Marco 12 V 35 l/m self-priming bilge pump – code: 16.165.12 – Osculati

Self-priming bilge pump Marco 12 V 35 l/min (code 16.165.12) – Osculati

The self-priming bilge pump Marco is a solution designed for onboard applications where construction reliability and neat installation are required. This model with 12 V with maximum flow rate 35 l/min (supplier code 16.165.12) belongs to the series with rubber impeller and incorporates useful features in the nautical field, such as internal EMI noise filter, waterproof body and watertight cable gland. The presence of the integrated flange (“New Integrated Flange”) contributes to a cleaner and more functional installation inside the technical compartment.

Features and construction details

Series with rubber impeller

The pump uses a rubber impeller, a common solution in self-priming pumps to achieve good suction capacity and smooth operation. The impeller is a wear component: for this reason, a dedicated impeller replacement is provided.

Construction and integrated protections

• High-quality construction, suitable for technical uses in the nautical environment.
• Internal EMI noise filter, useful to reduce electromagnetic interference on the onboard electrical system.
• Waterproof body and watertight cable gland, for greater protection in installations in areas exposed to humidity and splashes.
• New Integrated Flange: integrated flange for practical fastening and a neater installation.

Declared compliance

The product is indicated as compliant with ISO 8849/8846

Typical onboard applications

This self-priming bilge pump is designed for use in systems where a compact pump is useful, with hose connection and 12 V power supply. In the nautical field, it can be used in various contexts of liquid management and handling, depending on the system configuration and onboard needs.

• Bilge: supports bilge water drainage and management operations, in installations where a self-priming pump is required.
• Liquid transfer: handling in technical circuits compatible with rubber impeller pumps, paying attention to the correct choice of materials and maintenance.
• Maintenance and services: use in onboard operations where an electric pump with stable installation and protected wiring is needed.

For the correct choice, it is good practice to check compatibility with your system (pipes, connections, power supply, and installation conditions) and follow the manufacturer's instructions.

Advantages for installation and management

Cleaner installation with integrated flange

The integrated flange facilitates fastening and helps maintain a tidy layout in the technical compartment. This aspect is is especially useful when space is limited or when an easily inspectable installation is desired.

Reduction of electrical disturbances

The internal EMI noise filter is an important detail in the nautical environment, where multiple users share the same electrical network. It contributes to a “cleaner” management in terms of interference, especially in the presence of instrumentation and electronic devices.

Protection in humid environments

The waterproof body and the watertight cable gland are designed to withstand typical onboard conditions. Adequate protection of electrical components and cable passages helps keep the system more reliable over time, if installed correctly.

Programmable maintenance

The presence of impeller spare code 16.193.73 allows planning maintenance and performance restoration over time. In impeller pumps, periodic replacement of the impeller is a common intervention, especially in case of frequent use or harsh conditions.

Usage and operational notes

General installation guidelines

• Alimentazione: prepare an adequate 12 V line and electrical protections consistent with the onboard system.
• Hydraulic connections: use pipes compatible with 1/2" hose holder and ensure proper tightening to avoid leaks.
• Placement: install in an accessible point for inspection and maintenance, minimizing curves and restrictions in the circuit as much as possible.
• Priming height: the pump is self-priming up to 1.5 m; when designing the system, consider the suction height and pressure losses.

Notes on use and compatibility

For correct use, follow the manufacturer's instructions and good nautical system practices. The choice of the liquid to be moved and the system materials must be consistent with a rubber impeller pump and the installation environment.
