• Mission 1780 Type W

    The concentric casing long life design of the Mission 1780 Type "W" centrifugal pumps has virtually eliminated the high pressure duplex mud mixing system and has allowed operators to reduce their initial and operating costs.
    Description

    National Oilwell Varco's Mission 1780 Type "W" centrifugal pumps were utilized on the first low pressure mud system constructed in the early 1950's. Their concentric casing long life design has virtually eliminated the high pressure duplex mud mixing system and has allowed operators to reduce their initial and operating costs. Mission pumps were not only used on the first low pressure mud system but became and remain the leading pump of choice by drilling contractors around the world.

    National Oilwell Varco's Mission 1780 Type "W" centrifugal pumps feature a concentric casing that is equal in distance from the impeller O.D. on all sides. This creates a smooth flow pattern that is essential when handling abrasive fluids. The semi-open impeller design reduces stuffing box pressure and extends the wear plate and packing life.

    Typical Applications:

    • Various abrasive and corrosive slurries
    • Salt water
    • Hydrofluoric and sulphuric acids
    • Caustic soda
    • Black liquor
    • Mining slurries
    • Filter pump
    • Filter backwash pump
    • Transfer pump
    • Supercharging pumps for reciprocating injection pumps
