1/2 Inch AODD Pump

A compact air-driven solution for controlled fluid movement

Designed for installations that call for a smaller process connection, this half-inch air-operated double diaphragm pump uses compressed air to drive the pumping cycle. It is listed with a maximum flow rate of 35 LPM and several body-material configurations for application-based selection.

Choose the construction to suit the fluid and operating environment, and confirm the required duty conditions before ordering.

Model overview

Where the Half-Inch Configuration Fits

A smaller connection format for fluid-transfer points where capacity, piping and material requirements align with the duty.

The 1/2 inch AODD pump is part of Ambica Machine Tools' air-operated diaphragm pump range. Rather than relying on an electric motor mounted to the pump, the unit is driven by compressed air. Its double-diaphragm mechanism moves fluid through the inlet and discharge ports as the air cycle operates.

This model is specified with 1/2 inch BSP (15 mm) process connections and a maximum flow figure of 35 litres per minute. These are reference limits; actual delivery can change with air supply, fluid properties, pipework and system resistance.

Construction choices listed for this model include Polypropylene, PVDF, Stainless Steel 316 and Aluminium. The appropriate option depends on the fluid being handled and the conditions in which the pump will operate. Confirm compatibility of all wetted parts, seals and diaphragms before selection.

For a suitable recommendation, share the fluid name, temperature, required flow, transfer distance and available compressed-air supply with the Ambica Machine Tools team.

Application guidance

Consider the Process Before Choosing the Pump

The right application depends on fluid compatibility, required output and installation conditions—not on nominal size alone.

↗

Small-Line Fluid Transfer

Consider this connection size where a 1/2 inch BSP inlet and discharge arrangement matches the process piping.

⚙

Air-Driven Pumping Setups

Useful to assess where compressed air is the selected drive. Confirm that the available air supply meets operating requirements.

◇

Material-Specific Duties

Review plastic and metal body choices against the chemical, temperature and process conditions of the fluid.

⇄

Process and Utility Transfer

Evaluate for transfer tasks where listed flow, port size and wetted materials are appropriate for the duty.

◎

Intermittent Transfer Points

Discuss operating frequency, start-stop needs and air availability when assessing the pump for a particular line.

✓

Equipment Integration

Check connection standards, pipework, suction conditions and discharge resistance as part of system design.

Important: These are application categories to assess, not a guarantee of chemical suitability. Confirm the exact fluid, concentration, temperature, seals and diaphragm material before use.
Design points

Features to Review on This Model

These points focus on the listed configuration and practical checks during selection.

01 / DRIVE

Compressed-Air Actuation

The pumping cycle is powered by air rather than a motor mounted to the pump.

02 / SIZE

Half-Inch Connections

Specified with 1/2 inch BSP process connections, identified as 15 mm in the reference.

03 / OUTPUT

35 LPM Listed Flow

The supplied reference gives 35 litres per minute as the maximum flow rate.

04 / M.O.C.

Multiple Body Options

Listed choices include PP, PVDF, Stainless Steel 316 and Aluminium.

05 / AIR

Defined Air Inlet

The air inlet is listed as 1/4 inch BSP; confirm supply details for your duty.

06 / SUCTION

Lift Values Provided

Reference data lists 1.45 m dry and 2.83 m wet suction lift.

07 / PARTICLES

Particle-Size Limit

The maximum particle size in the supplied specification is 2 mm.

08 / SELECTION

Duty-Based Configuration

Material and operating conditions should be checked together before ordering.

Material selection

Available Construction Choices

Ask the supplier to confirm complete wetted-part construction for the fluid you need to transfer.

Polypropylene (PP)

A listed thermoplastic body option. Check chemical compatibility and temperature limits for the intended liquid.

PVDF

A listed fluoropolymer option. Confirm suitability against the exact chemical, concentration and process temperature.

Stainless Steel 316

A listed metal construction option. Verify corrosion resistance and compatibility for the specific process fluid.

Aluminium

A listed metal body option. Confirm that the fluid and environment are appropriate for aluminium construction.

Body material alone does not establish complete chemical compatibility. Diaphragms, seals, valve components and other wetted parts must also suit the fluid.

Frequently asked questions

Questions About the 1/2 Inch Model

Quick answers to common selection and specification questions.

What is the listed maximum flow for this half-inch pump?

The supplied reference lists a maximum flow rate of 35 LPM. Actual flow depends on operating conditions, fluid characteristics, air supply and system resistance.

Which construction materials are available?

The listed material options are Polypropylene (PP), PVDF, Stainless Steel 316 (SS-316) and Aluminium. Confirm fluid compatibility before selecting a configuration.

What are the process connection and air inlet sizes?

The reference lists 1/2 inch BSP (15 mm) process connections and a 1/4 inch BSP air inlet. The port dimensions should be checked against the current drawing or datasheet.

What suction-lift values are shown?

The supplied data lists 1.45 m dry suction lift and 2.83 m wet suction lift. It also lists Teflon dry and wet values separately; ask the supplier to confirm the applicable configuration and test conditions.

Can the pump transfer any chemical if the body is PVDF or SS-316?

No material should be assumed suitable for every chemical. Confirm compatibility for the exact liquid, concentration, temperature and all wetted components, including diaphragms and seals.

What information should I share for a recommendation?

Share the fluid name and concentration, temperature, required flow, suction and discharge conditions, available air supply, connection standard and any solids present in the liquid.
