A: We will reply within 2 hours of receiving your enquiry on working days.

A: We are a manufacturer with our own export team, handling both production and sales.

A: Yes, we can develop and manufacture products based on customer-provided drawings or samples.

A: Our pumps are exported to over 100 countries and regions worldwide, with key markets including Germany, the United States, Brazil, Japan and South Korea (spanning Europe, North & South Americas, East Asia, Southeast Asia and the Middle East).

A: AODD pump applications are broad because AODD pumps are capable of safely and effectively handling anything from water to solids-laden slurries—including volatile and dangerous liquids. Their flexibility allows one pump to tackle numerous applications without costly motor drives or critical sizing calculations. AODD pumps offer additional advantages that competing pumps can’t match. AODD pumps:  Run dry without damaging the pump or system; Require no electricity; Can be installed in suction lift applications, flooded suction applications and submerged applications; Meet required industry certifications; No mechanical seat, easy maintenance, low cost; Explosion-proof, zero leak, simple operation; Few components & long life design; Lubrication free air distribution system.

A: Acids can be transferred using PP diaphragm pumps after consulting a chemical resistant guide for concentration & temperature limits.

A: 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 airline filter cleans the compressed air.

A: No. The pump may start leaking, diaphragms may bulge/wear & inner plates may bend.

A: 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.

A: 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.

A: Check fluid suction & discharge lines for any obstruction & also check valve sheets for any dust or remains.

A: 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.

A: 20,000 cps is the max. viscosity which is recommended considering ideal conditions.

A: Though AODD pumps are known for their consistency and reliability, just like any piece of equipment, they need routine maintenance to ensure long-term durability.   Fortunately, wear components of an AODD pump are limited. Common wear components include:   Diaphragms Balls Seats Flaps

A: 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.

A: When installing a new AODD pump, or one that was repaired and placed on the shelf for later use, you should always check the tightness of the pump’s hardware.  Though this seems intuitive, many operators don’t know that pump hardware tends to loosen up due to material creep, vibration in transit and temperature changes.  Remember: It's important that the pump isn't under pressure when tightening hardware.
