Features & Benefits

Markets

Heavy duty casings and impellers.

Back pull-out to reduce maintenance down time.

Standard packed stuffing box or optional American-Marsh Series 820 component mechanical seal for both reliability and dependability. Carbon/Si-Carbide/Viton elastomers standard, with other faces and elastomers available. 850B cartridge mechanical seals are also available on request.

Available standard in Ductile Iron/304SS fitted or other alloy for application versatility.

Replaceable wearing components include optional casing wear plates to maintain peak efficiency.

Two vane, non-clog impeller design passes large spherical solids (through 7 inches on larger models) and "limp" media.

Impellers have front and rear pump out vanes to keep material from building up in those areas.

The 125 lb. ANSI suction connection has a removable, oval clean-out plate to provide visibility and accessibility to the impeller vanes. The suction cover also has a cast integral foot for casing support. The 125 lb. ANSI tangential discharge connection also has a removable, oval clean-out plate to provide visibility and accessibility to the impeller vanes and casing cutwater. Case working pressures for all NCH models is 175 psi.

NCH power frames feature heavy duty, grease lubricated bearings and oversized shaft. All NCH pump models feature bearings with a minimum 50,000 hour design life.

Optional rigid carbon steel bedplate and OSHA coupling guard.
