Overview of EP Series Coaxial Pumps

The document provides detailed technical specifications and performance data for the EP series of coaxial pumps, including models EP MINI 3/4", EP MIDEX 1"1/4, EP MINOR 40, EP MAJOR 60, and EP MAXI 80.

1. Pump Types and Motor Options

• Types: EP MINI, EP MIDEX, EP MINOR, EP MAJOR, EP MAXI
• Motor types available: Single-phase (MF), Three-phase (TF), Direct Current (CC)
• Speeds range from 470 to 1400 RPM depending on model and motor type

2. Performance Specifications

• Flow rates vary widely, from approximately 400 to 40,000 liters per hour (l/h) or 1200 to 9000 US gallons per hour (Gal USA/h), depending on pump size and speed.
• Head (prevalence) ranges from 4 to 60 meters, with corresponding flow rates at different heads provided.
• Speed options include multiple RPM settings for each pump type, allowing for performance tuning.

3. Motor Power and Electrical Characteristics

• Power ratings range from 0.3 kW to 3.5 kW depending on pump and motor type.
• Voltage options include 12V and 24V DC, as well as single-phase and three-phase AC motors.
• Current ratings and motor speeds are specified for each configuration.

4. Dimensions and Weight

• Dimensions are provided in millimeters for each pump type, including key measurements such as length, width, height, and mounting positions.
• Weights range from approximately 9-10 kg for smaller models (EP MINI) up to 68 kg for larger models (EP MINOR).

5. Installation and Connection Details

• Available pipe fittings and connection types are referenced (details on page 21).
• Motor connection options include terminal board (I1) and on-off/reverse switch (I2).
• Positions for motor and pump connections are specified with dimensional references.

6. Operational Limits and Recommendations

• Maximum RPM limits are indicated for each pump model to ensure safe operation (e.g., MAXI-600 RPM, MAJOR-900 RPM).
• Performance curves suggest optimal operating ranges for flow and head to maximize efficiency and pump life.

Summary Table Highlights

• Flow capacities at various heads and speeds for each pump model.
