4 membrane bilge pump 24V 17 L – code: 16.525.24 – Osculati

4 membrane bilge pump 24V 17 L Osculati (code 16.525.24)

The 4 membrane bilge pump Osculati 24V (code 16.525.24) is a solution designed for onboard systems where reliability and ease of installation and maintenance are required. It is indicated as a bilge pump and, thanks to its membrane configuration, can also be used in service applications such as grey water discharge from collection sumps or as a water loading pump for Silent toilets, according to the plant setup specifications.

The pump body is designed to run dry without damage, a useful feature in typical bilge or technical compartment conditions. It also integrates a reverse polarity protection and adopts internal stainless steel bearings, elements that contribute to safer management suitable for the marine environment.

Features and construction details

Membrane and valve configuration

This pump is a 4 diaphragm with 4 valves. Membrane technology is often chosen onboard when a versatile service pump suitable for various circuits is desired, with smooth operation and good handling of liquids compatible with the system.

Power supply and protections

• Power Supply: 24V.
• Reverse polarity protection: integrated, useful during connection and maintenance phases.
• Dry operation: can run dry without damage (as per product specification).

Internal components

• Internal stainless steel bearings.

Fittings and filter included (snap fitting)

To simplify installation, the pump is supplied complete with fittings and suction filter, with snap fitting:

• 4 fittings included:
• 2 fittings of 1/2″ threaded
• 1 fitting straight hose outlet from 14 mm
• 1 fitting 90° hose outlet from 14 mm
• Suction filter included.

Available data (installation and dimensions)

• Indicated capacity: 17 L.
• Mounting height: up to m 1.80 above level.
• Dimensions (mm): 240x105x95.
• Consumption (A): 5,6 (value reported in product data).
• Weight: 2.8 (as per available data).
• Replacement filter: 16.533.01.

Recommended onboard applications

In the nautical and onboard plant field, this pump can be used in various contexts, depending on the system configuration and fluid management needs:

• Bilge pump for management and transfer of liquids present in technical compartments.
• Grey water discharge from collection bilges, where provided by the system.
• Water loading pump for Silent toilets, as a dedicated service component.

The supply of fittings (threaded and hose fittings, including the 90° elbow) helps adapt the connection to the typical geometries of onboard compartments, reducing the need for additional components during assembly.

Operational advantages

Greater tolerance to operating conditions

The ability to run dry without damage is a practical advantage in situations where suction may not be continuous or when the liquid level changes rapidly. This aspect is particularly useful in bilge and drainage circuits.

Faster and tidier installation

The supply complete with fittings and intake filter, with snap fitting, allows for a more straightforward installation and easier management of routine maintenance interventions (filter cleaning, connection checks, replacements).

Safety in electrical connection

The reverse polarity protection adds a level of protection during wiring, replacements, or interventions in confined spaces, where connection errors can occur more easily.

Components suitable for the onboard environment

I internal stainless steel bearings they represent a relevant construction detail for use in a nautical environment, where humidity and operating conditions require suitable materials.

Usage and installation notes

Positioning and mounting height

The product shows a’mounting height up to m 1.80 above level. During installation, it is good practice to check the routing of the pipes, the presence of bends and restrictions, and the accessibility of the suction filter for maintenance.

Choice of fittings and connections

The pump is supplied with fittings 1/2″ threaded and 14 mm hose connectors (straight and 90°). The choice of the most suitable fitting depends on the existing line and available space. The snap-in connection facilitates assembly/disassembly operations, useful when periodic maintenance is expected.

Suction filter and spare parts

The intake filter included helps to retain impurities and debris. For spare parts management, the replacement filter 16.533.01. is recommended. In contexts with residue presence, it is advisable to check and clean the filter regularly, compatible with the use of the boat and operating conditions.

Note on consumption

The available data shows a consumption of 5.6 A. When integrating into the onboard electrical system, verify the correct circuit protection and cable section according to the onboard wiring rules adopted.
