Product Description
Rovatti SNE Series Pumps
The Rovatti SNE Series Pumps are horizontal, single-stage bareshaft centrifugal pumps for demanding water-transfer applications. Moreover, their standardised design complies with EN 733 and DIN 24255 dimensional requirements.
The pumps use an axial suction inlet and a volute-shaped discharge casing. Consequently, liquid enters the impeller smoothly before moving towards the discharge connection.
The detailed Rovatti range delivers capacities up to 1,300 m³/h. In addition, selected models provide heads up to 155 metres and operating speeds up to 3,500 rpm.
High-Efficiency Centrifugal Performance
The SNE Series uses a single-stage centrifugal hydraulic design. During operation, liquid enters through the axial inlet and reaches the centre of the impeller.
The rotating impeller then increases the liquid’s velocity. Afterwards, the volute casing converts part of that velocity into pressure.
As a result, the pump provides continuous and stable flow. Moreover, Rovatti positions the SNE range among its high-efficiency surface-pump solutions.

Together, these features support efficient and dependable water movement. Moreover, the broad range allows users to select a pump for different flow, head and connection requirements.
SNE Series Performance Range
The detailed SNE product range includes the following principal sizes:
- SNE32: Up to 51 m³/h
- SNE40: Up to 84 m³/h
- SNE50: Up to 120 m³/h
- SNE65: Up to 210 m³/h
- SNE80: Up to 345 m³/h
- SNE100: Up to 560 m³/h
- SNE125: Up to 600 m³/h
- SNE150: Up to 780 m³/h
- SNE200: Up to 960 m³/h
- SNE250: Up to 1,300 m³/h
However, maximum flow and maximum head do not occur at the same operating point. Therefore, users must select the pump from the individual performance curve for the required flow and total dynamic head.
Back Pull-Out Design
The SNE Series uses a back pull-out arrangement. Therefore, technicians can remove the rotating assembly without disconnecting the main pump casing from the pipework.
As a result, maintenance teams can access the impeller, shaft, bearings and sealing components more efficiently.
Moreover, this design can reduce maintenance time in installations where large suction and discharge pipes are difficult to remove.
Mechanical Seal and Packed-Gland Options
The Rovatti SNE Series is available with either a mechanical seal or packed gland.
Mechanical Seal
A mechanical seal provides controlled shaft sealing for many water and industrial applications. Consequently, it helps reduce routine leakage around the shaft.
Packed Gland
Alternatively, packed-gland configurations suit applications where users prefer adjustable packing and controlled lubrication leakage.
Moreover, packed-gland SNE models can use Rovatti’s Twinner System®. This system is designed to simplify inspection, cleaning and maintenance of the sealing area.
Standardised Pump Dimensions
EN 733 standardisation defines key pump dimensions and duty conventions. Therefore, the SNE Series can simplify installation, replacement and system design.
In addition, standardised suction and discharge arrangements help consulting engineers compare pump options more effectively.
However, larger SNE models may extend beyond the dimensional range normally covered by EN 733. Consequently, users should verify the exact dimensional drawing for the selected model.
Rovatti SNE Applications in the UAE
The Rovatti SNE Series Pumps suit:
- Industrial water supply
- Firefighting systems
- Cooling-water circulation
- Air-conditioning systems
- Irrigation networks
- Municipal water distribution
- General liquid transfer
- Process-water systems
- Tank and reservoir filling
- District cooling facilities
- Manufacturing plants
- Water-treatment facilities
For example, industrial plants can use the pumps for cooling-water circulation. Similarly, firefighting systems can use correctly selected models for dependable water delivery.
Moreover, the broad capacity range supports both moderate and high-flow installations.
Selecting the Correct SNE Pump
Correct selection depends on:
- Required flow rate
- Total dynamic head
- Available NPSH
- Liquid temperature
- Liquid density and viscosity
- Suction and discharge pipe sizes
- Motor speed and power
- Seal preference
- Installation and maintenance requirements
Therefore, users should select the pump from Rovatti’s individual hydraulic curves. Otherwise, the unit may operate away from its best efficiency point.
Why Choose Rovatti SNE Series Pumps?
The SNE Series combines high hydraulic efficiency with standardised construction. Moreover, its back pull-out arrangement and multiple sealing options simplify maintenance planning.
Therefore, it is a strong choice for UAE projects requiring efficient, durable and serviceable horizontal centrifugal pumps.
