Airwell pumping system overview  

The Airwell pump

Our unique air operated pumping systems are renowned for their reliability, adaptability and durability because of the following unique features:

  • Ability to handle high grit laden.
  • Ability to pump corrosive fluids.
  • Ability to adjust from very low to higher flow capabilities (0 - 100,000 litres per day).
  • A simple float valve on a tank can automate the Airwell system. When the tank is full the system will shut down until water level drops and the system will automatically restart. This "on demand" feature is built into every Airwell pumping system.
  • Ability to adjust to varying bore yields and self-regulate without damage to pump or bore. It actually can turn a non - producing bore into a reliable water supply.
  • Can operate long distances from electric power, sometimes up to 15 kms away.
  • Multiple pumps can be powered from the same compressor and airline.
  • High quality materials used (316S/S) and componentry manufactured to the highest standards.
  • Long service life with low maintenance characteristics due to few mechanical / moving parts.
  • Simple to install and operate.
  • Australian-made with all parts stocked locally.
  • Customised pumps / systems to suit a particular application.
  • Can be integrated with other pump systems.
  • Multiple pump systems can be controlled / monitored remotely.
  • Many systems include full SCADA remote monitoring and control.
  • Intrinsic safe options available for potentially dangerous / explosive environments.

The Airwell system setup

The main components of an Airwell system are:

  • The air compressor which can be single or three phase electric. It is usually located in a shed were a power supply already exists.
  • The airline which transfers the compressed air from the compressor to the pump location and can be 15km long or more if sufficiently sized.
  • The controller which is required to control the pump operation and can be either solar or mains powered. It is usually located on the surface close to the pump.
  • The cable kit which transfers the pump body "full" or "empty" signals to the controller.
  • The pump body which can vary according to the bore size and the required flow rate. It is located downhole.
  • The discharge water line can include valves and flow switches to control the required storage tank / dam water level.

 The Airwell system operation

  • The pump body is being allowed to passively fill at the natural production rate of the well.
  • Once the controller receives a "full" signal will pressurize the pump body with compressed air.
  • The pump's content is being discharged through the discharge line.
  • Once the controller receives an "empty" signal will discharge the pump body and let it start filling again.

Airwell pumps range  

Bottom filling pumps

  • Application: Bores (Water supply, Sampling, Leachate recovery)
  • Displacement: 0.8Lit - 50Lit
  • Body diameter: 45mm - 220mm

The most common Airwell pumps. They are designed to pump water, contaminated, corrosive fluids from bores and they last for many years.


Top filling pumps

  • Application: Bores (Fresh water harvesting above more saline water, Pollution recovery of floating contaminates)
  • Displacement: 1Lit - 12Lit
  • Body diameter: 45mm - 150mm

These pumps are designed to fill from the top. They can pump to the surface all liquid above the top of the pump. As the water level drops to the top of the pump, the pump stops cycling.


Sump pumps

  • Application: Sumps or inland waterways (Water supply, Leachate recovery)
  • Displacement: 13Lit - 25Lit
  • Min sump diameter: 550mm

These pumps are designed to be submerged in sumps and keep the water level as low as possible.


Transfer pumps

  • Application: Water lines (Transfer the water in long distance, Lift the water up a steep rise)
  • Displacement: 25 Lit

The purpose of this pump is to get connected in series with the water line at one or more stages. It can give the water a total dynamic head of up to 80m at each stage.


Floating pumps

  • Application: Waterways, Dams, Lakes (Water supply, Leachate recovery)
  • Displacement: 25Lit

This floating pump has been used for more than 20 years in multiple locations throughout Australia. The compact pump and controller design allows the system to be highly mobile in applications where a single pump may be moved for use in multiple locations.


Evaporating pump

  • Applications: Ponds (Leachate evaporation)
  • Displacement: 95Lit

This floating pump has been succesfully used to increase the evaporating rate of leachate ponds. The filling procedure is quick thanks to the 8 inlet screens. With the 4 sprinklers attached at the corner posts, water is sprayed all arround at a big domed shape. All the sprayed tiny drops increase massively the liquid face in contact with the atmosphere, accelerating evaporating procedure.


Oil and Gas pumps

  • Application: Gas wells (Deliquification)
  • Displacement: 65Lit
  • Body diameter: 142mm

Our top quality, minespec, high pressure pump designed to operate at 1500m depths. It can successfully replace the expensive to maintain progress cavity pumps, and make a low producing bore profitable for many years on. Safe and wear resistant construction are the main design aspects of this high pressure gas operated pump. Pumping flow rate can be remote controlled and adjusted to each bore's specific requirements. Coal fines and mud can be pumped without damaging the pump for a long period.

Airwell controllers range  

Solar controller

  • Application: Agricultural, Farming, Industrial
  • Capacity: 1 pump
  • Intrinsic safe: No

This controller is ideal for use where a water bore is located far away from an electrical supply.

Thanks to the integrated solar panel and battery combination it can control the Airwell pump operation and provide water supply 24/7.

The amount of pumped water can be found with the integrated counter.


Basic controller

  • Application:Agricultural, Farming, Industrial
  • Capacity: 1 pump
  • Intrinsic safe: Optional

This is a mains powered controller, so it has to be close to an electrical supply.

If powered by a 8 x 8 skid controller can be intrinsic safe as an option.

The amount of pumped water can be found with the integrated counter.


S/S enclosure controller

  • Application: Industrial
  • Capacity: 3 pumps x 3 bubblers max
  • Intrinsic safe: No

This is a mains powered controller, so it has to be close to an electrical supply.

It can control up to 3 pumps and 3 bubblers.

The amount of pumped water can be found with the integrated counter.

The water level in the bores can be found with the pressure gauges located inside the enclosure.


Portable controller

  • Application: Industrial (sampling)
  • Capacity: 1 pump
  • Intrinsic safe: No

This portble controller can be powered by mains (via transformer) or straight from the car battery (via cigarette lighter plug).

The amount of pumped water can be found with the integrated counter.

It also contains a dual timer which makes it suitable to operate a pump without using the probe signal.


Skid controller

  • Application: Industrial
  • Capacity: 8 pumps x 8 bubblers max
  • Intrinsic safe: Optional
  • Telemetry: Optional

This controller is ideal for use where multiple water bores are located far away from an electrical supply.

It can control up to:
- 16 Airwell pumps
- 16 Bubblers
- 16 Flow meters
- 16 Air line pressure sensors
- 16 Temperature sensors
- 16 Air compressors (ModBus through ethernet)

The above data can be monitored local on the PLC dispaly or remotely on your PC.
Pumped cycles, flow meter volumes and bubbler levels are being logged hourly.
Pumps and compressors operation can be controlled remotely (start / stop).

Thanks to the integrated solar panel and battery combination it can control the Airwell pumps operation and provide water supply 24/7.

Intrinsic safe and telemetry are available as an option.


Air compressors range  

Airwell is an official Pilot air compressor agent.

For small scale projects (agricultural, environmental) stand alone reciprocating compressors can be supplied.

For large scale projects (mining, landfills) screw compressors can be supplied inside shipping containers.

Solar pumping systems  

The solar pumping proposal from Airwell consists of a galvanized steel frame and a Franklin solar powered submersible pump.

There are many frame types available to suit any combination of solar panels, according to the customer's needs.

The Franklin submersible is 100% controlled by a VSD optimised for solar powered systems. In order to improve efficiency, no batteries exist to the system.

In some specific cases an Airwell pumping system can be mounted instead of the Franklin one.
