Overview

This document provides technical specifications, performance data, and dimensional details for a range of bronze electric pumps (ELETTROPOMPE IN BRONZO / BRONZE ELECTRIC PUMPS). It covers various models including EPH, EP, MF (single phase), TF (three phase), and CC (direct current) types.

1. Pump Models and Types

• Models: EP 20, EP 25, EP 30, EP 40, EP 50, EP 70, EPH 20, EPH 25, and variants with suffixes MF (single phase), TF (three phase), CC (direct current).
• Power Ratings: Range from 0.3 kW to 7.5 kW.
• Motor Types: Single phase (MF), three phase (TF), direct current (CC).
• Additional Features: Some pumps include handles, terminal board connections, and on-off reverse switches with capacitor boxes.

2. Performance Parameters

• Flow Rate (Q): Expressed in gallons per minute (Gal. USA/min) and liters per minute (l/min), with values ranging from 5 to 125 l/min or higher depending on model.
• Head (H): Measured in meters (m) or feet (ft), indicating the pump's pressure capability, with values up to approximately 120 m.
• Speed (RPM): Motor speeds typically at 1400 or 2800 rpm, with some models at 3000 rpm.
• Voltage and Current: Motors operate at voltages such as 12V, 24V, 230V, and 230-400V, with corresponding current ratings provided.

3. Technical Specifications and Weights

• Weights vary by model, from approximately 5.5 kg to 87 kg.
• Power ratings in horsepower (HP) and kilowatts (kW) are specified for each model.
• Some models have detailed electrical characteristics including voltage, current, and motor type.

4. Pipe Fittings and Dimensions

• Pipe fittings are specified with BSP thread sizes ranging from 3/4" to 2 1/2" for inlet and outlet connections.
• Dimensions for each pump model are provided in millimeters, including length, width, height, and specific fitting sizes.
• Some fittings or connections are marked as not available (n.d.) or available on request (X).

5. Installation and Protection

• Protection class IP55 is indicated for motors, ensuring dust and water resistance.
• Terminal board connections and handle inclusion are noted for ease of installation and handling.

6. Notes and Legend

• MF = Monofase (Single Phase)
• TF = Trifase (Three Phase)
• CC = Corrente Continua (Direct Current)
• M = Motor with on-off reverse switch and capacitor box
• M2 = Motor with terminal board connection
• n.d. = Not available
• X = Available on request

Summary

This document serves as a comprehensive technical reference for selecting and installing bronze electric pumps across various power ratings and motor types. It includes detailed performance curves, electrical data, mechanical dimensions, and connection specifications to support engineering and procurement decisions.
