Qp-ms Pumps

Casting :
* Top centerline discharge, self-venting casing, arranged for back pull-out.
* Fully confined gasket.
* Full support under casing for maximum resistance to misalign and distortion from pipe loads ASA-150 Ib flanges standard, 300 Ib optional for working pressure to 26 kg/cm2 with 3 mm corrosion allowance.
* For maximum corrosion-erosion resistance casing is supplied without tapped openings, but gauge and drain plug openings are provided when specified.

Impeller :
* 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, and threads are sealed by PTFE O-ring. This eliminates projecting impeller nut and exposed threads from impeller eye.
* All impellers are statically and dynamically balanced.

Stuffing Box Cover :
* Stuffing box cover encloses back of casing, and contains stuffing box chamber. The cover is fastened to frame 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 temperatures services. Jacket can also be used for heating viscous or high freezing point liquids.
