Task
Pump out abrasive slurries as well as wastewater, dirty water, and process water from wastewater tanks, storage tanks, and holding tanks. The fluids contain solids such as sand and must be conveyed reliably and with minimal wear.
Requirements
- Conveying abrasive media containing particles
- Reliable operation without downtime
- Low wear due to the conveying principle
Solution Details
The RFM 25 and RFM 40 air-operated diaphragm pumps with flap valves handle abrasive slurries and wastewater. The design, which has no rotating parts, reduces friction and wear. Flow rate and performance are controlled via the air supply.
Result
Reliable sludge pumping, even with a high solids content
Reduced wear due to the absence of rotating parts
High operational reliability thanks to automatic restart
Flow capacity up to 8 bar with a compact design
Quiet operation thanks to built-in silencers
