Belt filters for industrial liquids – precise filtration & process security

Belt filters are indispensable for the continuous purification of liquids and ensuring stable processes. With SIEBEC’s CENTRIPURE™ systems, you have highly modular solutions at your disposal that reliably separate solids, oils, and sludge – and, if desired, also maintain a constant temperature. Benefit from low maintenance, maximum filtration performance, and individually tailored solutions.

CENTRIPURE™ – Belt filters for water treatment

A belt filter is an automatic filtration system for the continuous purification of liquids, especially in industrial applications such as cooling and lubricating fluids, process water, or galvanic baths. It is part of mechanical solid-liquid separation and operates with unwinding filter fleece (also known as filter belts or roll media), which filters solids out of the liquid.

This challenge is solved by a belt filter

Belt filters like CENTRIPURE™ address several challenges in industrial filtration processes. They reliably remove the finest particles and sludge through automatic belt and magnetic filtration. In oil-laden liquids, integrated microfiber elements and skimmers effectively reduce the oil content. The optional temperature control ensures consistent conditions in the process and protects against fluctuations. At the same time, the 100% filtered return prevents unplanned downtime and significantly reduces wear on machines and tools.

Belt filters for high-pressure cooling lubricants

The CENTRIPURE™ version for metalworking (e.g., grinding, milling, turning) was specifically developed for use with high-pressure cooling lubricants. The system filters liquids directly into a separate pure tank with an optional volume of up to 2000 liters. At the same time, it protects machine components, extends tool life, and reduces downtime through:

High-capacity filtration with FILTECH™ cartridges
Belt filter for sludge and chip separation
Integration of high-pressure pumps
Optional heat exchanger (immersion or external)
Flexible skimmers (floating & surface) for constant oil separation

Component	Description
Pure Tank	270–2000 l (depending on version)
Temperature Control	COOLTECH™ – Cooling or heating as needed
High-Pressure Pump Integration	HP machine pumps integrable directly into the system
Belt Filter + MAGTECH™	Pre-separation of chips & magnetic particles
Cartridges & Oil Separation	FILTECH™, OILTECH™, BAGTECH™, MAGTECH™ integrated
Portable or Stationary	Stationary or mounted on wheels for flexible machine connectivity

Belt filters for water treatment

The CENTRIPURE™ plant for water treatment processes offers a fully autonomous filtration unit with an integrated belt filter pre-stage. The liquid to be cleaned is filtered directly into a separate pure tank, ensuring a 100% clean return to the process. The system is available as a standard version with a 250-liter tank and two filter housings or as a custom special version with extended components:

Roll belt filter (BANDTECH™)
High-pressure pumps
Tank for sludge and chip separation
Temperature regulation (COOLTECH™)
Oil separation (OILTECH™)
Magnetic filter (MAGTECH™)
Cartridge filter (FILTECH™)
Bag filter (BAGTECH™)

Component	Description
Pure Tank	250 l (Standard) or custom (scalable unlimited)
Temperature Regulation	COOLTECH™ – for constant media temperature
Belt Filter	BANDTECH™ – automatic media feed
Magnetic Filter	MAGTECH™ – 3000–11000 Gauss, 5 kg particle capacity
Oil Separation	OILTECH™ – hydrophobic microfiber, 500 g = 6 l oil separation
Pre- & Fine Filtration	BAGTECH™ (150–600 µm), FILTECH™ (1–100 µm), tool-free

This is what distinguishes our bag filters

Bag filters are a proven and economical solution for the filtration of liquids in industrial processes. Their modular design, easy maintenance, and robust technology offer a multitude of advantages – especially from a business perspective:

100% filtered return – maximum process security

Through separate pure tank filtration, CENTRIPURE™ ensures that only fully purified liquid returns to the process. This reliably protects machines, tools, and components from contamination and ensures consistent production quality – without surprises or returns.

Modular & adaptable – scalable for any application

Whether a small individual machine or a large production line: CENTRIPURE™ can be flexibly tailored to your requirements. From tank size and filtering technology to integrated pumps or temperature regulation – you receive exactly the configuration that suits your process.

Minimal maintenance – tool-free & automated

The filter media used can be changed without tools, and the belt filter automatically transports used fleece sections. This reduces downtime, avoids operation errors, and saves valuable time in maintenance.

Energy & cost-efficient – economically sustainable

Fewer machine downtimes, longer tool service life, and optimized cooling or washing media permanently reduce your operating costs. At the same time, you conserve resources and increase the energy efficiency of your entire process.
