The industrial filter offers a separate collection area for separated solids, preventing direct impact on the filter element. Coarse and heavy particles are collected separately without clogging the filter element. This prevents blockages in the filter, extends operating times and reduces maintenance costs by up to 40 %.

Thanks to the housing cover with handle, the filter element can be replaced in less than 15 minutes - without complicated removal. The sophisticated design with a fixed dirt collection container and no moving parts also reduces wear. This saves you up to 90 % work, up to 20 % maintenance costs and around € 86,000 over the service life.

The compact inline design allows easy installation of the industrial filter into existing systems without extensive modifications or major conversions. The plate filter can also be flexibly installed on the suction side of the pump, protecting sensitive pump systems and extending their service life.

 

The low-wear design without moving parts and the robust monolithic cast iron housing with silicate-based cast skin ensure maximum resistance to external and media-induced influences. This extends the service life of your filter system, reduces operating costs by up to 30 % and halves disposal costs.

 

The inline construction at the same height enables simple and time-saving installation - without having to relocate the pipes. This reduces your planning and installation costs by 30-40 % and saves you up to two days for commissioning your system.

The pre-assembled and tested plug-and-play unit enables direct commissioning without additional wiring or testing on site. This means your system is ready for use up to 40 % faster, installation errors are minimized and overall costs are significantly reduced.

Individual Filtration solutions

Customized special solid-liquid separation solutions are developed for specific customer requirements. These may involve special materials, custom dimensions or application-specific adaptations. This ensures that the water filter can be perfectly integrated into the existing system and delivers optimal filtration performance for your industrial application.

Flexible cleaning

The filter can be cleaned manually or fully automatically, depending on the operating requirements. Manual cleaning is particularly cost-effective for simple applications, while automatic backwashing - controlled by a control system - ensures continuous filtration. This allows you to increase the operating efficiency of your company with maximum flexibility.

Comprehensive protection for sensitive systems

Our filter systems reliably protect industrial components such as plate heat exchangers, spray nozzles, pipe systems, pumps and microfiltration units. They contribute to environmental protection by safeguarding end products and water resources from contamination. Thanks to their high filtration performance, they are suitable for cooling water, river water, sea water, ballast water, process water, oils, emulsions and water infested by mussels. Even drinking and efluent water can be effectively treated. This ensures sustainable use and reliable solid-liquid separation.

Optimized backwash technology for continuous filtration

WHY A BACKWASH FUNCTION?

A backwash function ensures continuous cleaning of the filter element and prevents clogging. Differential pressure measurement detects the degree of contamination and activates the backwash process when needed. This keeps filtration efficient at all times- without the need for manual intervention.

HOW DOES THE BACKWASH FUNCTION?

As soon as the defined differential pressure is reached, the motor-driven backwash valve opens. The high flow velocity flushes out dirt particles from the filter. According to Bernoulli’s law, a vacuum is created that draws clean water through the filter element in the opposite direction of filtration, removing accumulated particles. After 15–20 seconds, the process ends automatically – without interrupting coarse filtration.

The filtration process of the plate filter



The raw water enters the industrial filter via the inlet flange and flows through the filter element.

Dirt particles are reliably filtered out, while purified water exits on the clean water side. Coarser particles settle in the dirt collection area.

A differential pressure measurement continuously monitors the contamination level of the filter element. When a defined limit value is reached, the backwash process is activated automatically.

The motor-driven backwash valve opens, generating a high flow velocity. Deposited contaminants are released and flushed out through the backwash outlet.

According to Bernoulli's law, a vacuum forms in front of the filter element, causing clean water to flow in the opposite direction of filtration and effectively removing any remaining particles.

After 15–20 seconds, the backwash valve closes automatically. Filtration remains active throughout the entire process, ensuring continuous operation.

The Filter element

The filter element is made from a reinforced wedge-wire screen construction, allowing it to withstand even high differential pressures. Thanks to the integrated handle, it can be removed quickly and effortlessly from the filter housing during inspections. Depending on the requirements, the filter element can be designed in various stainless steel grades to ensure optimal durability and filtration performance.

Electrical control

The backwash process is initiated automatically – either time-controlled or based on the differential pressure. This enables fully automatic filter operation. The standard control system communicates with the customer's process control system (PCS) and provides the following signals: 

  • Collective fault 
  • Operational readiness 
  • Filter flushing mode 
  • External triggering of filter backwash 
  • External release of the filter backwash

Differential pressure measurement

The very low differential pressure in clean condition enables the protected installation of a pump on the suction side - without pre-filtration. Coarse particles are kept out, which minimizes wear on the pump. An integrated differential pressure measurement with visual display and freely adjustable switching contacts also ensures precise monitoring, automatic flushing and an alarm signal in the event of critical pressure conditions. This extends the service life of your pump by up to 5 years and increases the efficiency of your system.

Venturi nozzle with backwash valve

The Venturi nozzle is specifically tailored to the customer’s operating conditions to ensure an optimal flushing water quantity and to avoid pressure fluctuations in the pipe network. The backwash device is equipped as standard with an electric or pneumatic actuator, ensuring precise and reliable control of the backwash process.
