Product Description
Electric Submersible Pump with Double-Channel Impeller
The Electric Submersible Pump with Double-Channel Impeller provides dependable, high-capacity pumping for wastewater, stormwater and liquids containing solids or fibres. Rovatti developed the RH150B series for demanding wet installations where conventional drainage pumps may not provide enough solids-handling capacity.
Moreover, the double-channel impeller combines efficient hydraulic performance with a large free passage. Therefore, the pump can transfer wastewater and suspended materials while reducing the likelihood of blockage.
The pump operates completely submerged in the liquid. As a result, it does not require a separate suction system or priming arrangement.
Reliable Wastewater and Stormwater Handling
The Electric Submersible Pump with Double-Channel Impeller suits applications that require both substantial flow and large solids passage. Its double-channel hydraulic design moves wastewater through two defined impeller channels.
Consequently, the pump provides a practical solution for stormwater collection, livestock drainage, fish farming and general dewatering. However, operators should still prevent metal pieces, stones and oversized debris from entering the wet well.
Correct model selection also remains essential. Therefore, engineers should assess flow, total head, solids dimensions and discharge pipework before installation.
Flexible Wet Installation Options
Free-Standing Wet Installation
Users can install the double-channel wastewater pump directly on the bottom of a tank, sump or wet well.
Furthermore, the pump can connect to either rigid or flexible discharge pipework. This arrangement suits temporary pumping, accessible drainage pits and installations where operators may need to reposition the unit.
Automatic Coupling-Foot Installation
Alternatively, users can install the Electric Submersible Pump with Double-Channel Impeller on an automatic coupling foot.
In this arrangement, guide rails allow technicians to lower the pump onto the discharge connection from ground level. Therefore, they can remove the pump for inspection or maintenance without entering the wet well.
As a result, automatic coupling installation offers practical benefits for permanent wastewater and stormwater pumping stations.
Published RH150B Performance
Rovatti publishes the following maximum specifications for the RH150B series:
- Capacity up to 475 m³/h
- Head up to 25 metres
- Power up to 18.5 kW
- Solids passage of 125 × 140 mm
- Double-channel impeller
- Free-standing or automatic coupling-foot installation
Therefore, this electric wastewater pump can support high-capacity duties with large suspended solids. Nevertheless, engineers should select the final operating point from the official performance curve rather than relying only on maximum values.
Advantages of the Double-Channel Impeller
The double-channel impeller provides defined passages for wastewater and suspended materials. Consequently, it can deliver efficient liquid transfer while maintaining a large free passage.
In addition, the two-channel arrangement suits applications that require a balance between solids handling and hydraulic efficiency.
However, the pumped materials must remain within the pump’s published passage limits. Oversized or unsuitable objects may still obstruct or damage the hydraulic components.
Typical UAE Applications
The Electric Submersible Pump with Double-Channel Impeller suits:
- Stormwater collection systems
- Livestock drainage installations
- Fish farming and aquaculture
- General dewatering
- Wastewater collection pits
- Agricultural wastewater systems
- Commercial drainage facilities
- High-capacity wet wells
- Floodwater management
- Permanent wastewater pumping stations
Rovatti officially identifies livestock systems, fish farming, stormwater collection and dewatering as primary applications for this product range.
Pump Selection Considerations
Users should select and configure the pump according to:
- Required operating flow
- Total dynamic head
- Maximum solids dimensions
- Wastewater characteristics
- Wet-well depth and dimensions
- Discharge pipe diameter
- Available electrical supply
- Installation method
- Operating frequency
- Maintenance access
Moreover, permanent pumping stations may require level sensors, a control panel, non-return valves, isolation valves and guide rails.
Therefore, a complete system assessment can prevent motor overload, poor hydraulic performance and excessive energy use.
