Published speed ratings — LRP40-80F/250
| Speed | Electrical power (W) | Maximum flow (L/min) | Maximum head (m) |
|---|---|---|---|
| 3 | 270 | 170 | 7.3 |
| 2 | 245 | 113 | 6.7 |
| 1 | 160 | 65 | 5.4 |
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.

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.
Other LEO publications can give different maximum-flow/head figures for the same base model code. Confirm the nameplate and applicable technical sheet for the supplied unit.
Confirm the required flow, head, liquid conditions and electrical supply with Krächtig before ordering. Price and availability on enquiry.
