MEK/MEKV/MEKDV series 50Hz

Summary

Product identification

The Rovatti Pumps MEK/MEKV/MEKDV series consists of close-coupled monobloc multistage electric pumps. These pumps are designed for water supply and boosting in irrigation, residential, and industrial applications. They are characterized by efficiency, low noise, reduced overall dimensions, and advanced technical solutions for reliable pumping of a wide variety of liquids, offering a broad performance range and easy maintenance.

The product identification code follows a structure such as ME50K65-42/6-TB:

• ME: Monobloc electric pump
• 50: Nominal power in HP (range 10 ÷ 220 HP)
• K: Horizontal version (KV for Vertical, KDV for Vertical)
• 65: Nominal Ø suction port (available DN 65, 80, 100, 150)
• 42: Nominal capacity in m³/h (range 22 ÷ 200 m³/h)
• 6: Number of stages (range 1 ÷ 9 stages)
• -TB: Seal type (e.g., Gland packing version)
