Overview: What is the Wilo PUN series

At a glance: The Wilo PUN is a range of centrifugal pumps with a compact design and low-noise operation, intended for boosting and water transferring of hot and cold water. The range comprises 16 models – three Pro types (Pro-200EAH, Pro-600EAH, Pro-750EAH) and thirteen EH / QH types (201EH–751EH in PG9 / RC connection variants, plus the 751QH). Rated motor power P2 ranges from 0.2 kW to 0.75 kW, rated current from 1.83 A to 5.1 A, and the maximum operating pressure is PN 5 bar for all types. The pump housing is grey cast iron and the impeller is PPO/PS-GF30 across the whole range – there is no stainless-steel-housing version in this series. (All data below is taken verbatim from the Wilo product datasheet; fields the datasheet does not list – e.g. mains voltage / frequency, EAN, gross weight, head/flow duty values and certifications – are intentionally omitted, not estimated.)

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 %.

FAQ

Does the Wilo PUN series include any stainless-steel-housing model?
No. The Wilo PUN datasheet specifies a grey cast iron housing and a PPO/PS-GF30 impeller for all 16 models (articles 9226094–9226096 and 9118413–9247275 / 9160781). There is no stainless-steel-housing version in this series.
What are the power and pressure ratings of the PUN series?
Rated motor power P2 is 0.2 kW, 0.6 kW or 0.75 kW and rated current 1.83–5.1 A across the 16 types; the maximum operating pressure is PN 5 bar for every model. The PUN-751QH (article 9160781) is the only IE3 / IP55 type; all other 15 types are IE2 / IP44.
Why is there no mains voltage / frequency listed for these pumps?
The Wilo PUN datasheet provides rated power P2, rated current IN, speed, efficiency class, insulation and protection class for every type, but does not state a mains voltage or frequency. To avoid fabricating a value, no mains-connection column is included on this page.
