    Description

    National Oilwell Varco's Mission 1180 Type "S" centrifugal pumps are designed with a concentric casing and semi-open impeller that makes them an ideal selection when handling clear or abrasive fluids. The concentric casing is equal in distance from the impeller O.D. on all sides. This creates a smooth flow pattern that reduces eddy flow patterns and wear. The semi-open impeller design reduces stuffing box pressure and extends the wear plate and packing life.

    National Oilwell Varco's Mission 1180 Type "S" pumps are used for a variety of applications, from liner wash systems to small mud systems for the micro tunneling industry. Our experienced technical sales team can assist in the selection of the proper model and size of pump to meet the application of your choice.

    Features/Benefits

    The concentric casing and semi-open impeller offer several benefits:

    • Ideal for handling clear or abrasive fluids
    • Creates a smooth flow pattern that reduces eddy flow patterns and wear
    • Reduces stuffing box pressure and extends the life of the wear plate and packing

    Specifications

    • Available in sizes ranging from 1x1-1/2 C to 3x4 R11
    • Flow rates from a few gallons per minute to 800 GPM
    • Head pressures from 8 to 350 feet
