Hydraulic Filter – Slide Plate Type Hydraulic Screen Changer for Plastic Extruders
The GM-SSP series slide plate type hydraulic screen changer is widely used in corrugated pipe extrusion machines. Typically, two sets of this screen changer are installed to filter both the inner and outer walls simultaneously, and these can be controlled by a single hydraulic unit. This system is also suitable for various other applications where filtration is required. Its proven technology and competitive pricing have made it popular worldwide. It serves as a fundamental filtration tool for extruders. However, with technological advancements, many users are now switching to continuous screen changers like our double piston model.
Main Features of the Plate Type Hydraulic Screen Changer
1. Fast and Efficient
- The transition from the filtering screen to the clean screen takes less than 2 seconds.
- Extraction and replacement of screens are quick, allowing maintenance to be completed in minimal time.
- The fast changeover ensures that the extruder operation remains uninterrupted.
2. Flexible Installation
- Can be installed vertically, horizontally, or at an angle.
- The hydraulic cylinder can be positioned on either side or vertically.
- Multiple screen changers can be driven by one hydraulic unit.
3. Safe Operation
- Equipped with safety devices to ensure secure use.
- Doors and hydraulic units have safety blocking systems to prevent accidental opening during maintenance.
- The accumulator block prevents the hydraulic unit from exceeding the set maximum pressure.
- Provides a perfect seal during the sliding of the plates.
