Spare parts for Unger HydroPower pure water equipment

In this category you will find original Unger spare parts for HydroPower pure water equipment, intended for the maintenance, repair and replacement of components in DI filters, Nano systems and RO reverse osmosis equipment.

The different HydroPower systems use specific components depending on the model and generation, so it is important to always check the equipment reference before selecting a spare part.

Spare parts for HydroPower Ultra

The HydroPower Ultra S, L and LC filters have various replaceable parts, such as covers, connectors, valves, transport components and water circuit components.

The Ultra models use the FastLock system and specific Ultra resin packs. The Ultra S uses one 6-litre pack, while the Ultra L and LC models use three 6-litre packs.

Spare parts for HydroPower RO

The reverse osmosis systems HydroPower RO S and RO M include pre-filters, membranes, a pump, inlet and outlet connections, sensors and other components that may require maintenance or replacement.

Each model uses specific parts. A connection, cartridge or component from an RO S should not automatically be considered compatible with an RO M or other RO systems.

Spare parts for HydroPower Nano

The HydroPower Nano system combines different filtration stages and also has specific components and consumables.

Before replacing any part, check the system reference and the function of the component within the water circuit.

Covers, valves and connections

Available spare parts may include covers, water inlet valves, flow regulators, hose connections and other hydraulic components.

These parts must be selected according to the exact equipment model, as there may be design and connection differences between different generations.

Trolleys and transport components

Parts related to the transport and support of certain HydroPower systems are also available, such as trolleys, wheels and structural components.

On some models, these accessories make it easier to move the filter without altering the operation of the pure water production system.

Identify the spare part before buying

To locate the correct part, always check:

  • Equipment model: HydroPower Ultra S, L, LC, Nano, RO S, RO M or another model.
  • Equipment reference: where available on the label or in the documentation.
  • Part function: water inlet, outlet, filtration, regulation, transport or structure.
  • Equipment generation: some spare parts have changed between versions.

If you have a faulty system or do not know which spare part corresponds to your model, you can call us on 627 588 844 and we will help you identify the correct part.
