What is an Air Operated Double Diaphragm (AODD) Pump?

An AODD pump (also called AOD pump, diaphragm pump, or pneumatic pump) is a positive displacement pump that uses compressed air to move fluids via two flexible diaphragms. It handles corrosive, abrasive, viscous, and shear-sensitive liquids and can run dry without damage. Antlia Engineering Works manufactures AODD pumps in Mumbai, India.

How does an AODD pump work?

Compressed air is supplied to one diaphragm, pushing it outward and creating pressure to discharge fluid. This simultaneously creates a vacuum on the other side, drawing fluid in. A valve system alternates the air supply between the two diaphragms, creating continuous pumping action without any electricity.

What are the advantages of using an AODD pump?

Key advantages of Antlia AODD pumps include: self-priming up to 5m suction lift, explosion-proof operation (no electricity needed), dry-run capability without damage, handles solids and viscous fluids, zero leakage seal-less design, variable flow rate, portable and lightweight, and easy maintenance with modular spare parts.

In which industries are AODD pumps used?

Antlia AODD pumps are widely used in chemical processing, pharmaceutical manufacturing, oil and gas, paint and coatings, printing and inks, food and beverage, wastewater treatment, automotive, mining and slurry handling, textiles, cosmetics, and agriculture industries.

What is the price of an AODD pump in India?

AODD pump prices vary based on size (1/2 inch to 3 inch), material of construction (PP, PVDF, SS316, Aluminium), and diaphragm material (Buna-N, Viton, PTFE). Contact Antlia Engineering Works at +91 9819395995 or antliaworks@gmail.com for a free same-day quote.

Frequently Asked Questions

Which AODD pump material is best for sulphuric acid?

PVDF and PTFE (Teflon) are rated A (Excellent). PP is suitable for dilute concentrations up to 30%. Aluminium and SS-316 should be avoided.

Which AODD pump material is best for hydrochloric acid (HCl)?

PTFE and PVDF are rated A at all concentrations. PP is suitable for dilute HCl. Neoprene, SS-316, and Aluminium are not recommended.

Can AODD pumps handle solvents like acetone and toluene?

For acetone, SS-316 and PTFE are rated A. For toluene, metallic pumps (AL or SS-316) with PTFE diaphragms are recommended. PP and Neoprene are not suitable.

Which pump material is best for food and pharmaceutical applications?

PTFE, PVDF, and Santoprene are FDA-approved recommended materials for food-grade and pharmaceutical fluid transfer.

What is the difference between PTFE and PVDF?

PTFE (Teflon) has the broadest chemical resistance. PVDF (Kynar) is mechanically stronger for higher pressure applications. Both FDA-approved.

What does Rating D mean?

Rating D (Not Recommended) means the material will be significantly damaged. Always select A or B rated materials. Contact Antlia if you need confirmation.
