Diaphragm Pump will start at a much lower air pressure, typically 0.2 bar compared with industry-standard AOD Pumps which start at 1.2 bar
• Operation is much smoother due to reduced friction in the pump’s centre section
• Users of LEAP could save up to 70% on energy consumption

This technology can be requested on purchase of your Diaphragm Pump, or it can be retrofitted to any Tapflo, as well as several of our competitors’ pumps, by simply swapping the centre section on your pump. Many businesses are looking to meet energy-saving targets, which Tapflo can support you with. There has been a significant increase in demand for this revolutionary technology as businesses release just how much money and energy they could save by switching to LEAP.

• Available on the complete range of Tapflo Air Operated Diaphragm Pumps
• Retro-fittable: Switching to low energy technology is as simple as switching the centre section of your Tapflo Diaphragm Pump to a LEAP centre section. This is also applicable to several of our competitors’ pumps.

• Ultra-Low starting pressure: 0.2 Bar (3psi)

• Reduced energy consumption: saving up to 70% using our Low Energy Diaphragm Pump

• 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 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 by 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 coreolis flow meter with pulse feedback into their system to provide real-time monitoring of flow to within an even greater degree of accuracy. Coreolis Flow Meters are NEVER used with diaphragm pumps as they are susceptible to pulsing flow. This is 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 10 bar, 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!
