Metallic Pump - Chemical Process Pump

Impeller matched to casing for high efficiency and low NPSH. Fully open, has partial shrouds for maximum vane support without high thrust inherent in closed impellers. Stuffing box pressure reduced and entrance of solids prevented by back pump-out vanes. Large smoothly contoured-flow passages combine best slurry and solids handling ability.

Impeller is screwed on shaft with rotation to tighten and threads are sealed by TFE O - ring Cast-in impeller nut makes removal easy and minimizes friction losses. This eliminates projecting impeller nut and exposed threads form impeller eye. State of the art casting methods provide smoothest possible surface for highest efficiency. All impellers are statically and dynamically balanced.

STUFFING BOX COVER

Encloses back of casing and contains stuffing box chamber. Cover is fastened to from or adapter so that a spare back pull-out assembly can be stocked completely assembled. Cover can be supplied with jacket for cooling stuffing box chamber in high temperature services. Jacket can also be used for heating viscous OR high freezing point liquids.

Packed box has five rings of packing and a lantern ring. Quench gland with water taps and an auxiliary ring packing is standard. Gland is split for easy removal. Tapped openings to lantern ring permit " IN AND OUT "sealing, external flushing or lubrication as required.

Stuffing box is completely machined for mechanical seal installation, either originally or as a field conversion. Inside, Ou
