The advanced design Unit-Type rotor assembly, with impellers end channel rings mounted on e single, heavyduty shaft end with a smooth-bore outer casing, is the some type es that used by IngersoH-Rend in the high-pressure CHTA ond HMTA lines. The result of this modern con struction is a dependable, simpler and more rugged unit that requires minimum attention and maintenance. CNTA pumps ore multi-stage, horizontally split units, with single-suction impeller groups placed back-to-back to eliminate hydraulic thrust. They are (available in 4, 6 and 3 stages for pressures from 100 to 600 psl, in capacities from 50 to 700 gpm. Your l-R representative will be glad to give you the complcto story.
