SDS – Solids Diaphragm Solution
The new Generation of Solids Handling Pumps
The Solids Diaphragm Solution (SDS) sets new standards in efficiency, ease of maintenance and reliability. With this new ABEL solution, we are setting new standards in the conveyance of thick slurries: our specially improved piston diaphragm pump significantly outperforms conventional technologies. The combination of optimized technology and smart control/analysis methods ensures maximum efficiency, maximum operational reliability, and future-oriented process control.
This pump system, developed for pump applications with high solids content and high viscosity, offers you a number of advantages over conventional solids handling pumps – and at significantly lower operating costs.
Up to 80 % lower operating costs compared to conventional solids handling pumps due to:
- Up to 50% shorter maintenance time
- Maximized maintenance intervals for high system availability
- Reduced spare parts costs thanks to low-wear components
- Higher energy efficiency
- High process reliability thanks to reliable technology and AI-supported pump monitoring
Technical Specifications
- Max. Flow: 22 m³/h (95 GPM)
- Max. Pressure: 6.4 MPa (925 psi)
- Solids Content: up to 30%
- ATEX design available
Housing
- Nodular cast iron
- Stainless steel
Applications
- Transport of sewage sludge from centrifuges, belt presses, screw presses
- Incinerator feed (e.g. mono-combustion)
The system’s maximum performance is achieved through the combination of AI and intelligent pump monitoring: the Smart Pump Assistant. This continuously monitors the health and efficiency of the pump, enabling predictive maintenance.
Why SDS is unique
- Over 40 years of experience in solids handling: From the classic SH pump to the SDS pump – continuous development for an optimal design.
- Valves at the highest level of development: specially designed for demanding applications, for maximum service life and easy maintenance.
- Deep understanding of the medium of sewage sludge: decades of practical experience with dewatered sewage sludge and conventional solids handling pumps form the basis for our solutions.
- Perfectly matched materials: The materials are specifically selected for the properties of the medium – for maximum durability and minimal downtime.
- Proven concepts taken further: Experience gained from SH pump design has been successfully transferred to the piston diaphragm pump and optimized for SDS technology.
For Sludge with a high Solids Content:
Innovative Pump Technology – Efficiency meets Durability
Our technical concept specifically combines the strengths of two proven pump technologies to create a customized overall solution. The progressive cavity pump takes over the feeding in the low-pressure range and ensures gentle and efficient filling of the pump chambers of the piston diaphragm pump. The low pressure reduces wear on the progressive cavity pump to a minimum – for maximum service life and low maintenance costs.
The actual pressure increase up to the desired operating point is then carried out by the special design of the piston diaphragm pump. This works with extremely low wear and impresses with its constant performance – regardless of the pressure level.
The result: a highly efficient, durable and easy-to-maintain pump solution that is perfectly matched to the requirements.
