Vertical Axis Pumps
Vertical Shaft Pumps are essential devices for sludge treatment in various industrial applications, such as the marble and granite industry, mining operations, aggregate treatment and the ceramics sector. These pumps are designed with robust bearings that allow the lower part of the shaft to cantilever, eliminating the need for liquid-immersed supports and associated seals.
The bodies of the vertical axis pumps can be made of super hard cast iron to resist wear, or coated with abrasion-resistant rubber for greater resistance to abrasion and corrosion. They are available with two types of drive: belts and pulleys for greater point-of-operation optimisation, or direct coupling via mechanical coupling for easier operation and maintenance.
Thanks to their robust design and durable materials, these pumps offer a long service life even in harsh conditions. Drive systems optimise pump performance according to specific needs. The cantilevered configuration and absence of submerged supports reduce maintenance and downtime.

Technical features and advantages of Vertical Axis Pumps
Vertical slurry pumps are a type of centrifugal pump designed for pumping thick, viscous liquids. They feature a vertical configuration that allows for compact and simplified installation, especially in confined spaces.
Technical features:
- Vertical design: as mentioned, the pump is positioned vertically, with the electric motor above the pump itself. This design reduces the footprint and simplifies access for maintenance.
- Different types of impellers: vertical axis pumps for sludge can be equipped with different types of impellers, each with its own flow and head characteristics. Impellers with a large diameter allow a high head to be achieved, while those with a smaller diameter favour a higher flow rate with the same power input.
- Construction materials: The materials used in the construction of vertical axis pumps are particularly resistant to wear, corrosion and abrasion. Common materials include ductile cast iron, chromium cast iron, anti-abrasive NBR rubber and carbon steel.
Advantages:
- Small footprint: the vertical design allows the pump to be installed in tight spaces.
- Easy installation and maintenance: the vertical configuration facilitates access to internal components for maintenance.
- Energy efficiency: vertical axis pumps can be very energy efficient, especially those with metal impellers.
