Overview: The document describes high-pressure liquid-ring centrifugal self-priming electric pumps made of bronze, specifically designed for the nautical sector. These pumps are used for various applications such as emptying bilges, supplying anti-fire equipment, washing chains, and transferring diesel oil.

Specifications: The pumps are available in different models, including BAHP 80, BAHP 90, and BAHP 91. They operate on both single-phase (1ph) and three-phase (3ph) power supplies with voltage options of 230V and 400V. The nominal motor power (P2) ranges from 0.12 kW to 2.4 kW, depending on the model.

Performance Parameters: The pumps have varying flow rates (Q) measured in cubic meters per hour (m3/h) and liters per minute (L/min), with head (H) measured in meters (m). For instance, the BAHP 80 model has a flow rate of 1.3 m3/h and a head of 3.6 meters.

Dimensions and Connections: The document provides detailed dimensions and connection specifications for each pump model, including diameter (DN), height (h), and weight (kg). The pumps have threaded connections (G1, G3/4) for easy installation.

Applications: These pumps are particularly suitable for nautical applications due to their self-priming capability and high-pressure performance, making them ideal for emergency and maintenance tasks on boats and ships.
