Product Description
Pedrollo HF High Flow Pump
The Pedrollo HF High Flow Pump is a single-impeller centrifugal surface pump designed for applications that require substantial water flow at medium-low discharge heads.
Pedrollo developed the HF range for civil, agricultural and industrial applications. Therefore, it provides an efficient solution for irrigation, water transfer and abstraction from lakes, rivers and suitable wells across India.
Moreover, its continuous-duty capability supports systems that require dependable operation over extended periods.
High-Flow Centrifugal Pump Design
The pump uses a single centrifugal impeller to move large volumes of water efficiently.
During operation, the rotating impeller accelerates the liquid inside the cast-iron casing. Consequently, the hydraulic design converts this velocity into useful flow and discharge pressure.
The Pedrollo HF High Flow Pump particularly suits applications where water volume is more important than very high pressure.

Together, these features support high-volume water-transfer applications in agriculture, industry and civil systems.
HF High Flow Pump Performance
The published HF range delivers capacities up to 2,400 litres per minute, equivalent to 144 m³/h. Selected models also develop heads up to approximately 24.5 metres.
However, maximum flow and maximum head occur at different points on the hydraulic curve. Therefore, users should not assume that every model delivers 144 m³/h at 24.5 metres.
Instead, engineers should select the exact HF pump according to the required flow and total system head.
Irrigation and Agricultural Applications
The Pedrollo HF High Flow Pump suits agricultural systems that require large volumes of water.
Typical applications across India include:
- Furrow irrigation
- Sprinkler irrigation
- Field watering
- Crop irrigation systems
- Water transfer between reservoirs
- Agricultural tank filling
- Farm water distribution
Moreover, the high-flow design supports efficient water movement where medium-low pressure is sufficient.
Water Abstraction from Natural Sources
The HF agricultural water pump can draw water from lakes, rivers and suitable wells.
Its published manometric suction capability reaches up to approximately 7 metres. However, actual suction performance depends on pipe losses, water temperature, installation height and atmospheric conditions.
Therefore, installers should keep the suction line short, correctly sized and completely airtight.
Construction Materials
Pedrollo manufactures the pump casing from cast iron and the shaft from AISI 431 stainless steel.
However, the impeller material varies by model:
- AISI 304 stainless steel for HF 4 and HF 6
- Brass for HF 8
- Cast iron for HF 20 and HF 30
Consequently, users should confirm the exact construction before selecting the Pedrollo HF High Flow Pump for a particular water quality or operating environment.
Operating Limits
Published HF range limits include:
- Liquid temperature: -10°C to +90°C
- Maximum ambient temperature: +40°C
- Working pressure: Up to 6 bar for selected HF 4 models
- Working pressure: Up to 10 bar for HF 6, HF 8, HF 20 and HF 30
- Manometric suction head: Up to 7 metres
- Motor protection rating: IPX4
However, model-specific limits and installation instructions take priority over range-wide figures.
Industrial Water-Transfer Applications
The Pedrollo HF High Flow Pump may also support industrial and civil applications across India, including:
- Process-water circulation
- Cooling-water transfer
- Tank filling and emptying
- Plant water distribution
- Wash-water systems
- Storage-water transfer
- Civil water-supply systems
- Non-aggressive liquid transfer
Nevertheless, users should confirm that the liquid remains compatible with the pump materials and does not contain damaging abrasive solids.
Efficient Continuous Operation
Pedrollo designed the HF range for continuous service. Therefore, the pump suits installations that require reliable water movement for extended operating periods.
However, correct sizing remains essential. A pump operating too far from its recommended duty point may consume excess energy or experience increased mechanical stress.
Consequently, engineers should select the model from its official hydraulic performance curve rather than relying only on motor rating or connection size.
Installation Considerations
Install the Pedrollo HF pump in a dry, protected and adequately ventilated location.
In addition, use a stable, level foundation and correctly sized suction and delivery pipes to minimise hydraulic losses.
Because the pump is not self-priming, the pump casing and suction line require priming before startup. Moreover, operators should prevent dry running because it can damage the mechanical seal and hydraulic components.
Selecting the Correct Pedrollo HF Pump
Correct selection depends on:
- Required flow
- Total dynamic head
- Suction height
- Water source
- Liquid temperature
- Water quality
- Electrical supply
- Pipe diameter and losses
- Required working pressure
- Impeller material
Therefore, engineers should select the Pedrollo HF High Flow Pump from model-specific hydraulic and construction data.
