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 use. Therefore, it provides an efficient solution for irrigation, water transfer and abstraction from lakes, rivers and wells.
Moreover, its continuous-duty capability supports applications that require reliable operation over extended periods.
High-Flow Centrifugal Pump Design
The pump uses a single centrifugal impeller to move large quantities of water efficiently.
During operation, the rotating impeller accelerates the liquid inside the cast-iron pump casing. Consequently, the hydraulic design converts this velocity into usable flow and discharge pressure.
The HF high-flow centrifugal pump is particularly suitable where volume is more important than very high pressure.

Together, these features make the Pedrollo HF High Flow Pump suitable for high-volume water-transfer systems.
HF High Flow Pump Performance
The published HF High Flow 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 pump delivers 144 m³/h at 24.5 metres.
Instead, engineers must select the exact model according to the required flow and total system head.
Irrigation and Agricultural Applications
The Pedrollo HF High Flow Pump is well suited to agricultural applications that require large volumes of water.
Typical duties include:
- Furrow irrigation
- Sprinkler irrigation
- Field watering
- Crop irrigation systems
- Water transfer between reservoirs
- Agricultural storage-tank filling
- Water distribution across farms
Moreover, the high-flow design helps move water efficiently across systems with medium-low pressure requirements.
Water Abstraction from Natural Sources
The HF agricultural water pump can draw water from sources such as 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 across the range:
- AISI 304 stainless steel for HF 4 and HF 6
- Brass for HF 8
- Cast iron for HF 20 and HF 30
The pump cover also varies by configuration. Consequently, users should confirm the exact construction before selecting the Pedrollo HF High Flow Pump for a particular water quality or environment.
Operating Temperature and Pressure
The published operating limits include:
- Liquid temperature: -10°C to +90°C
- Maximum ambient temperature: +40°C
- Maximum working pressure: 6 bar for selected HF 4 models
- Maximum working pressure: 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 always take priority over the range-wide values.
Industrial Water-Transfer Applications
The Pedrollo HF High Flow Pump may support industrial applications that require substantial water flow at medium-low heads.
Potential duties include:
- Process-water circulation
- Cooling-water transfer
- Tank filling and emptying
- General plant water distribution
- Wash-water systems
- Water transfer between storage areas
- Civil water-supply systems
- Non-aggressive liquid transfer
Nevertheless, users must confirm that the liquid is compatible with the pump materials and does not contain damaging abrasive particles.
Efficient Continuous Operation
Pedrollo designed the range for efficient and continuous service. Therefore, the pump suits installations where dependable water movement is required for long operating periods.
However, correct sizing remains essential. A pump operating too far from its recommended duty point may consume unnecessary energy or experience increased mechanical stress.
Consequently, engineers should select the pump from its official performance curve rather than choosing it only by connection size or motor rating.
Installing the Pedrollo HF High Flow Pump
The pump should be installed in a dry, protected and adequately ventilated location.
In addition, the foundation should remain stable and level. The suction pipe should rise continuously towards the pump, while correctly sized valves and fittings should minimise pressure losses.
Because the pump is not self-priming, the pump casing and suction line must be filled before starting. Moreover, installers should prevent dry running because it may damage the mechanical seal and hydraulic components.
Choosing the Correct HF Pump
Correct selection depends on required flow, total dynamic head, suction conditions and operating hours.
Engineers should also confirm:
- Available electrical supply
- Liquid temperature
- Water quality
- Suction-pipe diameter
- Delivery-pipe losses
- Required working pressure
- Installation environment
- Impeller material
Therefore, specialists should select the Pedrollo HF High Flow Pump from model-specific hydraulic and construction data.
