BMA-G 40/140 230/400V 3Ph Gianneschi Pump – self-priming electric pump for grey and loaded water

The BMA-G 40/140 pump from Gianneschi Pumps and Blowers belongs to the series of BMA-G self-priming electric pumps designed for the handling of grey water and slightly loaded fluids with small suspended solids.

The model is configured with three-phase 230/400V 3~ power supply, 2.2 kW power, and an integrated anti-clogging system with open impeller, a construction solution suitable for technical and nautical systems where service continuity and fluid management are fundamental aspects.

The BMA-G series derives from the development of Gianneschi double volute self-priming centrifugal pumps and is specifically designed for applications of draining loaded water and grey water.

Main features

Double volute self-priming construction

The BMA-G 40/140 is a double volute self-priming centrifugal electric pump with open impeller and integrated anti-clogging system. This configuration is suitable for handling fluids with the presence of small suspended solids.

Anti-clogging system

The BMA-G series is designed to reduce the risk of clogging during operation with slightly loaded or grey water, thanks to the combination of:

• onboard technical services
• technical rooms and plant compartments
• handling of slightly loaded fluids with small suspended solids

In the nautical field, it can be used in systems dedicated to the management of grey and wastewater, compatible with the system sizing.

Operational advantages

Facilitated integration

The availability of threaded or flanged connections allows greater flexibility during installation, replacement, or refitting of the system.

Handling of fluids with impurities

The combination of open impeller and anti-clogging system is designed for applications where the fluid may contain residues or small suspended bodies.

Technical components

The use of bronze and stainless steel in the main components helps maintain robustness and operational continuity in professional and marine applications.

Recommended installation and checks

Before installation, it is advisable to check:

• compatibility of the power line with 230/400V three-phase supply
• correct sizing of the piping
• head and flow rate required by the system
• type of necessary connection
• characteristics of the fluid to be moved

For continuous applications or complex systems, it is advisable to refer to the complete technical documentation and the manufacturer's performance curve.
