Maxum OH1

ASTM F998 Close-Coupled Centrifugal Pump

Our end-suction pump for handling freshwater, seawater, and light hydrocarbons in commercial marine and naval applications.

Commercial marine and naval applications

Conforming to the requirements of ASTM F998, including the Navy supplement, hydraulic performance extends to 5,000 GPM and 713 feet of head. This range is covered by 24 sizes in 316 SS and CD4MCuN duplex SS as the standard materials. Units can be mounted either horizontally or vertically.

Designed to meet Naval Requirements including MIL-S-901 Shock, MIL-STD-167-1 Type I Environmental Vibration, MIL-STD-740-1 Airborne Noise and MIL-STD-740-2 Structureborne Noise. All models are back pull-out designs with replaceable wear rings, encloded impellers and balancing holes with dual volute casings as required. These features combine to produce shaft deflections of less than 0.002″ at shutoff, and overall, offer some of the most efficient hydraulics to be found in a pump of this type anywhere.

Connections ANSI Flanges
Bearings Grease Lubricated

FEATURES

1. Connections: Most sizes rotatable in 90° increments for added flexibility in meeting shipboard piping configurations.

2. Casing: Short impeller overhangs maintain shaft deflections under 0.002″. All drain, vent and gauge connections are straight-thread, O-ring type for positive sealing.

3. Impeller: Enclosed type with features to reduce axial thrust loads, for longer component life.

4. Composite Internals: Composite impellers, wear rings and shaft sleeves per NAVSEA drawing 803-7226047 reduce corrosion, increase pump life, and greatly decrease pump weight.

5. Back Pull Out: Allows inspection, maintenance and overhaul of all rotating elements, including the shaft, impeller and mechanical seal, without disturbing system piping.

6. Mechanical Seal: In accordance with ASTM F1511, with carbon on silicon carbide faces as standard, and auxiliary throttle bushing for added protection from catastrophic seal failure. Cyclone separators provided on all seawater applications.

7. Close Coupled Design: Smaller and lighter envelope than traditional split-case or frame-mounted designs, totally eliminating issues with pump bearing, shaft coupling, and pump/motor alignment.
