Installed in waste water treatment and sewage aeration applications, the Charles Austen Pumps range of linear pumps runs to the highest standards in performance and reliability, whether at the first stage of treatment or removing the waste water after treatment.

Charles Austen Pumps also stocks a wide range of water and air pumps, ideal for use in both aquatic and hydroponic applications. The range is suitable for those with a single tank or home growing system up to aeration for large koi ponds and fish breeders. Continuous investment is put in to ensuring an up to date product range; this, combined with in house knowledge, means Charles Austen is always on hand to ensure you own and use the most appropriate products.

Finally, the BlueDiamond range of condensate removal pumps which has been designed for use in air conditioning and refrigeration applications has been designed, developed and manufactured within the Charles Austen factory. With the BlueDiamond patented pumping principal, all pumps and accessories are designed with the installer and end user in mind.

Our Technologies

Rotary Diaphragm

The patented rotary diaphragm technology has a revolutionary pumping principle. The flow of liquid is initiated by an eccentrically mounted bearing on a drive shaft which revolves within a flexible diaphragm. As the shaft rotates, the bearing flexes the diaphragm, squeezing liquid through the pump.

GyRok™ Technology

Rotary diaphragm pumps use unique Charles Austen patented technology. The flow of liquid is initiated by an eccentrically mounted bearing on a drive shaft revolved within a flexible diaphragm. As the shaft rotates, the bearing flexes the diaphragm, squeezing liquid through the pump. These pumps have outstanding self-priming characteristics and are of a valve-less, seal-less design.

Diaphragm

The major advantage of the diaphragm pump is that the pumping chamber is totally sealed and, therefore, does not require a sliding seal between moving parts. Vacuum and pressure are produced by the flexing of the diaphragm back and forth in the chamber. The reciprocating action is created by an eccentric driven connecting rod under the diaphragm. The pumps can handle corrosive gases and vapours when the correct materials are specified and are completely oil-free which makes them ideal for use in applications where contamination cannot be tolerated.

Linear Diaphragm

The simple yet efficient pumping principle uses a magnetically operated diaphragm. This action flexes a diaphragm at one, or both ends of the connecting rod within a totally sealed pumping chamber. This eliminates sliding parts keeping wear, tear and power consumption to a minimum.

Rocking Piston

Rocking piston pumps combine the higher performance of a piston pump with the simplicity of a diaphragm pump in a small economic unit. The piston is fixed rigidly to the top of the connecting rod. An eccentric drive causes the piston to reciprocate and a flexible seal maintains contact with the cylinder walls, compensating for the rocking piston. The pumps are capable of operating continuously with a minimum of maintenance and offer high performance, particularly pressure, within a compact package.

Centrifugal

Centrifugal pumps incorporate a rotary impeller which draws the liquid into the inlet. The centrifugal action forces the fluid to the extremities of the chamber and through the outlet at pressure. Due to their valveless design, the output from these pumps is completely smooth and gives good flow performance from a compact unit.

As the leading manufacturer of vacuum pumps and compressors for use with air, gas and liquids, not only does Charles Austen offer off the shelf units, but also adaptations of standard OEM products. The Charles Austen Pumps research and development team is based in-house and is able to design new pumps from concept to production. Charles Austen Pumps is passionate about meeting customers' needs and always welcomes the opportunity to discuss new applications. Call 01932 355277 to talk through your unique pump.
