Pedrollo PKM/PK Peripheral Impeller Pump – 230V/400V, 0.37–2.2kW

The Pedrollo PKM/PK Peripheral Impeller Pump range is a reliable line of self-priming pumps built for high-pressure, moderate-flow water applications. The range covers seven power sizes from 0.37kW to 2.2kW, and is available in single-phase 230V (PKm) or three-phase 400V (PK) motor versions. It suits domestic water supply, borehole and tank transfer, garden irrigation and small commercial pressure-boosting systems where high head is needed rather than high flow. The PKM60 is also available bundled with an Aquasystems pressure tank.

• Application: Domestic water supply, borehole/tank transfer, garden irrigation, small commercial pressure-boosting.
• Motor options: Single-phase 230V (PKm range) or three-phase 400V (PK range).
• Power range: 0.37kW (0.50HP) to 2.2kW (3HP) across 7 model sizes.
• Performance: Max head from 40m up to 100m depending on model, for high-pressure duty at moderate flow.
• Pump type: Peripheral (regenerative) impeller design, self-priming.
• Motor efficiency: IE2 or IE3 three-phase motor class (IEC 60034-30-1), depending on model.

Key Features

• Peripheral impeller design: Generates high head at relatively low flow rates, making it well suited to pressure-boosting duty rather than high-volume transfer.
• Choice of motor: Single-phase 230V (PKm) models work off a standard household supply; three-phase 400V (PK) models suit properties or sites with a 3-phase electrical connection.
• Seven size options: Sized from 0.37kW up to 2.2kW so you can match the pump to your required head and flow rather than over- or under-sizing.
• Self-priming operation: Able to draw water from below pump level without needing to be manually primed on start-up (within the pump's rated suction capability).

Typical Applications

• Domestic pressure boosting for household water supply
• Borehole-to-tank or tank-to-house water transfer
• Garden and small-scale irrigation systems
• Farm and smallholding water supply
• Small commercial systems requiring high head at moderate flow

Technical Specifications

Performance figures are read from the manufacturer's Q/H curve at the flow points supplied and are for guidance only. Tolerance of characteristic curves complies with EN ISO 9906 Grade 3B.

Configuration Options

Most models are sold as "Pump Only". The PKM60 is also available bundled with a 25L Aquasystems pressure tank for autoclave-style installations. Confirm exact kit contents with Zisabo before ordering.

What's Included

• 1 x Pedrollo peripheral impeller pump (model and phase as selected)
• Plus the tank listed in the Configuration option, where selected

Please note: Installation fittings, electrical protection, control boxes, cartridges, control boxes, cables, unions, brackets, or accessories are not included unless specifically listed above.

Installation & Compatibility Notes

• Confirm your required flow rate and head against the table above before ordering – this range is built for high pressure at moderate flow, not high-volume transfer.
• Single-phase 230V (PKm) models run off a standard household supply. Three-phase 400V (PK) models require a 3-phase electrical connection and installation by a qualified electrician.
• Peripheral impeller pumps are designed for clean water only and are not suited to water containing sand, solids, or debris.
• Confirm connection size and pipe compatibility with Zisabo before ordering.
• Qualified installation is recommended, particularly for three-phase wiring, electrical protection, and any control box requirements.
