Port column: the three Pro types are listed with G 1 in the Pro dimension drawing; the EH / QH dimension table in the datasheet does not state a port size (the PG9 / RC / QH suffixes are listed without explanation) – shown as "–". Net weight in kg.
Series technical data (from the datasheet's general technical section)
- Product type: Centrifugal pump; main hydraulic parts are the pump housing and impeller.
- Features: Compact design; low-noise operation; wide application for hot- and cold-water boosting and transfer.
- Motor protection: PTO (thermal overload protector) – the pump stops automatically when the stator winding temperature exceeds the limit and restarts when it falls back into range.
- Materials: Pump housing grey cast iron; impeller PPO/PS-GF30.
- Maximum operating pressure PN: 5 bar.
- Continuous-use conditions (series): Fluid temperature 0 to +90 °C; liquid pH 6.5–8.5; solid content ≤ 0.1 % (granule ≤ 0.2 mm); ambient temperature 0 to +40 °C; altitude < 1000 m; relative humidity < 90 %.
- Pump curves: Fluid medium Water 100 %, fluid temperature T = 20.00 °C (per model H/Q/Δp curves in the datasheet).
Note on absent data (no fabrication)
The datasheet does not state a mains voltage / frequency for any PUN model, nor an EAN, gross weight or certifications. These fields are therefore omitted from this page. Rated power P2, rated current IN, speed, efficiency class (IE2 for all except the IE3 PUN-751QH) and insulation / protection class are stated per model in the detailed table below.

Speed is the fixed 2-pole motor speed (1/min) as stated per model. Insulation class F for all 16 models. Protection class IP44 for the 15 EH/EAH types; the PUN-751QH (article 9160781) is the only IE3 / IP55 type. EAN: not stated in the datasheet (marked "–").
Materials
- Pump housing: Grey cast iron – for all 16 models (no stainless-steel variant exists in this series).
- Impeller: PPO / PS-GF30 (reinforced engineering plastic) – for all 16 models.
Material note (no stainless-steel housing in this series)
The Wilo PUN datasheet specifies a grey cast iron housing and a PPO/PS-GF30 impeller for every listed type. Do not assume a stainless-steel-housing version of any PUN model from this document.
Applications
- Water boosting: pressurising hot- and cold-water systems within the stated limits (fluid 0…+90 °C continuous, PN 5 bar).
- Water transfer: transferring clean water between tanks / circuits for residential and light-commercial use.
- General circulation: clean-water duty with pH 6.5–8.5, solid content ≤ 0.1 % and granule ≤ 0.2 mm, at altitude < 1000 m and RH < 90 %.
