10 Frequently Asked Questions about Diaphragm Pumps?
Click here to get more.
1. What if the chemical to pump/diaphragm MOC (material of
construction) compatibility has &#;B&#; rating?
We do not recommend anything other than &#;A&#; rated combinations. Further, warranty of Antlia pumps
will be lapsed for the chemical to material rating &#;B&#;.
2. Can acids be pumped using Polypropylene (Plastic) pumps?
Acids can be pumped using PP diaphragm pumps after consulting a chemical guide for concentration
& temperature limits.
3. What is an FLR (Filter-Lubricator-Regulator) unit? What
purpose/use does it serve?
Air leaving a compressor is hot, dry or wet - which can damage & shorten the life of
downstream equipment such as Pumps, valves, etc. Before air can be used it needs to be filtered,
lubricated & regulated. An air ine filter cleans the compressed air.
4. Can AODD pump be operated at a pressure higher than recommended
max. pressure?
No. The pump may start leaking, diaphragms may bulge/wear & inner plates may bend.
5. How do I regulate the flow of Diaphragm Pump?
You can regulate the flow using the regulator on FLR unit or using a flow control valve to
increase or decrease the volume of air going to the pump.
6. Can an air operated diaphragm pump be submerged?
Absolutely, If the chemical is compatible with the pump MOC (material of construction) / housing
& the air exhaust pipe should be above the level of fluid.
7. The pump was working properly, but it has slowed down & not
getting the required capacity. What should be done?
Check fluid suction & discharge lines for any obstruction & also check valve sheets for
any dust or remains.
8. What is the life of diaphragms?
Diaphragms life depends on many variables. Inspection of diaphragms every 4-6 months is
recommended for continuous duty operations. The major factors leading to diaphragm failures are
pressure, temperature & moisture.
9. What is the max. viscosity an AODD pump can pump?

10. What is Antlia Pump&#;s Warranty?
We offer 1-year warranty against manufacturing defect from the date of purchase. These do not
include diaphragms as they are consumable part of the pump

Air Operated Diaphragm pumps, or AOD pumps, are a type of positive displacement pump powered by compressed air. A positive displacement pump provides a constant flow at fixed air supply pressure, regardless of changes in pressure. AOD Pumps are better suited for batch application processes, meaning the pump is only running for a certain time rather than continuously. The AOD Pump best serves its operators as a mobile low-cost fluid transfer pump that is versatile when it comes to the type of fluid you wish to run.
An Easy to Install, Cost Effective and Transportable Pump Option
An AOD pump can be easier to install over other types of positive displacement pumps. When installing your AOD pump all you need is a simple airline connection to power it; there is no need for electricity. Since the power comes from air rather than electricity, AOD pumps are fairly cost effective to operate.
Alongside the low cost of the AOD pumps, the mobility of the pump can also benefit its operators. AOD pumps can be moved from application to application rather than needing multiple pumps at multiple stations. They can function with very thin or highly viscous fluids. This means if the pump is properly flushed there usually isn&#;t an issue with switching fluids you are handling in the pump on any given day. *
Versatile Across Different Applications
AOD pumps are useful for a variety of commercial and industrial needs. They can pump a wide range of fluids such as fuels, glues, paints, resins, and ink. The AOD pump can also be used in the transfer of food-based or cosmetic liquids. In system applications, AOD pumps have many features useful for a variety of fluid transfer needs. AOD pumps can self-prime when the liquid level is below the pump and fully submerged if the air motor&#;s muffler is kept above the liquid level. You can also use the pump as a simple fluid transfer pump, as a tank, tote or drum unloading pump; even in dosing applications when small metering volumes are required. AOD pumps can be a remarkably effective tool to keep around the shop.
A Variety of Material Options Available
The fluid moving through the pump and the pump&#;s environment impact its life; this results in AOD pumps coming in varied materials. AOD pumps are available in metallic and non-metallic configurations with options for the external body material ranging from aluminum and polypropylene to Hastelloy and Kynar. A wide variety of material options ensure that an AOD pump can be constructed to meet your specific application need.
From their diverse fluid range to their ability to move where you need them, AOD Pumps can be a great multifunctional pump to have on hand at your plant.
*Check approved fluid types with manufacture of pump.
