Performance and Materials
The document includes performance curves and tables for various models, detailing flow rates, head, power consumption, and efficiency. It highlights the use of stainless steel and other durable materials like Teflon and nitrile rubber for critical parts.

Applications
The pumps are designed for high-volume water needs, suitable for:

Deep well water extraction.
Irrigation and water distribution systems.
Water treatment and reverse osmosis systems.
Industrial cooling processes.
Decorative fountains and fire-fighting systems.

Performance Curves and Symbols Explanation
The document provides performance curves for pumps, explaining key symbols: Q for volume flow rate, H for total head, P2 for pump input power (shaft power), and η for pump efficiency. Tolerances comply with ISO 9906 Annex A.

Performance Tables at ~2900 rpm
Performance tables are included for pumps operating at approximately 2900 rpm, detailing dimensions and specifications for different pump models, including motor adapters for 6” and 8” motors.

Dimensions and Motor Adapters
Dimensions are provided for pumps with different motor configurations. For an 8” pump, dimensions are 186.5 mm with one cable cover and 192 mm with two cable covers. With a 6” motor, the external motor diameter is 136.5 mm, and with an 8” motor, it is 187.5 mm.

Pump Models and Specifications
The document lists various pump models, specifying motor size, power in kW and HP, dimensions in mm, and weight in kg. For example, the 86 BHE 77 - 2 model with a 6” motor has a power of 7.5 kW (10 HP), dimensions of 644 mm, and weighs 31.5 kg. Specifications vary across models, with power ranging from 7.5 kW to 110 kW and weights from 31.5 kg to 136 kg.
