Pedrollo PKm Series
Pedrollo PK Series – Reliable Peripheral Impeller Pumps for Domestic Applications
The Pedrollo PK Series features compact and efficient peripheral impeller pumps designed for clean water use in domestic applications. These pumps are ideal where consistent pressure and modest flow are required. Their performance and durable design make them a preferred transfer pump for household systems.
Compact and Practical Design
The PK Series stands out due to its compact size and efficient layout. Each pump uses a peripheral impeller to generate flow and pressure. This design allows high pressure delivery from a small, lightweight frame.
Because of the compact structure, installation is easy in tight utility spaces or mechanical rooms. These pumps integrate well into small-scale water systems without needing complex support equipment.
Built for Long-Term Performance
Pedrollo uses strong and reliable materials throughout the PK Series. The pump body is made of durable cast iron with corrosion-resistant treatment. This material ensures strength and protection from rust or wear.
The impeller is made from high-quality brass, which handles heat, pressure, and frequent cycling. This brass impeller resists deformation under load and ensures long pump life. Additionally, the motor shaft is built from stainless steel, offering added strength and corrosion resistance.
Reliable Motor and Power Options
Each PK pump features an asynchronous, air-cooled motor built for continuous use (S1 duty). Pedrollo offers both single-phase and three-phase motors, depending on user needs.
Most domestic applications use single-phase models operating at 230V. Larger systems benefit from three-phase units that run on 230/400V. Single-phase units include built-in thermal protection to prevent overheating or electrical damage.
These motors are efficient and require very little maintenance. Their reliability makes them an ideal choice for long-term use in homes.
Peripheral Impeller Efficiency
Unlike centrifugal designs, peripheral impeller pumps use a toothed impeller that spins water around a channel. This method increases pressure even at low flow rates.
The PK Series provides maximum head up to 80 meters, depending on the model. This makes it ideal for systems needing high pressure, such as domestic showers or long pipe runs.
Although flow rates remain moderate, the pressure delivery is smooth and reliable. These features make the PK Series excellent for pressure boosting in homes and gardens.
Versatile Domestic Applications
Pedrollo designed the PK Series for a wide range of domestic applications. These include:
Boosting water pressure in homes
Transferring water from storage tanks
Filling garden irrigation systems
Supplying small domestic water heaters
Supporting cooling and washing systems
Because of their high-pressure capability, these pumps perform well where mains water pressure is too low. The transfer pump function is also excellent for moving clean water over long distances.
Effective Suction and Flow Capabilities
These pumps can lift water from depths of up to 8 meters. However, they are not self-priming, so initial priming is required. Installing a foot valve ensures the suction pipe remains filled after shutdown.
Once primed, the pump provides steady, consistent suction and discharge. This makes it effective for tank transfers or pulling water from shallow wells or cisterns.
Quiet and Energy-Efficient Operation
Pedrollo PK pumps operate quietly, making them perfect for indoor setups. Their compact size also reduces vibration and noise. This quiet performance is important in domestic environments.
Additionally, the peripheral impeller pump design ensures energy-efficient operation. Less power is needed to generate strong pressure, which lowers running costs over time.
These pumps are ideal when you need pressure without excessive energy use.
Simple Installation and Maintenance
Thanks to their small size and lightweight construction, PK pumps are easy to install. Basic plumbing and electrical connections are all that’s needed. No complex accessories are required.
Routine maintenance includes checking the impeller, seals, and electrical connections. Cleaning the suction line regularly also helps maintain optimal performance. When needed, most parts are easy to replace.
Pedrollo offers strong after-sales support and replacement part availability. This ensures the pump remains functional over many years.
Popular Models in the PK Series
Pedrollo’s PK line includes several models to match different performance needs. Examples include:
PKm 60 – 0.37 kW; ideal for light household tasks
PKm 65 – 0.5 kW; suitable for pressure boosting
PKm 70 – 0.55 kW; good for irrigation and small tank fills
PKm 80 – 0.6 kW; delivers higher pressure output
PKm 90 – 0.75 kW; used for longer pipe systems
All models with the “m” suffix are single-phase and fit standard home power systems. Three-phase versions are also available for larger or shared systems.
Weather Protection and Usage Guidelines
All PK pumps carry IP44 or IP54 protection ratings, depending on the motor. These ratings shield the unit from dust and water splashes. However, outdoor installations must include a protective pump cover or housing.
It’s best to install the pump in a clean, ventilated space. Avoid exposing the motor to moisture, freezing conditions, or direct sunlight.
