Sanisplit NK3 24 V DC – code: T-PF.SPLIT/NK24V – Tecma

Sanisplit NK3 24 V DC Tecma (code T-PF.SPLIT/NK24V)

The Sanisplit NK3 24 V DC by Tecma (Thetford Marine) is a lifting station for discharge systems in nautical environments, designed for the management of wastewater on board. The peculiarity of the system is the architecture “Split” (in two separable parts), designed to simplify installation and maintenance compared to traditional solutions.

It is suitable when you want to build or upgrade an onboard bathroom in locations not always convenient relative to the main drain line, for example in areas far from the pipe or in system configurations that require a dedicated lifting system.

Main features and details

“Split” system (modular and separable)

The distinctive feature of the Sanisplit NK3 is the Split: the section that integrates engine and grinder can be separated from the body with check valve via a lever. This approach is designed to make control and maintenance operations easier, reducing the need for invasive interventions on the system.

Type and intended use

The Sanisplit NK3 is described as maceration lifting station for applications on:

• Black water (WC)
• Grey water (shower, bidet, sink)

The configuration is designed to support a complete bathroom and to integrate into systems where waste management requires a dedicated unit.

Typical applications in the nautical field

• Installations or refit of WC and services in areas far from the main pipe.
• Centralized management of waste from a complete bathroom (Toilet + grey water such as shower/sink/bidet).
• Systems where a solution designed to facilitate inspection and maintenance of the pumping part is desired.

Operational advantages

More accessible maintenance (modular approach)

Compared to traditional systems that may require disassembling the toilet and pipes in case of blockage or intervention, the structure Split is designed to allow separation of the motor/grinder part from the valve body without disconnecting the pipes. This can result in faster interventions with less operational complexity.

Management of black and grey water

The possibility to use the system for both black water and for grey water makes it suitable for configurations where multiple bathroom fixtures converge into the same drainage logic, simplifying system design during installation or refit.

Dedicated solution for 24 V DC systems

The power supply 24 V DC is consistent with many onboard configurations based on battery banks. This makes the product relevant for those working on typical electrical and hydraulic systems in the nautical sector.

Usage and important notes

General installation and management guidelines

For a reliable long-term result, it is advisable that installation be carried out following the manufacturer's instructions and with particular attention to:

• correct sizing and laying of drain pipes;
• accessibility of the unit for any checks;
• electrical protection consistent with the value 30A fuse specified range;
• verification of the compatibility of the onboard system with the power supply 24 V DC.

Note on compatibility

In the available data the system is indicated as ideal for marine toilets with direct discharge or with integrated grinder. In case of doubts about the configuration of your toilet or the system layout (connected fixtures, pipe routes, levels and distances), it is advisable to check the intended installation diagram and the Tecma documentation associated with the code T-PF.SPLIT/NK24V.
