Centrifugal pumps for dense fluids and/or fluids with suspended solids.
RTK / RAO line
Discover the Multisteel Single-Stage Horizontal Pump : the solution that redefines versatility and efficiency for the most diverse pumping challenges. Its intelligent engineering allows the use of interchangeable impellers from the RTK and RAO lines in the same housing , adapting perfectly to everything from dirty and dense fluids without long fibers (RTK line) to liquids with suspended solids, abrasives, and a high fiber content (RAO line).
CONSTRUCTIVE FORM
RTK and RAO series impellers in the same casing.
Possible configurations:
- Horizontal bearing
- Vertical Dry Well and Wet Well in cantilever version
Additional resources:
- Rear vanes for axial thrust compensation
- Reducing the accumulation of solids on the back of the rotor
ROTOR DESIGN
- RTK line: tubular rotors, developed for pumping dirty and dense fluids without the formation of long fibers.
Examples: paper pulp up to 4%, honey, molasses, raw sewage, sludge, among others. - RAO line: open rotors, suitable for fluids containing suspended solids, particulates, abrasive fluids, fibers, and others.
Examples: raw sewage, bagasse juice, paper pulp up to 7%, among others.
BACK PULL OUT SYSTEM
Back Pull Out system allows for pump disassembly without the need to remove the casing from the piping, facilitating maintenance and component replacement.
VERSATILITY OF APPLICATION
The pumps are suitable for:
- Mixtures of water and sand
- Sewage (pre-screened and/or raw)
- Wastewater and drainage
- Viscous or dense liquids (mud, muddy liquids, broth with bagasse, etc.)
- Industrial fluids with suspended solids
Sectors served:
- Iron and steel industry
- Petrochemical
- Sugar and Alcohol Producer
