New TC Series – Intelligent diaphragm pumps from Tapflo

New TC Series - Intelligent diaphragm pumps

Tapflo is proud to announce that a series of Intelligent diaphragm pumps have been implemented into the company’s pump range portfolio.

New TC Series – Intelligent diaphragm pumps from Tapflo are fitted with ingenious LEAP® technology developed by Tapflo UK.

LEAP® or ‘Low Energy Air Pump’ is a patented technology used in AODD pumps to reduce the operating air pressure by reducing internal losses and friction found in conventional AODD pumps.

The LEAP® technology was developed for a ultra-low flow, high-pressure applications utilising a double diaphragm pump with an electric power pack.

Key Benefits of the New TC Series – Intelligent diaphragm pumps

  • Ultra low-pressure operation – reduced energy consumption.
  • Impossible to stall – revolutionary control technology completely prevents stalling.
  • Retrofittable – can be fitted to any existing Tapflo Air Operated Pump.
  • Available on all pumps from new – can be used on any pump in the Tapflo range.
  • Pulsation Reduction – minimising the need for a pulse dampener.
  • Improved Lifespan – LEAP® uses a seal-less air valve technology with significantly longer life expectancy over conventionally sealed valves.
  • Noise Reduction – lower air pressure = less noise of the pump.
  • Simplified Maintenance – main air valve can be changed in less than two minutes without the removal of the pump from the process line.
  • Simplified Control – integral solenoid valve control 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 – using the integral VFC output and an external predetermining counter the pump can be automatically stopped after the required volume has been dispensed.
  • Dry Running – monitoring the frequency of the output pulses from the pump can determine if the pump is running dry due to increased stroke rate.
  • Dead Heading – monitoring the frequency of the output pulses from the pump you can determine if the pump is stalled due to decreased stroke rate.

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 stall of the pump.

The TC Intelligent pump is able to start pumping at 0.1 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 air pumps 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%.

Case study

If considering the recent case of one of our customer, whose manufacturing process required the application of the pump to run all day, for 5 days a week, and if we consider this along with 48 weeks a year, the costs associated with the running of the pump were significant.

The estimated costs that the customer sustained using a 2” pump and a fluid flow of 150 L/min at 1 bar discharge and running the pump for 5 days a week were about € 2,133 each year. The customer recorded dramatic savings when he started using LEAP®  in the manufacturing process, reducing the costs to € 1,378 almost half of the initial energy costs per year.

Total Savings € 755 each year.
