Product Identification

The pump identification code follows this structure: ME [Nominal Power in HP] [Version] [Nominal Ø Suction Port] - [Nominal Capacity in m³/h] / [Number of Stages]

• ME: Monobloc electric pump
• Nominal Power in HP: e.g., 50
• Version:
  • K: Horizontal version
  • KV: Vertical version
• Nominal Ø Suction Port: e.g., 65 (DN 65)
• Nominal Capacity in m³/h: e.g., 42
• Number of Stages: e.g., 4

Example: ME50K65-42/4 indicates a monobloc electric pump with a 50 HP motor, horizontal version, DN 65 nominal suction port, 42 m³/h nominal capacity, and 4 stages.

Operating Limits

• Max. solids contents: 50 g/m³
• Max. water temperature: 90°C
• Max. running time with Q=0: 2 min
