  • Knives

    Mono-blade knives or multi-knife discs efficiently fragment effluents into fine particles using a rotating stainless steel blade, which is both durable and corrosion-resistant. This mechanical process facilitates the tearing and pumping of sewage in small-diameter pipes while minimizing the risk of blockages.

  • Grinding wheels

    Designed to handle occasional waste (wipes, tampons, etc.), the grinding wheels fragment solids without disrupting the flow of wastewater. An ideal solution for collective use, they ensure effective management of unexpected waste and prevent blockages.

  • Single-channel, double-channel, or multi-channel wheels

    Integrated into our pumping stations, they are designed with one, two, or more channels and allow the passage of liquids containing solids or fibers. They are particularly effective in preventing blockages when pumping wastewater.

  • Vortex wheel

    Equipped with vortex technology, the KX V6 wheel generates a powerful rotational flow to evacuate solids without direct contact with the blades. Designed for the most demanding applications, it ensures long-lasting performance while reducing maintenance requirements.

Single and multi grinders

Knives

The single-blade cutter cuts effluent into fine particles. The cutter's operation is based on a simple and efficient mechanical process. As effluent enters the system, the stainless steel blade, designed for durability and corrosion resistance, rotates continuously. This rotation breaks up solid matter, such as toilet paper and feces, reducing it to fine particles. At the same time, the device ensures the discharge of wastewater. Thanks to this dual action, effluent is evacuated through small-diameter pipes.

Grinding wheels

The Pro X K2 and Pro X K3 grinding wheels have been designed to handle occasional waste such as toilet wipes, sanitary pads, tampons, or condoms. These grinding wheels use advanced grinding technology to shred solid materials that may be present in effluents and are capable of processing difficult waste, such as toilet wipes, sanitary pads, tampons, or condoms, without compromising the smooth operation of the system.

Thanks to their robust design, the grinding wheels are recommended for commercial use.

Single-channel, double-channel, or multi-channel wheels

A single-channel wheel is a type of wheel used in hydraulic pumps, designed with a single wide channel to allow the passage of liquids containing large solids or fibers. It is particularly effective in preventing blockages when pumping wastewater or loaded liquids.

Due to its ability to handle very high flow rates, the single-channel wheel is especially recommended for collective lifting projects.

A double-channel wheel has two channels to allow the evacuation of liquids loaded with solid particles. It is particularly effective for pumping wastewater or loaded liquids, reducing the risk of blockages.

The double-channel wheel sucks in and discharges particle-laden water without shredding it, in pipes with a free passage of 40 mm for maximum performance.

This technology provides a reliable and durable solution for optimal performance, particularly in commercial environments where large volumes of fluids need to be handled.

A multi-channel wheel is a wheel used in hydraulic pumps, featuring several channels to allow the passage of liquids, often carrying small solid particles. This design improves the efficiency of the pump by distributing the liquid flow through multiple passages.

Vortex wheel

The KX V6 wheel integrates vortex technology with a free passage of 50 mm, allowing it to process effluents and solid waste without blockages. Once in rotation, the wheel generates a powerful vortex effect that pulls solid materials into a rotating flow, facilitating their suction and evacuation without direct contact with the wheel's blades. As a result, the effluents are lifted through large-diameter pipes.

This innovative design enables the Vortex wheel to meet the most demanding applications, particularly in environments where solid or fibrous objects may be present in wastewater.
