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. It combines efficient hydraulic performance with the ability to operate continuously when correctly selected and installed.
Therefore, the range suits systems requiring substantial flow at medium-low head pressures. 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 the velocity of the water. The casing then converts this velocity into usable flow and discharge pressure.
Consequently, the pump provides an effective balance between water volume and head. It is particularly suitable where a moderate flow rate and higher head than the HF High Flow range are required.
Main Features and Benefits
- 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

- IPX4 motor protection
Together, these characteristics make the Pedrollo HF Medium Flow Pump suitable for dependable irrigation and water-transfer installations.
Pedrollo HF Medium Flow Pump Performance
The complete 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 operating points. Therefore, users should not assume that every configuration delivers 42 m³/h at 39 metres.
Instead, engineers should select the precise model from its official hydraulic curve according to the required flow and total dynamic head.
Irrigation and Agricultural Applications
The HF centrifugal pump suits agricultural systems that require consistent water delivery over extended operating periods.
Common applications include:
- Furrow irrigation
- Sprinkler irrigation
- Field watering
- Crop-irrigation networks
- Agricultural tank filling
- Reservoir-to-reservoir transfer
- Farm water distribution
- Greenhouse irrigation systems
Moreover, the available head makes the range suitable for installations with pipeline resistance, elevation changes or sprinkler-pressure requirements.
Drawing Water from Lakes, Rivers and Wells
The Pedrollo HF Medium Flow Pump can draw water from lakes, rivers and suitable wells when used with a correctly designed suction system.
Pedrollo publishes a manometric suction head of up to approximately 7 metres. However, actual suction capability depends on altitude, water temperature, pipe diameter, friction losses and installation height.
Therefore, installers should keep the suction line short, airtight and correctly sized. They should also install a suitable foot valve and strainer where the application requires them.
Construction of the Pedrollo HF Medium Flow Pump
Pedrollo manufactures the pump casing from cast iron, providing mechanical strength for fixed civil and agricultural installations.
The impeller uses AISI 304 stainless steel, while the pump shaft uses AISI 431 stainless steel. Consequently, the primary rotating components provide reliable mechanical and corrosion resistance.
The pump cover is generally AISI 304 stainless steel. However, selected HF 5M and HF 70 configurations use a cast-iron pump cover. Therefore, buyers should confirm the exact materials for the selected model.
HF Medium Flow Operating Limits
Published operating 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
These values describe the complete range. Consequently, model-specific technical data must determine the final installation limits.
Industrial Water-Transfer Applications
The Pedrollo HF Medium Flow Pump can also support industrial applications requiring substantial water flow at medium-low heads.
Potential duties include:
- 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
However, the pumped liquid must remain compatible with the casing, impeller, shaft and sealing materials.
Continuous and Efficient Operation
Pedrollo designed the HF range for high efficiency and continuous operation. Therefore, it suits applications where reliable water delivery is required for long working periods.
Nevertheless, the pump should operate within its recommended hydraulic range. Running too far from the correct duty point can increase energy consumption, vibration and mechanical stress.
As a result, accurate system calculations remain important for both efficiency and service life.
Installing the Pedrollo HF Medium Flow Pump
Install the pump in a dry, protected and adequately ventilated position. Moreover, mount it on a stable, level foundation to minimise vibration and maintain shaft alignment.
Because this is a conventional centrifugal surface pump, the pump casing and suction pipe must be filled before starting. Therefore, installers must prevent dry running, which may damage the mechanical seal and hydraulic components.
Correctly sized pipework, gradual bends and minimal restrictions also help maintain the required performance.
Choosing the Correct Pedrollo HF Medium Flow Pump
Correct selection depends on required flow, total dynamic head, suction height and operating hours.
Engineers should also confirm:
- Electrical supply
- Liquid temperature
- Water quality
- Suction-pipe diameter
- Delivery-pipeline losses
- Required working pressure
- Installation environment
- Preferred model construction
Therefore, specialists should select the exact pump from model-specific hydraulic and dimensional information.
