Sumps

The engineering challenge wet blasting at scale presents

Stainless steel fabrications for food and pharmaceutical environments must achieve Ra values between 0.25 and 0.6 microns to meet EHEDG cleanability requirements. Pickling introduces chemical hazards, dry blasting compromises the passive layer, and grinding leaves directional marks that undermine finish uniformity. The Leopard Sump is for fabricators who need to own this process and deliver it consistently.

Process control across large and irregular surfaces

The Leopard Sump operates two high powered blast guns, giving operators enough power to remove MIG and TIG weld discolouration and enough flow to get consistent finishes across large surfaces. Pinch valves allow the operator to select guns without changeover. 

Working with glass bead, ceramic media, aluminium oxide, or a combination, operators have the flexibility for cutting, polishing and cleaning in one machine.

Why Vapormatt

Wet blasting is a straightforward process, pump design, the slurry management, the filtration, and holding a consistent Ra across large surfaces is not. Vapormatt has been engineering that knowledge into its machines longer than any other manufacturer; the process has been widely imitated as a result. 

The Leopard Sump is the original: built, commissioned, and supported by the company that developed the first open sump format.

• Patented sump design: The low-profile doughnut sump holds working height to 700mm (27.6"), without pits or platform, protecting both your facility and your capital budget.
• Dual-gun versatility: Two nozzles with selectable intensity let a single operator move between aggressive weld treatment and fine surface conditioning on the same component, without changeover or reloading.
• Consultative supply model: Vapormatt supplies the sump, the pump, the filtration, and the process knowledge. Your team builds the enclosure to your facility's exact dimensions under Vapormatt's guidance. The result fits your requirements, not what the OEM offers.

The Vapormatt Promise: the machine meets the agreed specification, or we make it right.

The bottom line

Fabricators who depend on subcontract finishing carry the logistics cost, share the margins and risk delays when a deadline tightens. The Leopard Sump puts the process on your floor, under your control, from day one.
