Technical Overview
Diaphragm pumps are a type of positive displacement pumps. A flexible diaphragm in the pump head is moved up and down via the condor and through the action of an eccentric on the motor shaft. On the down stroke, the medium is drawn into the pump chamber and expelled on the upstroke. Internal valves mounted within the pump head function as check valves and control the direction of flow.

Gas Diaphragm Pumps
Equally suitable for use as a vacuum pump, they are characterized by low sound level, high efficiency and gas tightness. Models are available with AC or DC drive. vacuum to 250mmHg abs, pressure to 3,0 bar and flow rate in the range from 0,8 to 9 litres per minute.

Most of AGI diaphragm pump product lines feature several motor options ranging from low cost DC up to AC solutions. The sealed air path is inherent to the design itself. Chemical resistance is addressed with different pump head and elastomer materials such as PPS (Ryton) or FKM (Viton). Other attributes include operational water vapour tolerance, working point controllability and a very good size to performance ratio.
Typical applications profiting from above mentioned features are handheld or portable gas detectors and analysers. Here, leak tightness and chemical resistance comes into play. Dental autoclaves or Negative Pressure Wound Therapy (NPWT) rely on pump controllability, a low sound level or pump lifetime and efficiency due to brushless DC configurations. Various laboratory applications or wherever efficient, compact vacuum pumps or compressors are required round off target applications.

APPLICATION FOR SAMPLING PUMP AC & DC

• Environmental Solutions
AGI offers pumps for gases, vacuum pumps and compressors for variety of environmental market applications. Our Diaphragm covers applications starting from gas detection and analysis, up to aquaculture, battery and pond aeration, sewage aeration, greywater treatment. Our oil-less units provide long-lasting high efficiency performance and comes in all sizes to power both stationary, portable and handheld devices.

• Gas Detection
Gas detectors detect the presence of gases in risk areas or confined spaces often as part of a safety system. These gases can be toxic or explosive. Hence, quick detection is imperative for alerting personnel working in hazardous areas and warning them to clear out if certain concentration levels are exceeded.

• Continuous Emissions Monitoring Systems
Continuous Emissions Monitoring Systems (CEMS) continuously monitor volatile hydrocarbons and other gases present in emissions escaping to the atmosphere through industrial smokestacks. Government regulations and standards determine acceptable concentration levels that shouldn't be exceeded.

• Pond/Sewage Aeration
The micro bubbles with oxygen inserted into the water accelerate the growth of bacteria that break down the waste. Aeration systems provide ponds and lakes with aeration, circulation, and de‐stratification to increase dissolved oxygen levels throughout the entire water column. Thanks to that they help to reduce organic sludge, venting toxic swamp gases, reducing nuisance pond weeds, encouraging the growth of beneficial algae, and preventing winter fish kill.

Water Processing/Treatment
Large amounts of air are passed through water and then ventilated to the atmosphere. The air causes the release of dissolved gases such as radon, carbon dioxide, methane, and hydrogen sulfide as well as volatile compounds like MTBE (Methyl tert-butyl ether) or industrial solvents as well as iron and manganese from the water.

• Condensate Removal
Gas coolers and various condensate collecting vessels require a pump that continuously discharges gathered condensate. Liquid pumps - peristaltic pumps in particular - are the perfect fit for condensate removal, thanks to their advantages. They can operate in dirty environments and transport fluids that contain particulates. On top of that, peristaltic pumps are self-priming and dry-running.

• Benefits of AGI Diaphragm Technology
Our state-of-the-art engineering and design guarantees sealed air path and reliability. We provide a selection of materials for the pump head and membrane based on a chemical resistance to the media being transferred. Our customers can choose the material for diaphragm and valves among EPDM, FKM (Viton), Silicone, PTFE (Teflon), depending on the model selected.

• AGI Diaphragm Characteristics
We provide both AC and DC motors with variants. AGI diaphragm pumps for gases, vacuum pumps provide a flow rate ranging from (800 ml/min) up to (10 l/min), with a vacuum to (150 mmHg),

• Your Trusted OEM Pumps Partner

How Diaphragm Pumps Work?

Diaphragm pumps work by reducing a volume from the pump chamber using a flexible membrane in the pump head. A crank moves the pump head through the eccentric motion on the motor shaft. These positive displacement pumps feature the leak-proof pump chamber, operational water vapour tolerance, and outstanding chemical compatibility. The design allows them to transfer various gases even with particles.
