Pump Systems supply special Egger TEO pump to WWTP for gas entrained sludge transfer

A difficult application at a Local Authority Wastewater Treatment Plant involving air entrained sludge required an advanced solution in order to overcome ongoing pumping problems. Pump Systems Ltd were able to offer the client a customised solution in the form of a new Egger TEO solids handling centrifugal pump. The special TEO impeller is designed to handle sludge and liquids with entrained gas contents of up to 15%.

With a solids concentration of around 6% as well being heavily aerated, the existing dry-mounted Flygt pumps were struggling to handle the difficult sludge, which had been described by the client as have a consistency similer to that of "melted icecream". By retrofitting a horizontal end suction Egger TEO pump and making some minor pipe work modifications, the DAF plant can now operate smoothly and reliably without pump issues due to entrained air.

Developed by Emile Egger & Co. in Switzerland, the TEO pump is a hybrid of Egger's successful TURO and EO models, providing the ability to pump highly charged liquids containing solids and entrained air. The TEO configuration is now finding application in water and wastewater industries around the world for pumping aerated sludge from DAF plants, activated sludge, etc to provide end users with reliable, efficient solids pumping performance at reduced life cycle costs.

Large Vaughan self priming chopper pump proves a success for waste slurry application at Australian paper mill

A large paper mill in Sydney, Australia required a reliable solids handling pump capable of transferring pulp waste slurry with high concentrations of suspended solids such as cardboard, strapping, etc. The solution offered by Pump Systems Ltd was a Vaughan SP8N self priming chopper pump. The latest in large, high efficiency self priming chopper pumps by Vaughan Co., USA are suitable for flow rates up to 1360 m3/hr and come with Vaughan's non-clog guarantee.

Complimenting the very successful smaller SP4 and SP6 models, the heavy duty SP8N (250 mm discharge) and SP10R (300 mm discharge) self priming chopper pumps use the same proven and patented design of a hardened impeller, cutter bar, upper cutter and cutter nut, allowing the pump to chop and pump solids laden waste material without clogging. Direct coupled to a 55 kW, 6-pole speed electric motor, the above pump has been running successfully now for some time and as a result, Vaughan self priming chopper pumps are being considered for similar applications in other areas of the plant.

Hastings, New Zealand

Difficult casings application requires heavy duty Vaughan chopper pump to handle stringy solids

A Vaughan vertical wet well chopper pump was recently supplied to a large processing company in New Zealand for pumping wastewater containing sheep casings, mucosa, slime, threads and intestines. Material of this nature is notoriously difficult to pump, as most pumps will not cope due to clogging and binding of impellers and shafts.  Pump Systems Ltd were able to offer the perfect solution with the patented chopping action of a Vaughan chopper pump.

The unique configuration of a Vaughan chopper pump means that the sharpened impeller blades meet with the arms on the cutter bar to effectively chop material as it enters the suction. In this case, to prevent stringy material from wrapping behind the impeller, which is particularly important when pumping casings, the upper cutter was finely positioned with minimum clearances to shred and remove any stray solids that enter the mechanical seal area.
