Axial Flow Pump - MAF Series
Axial Flow Pump - MAF Series
MEGATECH PUMP is unmatched in the industry for high volume/low head pumping requirements...especially when corrosive and/or abrasive solutions are involved. Extended service life, mechanical reliability, custom engineering, and a wide range of materials allow the Model MAF SERIES to stand out as the leader in the field.
For continuous circulation of corrosive/abrasive solutions and process wastes. Proven performance in a variety of services around the world.
Casting
Chemical Process pump having top centerline discharge, self-venting casting, arranged for back pull-out. Fully confined gasket. Foot support under casing for maximum resistance to misalignment and distortion from pipe loads. ANSI-B-16.5 (Class 150) flanges standard, ANSI-B-16.5 (Class 300) optional for working pressure to 2550 kPa 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
Pump Impeller matched to casting for high efficiency and low NPSH. Fully open, has partial shrounds 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 solid handling ability. Impeller is locked on shaft with impeller lock-nut and are sealed by Teflon (PTFE) gasket. State of the art casting methods provide smoothest possible surfaces for highest efficiency. All impellers are statically balanced.
Shaft
Pump having a single piece shaft is designed for 0.05 mm maximum diflection at stuffing box face. all critical surfaces ground to less than 0.8 micron.
