Note on absent data (no fabrication)
The datasheet does not state an EAN for any PW model, nor a specific efficiency-index value (it only describes "high-efficiency motors IE" at series level) or certifications. These fields are therefore omitted from this page. Rated power P2, rated current IN, speed, insulation and protection class are stated per model in the detailed table below.

| PW-S600EH | 9194832 | – | 1~220 V, 50 Hz | 0.6 kW | 3.63 A | 2840 | F | IP44 | 6 | G 1 | 13.2 / 15.0 |

Insulation class F and protection class IP44 for all 8 models. Net / gross weight in kg. EAN: not stated in the datasheet (marked "–"). The two S75x types run at PN 7 bar with a G 1¼ port; the other six run at PN 6 bar with a G 1 port.
Materials
- Pump housing: Grey cast iron EN-GJL-200 – for all 8 models (no stainless-steel-housing version exists in this series).
- Impeller: Brass (CW617N).
- Impeller cover: Brass.
- Shaft: Stainless steel 1.4006 (note: the shaft only – not the housing).
- Mechanical seal: Carbon / Ceramic.
- Terminal box cover: ABS.
Material note (stainless steel is the shaft only, never the housing)
The Wilo PW datasheet specifies a grey cast iron housing (EN-GJL-200) and a brass impeller for every listed type. Stainless steel 1.4006 is used for the shaft only. Do not read this as a stainless-steel pump housing – there is no such variant in this series.
Performance curves (from the datasheet's pump curves, Water 100 %, T = 20 °C)
| Model | Flow Q range | Head H range |
|---|---|---|
| PW-S406EH | 0 – 1.4 m³/h | 39 – 25 m |
| PW-S600EAH / PW-S600EH | 0 – 1.1 m³/h | 43 – 32 m |
| PW-S751EAH / PW-S753EH | 0 – 3.6 m³/h | 52 – 7 m |
These Q/H ranges are printed in the datasheet for the models above; the remaining types share the same peripheral-pump curve family (Water 100 %, 20 °C) in the document.
Applications
- Water supply from a water tank: drawing water from a cistern / tank for domestic supply.
- Sprinkling & irrigation: garden / agricultural sprinkling and spraying from a tank.
- Rainwater utilisation: pumping harvested rainwater from a tank for non-potable use.
