Overview of Pedrollo PKm80 Peripheral Impeller Pump
The Pedrollo PKm80 is a part of the PK range of peripheral impeller booster pumps, designed to transfer clean water free from abrasive particles and liquids that will not damage the pump’s components. These robust, reliable, and economical pumps are principally used for water boosting in domestic and small-scale water transfer applications where there is insufficient mains pressure available.
The pump body is made of cast iron with an inset brass impeller facing for improved starting performance. They can be installed for manual operation or for automatic control using either a pressure tank and switch or the unique ‘Presscontrol’ unit. The PKm80 model offers a flow rate up to 90 l/min (5.4 m3/h), a head up to 100 m, and a manometric suction head up to 8 m.

How does Pedrollo PKm80 Peripheral Impeller Pump work?
The Pedrollo PKm80 Peripheral Impeller pump operates on the principle of peripheral impeller action. The pump has an impeller with many radial vanes on its outer edge. As the impeller rotates within a concentric channel of the casing, the liquid flows between the vanes and the casing. This rotation transfers a large amount of energy to the liquid, leading to an increase in pressure inside the pump. Unlike standard centrifugal pumps, the pressure curves of peripheral pumps do not flatten as the fluid flow decreases. This means that the fluid moves along the circumference from the inlet to the outlet of the casing with increasing pressure.
The pumps are close-coupled to a Totally Enclosed Fan Cooled (TEFC) brushless induction motor designed for continuous operation. A thermal relay is provided in the windings to protect against electrical and mechanical overload. The pump can be connected directly to the mains power supply through a 10amp fuse or Miniature Circuit Breaker (MCB). This design ensures that the pump operates reliably and efficiently, making it ideal for applications that require high discharge heads at low flow rates.
Exclusive features and benefits of Pedrollo PKm80 Peripheral Impeller Pump
The Pedrollo PKm80 Peripheral Impeller pump offers several exclusive features and benefits:
- High Efficiency: The pump is designed with a compact and efficient motor that consumes low energy and operates at a lower temperature. This results in cost savings and environmental benefits.
- High Performance: The pump can achieve high heads from low motor powers and has a high tolerance to entrained air in the pumped liquid. This makes it suitable for a wide range of applications.
- Self-Priming: The pump is self-priming, making it effective in drawing water from tanks and pumping liquids that contain air or gas.
- Quiet Operation: The pump operates quietly due to the anti-vibration system between the shaft and impeller.
- Corrosion Resistance: The pump is coated with a special paint that provides improved resistance against environmental corrosion.
- Versatility: The pump is suitable for a variety of domestic applications, including water distribution in combination with small pressure sets, garden irrigation, and drawing water from tanks.
- Reliability: The pump is reliable and easy to operate, making it an ideal choice for domestic and small-scale water transfer applications.
- Safety: The pump comes complete with a flap-check valve, and a thermal relay is provided in the windings to protect against electrical and mechanical overload.

Pedrollo PKm80 Peripheral Impeller Pump components
The Pedrollo PKm80 Peripheral Impeller pump is composed of several key components:
- Pump Body: The pump body is made of cast iron, complete with threaded ports in compliance with ISO 228/1. This provides a robust and durable structure for the pump.
- Motor Bracket: The motor bracket is made of aluminum with a brass insert. This patented design reduces difficulties when starting the pump after long periods without use.
- Impeller: The impeller is made from brass, with radial peripheral blades. It floats on the shaft, which reduces the risk of the impeller locking after long periods of inactivity.
- Motor Shaft: The motor shaft is made of stainless steel EN 10088-3 – 1.4104. This provides strength and durability to the pump.
- Mechanical Seal: The mechanical seal is made of different materials depending on the model of the pump. For example, the PK 60-65 model uses ceramic and graphite, while the PK 90 model uses silicon carbide and graphite.
- Bearings: The bearings used in the pump vary depending on the model. For instance, the PK 60-65 model uses 6201 ZZ / 6201 ZZ bearings, while the PK 70-80-90 model uses 6203 ZZ / 6203 ZZ bearings.
- Capacitor: The pump uses a capacitor for single-phase operation. The capacitance varies depending on the voltage.
