Pull Action Filter centrifuges DZF
The vertical basket centrifuges of the type DZF Pull Action Filter centrifuges are designed for different applications in solid-liquid separation. The discharge system is a Ferrum innovation (patented) and functions without using a scraper knife. Application-specific feed and wash systems, CIP systems and Ferrum InertoSafe® systems may be adapted according to your requirements.
The Pull Action Filter centrifuges are used in the pharmaceutical and chemical manufacturing industry with products sensitive to crystal breakage and/or with thixotropic behaviour.
Features
- Discharging without scraper knife
- Gentle product treatment - no crystal breakage
- No residual heel since this is also removed by stretching the filter cloth
- The filter cloth is only stretched for discharging, not inverted. Therefore, the mechanical strain of the filter cloth is comparatively small.
- The discharge sequence is carried out within the basket. For this reason, the centrifuge housing remains free from centrifuged product.
- The dimensions and the weight of the Pull Action Filter centrifuge are significantly smaller than for a comparable horizontal filter centrifuge.
- The Pull Action Filter centrifuge is less expensive than a comparable horizontal centrifuge with inverting filter cloth mechanism.
- Suitable for potentially explosive areas according to directive 2014/34/EU (ATEX)
