Pedrollo JSW/JSWm Self-Priming Jet Pump – JSW1/JSW2/JSW3 Range, 230V/400V

The Pedrollo JSW/JSWm Self-Priming Jet Pump range draws water and liquids that contain air, making it well suited to domestic water distribution with small to medium-sized pressure tanks and general irrigation. The range spans three size tiers (JSW1, JSW2, JSW3) from 0.48kW up to 2.2kW, available in single-phase 230V (JSWm) or three-phase 400V (JSW) motor versions.

• Application: Domestic water distribution with pressure tanks, garden and general irrigation, civil water supply.
• Motor options: Single-phase 230V (JSWm range) or three-phase 400V (JSW range).
• Power range: 0.48kW (0.65HP) to 2.2kW (3HP) across three size tiers.
• Performance: Max head from 39.5m up to 97m depending on model and tier.
• Pump type: Self-priming jet pump – can draw water/air mixtures, unlike a standard centrifugal or peripheral pump.
• Motor efficiency: IE2 (single-phase) or IE3 (three-phase), per IEC 60034-30-1.

Key Features

• True self-priming operation: The jet/ejector design can draw water containing air, useful where the suction line isn't always fully flooded.
• Choice of motor: Single-phase 230V (JSWm) models work off a standard household supply; three-phase 400V (JSW) models suit properties or sites with a 3-phase electrical connection.
• Three size tiers: JSW1 (compact), JSW2 (mid-size), and JSW3 (higher head/flow) so you can match the pump to your system.
• JSW3 head tiers: The JSW3 range offers Medium (M) and High (H) head variants at the same power rating – confirm which tier you need before ordering.

Typical Applications

• Domestic water distribution with pressure/autoclave tanks
• General garden and irrigation use
• Civil and small commercial water supply
• Installations where the suction line may draw in air
