Par-max 3 autoclave – 12v – code: 3103139513 – Jabsco

Jabsco PAR-MAX 3 12V autoclave (code 3103139513)

The’PAR-MAX 3 autoclave by Jabsco is a pressurized water pump designed for water systems where compact size, simple installation, and automatic pressure management are required. Thanks to the integrated pressure switch and diaphragm technology, the pump operates according to the system demand, making it suitable for typical onboard users and small systems with multiple draw-off points.

This version is at 12 V DC and is suitable for use up to three outlet points, with quick connections that facilitate installation and maintenance interventions.

Features and construction details

Operation and control

• Integrated pressure switch: automatic start/stop based on system demand.
• Diaphragm technology: typical solution for pressurized pumps, designed for smooth operation.
• Self-priming: useful during system start-up and after maintenance interventions.
• Safe for dry running: feature designed to handle possible water shortage conditions (it is still good practice to avoid prolonged dry running).

Installation and maintenance

• Quick-connect outlets: designed to make installation, maintenance, and servicing easier.
• Anti-vibration feet: useful to reduce the transmission of vibrations to the mounting structure.
• Horizontal or vertical mounting: useful flexibility when available space is limited.
• Built-in filter: helps to retain impurities, contributing to pump protection.

Protection and materials

• Waterproof according to IPX6.
• Plastic housing: designed to protect against corrosion.

Important note

Not suitable for continuous operation: the pump is designed to work on demand, with start/stop cycles managed by the pressure switch.

Typical applications

In the nautical and onboard system context, an autoclave like the PAR-MAX 3 is normally used to supply a pressurized water circuit when a more stable and automatic delivery is desired compared to manual or non-pressurized solutions.

• Onboard water systems with multiple outlets (up to three indicated exit points).
• Taps and shower heads in systems where automatic pressurization is required.
• Small service circuits where reduced size and flexible installation (horizontal/vertical) matter.

Note: the maximum flow rate may vary depending on system conditions (e.g., voltage drops, pipe diameter, and other installation variables).

Advantages for the installer and the user

Automatic management and convenience

The integrated pressure switch allows the pump to activate when water is requested and to stop when the request ends. This approach is particularly useful in systems with multiple users, as it simplifies daily management and reduces the need for manual interventions.

Neater installation

The quick-connect fittings and the possibility of mounting in multiple orientations help optimize technical spaces. The overall dimensions and the distance between fixing holes (reported in the specifications) support prior verification during replacement or new installation.

Protection and operational reliability

The presence of integrated filter shape and the’plastic housing designed for corrosion protection are useful elements in environments where humidity and splashes may be frequent. The classification IPX6 adds an additional level of protection under conditions compatible with that rating.

Usage and operational notes

System guidelines

• Check the compatibility of the power supply at 12 V DC and properly size the electrical line.
• Use an fuse inline as indicated: 10.0 A.
• Respect the’liquid temperature range indicated: 0 – 60 °C.
• Check the connections (2x 1/2" / 13 mm) and the correct sealing of the connections.

Good practices

• Although indicated as safe for dry running operation, It is advisable to avoid prolonged water shortage conditions.
• Do not use the pump in continuous operation; it is designed to operate on demand.
• Periodically inspect the integrated filter and keep it clean to reduce the risk of performance drops due to impurities.
