Klaus Union has delivered various vertically suspended pumps for ammonia applications of a new fertilizer plant in North Africa. The pumps are designed in both VS4 and VS6 design and come with different sealing types – simple stuffing box packings (following API 610) and magnet drives (following API 685), which are equipped with our new hybrid double containment shell.

This containment shell design combines two separate shells. The inner shell is a highly corrosion resistant metallic containment shell while the outer, secondary shell is a non-metallic containment shell made from heavy duty technical ceramics. The hybrid double containment shell meets API 685 § 3.66 “secondary containment system”.
