Air-Operated Diaphragm Pump Range
Our wide range of diaphragm pump systems is available for a variety of applications and executions:
- Standard Diaphragm Pumps available in Metal, HDPE, PTFE or Sanitary
- Low Energy options to reduce your business’s energy consumption and reduce costs on compressed air
- Complete Tank solutions, ideal for transferring, dosing and storing fluids
- Mobile Decanting Units including AOD and pneumatic control and monitoring system
- ATEX certified Diaphragm Pumps for potentially hazardous environments
Up to 70% fewer parts than our competitors
With many Air-Operated Diaphragm pumps on the market, there is an unnecessary amount of bolts and extra parts present in the pump system which can lead to more weak points and opening for leakages to occur. Tapflo prides itself on offering a simple and easy to operate diaphragm pump with up to 70% less parts compared to competitors on the market.
The side housings on the Tapflo diaphragm design features side housings that can be machined from solid block HDPE, PTFE, Cast Iron, Aluminum or Stainless Steel. This design ensures that the frame is stronger to withstand aggressive fluids and increases the life of our pumps.
In every Tapflo Diaphragm Pump, we use no-nut, clean face diaphragms. This ensures that the diaphragms are primed for heavy-duty operation and increases their life span. Rather than using a nut to hold the components of a diaphragm together, they are chemically bonded.
Of course, all diaphragms eventually rupture from general wear but by swapping your diaphragms, you can increase the life of the diaphragms and protect your pump from damage caused by leaks.
Tapflo uses high-grade, reliable materials to manufacture our pumps:
Plastic range: HDPE (Polyethylene) is 6-7 times more wear-resistant than Polypropylene and can withstand temperatures up to 70°C. We also manufacture our pumps from PTFE (polytetrafluorethylene) which has a superior chemical resistance due to it being a thermoplastic polymer, therefore, it can withstand temperatures up to 100°C.
Metal range: We also produce pumps in Stainless Steel AISI 316L which is a high-quality grade material used across our range. Also available in Aluminium and Cast Iron. Similarly, Tapflo’s Sanitary Diaphragm Pumps are manufactured from Stainless Steel AISI 316L and supplied, as standard, with an extra-fine surface finish to Ra 0.8 or Ra 0.5 upon request, to meet the strictest of hygiene standards.
A wide selection of our Air-Operated Diaphragm Pumps is also available as ATEX for hazardous environments. The pumps are manufactured with carbon filled, conductive plastic and our Metal AODs feature carbon centre sections like in the image here. This material safeguards the pump from electrostatic building inside the pump.
Tapflo’s Air-Operated Diaphragm Pumps are easily installed on-site which helps businesses to keep service costs down to a minimum and allows quick and easy maintenance. On Tapflo’s HDPE/PTFE series, the connection at the top of the pump can be rotated 180°, meaning our Diaphragm Pumps also allow flexible installation, as it turns easily to fit the piping system that you have in place.
There is also a wide range of installation possibilities for Diaphragm Pumps. Tapflo’s AOD Pumps can be submerged in the fluid, they can be installed above the medium as they can create a high vacuum suction or they can be installed with flooded suction. Our team can meet a range of installation and application requirements.
Low Energy Options
Due to Air-Operated Diaphragm Pumps using compressed air, they can be expensive to run. An alternative to this would be Tapflo’s LEAP technology! LEAP stands for Low Energy Air Pump and has been designed to allow the pump to begin operating at a much lower pressure than standard AODs, therefore reducing the cost of compressed air for your business.
The technology is available in all Tapflo Diaphragm Pumps and is sold globally through the Tapflo network. Head to our Low Energy Diaphragm Pump page on our website to find out more!
If you’re worried about the costs associated with Air Pumps, then Tapflo has the solution in our article, where you can find out about the benefits of switching to LEAP.
Air Operated Diaphragm Pump Case Study Solution
Tapflo has provided previous customers with bespoke Diaphragm Pump solutions to suit their applications and industries. One, in particular, featured four Diaphragm Pumps, all T100s in HDPE, with stroke sensors. Take a look at our case study about how we provided an end-user with a suitable solution to pumping in a highly corrosive atmosphere.
