| | | ABS closed impellers | | |
| | | |
| | | The ABS closed impellers are designed for largerapplicationswhere high efficiency is paramount. The range includes single and multi channel closed impellers designed to give the optimum performance, without compromising effective rag and solids handling.The impellerdesign also includesa unique backshroud protecting the mechanical seal from spinning fibres, rag build up or excessive wear from grit. The impellers are available in the ABS submersible wastewater pumpAFPrangeandaresuitableforMunicipal Wastewater applications both in Wastewater Collection and Treatment. | | |

| | | ABS Vortex impellers | | |
| | | |
| | | The ABS vortex impeller has been designed to maximise the size of solids handled, allowing all items found in wastewaterto be passed without blocking the pump. The Vortex impeller is the natural choice when risk of blockage is high and lower efficiency can be accepted, for example storm water applications with low running hours. Othersuitable applications are pumping liquids containing air, gas, coarse particles or items which can become trapped. | | |

| | | TheABS Piranha cutting system | | |
| | | |
| | | The ABS Piranha cutting system offers a unique concept in grinder pump design. Our garden cutter design features a lobed rotor cutter attached to a centrifugal impeller togetherwith a stationary cutting element designed in a wave form. This causes an opening to be formed between the rotor and stationary cutter, which results in thehuge number of 15,000 cuts perminute.The solids are sheared into particles as small as 1 mm, which allows them to be pumped through small bore pipes. | | |

| | | ABS axial flow propellers | | |
| | | |
| | | The ABS submersible propeller pumpsVUPare ideal forapplications where large volumes of water have to be pumped upto heads of12m. They can be installed vertically in a space saving manner in a concrete riser or in a steel pressure pipe using a well proven coupling ring. Propellers with adjustable blades and special propellers for return activated sludge are available. They are ideal for storm water pumping stations, for polder dewatering, for storm water protection, for irrigation and dewatering. | | |

| | | ABS mixed How impellers | | |
| | | |
| | | The ABS submersible mixed flow column pump AFL for direct installation in a discharge pipe saves space and installation costs. They can be used everywhere where large volumes of stormwater or wastewater containing solid effluent must be pumped. TheAFLpumps can beapplied for sewage pumping in combination with screens suppliers, drainage pumps in pumping stations for dewatering reclaimed land in low lying coastal areas, storm water pumps for storm protection and transfer pumps to control the water level in lakes and lagoons. | | |

| | | Optimized hydraulic design using CFD technology | | |
| | | |
| | | ABS offers a complete range of impellers optimized using CFD technology allowing us to match your exact needs and giving you the best in efficiency and reliability. The strategy adopted is the combination of the Design of Experiments method (DOE) with NumericalSimulation (CFD). DOE is a numerical regression method allowing efficient analysis of multiple design parameters. In this case, factors critical to blockage performance are selected. CFD full transient numerical simulations are carried out in CFX-5 where we are also able to simulate unsteadiness in the Row of the single blade impeller, thus inducing inaccuracy in the less computationally expensive steady state analysis. The end result is a range of impellers optimized to handle different applications. | | |
