24 V discharge pump – code: 50890-1100 (0325089024) – Jabsco

Jabsco 24 V discharge pump 50890-1100 (0325089024)

The Jabsco discharge pump with power supply 24 V, original reference 50890-1100 and Jabsco Italy code 0325089024, is a solution designed for managing onboard discharges in the nautical field. It is a diaphragm pump designed to offer flexible installation thanks to the adjustable head and has a compact size, making it suitable for both new installations and replacement/maintenance work on existing systems.

Suitable for applications such as sink drains, shower and black water, it is described as a pump with quiet with minimal vibrations and with protected mechanical parts for better operational safety. The configuration is without pre-filteran aspect to consider during system design and routine maintenance.

Design oriented towards installation

One of the strengths of the series is the adjustable head, indicated as 360° swivel and with a multiple positions, useful for adapting the orientation of the fittings to the needs of the technical compartment and the routing of the pipes. The 38 mm hose connectors at inlet/outlet simplify integration with appropriately sized drain lines, typical of onboard systems for grey and black water.

Operation and management

The pump is described as very quiet and with minimal vibrations, features appreciated in a nautical environment, especially when installed near cabins or living areas. The possibility of dry running, is also indicated, useful in some operating conditions (for example during emptying or priming), provided the limits of continuous use up to 30 minutes.

The configuration without pre-filter makes it important to assess the quality of the fluid to be moved and the possible presence of foreign bodies: in systems where this is possible, it may be appropriate to provide adequate upstream management according to the installation requirements.

Typical onboard applications

This pump is suitable for various uses related to nautical drainage, including:

• Sink drains (grey water)
• Shower drains (grey water)
• Black water management and systems connected to black water tanks (as described)

Thanks to the mounting flexibility and 38 mm connections, it is suitable in contexts where a compact and easily integrable solution into the system layout is desired.

Operational advantages

• Flexible installation: 360° swivel head/multiple positions to orient fittings based on available space.
• Compact size: simple and compact design, useful in onboard technical compartments.
• Onboard comfort: operation indicated as quiet and with minimal vibrations.
• Practical management: self-priming up to 3 m and possibility of dry running (according to description).
• Safety: protected mechanical parts (as reported in existing content).

Usage and installation notes

Electrical indications (24 V)

For the 24 V (50890-1100 / 0325089024) are reported max consumption 2.5 A and 5 A fuse. During installation it is good practice to verify the correct circuit protection and the compatibility of the onboard system with the indicated consumption, as well as to ensure electrical connections suitable for the marine environment.

Hydraulic indications

Connections are provided with 38 mm hose connectors at input/output. To achieve regular operation, it is advisable to take care of the piping route (bends, restrictions, uphill sections) and consider the declared data of maximum head 4 m and self-priming up to 3 m in relation to the actual system configuration.

Continuous use and operating conditions

An operation in continuous use up to 30 minutes. For applications requiring prolonged cycles, it is appropriate to plan usage respecting this indication. The possibility of dry running is an operational advantage, but does not replace proper system management and maintenance.

Note on 12 V / 24 V variants

The series is indicated as also available in 12 V; version; this datasheet refers to the 24 V variant identified by the codes 50890-1100 and 0325089024. In case of replacement, always check the code and the power supply present onboard.
