Gulper 220 12 V – code: 16.155.20 – Osculati

Gulper 220 12 V Osculati diaphragm pump (code 16.155.20)

The Gulper 220 12 V Osculati (supplier code 16.155.20) is a diaphragm pump designed for pumping waste water in nautical and onboard plant applications. The construction with large single diaphragm and valves without restrictions It is designed to handle fluids with the presence of air, maintaining regular operation and suitable for installations where reliability and ease of maintenance are required.

Among the distinctive features: quiet operation, ability to operate without filter (as indicated by the manufacturer), self-priming up to 3 m and capacity of run dry. Installation is facilitated by the configuration designed for tight spaces and by the 360° rotatable outlets, useful for optimizing pipe routing.

• Can pump air and water mixtures.
• Easy to install in tight spaces.
• Low consumption (manufacturer's description; refer to the indicated absorption values).

Typical onboard applications

The Gulper 220 is suitable for systems where it is necessary to move wastewater and where the presence of air in the circuit can be frequent. It is a solution suitable for various onboard configurations, especially when a pump is desired:

• usable in drainage systems and wastewater transfer;
• installable in technical compartments or areas with limited access;
• with adjustable connections to simplify pipe installation;
• capable of handling operating conditions that are not always “perfect”, such as air in the circuit or intermittent operation.

Advantages for installation and maintenance

More flexible mounting

I 360° rotatable outlets helps reduce orientation constraints, making it easier to align with existing pipes and optimize space. This aspect is particularly useful when working in tight spaces or when mandatory paths must be followed.

Flow management and continuity

The presence of the double outlet valve is designed to promote a continuous flow. In real applications, this can result in smoother behavior during pumping, especially in systems where the required flow rate may vary.

Practical operation

The pump is rated self-priming up to 3 m and can run dry. Additionally, the ability to pump air and water mixtures makes it suitable for situations where the suction is not always completely “full”.

Low noise level

The manufacturer indicates a quiet operation, a feature appreciated in onboard installations where comfort and reduction of perceived vibrations are important.

Usage and operational notes

Guidelines for proper integration into the system

• Voltage check: ensure that the system is at 12 V.
• Pipe sizing: use fittings and pipes compatible with 19 mm hose holder.
• Placement: evaluate the installation point based on aspiration and head requirements, respecting the declared maximum values (3 m).
• Air management: the pump is suitable for air/water mixtures; it is still good practice to reduce, when possible, unwanted air ingress to stabilize the circuit.

Note on filter and maintenance

The manufacturer's description indicates that no filter is needed. During design or refitting, it is still advisable to assess the overall condition of the system (pipes, fittings, any foreign bodies) to maintain regular operation over time and reduce unplanned interventions.
