LEO LRP32-50/180
Model in the LRP Hot Water Circulation Pump Range.
50 Hz reference specifications
For heating and HVAC water circulation. Confirm liquid compatibility and any potable-water approval requirements before selection. These values reproduce LEO's published European 50 Hz sheet; confirm the supplied version and required duty before ordering.
| Item | Published reference |
|---|---|
| Electrical supply | 220–240 V / 50 Hz |
| Motor control | Three speed settings (3 / 2 / 1) |
| Insulation / enclosure | Class H / IP44 |
| Liquid temperature | 2–110 °C |
| Body / connection | Cast-iron body, threaded-connection version. |
Published speed ratings — LRP32-50/180
| Speed | Electrical power (W) | Maximum flow (L/min) | Maximum head (m) |
|---|---|---|---|
| 3 | 73 | 63 | 5.2 |
| 2 | 65 | 54 | 4.9 |
| 1 | 42 | 35 | 3.7 |
Maximum flow and maximum head are separate limits, not a simultaneous operating point. They have not been joined to invent a performance curve.
Individual hydraulic curve and dimensions
The original manufacturer plot is reproduced with its axes, model legend and speed settings. Blue Q–H lines use the head axis; orange Q–P lines use the electrical-power axis. Shared legends are retained where the manufacturer explicitly groups models. No numerical flow–head table, fitted points or extrapolation has been invented.
Product dimensional data
| Drawing symbol | Model value |
|---|---|
| L | 180 mm |
| B | 125 mm |
| B1 | 75 mm |
| H | 135 mm |
| H1 | 30 mm |
| G | G2 |
Symbols follow the manufacturer dimension drawing. L is the installation length between connections. G is the thread callout, not a metric dimension or a guarantee of union accessories. D symbols apply to flanged versions. Package sizes have not been substituted for product dimensions.
Source-version and duty confirmation
The manufacturer's tabular speed maxima and drawn curve intercepts do not always agree. Both are reproduced as published rather than silently reconciled; the applicable supplied version and accepted duty point require confirmation.
Electrical-rating conflict: the local LEO 3.0 sheet lists 85 / 60 / 40 W for speeds 3 / 2 / 1, while the European sheet used above lists 73 / 65 / 42 W. Do not treat these as interchangeable versions; confirm the supplied motor nameplate and its matching performance data.
Confirm the required flow, head, liquid conditions and electrical supply with Krächtig before ordering. Price and availability on enquiry.
