Replacement support for VPA20 Series vertical pressure filters
The DOFIL VPA20 Series page covers independently manufactured aftermarket replacement support for vertical pressure filter plates, including VPA1530 and VPA2040 references. These plates work as part of a coordinated plate pack, so replacement review must consider the installed machine, plate sequence, membrane arrangement, process openings, lifting method and filter-cloth interface together.
A series name is useful for initial identification but is not enough for production. DOFIL compares the existing drawing, used sample, front and back photos, overall dimensions, plate thickness, openings, connection points, sealing areas and operating conditions before confirming a supply route.
Real VPA20 Series plate and field installation photos
The supplied workshop and field images show visible differences between plate references as well as the practical handling conditions around lifting, plate-pack access and site installation.

What is a VPA20 Series filter plate?
A VPA20 Series filter plate is a plate-pack component used in vertical pressure filtration. Depending on its position and function, the component may provide structural support, filtration or drainage surfaces, membrane action, process openings and interfaces for cloth or sealing elements. The plate set operates as a system rather than as unrelated individual parts.
VPA1530 and VPA2040 references can differ in overall geometry and interface details. The visible appearance in a photograph therefore supports identification, while the drawing and physical dimensions determine whether a replacement can be manufactured for the installed equipment.
VPA1530 and VPA2040 series references
| VPA1530 reference | Used for initial identification of the plate body, filtration face, central opening and visible handling interfaces shown in the supplied image. |
|---|---|
| VPA2040 reference | Used for initial identification of the plate surface, membrane components, opening arrangement and field plate-pack configuration shown in the supplied images. |
| Final selection | Confirmed from the original drawing, sample, plate position, dimensions, machine interfaces and actual process data. |
Critical replacement confirmation points
- Plate geometry: length, width, thickness, edge profile and plate position must match the installed plate pack.
- Filtration face: drainage texture, active area and cloth support must follow the original functional arrangement.
- Openings and connections: process ports, passages and connection details must align with adjacent components.
- Membrane arrangement: membrane shape, edge fixing and process-medium path require comparison with the existing component.
- Support and lifting: lifting points, handling direction and support contact must suit the machine and maintenance method.
- Sealing and cloth interface: sealing areas, cloth position and fixing details are checked to reduce leakage and installation risk.
Typical application review
| Mining tailings | High-volume dewatering where plate-pack condition, cycle stability and site maintenance access matter. |
|---|---|
| Mineral concentrate | Filtration reviewed according to particle condition, process pressure, washing steps and target cake moisture. |
| Coal and fine slurry | Fine-particle duties where cloth condition, drainage surfaces and process settings influence performance. |
| Industrial residues | Replacement projects where the existing machine interfaces and operating sequence must be retained. |
Why field installation evidence matters
Field photos reveal information that a product image cannot show: lifting clearance, maintenance access, plate-pack orientation, nearby structures and the way each component enters the machine. These details help define packing, lifting protection and installation planning before shipment.
Replacement verification process
- Identify the machine, series reference, plate position and replacement quantity.
- Collect the original drawing, used sample and clear front, back, side and connection photos.
- Confirm overall dimensions, thickness, openings, edge profile, lifting points and support interfaces.
- Review plate-pack sequence, membrane arrangement, cloth fixing, sealing and adjacent components.
- Check slurry, temperature, pressure, process medium, cycle and cake-moisture target.
- Confirm inspection, packing, lifting protection, delivery country and field installation plan.
Signs that a plate or membrane component needs review
Review is recommended when the plant finds cracking, permanent deformation, damaged drainage surfaces, membrane tearing, edge separation, recurring leakage, blocked passages, irregular cake formation or plate-pack misalignment. Cloth condition, process pressure and adjacent components should be checked at the same time.
Information required for an accurate quotation
Send the machine manufacturer and model, VPA series reference, plate position, original drawing, front and back photos, overall dimensions, thickness, opening and connection details, membrane photos, required quantity, slurry, temperature, operating pressure, cycle information, failure photos and destination country.
Frequently asked questions
Is the DOFIL VPA20 Series plate an original OEM plate?
No. DOFIL supplies independently manufactured aftermarket replacement components. Compatibility is confirmed from drawings, samples, photos, dimensions and operating data.
Can a VPA20 Series plate be quoted from the model name alone?
The model reference supports initial identification, but final quotation requires the existing plate geometry, openings, membrane arrangement, lifting details and machine interfaces.
Does the VPA20 Series page cover VPA1530 and VPA2040 plates?
Yes. VPA1530 and VPA2040 are included as series references. Each installed plate must still be checked independently before replacement production.
Can DOFIL support field replacement of a complete plate set?
DOFIL can review individual plates, planned spares, membrane-related components or a complete plate-set requirement according to the maintenance plan and confirmed interfaces.
