BDP manually operated hydraulic screen changers

Simple construction, rationality, maximum ergonomics for the processing of highly sensitive polymers.

The BDP screen changers type are characterized by simple design, ergonomics and rationality with which they were designed. They represent the hydraulic evolution of the manual screen changers and are suitable for the processing of highly sensitive polymers due to the specific temperature control of each filter holder. If necessary, for space or place reasons, the manual pump can be mounted separately. Available with filtering masses from Ø 45 to Ø 160 mm are equipped with a cable channel in the bottom that conveys the power cables and thermocouples in a junction box, located next to the hydraulic cylinder. This prevents dangerous overheating of the electrical system, ensuring maximum reliability.

faq

BD Plast is an Italian company founded in 1986, specialising in the design, manufacture and sale of filtration systems for plastic polymers. Its product range includes manual, hydraulic and continuous-flow filter changers, static filters, components for extrusion lines and accessories. With 40 years of experience, the company manages the entire process: from engineering to on-site installation.

The manual filter changer is the most cost-effective solution, suitable for standard production runs where a brief interruption to the process is acceptable. The hydraulic filter changer allows filter elements to be replaced whilst the plant is running, making it ideal for high production capacities. The continuous-flow filter changer, on the other hand, ensures a perfectly uninterrupted flow of polymer, eliminating waste and interruptions in the production cycle: it is the ideal choice for lines where process consistency is critical.

The Clean Changer is BD Plast’s patented innovation, designed specifically for the extrusion industry. It is a high-performance solution that meets the quality and continuity requirements of the most advanced production lines. For technical details and to assess its suitability for your process, please contact our sales or technical team.

The range is much broader. In addition to various types of filter changers, BD Plast manufactures adaptors, bends, necks, accessories, support trolleys and hydraulic power units. Each component is designed for maximum integration into extrusion lines, whether for cast film, blown film or coating lines.
