Case Study: PLASMET HTE USED IN THE REFURBISHMENT OF A VOLUTE PUMP CASING

Volute pump casing on arrival at works and following refurbishment and coating with abrasion resistant Plasmet HTE.

Volute Casing Refurbishment

 Corrocoat coatings were used in the recent refurbishment and coating of a volute pump casing for a leader in the forest-based bio-industry.

The desired outcome being excellent abrasive resistance

The Solution

 The volute pump casing was rebated and pre-machined to accommodate the coating process, the pump was grit-blasted to ISO8501-1 internals and wetted areas to SA2½.

Multiple coats of Plasmet HTE were applied to achieve a minimum dry film thickness of 2.0mm.

Plasmet HTE is a solvent free, amine cured epoxy, containing stainless steel flakes and silicon carbide that gives excellent abrasion resistance in immersed environments. Plasmet HTE has been used in cyclones, chemical process vessels and sugar beet pumping drums amongst other applications.
