as well as all kinds of pulps not liable to plait, sewage
water, chemical effluents.
- Municipal and industrial waste-water treatment
- Drainage
- Pulp and paper
- Food processing
- Sugar and alcohol
- Mining and manufacturing
- Civil construction
2. Design
Horizontal, single-stage, simple horizontal suction and
vertical upwards discharge. The “back-pull-out” design
allows maintenance and repair services through the back
side, without dismantling piping and alignment.
The available hydraulics and impeller types allow proper
selection for the handled liquid and required application.
