CRI CCB 04-25C — 50 Hz Three-Speed Circulation Pump
CRI CCB 04-25C 50 Hz three-speed catalogue reference with native High, Medium and Low curves, separate speed-specific table limits and qualified dimensional references. Supplied configuration requires confirmation.
CRI CCB 04-25C circulation pump
Three-speed circulation pump catalogue reference within the existing CRI CP range.
This page describes the exact CCB 04-25C three-speed catalogue reference. High, Medium and Low remain separate manufacturer speed references. The selected commercial supply, motor, controls and connection arrangement require confirmation.

| Inlet / outlet reference | 1½ inches |
| Catalogue weight reference | 2.4 kg |
Speed-specific manufacturer table limits
| Speed | Power (W) | Current (A) | Maximum head (m) — separate limit | Maximum flow (m³/h) — separate limit |
|---|---|---|---|---|
| H — High | 72 | 0.33 | 4.5 | 2.9 |
| M — Medium | 53 | 0.24 | 4 | 2.2 |
| L — Low | 38 | 0.17 | 3 | 1.1 |
Model-specific hydraulic curves
Maximum head and maximum flow are separate table limits for each speed; they do not describe one operating duty. The native head traces are reproduced as drawn, independently of the tabulated maxima. No efficiency trace, tabulated duty points, zero-head flow or extrapolated performance is inferred. Confirm the selected duty with the manufacturer. The manufacturer prints a common head-curve panel above the separate CCB 04-25A and CCB 04-25C rows; that shared panel is used for this exact named model, while its dimensional row remains distinct.
Model-specific dimensional references
| Reference | Manufacturer value |
|---|---|
| Height H | 180 mm |
| Connection size DN | 25 |
| First printed L (mm) column | 129 mm |
| D reference | 1½ inches |
| Second printed L (mm) column | 123 mm |
The manufacturer dimensional table prints two separate columns headed L (mm). Their literal values are retained as first and second L references. The drawing labels D1 separately; neither L value is reassigned to D1. Confirm the final dimension-to-drawing mapping and supplied assembly drawing before installation.
The exact performance row specifies a 180 mm port-to-port reference, agreeing with H = 180 mm in the dimensional row. The 1½ inches inlet/outlet reference does not establish flange drilling or pressure class. No flange-type asterisk is printed for this exact model.
Power and current are speed-specific catalogue references: H 72 W / 0.33 A, M 53 W / 0.24 A, L 38 W / 0.17 A. These do not identify a selected supplied motor, voltage or control package. The 2.5 µF capacitor and 2.4 kg catalogue weight are not a supplied accessory or packed/shipping-weight claim.
Permissible working pressure, temperature, materials and selected installation require confirmation for quotation. No model-specific working-pressure rating or supplied accessory package is assigned here.
