Product Description
Pedrollo HF Medium Flow Pump
The Pedrollo HF Medium Flow Pump is a single-impeller centrifugal surface pump for civil, agricultural and industrial water-transfer applications across India. It combines efficient hydraulic performance with continuous-duty capability when correctly selected and installed.
Therefore, the range suits systems requiring substantial flow at medium-low heads. Typical duties include furrow irrigation, sprinkler irrigation and drawing water from rivers, lakes and suitable wells.
HF Medium-Flow Centrifugal Design
The pump uses a single centrifugal impeller inside a durable cast-iron casing. During operation, the rotating impeller increases water velocity, while the casing converts that velocity into usable flow and discharge pressure.
Consequently, the Pedrollo HF Medium Flow Pump provides an effective balance between water volume and head. It particularly suits applications requiring moderate flow with greater head than the HF High Flow range.
Key Features and Benefits
The Pedrollo HF Medium Flow range provides:
- Single-impeller centrifugal construction
- Flow rate up to 700 l/min
- Maximum capacity up to 42 m³/h
- Maximum head up to 39 metres
- Manometric suction head up to 7 metres
- Continuous-duty capability
- Two-pole electric motor
- Cast-iron pump casing

- IPX4 motor protection
Together, these features support dependable irrigation, water-transfer and general civil applications.
Pedrollo HF Medium Flow Pump Performance
The range delivers flow rates up to approximately 700 litres per minute, equivalent to 42 m³/h. Selected models also develop discharge heads up to approximately 39 metres.
However, maximum flow and maximum head occur at different points on the hydraulic curve. Therefore, users should not assume that every model delivers 42 m³/h at 39 metres.
Instead, engineers should select the exact pump according to the required flow and total dynamic head.
Irrigation and Agricultural Applications
The Pedrollo HF Medium Flow Pump suits agricultural systems that require consistent water delivery over extended operating periods.
Typical applications across India include:
- Furrow irrigation
- Sprinkler irrigation
- Field watering
- Crop-irrigation networks
- Agricultural tank filling
- Reservoir-to-reservoir transfer
- Farm water distribution
- Greenhouse irrigation
Moreover, its available head can support systems with pipeline resistance, elevation changes or sprinkler-pressure requirements.
Water Abstraction from Lakes, Rivers and Wells
The Pedrollo HF centrifugal pump can draw water from lakes, rivers and suitable wells when installed with a correctly designed suction system.
Pedrollo publishes a manometric suction head of up to approximately 7 metres. However, actual suction performance depends on altitude, water temperature, pipe diameter, friction losses and installation height.
Therefore, installers should keep the suction line short, airtight and correctly sized. In addition, a suitable foot valve and strainer may be required depending on the application.
Pump Construction
Pedrollo manufactures the casing from cast iron for mechanical strength in fixed civil and agricultural installations.
The impeller uses AISI 304 stainless steel, while the shaft uses AISI 431 stainless steel. Consequently, these rotating components provide dependable mechanical strength and corrosion resistance.
The pump cover generally uses AISI 304 stainless steel. However, selected HF 5M and HF 70 configurations use a cast-iron cover. Therefore, users should confirm model-specific materials before selection.
HF Medium Flow Operating Limits
Published range-wide limits include:
- Maximum flow: Up to 700 l/min or 42 m³/h
- Maximum head: Up to 39 metres
- Manometric suction head: Up to 7 metres
- Liquid temperature: -10°C to +90°C
- Maximum ambient temperature: +40°C
- Maximum working pressure: Up to 6 or 10 bar, depending on model
- Motor speed: Two-pole
- Motor protection: IPX4
However, model-specific technical data should determine the final installation limits.
Industrial Water-Transfer Applications
The Pedrollo HF Medium Flow Pump can also support industrial and civil water duties across India, including:
- Process-water transfer
- Cooling-water circulation
- Storage-tank filling
- Wash-water distribution
- Civil water-supply systems
- Water transfer between plant areas
- General industrial water movement
- Compatible non-aggressive liquid transfer
Nevertheless, users should confirm that the liquid remains compatible with the casing, impeller, shaft and sealing materials.
Continuous and Efficient Operation
Pedrollo designed the HF range for continuous operation. Therefore, it suits applications where dependable water delivery is required for long working periods.
However, the pump should operate within its recommended hydraulic range. Running too far from the correct duty point may increase energy consumption, vibration and mechanical stress.
Consequently, accurate system calculations help improve both efficiency and service life.
Installation Considerations
Install the Pedrollo HF Medium Flow Pump in a dry, protected and adequately ventilated position. Moreover, use a stable, level foundation to minimise vibration.
Because this is a conventional centrifugal surface pump, the casing and suction pipe require priming before startup. Therefore, operators should prevent dry running because it may damage the mechanical seal and hydraulic components.
Correctly sized pipework, gradual bends and minimal restrictions also help maintain pump performance.
Selecting the Correct Pedrollo HF Medium Flow Pump
Correct selection depends on:
- Required flow
- Total dynamic head
- Suction height
- Water source
- Liquid temperature
- Water quality
- Electrical supply
- Pipeline losses
- Required working pressure
- Installation environment
Therefore, engineers should select the Pedrollo HF Medium Flow Pump from model-specific hydraulic and dimensional data.
