200mm EPDM Closed-Cell Foam Vacuum Cup Seal

This large-diameter 200mm EPDM closed-cell foam vacuum cup seal is optimized for industrial lifting of heavy, textured and uneven products. The compressible foam creates broad surface contact and adapts to irregularities that can prevent conventional rubber suction cups from forming a dependable seal.

Typical applications include rough-cut wood, concrete blocks, quarry stone, brick, diamond plate, embossed materials and other coarse or uneven products handled by automated or manually operated vacuum lifting systems.

This page includes calculated theoretical lifting force at 80% vacuum in metric units and 24"Hg in imperial units.

Estimated Theoretical Lifting Force

The lifting force is calculated using the full nominal 200mm circular sealing area. The metric calculation uses 80% vacuum, while the imperial calculation uses 24"Hg. At sea level, 24"Hg produces an effective pressure differential of approximately 11.76 PSI.

Lifting Force Calculation

Calculation Step Metric Imperial
Nominal Diameter 200mm / 20cm 7.874"
Nominal Radius 10cm 3.937"
Nominal Area π × 10² = 314.16cm² π × 3.937² = 48.69in²
Vacuum Level 80% vacuum 24"Hg
Effective Pressure Approximately 0.8kg per cm² 14.7 PSI × 0.8 = 11.76 PSI
Estimated Theoretical Lift 314.16 × 0.8 = 251.3kg 48.69 × 11.76 = 572.6lb

Important: The calculated lifting force is theoretical and assumes that the complete nominal 200mm circular area is exposed to vacuum. The actual effective vacuum area may be smaller depending on the seal profile, mounting plate and internal opening.

An appropriate engineering safety factor must always be applied. Actual lifting capacity depends on surface texture, air leakage, seal compression, vacuum flow, load orientation, acceleration and operating conditions.

Typical Applications

  • Rough-cut wood and sawmill timber
  • Raw lumber and construction wood products
  • Concrete blocks and textured precast products
  • Quarry stone and natural stone slabs
  • Brick, pavers and masonry products
  • Diamond plate and embossed sheet metal
  • Corrugated and ribbed surfaces
  • Heavy industrial pick-and-place systems
  • Manual vacuum lifting equipment

Why Use a 200mm Closed-Cell Foam Vacuum Seal?

The large 200mm diameter provides increased nominal contact area for handling larger and heavier workpieces. The foam compresses around grooves, raised patterns and irregular surface profiles that can cause leakage when using a conventional rubber suction cup.

Closed-cell EPDM foam helps restrict air movement through the seal material while providing the flexibility required to establish contact on rough, coarse and embossed surfaces.

The vacuum source must provide sufficient airflow to compensate for leakage around highly textured workpieces. Application testing is required before establishing the safe working load.

EPDM Foam Material Information

EPDM closed-cell foam rubber provides flexibility, resilience and compressibility for industrial vacuum handling applications involving uneven workpieces. Its compliant construction allows the seal to adapt to changing surface heights and irregular product profiles.

Material compatibility should be confirmed before exposure to oils, chemicals, elevated temperatures or specialized production environments.

Frequently Asked Questions

What surfaces is this 200mm EPDM foam seal designed for?

It is designed for rough, coarse, textured and uneven materials such as rough-cut wood, concrete blocks, quarry stone, brick, pavers, diamond plate and embossed industrial products.

How much can the 200mm foam vacuum seal lift?

Using the full nominal 200mm circular area, the calculated theoretical lifting force is approximately 251.3kg at 80% vacuum or 572.6lb at 24"Hg. These figures are not safe working load ratings.

How is the metric lifting force calculated?

A 200mm diameter equals 20cm and has a nominal circular area of approximately 314.16cm². At 80% vacuum, the theoretical force is 314.16 × 0.8, which equals approximately 251.3kg.

How is the imperial lifting force calculated?

The 200mm diameter equals approximately 7.874 inches, producing a nominal area of 48.69 square inches. At 24"Hg, the effective pressure is approximately 11.76 PSI. Therefore, 48.69 × 11.76 provides a theoretical force of approximately 572.6lb.

Is this foam seal intended for rough or porous materials?

This foam seal is primarily designed to conform to rough, textured and uneven surfaces. It should not be selected solely because a workpiece is porous. Highly porous materials require a vacuum source with sufficient flow to compensate for air passing through the product.

Why could the actual lifting force be lower than the calculated value?

Actual force may be reduced by the internal vacuum opening, surface leakage, incomplete seal compression, contamination, acceleration, side loading, vacuum losses and variations in operating altitude.

Does a safety factor need to be applied?

Yes. The stated lifting figures are theoretical. An appropriate engineering safety factor must be applied based on load orientation, acceleration, surface condition, leakage, vacuum level and the risk of injury or product damage.

Is this a complete vacuum cup assembly?

This product is an EPDM foam replacement seal. The compatible vacuum cup body, backing plate, fitting or complete vacuum assembly may be supplied separately unless specifically included in the product listing.
