Explosion Proof Pump Groups Without Electrical Control Panels

This document provides technical specifications and details for explosion-proof pump groups designed without integrated electrical control panels. These pumps are suitable for hazardous environments requiring explosion-proof equipment.

1. Product Types and Models

• GR ADPE NAUTIC Series: Available in sizes 30, 40, 50, and 70 with bronze impellers; also a 70 Inox (stainless steel) variant.
• GR ADPE SPECIAL Series: Includes models 30, 40, 50, and specialized versions named MASTER (2") and SENIOR (1"1/2).

2. Performance Parameters

• Flow Capacity (Q): Ranges from approximately 6 to 500 US gallons per minute (Gal. USA/min) or equivalent in liters per minute (l/min).
• Head (H): Expressed in meters (m) or feet (ft), indicating the pump's pressure capability.
• Speed (Rpm): Standard operating speed is 1400 rpm for all models.

3. Motor Specifications

• Voltage: 230-400 V
• Phase: Three-phase (TF)
• Power Range: From 0.75 kW (approximately 1 HP) up to 7.5 kW (approximately 10 HP) depending on model.

4. Materials and Construction

• Impellers are primarily bronze; stainless steel (Inox) impellers available for specific models.
• Pipe fittings can be stainless steel or nylon upon request; some fittings are not available for certain models.

5. Dimensions and Weight

• Dimensions vary by model, with detailed measurements provided for length, width, height, and inlet/outlet sizes.
• Weights range from approximately 39.5 kg to 125 kg depending on model and construction.

6. Inlet and Outlet Connections

• Standard connections use BSP (Gas) threads; other connection types are available on request.
• Sizes include BSP-M 1"1/4, 1"1/2, 2", and BSP-F 2"1/2 depending on model.

7. Additional Notes and Recommendations

• Models are available both on base and on trolley configurations.
• Explosion-proof certification implies suitability for hazardous environments without integrated electrical control panels.
• Users should specify desired pipe fittings and connection types when ordering.
