Tapflo named its new pump series “TC Intelligent pumps”. The main step forward is the LEAP technology – ‘Low Energy Air Pump’. This is a patented technology used in AODD pumps to reduce the minimum operating air pressure by reducing internal losses and friction.

“LEAP uses an indirect system to detect the position of the diaphragm shaft controlling the diaphragm movement automatically”, explains Colin Wreyford Technical Director at Tapflo.

Technical paper by Erik Solfelt:

Thanks to its simple yet innovative design, the AODD pump has proven to be able to consistently meet the demands of chemical processors while building a reputation as a go-to pumping technology where basic fluid-transfer capabilities are required. The AODD pump, which possesses a stable of notable operational characteristics, has become a first-choice technology for chemical manufacturers who are searching for a pump that meshes cost-conscious air consumption with reliable and safe production rates.

12″, 10″ and 7″ H Series versions

Flotronic Pumps’ original 10” ‘H’ Series pump was designed to meet the exacting hygiene standards of 3-A Sanitary Standards, Inc (3-A SSI) and to be used in processes where hygiene is a priority. Since the launch of the 10” pump in 2015, the range has been expanded to encompass 7” and 12” versions, both of which are 3-A SSI accredited. Pipework connection sizes are now available from 1” – 3” allowing greater flexibility.

The new C-Series pumps have been specifically developed by Almatec to be a cost-effective alternative. The housing parts are tightened to each other via housing bolts. All of the C-Series’ bolts are tightened together against a diaphragm-sized ring on each side of the pump.

This design distributes the forces of the housing bolts onto the housing parts evenly, providing a consistent flow of forces that increases bolt torque and improves pump safety.

Flotronic’s ‘E’ Series pumps are air operated double diaphragm pumps (AODD). These pumps have proved themselves unmatched when tested to exacting performance standards by EHEDG (the European Hygienic Engineering & Design Group). The ‘E’ Series offers peace of mind for the food, beverage, dairy and pharmaceutical industries – and any environment or process where avoidance of product contamination is paramount.

The 10” version with 2” connections offers a pump solution ideal for customers with low to mid-range flow rate applications while customers seeking flow rates as high as 500 litres per minute will find the 12” pump with 1½” – 3” ideal.
