New Low Energy Diaphragm Pump

Low Energy Diaphragm Pump, saving energy and money for your business!

LEAP technology sold globally through the Tapflo network.

Tapflo UK is proud to announce that a series of intelligent, low energy Diaphragm Pumps have been introduced into the company’s pump portfolio. Low Energy Air Pump The LEAP Series is the high quality, reliable Tapflo Diaphragm Pump design, with the added benefit of being fitted with ingenious Low Energy Air Pump (LEAP) technology that has been developed by Tapflo UK’s Technical Director.

LEAP or ‘Low Energy Air Pump’ is a patented technology used in Diaphragm Pumps to reduce the operating air pressure by reducing internal losses and friction found in conventional Air-Operated Diaphragm Pumps. One way this has been achieved with a new design of air valve that doesn’t suffer from the same amount of friction as air valves in standard Diaphragm Pumps. LEAP technology was developed for an ultra-low flow, high-pressure application utilising an Air Operated Double Diaphragm Pump with an electric power pack.

Benefits of the Intelligent, Low Energy Diaphragm Pump

Energy Savings

The extensive testing procedure has shown that the largest amount of energy required by a pump is used to overcome the resistance created by the pump itself. Another major issue is found in the mid-port scenario, wherein the attempt to save energy by turning down the air pressure, to a much lower level, causes the pump to stall. The Low Energy Diaphragm Pump is able to start pumping at 0.2 bar without stalling. During the tests, LEAP® was already achieving flow rates of 70% of its maximum open-end flow before other pumps had even started. At 0.3 (4.5 Psi) bar a standard Tapflo T50 pump fitted with LEAP® was already pumping at over 25 L/min, all other Diaphragm Pumps that were tested failed to even start. To achieve the same flows and control other pumps required 1.2 bar pressure. Tests undertaken to measure the performance of a standard pump against the new LEAP® pump have resulted in an energy saving of up to 70%.

Additional Benefits

  • Ultra low-pressure operation resulting in reduced energy consumption.
  • Impossible to stall due to revolutionary control technology which completely prevents stalling.
  • A LEAP centre section can be retrofitted to any existing Tapflo Air Operated Diaphragm Pump, as well as a range of other Diaphragm Pumps without purchasing a whole new pump.
  • Reduced pulsations mean there is virtually no need for a Pulsation Dampener
  • Improved Lifespan due to the design of LEAP® which utilises seal-less air valve technology with significantly longer life expectancy over conventionally sealed valves.
  • Noise Reduction – Diaphragm Pumps are notorious for their noise pollution during operation, LEAP’s low air pressure operation results in less noise from the pump.
  • Simplified Maintenance – the main air valve can be changed in less than two minutes without the removal of the pump from the process line.
  • Simplified control due to an integral solenoid valve control which negates the need for an external pneumatic solenoid valve, reducing costs and simplifying control.
  • Electrical feedback – integral VFC output signal allows for external monitoring of pump strokes.
  • Batch Dispensing achieved using the integral VFC output and an external predetermining counter which can automatically stop the pump after the required volume has been dispensed.
  • LEAP Pumps can dry run, the pump monitors the frequency of the output pulses and can determine if the pump is running dry due to increased stroke rate.
  • Deadheading – monitoring the frequency of the output pulses from the pump you can determine if the pump has stalled due to decreased stroke rate.

Case Study

Let’s consider a case from on of our customers.

This customer’s manufacturing process requires the application of the pump to run all day for 5 days a week. This is for roughly 48 weeks of the year. The costs associated with running the pump were estimated to be significant, using a 2″ pump and a fluid flow of 150L/min at 1 Bar discharge were roughly £2133 each year.

Once LEAP technology was installed, the costs reduced to £1378 which would equal roughly £755 savings each year compared to a standard Diaphragm Pump.
