    Centrifugal Pumps

    Centrifugal Pump SelectorThe National Oilwell Varco Mission centrifugal pump line has proven to be the best centrifugal design for handling abrasive mud. This pump line offers a broad selection of innovative features for a variety of routine, demanding, abrasive and corrosive applications. These pumps are designed for a wide range of flow rates, from a few gallons per minute to thousands of gallons per minute.

    During the 1950's the Mission™ 1780 type "W" pumps were introduced to replace duplex pumps while creating the first low pressure mud system. The use of a high quality, concentric type centrifugal pump allowed abrasive fluids to be mixed and transferred while reducing initial and maintenance costs for the drilling industry. The low-pressure mud system with Mission 1780 Type "W" centrifugal pumps became the industry standard.

    As well depths increased, so did the need for heavier mud weights. When the mud weight began exceeding 14 ppg, the need for a pump that could withstand greater horsepower loads arose. During the 1970's, Mission organized a design team that engineered the Mission Magnum. The Magnum was designed to have the same footprint, flange locations, and drive shaft diameter as the 1780 "W". This allowed a 1780 to be replaced by a Magnum without any skid modifications. The Magnums were engineered with a 2 1/2" shaft (3" between the bearings), double row bearings with an engineered life of over 2 years at 200 HP, larger impellers and heavier frames. The Magnum allowed drilling contractors to upgrade their centrifugal pumps and mix heavier fluids.

    National Oilwell Varco is dedicated to continual improvement of our product line and offering innovative solutions to service our customers.
