Product Description
Rovatti SK & SKD Series Pumps
The Rovatti SK & SKD Series Pumps are horizontal multistage centrifugal pumps designed for high-pressure water applications. Moreover, their rugged construction supports continuous operation in demanding municipal, agricultural and industrial systems.
The SK Series uses an axial suction inlet and a multistage bareshaft arrangement. Meanwhile, the SKD Series provides double bearing support for heavier hydraulic and mechanical duties.
Therefore, users can select the SK range for standard high-pressure applications or the SKD range for higher capacities, heads and power requirements.
High-Pressure Multistage Operation
Each impeller increases the liquid pressure before passing it to the next stage. Consequently, the total pressure rises progressively through the pump.
This multistage arrangement produces much higher heads than a typical single-stage centrifugal pump. Therefore, the range suits pressure boosting, long pipelines and systems with substantial elevation differences.
Moreover, centrifugal operation provides continuous flow. As a result, the pump delivers smooth water transfer without the strong pulsation associated with some positive-displacement technologies.

Together, these features support efficient and dependable high-pressure water transfer. Moreover, the broad performance range allows users to match the pump with different system requirements.
SK Series Performance
The Rovatti SK Series provides:
- Maximum flow: 300 m³/h
- Maximum head: 200 metres
- Maximum power: 130 kW
- Suction sizes: Approximately 50 to 150 mm
- Construction: Horizontal multistage bareshaft
- Inlet arrangement: Axial inlet
Therefore, the SK range suits irrigation, water supply, pressure boosting and washdown systems.
Moreover, users can select either a mechanical seal or packed gland. Consequently, the sealing arrangement can reflect the operating conditions and maintenance preference.
SKD Series Performance
The Rovatti SKD Series provides:
- Maximum flow: 540 m³/h
- Maximum head: 500 metres
- Maximum power: 330 kW
- Suction sizes: Approximately 65 to 150 mm
- Construction: Horizontal multistage bareshaft
- Bearing arrangement: Double bearing support
The additional bearing support improves shaft stability during demanding operation. Therefore, SKD models suit high-pressure duties involving substantial hydraulic and mechanical loads.
In addition, Rovatti offers several bearing-lubrication arrangements. As a result, operators can select an option that suits the operating environment and maintenance programme.
Single and Double Bearing Arrangements
SK Series Bearing Arrangement
The SK Series uses the standard support arrangement for its horizontal multistage configuration. Therefore, it provides a practical solution for moderate-to-high flow and pressure duties.
SKD Double Bearing Support
The SKD Series adds bearing support at both ends of the hydraulic assembly. Consequently, the design improves support for the shaft and rotating components.
Moreover, the double-support arrangement suits larger pumps and higher-stage configurations. As a result, SKD models can achieve considerably higher heads than the standard SK range.
Shaft-Sealing Options
Rovatti offers mechanical-seal and packed-gland configurations.
A mechanical seal reduces routine leakage around the shaft. Therefore, it suits installations where cleaner operation is important.
Alternatively, a packed gland provides an adjustable sealing arrangement. Moreover, selected packed-gland versions use Rovatti’s Twinner System® to simplify inspection and maintenance.
However, the correct sealing system depends on water quality, pressure, temperature and site maintenance practices.
Rovatti SK & SKD Applications in the UAE
The range suits:
- Municipal water supply
- Industrial water distribution
- Pressure-boosting stations
- Irrigation networks
- High-pressure washdown systems
- Long-distance water transfer
- Tank and reservoir filling
- General industrial processes
- District and utility water systems
- Snow-making systems
- Fire-water boosting where project requirements permit
For example, an SK pump can support an agricultural pressure-boosting system. Similarly, an SKD pump can serve a high-head industrial or municipal water network.
Selecting the Correct Pump
Correct selection depends on:
- Required flow
- Total dynamic head
- Number of stages
- Available NPSH
- Liquid temperature
- Water quality
- Motor speed and power
- Shaft-seal preference
- Bearing-lubrication requirements
- Suction and discharge pipe sizes
Therefore, users should select the pump from the individual Rovatti performance curve. Otherwise, the unit may operate away from its best efficiency range.
Why Choose Rovatti SK & SKD Pumps?
The SK and SKD ranges combine high-pressure multistage hydraulics with durable construction. Moreover, they provide flexible sealing, bearing and model options.
Therefore, they are strong choices for UAE projects that require reliable high-head operation, continuous flow and long-term industrial performance.
