CM-1
PDF datasheet mirror for CM-1 (Grundfos Pumps). Verify with OEM before design.
Summary
Product identification
The GRUNDFOS CR 15, CRI 15, CRN 15, CRE 15, CRIE 15, and CRNE 15 series are Vertical Multistage Centrifugal Pumps designed for 50 Hz operation.
Operating limits
Performance curves for the CR, CRI, CRN, CRE, CRIE, and CRNE series are provided, showing flow rates (Q) in m³/h and l/s, head (H) in m, pressure (p) in kPa, power (P₂) in kW, efficiency (Eta) in %, and Net Positive Suction Head (NPSH) in m. These curves are based on 2900 rpm and conform to ISO 9906 Annex A.
See the official PDF for detailed performance and NPSH curves.
Electrical
The pumps operate at 50 Hz.
- CR, CRI, CRN series: 3 x 380-415 V.
- CRE, CRIE, CRNE series: Equipped with a single-phase motor (1x220-240 V).
