Filter Plate and Cloth Measurement Guide

Before You Measure

The confirmed Shengqi plate range is a reference series of 250–2000 mm, with 1000 mm and 1250 mm examples appearing in available material. This range is not a promise that every press accepts every size. The press frame, plate design, chamber depth, handle arrangement, hole pattern, sealing edge, and operating conditions must be matched to the actual equipment.

Use millimetres for dimensions and label every photograph. A ruler or tape in the image helps, but a photograph does not replace written measurements. If a dimension is uncertain, mark it as approximate and include a close view for review.

• Camera or phone with the full plate and close detail capability.
• Tape measure, steel rule, callipers where available, and a marker or labels.
• The equipment nameplate, model, serial number, and any existing plate or cloth identification.
• A clean, safe sample or removable part when the original is available for inspection.

Filter Plate Measurement Steps

For a replacement plate review, the key question is not simply whether the outside dimensions look similar. The sealing profile must close with the mating plate, the feed and filtrate openings must align with the press, and the plate must suit the frame, closing arrangement, cloth attachment, and intended process.

• Step 1 — Photograph the nameplate and write down manufacturer, model, serial number, plate type, and any stamped code.
• Step 2 — Photograph the full front, full back, left and right sides, top edge, bottom edge, handles, sealing edge, recess, and corner details.
• Step 3 — Measure overall length and width across the plate body. Record where the measurement starts and ends; do not include handles unless they are part of the specified envelope.
• Step 4 — Measure plate thickness and the filter chamber depth or recessed depth. State whether the value is measured on a clean plate or a worn plate.
• Step 5 — Record every feed, filtrate, wash, air, or squeeze opening: position from two reference edges, diameter or shape, and whether it is through-hole, blind, threaded, or fitted.
• Step 6 — Describe the sealing edge, corner pads, handles, side rails, cloth supports, puller contact points, and any damage or permanent deformation.
• Step 7 — Count plates by type and identify any end plate or non-standard plate. Send the drawing, sample, or additional close-up when a hole position cannot be measured confidently.

Filter Cloth Measurement Steps

A cloth is a shaped component, not a flat rectangle. Measure it while identifying which side faces the slurry and how it attaches to the plate. A centre-feed cloth, corner-feed cloth, necked cloth, and cloth with separate top and bottom pieces may have similar overall dimensions but cannot be treated as interchangeable without checking the attachment and hole pattern.

• Photograph both sides of the cloth, the slurry-facing side, the clean filtrate side, all edges, the centre or corner opening, neck, eyelets, loops, ties, snaps, and sewn seams.
• Measure finished length and width, opening diameter or shape, neck length and width, edge allowance, seam position, and attachment spacing.
• Record whether the cloth is one piece, two-piece, back cloth, feed cloth, or a special arrangement around a membrane or support surface.
• Write down fabric material if known, weave or construction if known, filtration task, slurry solids, temperature, pH, and any washing or cleaning method.
• Explain whether the request is an original-specification replacement or a proposed change intended to address blinding, leakage, wear, or cake release. A change requires application review and may require a sample test.

Photo and Submission Checklist

Name files so the review team can connect each image to a measurement: customer_press-model_plate-front.jpg, customer_plate-hole-detail.jpg, or customer_cloth-slurry-side.jpg. Put a ruler in close-up images, keep the camera square to the surface where possible, and avoid glare on sealing faces. Include one wide image showing how the component sits in the press and one detail image for every unusual feature.

• Customer, company, country, contact name, email, and WhatsApp number.
• Press manufacturer, model, serial number, plate size or series if known, and total plate count.
• Plate length, width, thickness, chamber depth, holes, sealing, handles, and plate types.
• Cloth shape, dimensions, openings, neck, fixing, material, seam, and original sample availability.
• Slurry description, solids condition, temperature, pH if known, cycle information, cleaning practice, and the reason for replacement.
• Required quantity, target delivery location, desired original match or improvement review, and attached drawings or samples.

Review, Sample Confirmation, and Quotation

The review sequence is: identify the press, compare the dimensional record with photographs, check the plate and cloth interface, confirm materials against the service, request a drawing or sample where necessary, then confirm quantity and quotation scope. A dimensional match alone does not establish pressure suitability, filtration performance, chemical compatibility, or service life.

Do not place a batch order until the approved drawing, sample, or written dimensional confirmation covers the required plate and cloth types.

• Send measurement information and attachments through the request process at /request-a-quote/.
• Ask for replacement filter plates at /filter-plates/replacement-filter-plates/ or custom plates at /filter-plates/custom-filter-plates/.
• Ask for replacement cloths at /filter-cloths/replacement-filter-cloths/ or custom cloths at /filter-cloths/custom-filter-cloths/.
• For an uncertain dimension, send the original sample or a labelled sketch rather than guessing.
