RX, RADIAL IMPELLER

Product catalog summary

Overview

This document details the RX series 8-inch radial electric submersible pumps by Panelli, designed for high head, small to medium flow rate applications. Constructed entirely from stainless steel (AISI 304), these pumps offer durability and corrosion resistance.

1. Product Description and Design Features

Radial impeller pumps with compact axial stage dimensions (impeller, diffuser, casing).
Multi-stage capability allows achieving high heads within the same well diameter.
Standard full stainless steel construction including suction cage, delivery bowl, non-return valve, impeller, rods, and diffuser.

2. Materials

Major components made from AISI 304 stainless steel for corrosion resistance and strength.
Use of rubber bearing bushes and spacers for wear resistance and sealing.
Microfusion casting employed for certain components to enhance precision and durability.

3. Performance Specifications

Flow capacity: 300 to 1300 liters per minute depending on model.
Manometric head: 32 to 700 meters, varying by pump type and number of stages.
Power ratings up to 100 HP (75 kW).
Maximum efficiency approximately 75%.
Maximum sand content tolerated: 50 g/m³ to prevent damage.
Minimum submergence required: 1 meter to avoid cavitation.

4. Standards and Tolerances

Manufactured in compliance with EN UNI-ISO 9906 standards ensuring pump performance and tolerance reliability.

5. Construction Details and Components

Comprehensive list of components including suction cage, strainer, delivery bowl, valve body, impeller, shaft, tension rods, spacers, nuts, bolts, and rubber bushes.
All metallic parts are AISI 304 stainless steel, ensuring corrosion resistance and mechanical strength.

6. Performance Curves and Data

Graphs and tables illustrate relationships between flow rate (Q), head (H), power consumption (kW), and efficiency (%).
Performance data covers different RX 8” pump variants such as 180 RX27, RX36, and RX50.
Power absorption per stage ranges from 2.00 kW to 3.95 kW depending on model and operating conditions.

7. Dimensions and Weights

Overall dimensions (A, B, C in mm) and weights (kg) provided for various pump types.
Weight varies from approximately 42 kg to over 168 kg depending on model and power rating.

Critical Information and Recommendations

Suitable for high head, moderate flow rate applications.
Maximum sand content in pumped fluid should not exceed 50 g/m³ to avoid damage.
Minimum submergence of 1 meter is essential to prevent cavitation and ensure proper operation.
Monitor operating power and efficiency to optimize performance and energy consumption.
Compliance with EN UNI-ISO 9906 guarantees reliability and quality.

Summary

The RX series 8” stainless steel radial submersible pumps by Panelli are engineered for demanding industrial and water supply applications requiring high head and moderate flow. Their robust stainless steel construction, adherence to international standards, and detailed performance data support reliable, efficient, and durable operation. The document provides comprehensive technical specifications, material descriptions, performance curves, and dimensional data to assist in pump selection and application.
