ALLWEILER AE-RG Hopper Pump Series delivers reliable performance for challenging solids and sludge handling

CIRCOR International has highlighted its ALLWEILER AE-RG Hopper Pump Series, engineered for superior performance in demanding environments.
This Hopper Pump Series is engineered for efficient and reliable transfer of highly viscous, abrasive, or solids-laden materials, making it ideal for demanding environments such as wastewater treatment, especially dry sludge handling, biogas and various other processing applications.
The AE-RG Hopper Pump Series features an optimized hopper design that provides smooth and efficient transfer of materials, including substances with up to 45% dry solids content.
This robust approach ensures a continuous pumping of non-free-flowing, dewatered, or fibrous products, ranging from high viscous and sticky starch to highly dewatered and solid-laden municipal sludge.
The series leverages progressing cavity pump technology to seamlessly handle the most challenging media, promoting lasting, dependable operation in challenging settings. Each pump includes two intermeshing augers.
The two augers are optimised for every application and can be designed either as mixing or conveying screws; even a mix of both types is possible.
This prevents bridge building and clogging at the inlet hopper, guaranteeing uninterrupted performance even with difficult-to-handle materials, without the need of separately-driven and energy-consuming bridge-breakers. The option of mixing screw design also allows customers to add conditioning agents or other additives through a bypass line into the inlet hopper and get it blended into the main pumping media.
With capacities up to 560 liters per minute and pressure ratings up to 24 bar, the ALLWEILER Hopper Pump Series delivers consistent, pulsation-free flow even under high demand and at fluid temperatures up to 135c.
This combination of features enables process operators to achieve trouble-free pumping of problematic materials and supports continuous operation, improved process control, and productivity across a wide range of industrial and municipal environments.
