About Us

Roots Equipments & Pumps was established in 2016 with an aim to provide pumping solutions.
The company manufactures AODD Pumps and other pumping equipment — metallic & non-metallic.

• Pumps are self-priming

• Handle viscous & abrasive products

• Run dry without damage

• Built as per latest market trends

• Delivered within scheduled time

Benefits of AODD Pumps

• Runs dry without any damage

• Efficiently pumps solid-laden fluids

• Self-priming

• Ability to deadhead safely without damage

• Does not shear products while pumping

• Operates on compressed air (no electricity required)

• Lower purchase price compared to other pumps

• Performs well even when completely submerged

• Sealless design (no packing required)

• Variable flow and head pressures

Applications

• Paint

• Pulp & Paper

• Chemical

• Construction

• Marine

• Food & Beverage

• Oil & Gas

• Wastewater Treatment

• Mining

How the Pump Works

• The air valve directs pressurized air to the diaphragm.

• Compressed air moves the diaphragm, creating suction in one chamber and discharge in the other.

• Diaphragms alternate strokes (left & right), enabling continuous fluid transfer.

• Self-priming; may take several cycles to fully prime depending on conditions.

Installation Versatility

• Positive Suction – Suction side under fluid level (bottom tank draw).

• Negative Suction – Suction side above fluid level (drums, wells, etc.).

• Submerged – Pump placed inside tank; all wetted materials must be chemically resistant.

How to Select the Right Pump

Key Data to Gather:

• Viscosity

• pH value

• Specific gravity

• Size of suspended solids (if any)

• Required discharge rate

• Discharge head required

• Suction head (if any)

• Pipe diameter & no. of bends

• Chemical/physical properties of fluid

Diaphragm Material Options:

• Neoprene – General purpose, water/slurries; Temp: -18°C to +93°C

• PTFE – Aggressive fluids, acids, solvents; Temp: +4°C to +104°C

• Santoprene – Abrasion resistance, mild acids/alkalis; Temp: -40°C to +107°C

• Hytrel – General purpose, abrasion resistant; Temp: -29°C to +104°C

Pump Body Material Options:

• Polypropylene – Economical, good for pH 5.5–8.5

• Aluminium – General chemical compatibility, lightweight

• Stainless Steel (316L) – Strong acids/alkalis, rugged & durable
