Air-Operated Drum Pump resists isocyanate crystal formation.

Press Release Summary:

Constructed to combat effects of isocyanate crystals that form on pump surfaces when changing drums that contain 2-component coatings using isocyanate in hardener component, OP-232C limits crystal formation to non-critical areas; rods and packings remain free of crystals. Quick release bung adapter facilitates drum changes, and hoses can remain attached to further limit crystal formation. Construction features allow periodic cleaning of critical pump passages.

Air Operated Drum Pumps for Isocyanate

Many two component coatings use isocyanate in the hardener component. When changing drums, isocyanate forms sharp crystals on pump surfaces, damaging packings, and shortening pump life. IPM's OP-232C pump limits crystal formation to non-critical areas, allowing rods and packings to remain free of crystals, improving packing life. Quick release bung adapter provides fast drum changes, and hoses can remain attached, further limiting crystal formation. Improved construction features allow periodic cleaning of critical pump passages to provide virtually unlimited service life.

IPM manufactures air operated pumps for handling paint, coatings and other fluids.
