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 1 780 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 originally 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.
The 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.

Each pump contains the finest materials, engineering and craftsmanship available in the industry. Described are like features of these pump lines and unique features are described on the following pages.
National Oilwell Varco utilizes unique design features developed for slurries. Three major differences from most pump designs include the concentric casing, wider impellers and increased re-circulation areas. Each feature contributes to reducing wear when handling abrasive fluids.
All of the pumps feature a concentric casing. This casing averages 37% thicker than conventional pump casings, and up to 50% thicker for the larger, mud pumping models. They are pressure rated at 1 .5 times the flange rating and are designed with a 1 /8″ erosion allowance. The concentric style casing has proven to offer the greatest pump life and reduced downtime. The walls of a concentric style casing are an equal distance from the impeller throughout the impeller circumference, which results in a smooth flow pattern. A volute style casing has a cutwater point that disturbs the fluid flow pattern creating an eddy. The concentric casing eliminates vibration, turbulence and aeration that is caused by the cutwater point in conventional volute pumps. It also reduces the high bearing loads and shaft deflection even at near shutoff flows.
Wider Impeller, Increased Re-circulation Area National Oilwell Varco’s impeller design has wider vanes at the tip which decreases the velocity of the fluid exiting the impeller. This eliminates the abrasive jetting effect that is present with narrow impellers. The distance between the impeller tip and the casing is greater resulting in an increased re-circulation area. Lower velocity rates and increased re-circulation areas allow the exiting fluid to blend with the re-circulating fluid reducing turbulence and wear. The entrance shape of the impeller vanes is more tangential to the circumference of the suction creating a smoother flow pattern. Smooth flow is crucial when handling abrasive fluids.
The shaft is much larger in diameter than conventional pump shafts for heavy-duty performance, minimum deflection and increased operating life of the seal or packing. With a 2-1/2″ diameter at the seal area and 3″ diameter between the bearings these pumps can be direct connected or belt driven.

Since the NOV A1700-PT Triplex Mud Pump was built approximately 60 years ago, the industry has widely accepted the three cylinder or triplex style pump. Triplex mud pumps are manufactured worldwide, and many companies have emulated the original design and developed an improved form of the triplex pump in the past decade.
NOV A1700-PT Triplex Mud Pumps have many advantages they weight 30% less than a duplex of equal horsepower or kilowatts. The lighter weight parts are easier to handle and therefore easier to maintain. The other advantages include;They cost less to operate
One of the more important advantages of triplex over duplex pumps, is that they can move large volumes of mud at the higher pressure is required for modern deep hole drilling.
NOV A1700-PT Triplex Mud Pump is gradually phasing out duplex units. In a triplex pump, the pistons discharge mud only when they move forward in the liner. Then, when they moved back they draw in mud on the same side of the piston. Because of this, they are also called “single acting.” Single acting triplex pumps, pump mud at a relatively high speeds. NOV A1700-PT Triplex Mud Pump has three pistons each moving in its own liner. It also has three intake valves and three discharge valves. It also has a pulsation dampener in the discharge line.
