Diaphragm Pumps are one of the most popular pumps available on the market. Here at TS Pumps, we supply a range of Diaphragm Pumps from one of the leading manufacturers around the world, Tapflo. They are renowned for their innovative Pump technology and use of fewer parts than many others on the market.
A Diaphragm Pump is a Positive Displacement Pump that transfers fluid via diaphragms working together to push the liquid through the system within the pump.
The pumps we supply are driven by compressed air and are also referred to as Air-Operated Double Diaphragm Pumps or AODDs.
View the full range of Air Operated Diaphragm Pumps.
An Air Diaphragm Pump works by using the following operation:
Metal – Available in Aluminium, Cast Iron or Stainless Steel AISI 316, a Metal AOD Pump is perfect for handling fluids that are viscous, chemically aggressive or contain coarse solids.
HDPE & PTFE – Available in solid block polyethene and solid block PTFE. The pump housing is machined from solid block plastic to ensure the design is strong enough to withstand mechanical force. It also helps protect against aggressive chemicals without creating weak points for leakage.
Our Metal and HDPE & PTFE ranges are also available as ATEX rated upon request and you can view both pumps in the ranges linked above.
Sanitary – Our Sanitary range is designed specifically for industries that require the highest level of hygiene. These include food, beverage, cosmetic and pharmaceutical industries. ATEX, EHEDG, USP VI and FDA approved.
If you’re looking for more information on TS Pumps’ range of Sanitary Pumps, not just Air Pumps, check out our Sanitary Pump Guide.
AOD pumps usually do well with a Pulsation dampener fitted to the top of the pump to help minimise the vibrations caused by the air driven operation. This allows there to be a constant level of flow to suit your application pumping requirements. The Pulsation Dampeners TS Pumps supply can also be ATEX rated (upon request) for potentially harmful chemical applications.
Chemical Industry – Acids, shear sensitive liquids, alcohol, solvents.
Hygienic Applications – Food products, cleaning liquid for CIP, cosmetic products such as toothpaste and perfume.
Water Treatment – Transferring sludges, chemical reagents, dosing for pH control.
Surface Conditioning – Transferring chemicals from tanks and containers, handling waste products.
Mechanical Industry – Oils, lubricants, cooling liquids.
Pulp and Paper Industry – Titanium oxide, bleaching products, glue
Paint, Print and Varnish Industry – Ink, varnish, adhesives, solvents, blending & recirculation of ink, water- and solvent-based paints.
The vast range of accessories that we can supply with a Diaphragm Pump also widens the application range.
The inlet and outlet ports on your pump can be turned to fit whatever pipe installation is required. This makes them highly versatile and easier to connect to your existing pipework. Below we have listed the various installations available when using a Diaphragm Pump.
Flooded is the ideal installation solution to completely empty a container or where the fluid being transferred is particularly thick. This is because the piping system has a positive suction head.
The pumps can be submerged within the fluid being pumped and work to push the liquid out. The Diaphragm Pump will need an air exhaust from the container in order to expel air to the atmosphere and allow the pump to “breathe”.
An AOD can be installed above the fluid that you are transferring due to a suction lift of up to 8 meters from a wetted pipe (this is 5m if the suction pipe is empty). The suction capability will depend on the pump size that you purchase.
Our range of pumps is made from 70% less parts than other AODDs on the market. This makes them easier to disassemble and makes maintaining your pump straightforward!
4 easy tips for ensuring that your AOD pump runs smoothly:
If you’re having any issues with your pump, let us know what problem you’re having and we’ll use our expert pump knowledge to advise on the best course of action! Call us on 01928 333 400 or drop us an email at [email protected]
You should be regularly checking your pump as maintenance is a key priority and takes no time at all when purchasing one of the Diaphragm Pumps from our range. We also recommend a complete inspection of your Diaphragm Pump once a year (at a minimum).
It is well known that AOD Pumps are not the cheapest pump to run due to the cost of compressed air. Yet with running costs typically surpassing the original price of the pump itself, they’re still an enormously popular pump. In these instances, an enormous saviour is swapping your current Pump for LEAP technology. The Low Energy Air Pump can start at the lowest starting pressure known as a pump on the market. Meaning investing in LEAP could save your company up to 70% in energy costs! LEAP is a revolutionary technology and designed to provide low flow rates for high-pressure applications.
LEAP can be retrofitted to any Tapflo, Dellmeco or Almatec Diaphragm Pump, and is available in plastic, metal and sanitary.
Air Pumps can handle up to 15,000 cPs, although if the pump is operated using fluids at the maximum viscosity, the flow rate is around 20% of the nominal flow on the water. If the product being pumped is more than 2,000 cPs, we recommend installing your Air Pump in a Flooded installation (as mentioned above) to aid the pump with the flow rate.
