NOV Mission Centrifugal Pumps American Manufacturer
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.
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 for centrifugal pump.
Derrick Centrifugal pump-USA Manufactuer
- Open impeller design
- Grease lubrication
- SKF premium bearings
- Tungsten carbide mechanical seal
Derrick offers a complete line of centrifugal pumps to accommodate a full variety of drilling applications. Sizes range from 2 × 3 to 6 × 8. Bare pumps, horizontal packages, and overhead belt drive configurations are available. Explosion proof electric motors are available up to 200 HP, in 1200, 1800 or 3600 RPM.
The Derrick Premium 250 pump series incorporates proven oilfield features including a heavy-duty 2-1/2” diameter shaft. Standard features include a replaceable casing wear pad, premium bearings and tungsten carbide mechanical seal. The Derrick Premium 250 pump parts are interchangeable with industry standard type pumps
Derrick’s large diameter shaft is designed with a replaceable shaft sleeve, allowing packing wear area replacement independent of the shaft. Minimal shaft deflection aids in packing or mechanical seal life. The Derrick Premium 250 replaceable casing wear pad allows worn area replacement without replacing the entire casing.
Premium bearings throughout include a double row ball-bearing inboard to accommodate large impellers. High thrust load, zero endplay angular contact bearings are utilized outboard. Grease type lubrication is standard and oil bath lubrication is also available.
Overhead belt drive packages are skidded, as shown, and include the Derrick Premium 250 pump, an explosion proof electric motor, belts and sheaves, and OSHA type belt guard. Starters are optional.
Horizontal packages are skidded, as shown, and include the Derrick Premium 250 pump, explosion proof electric motor, and coupling with OSHA type guard. Starters are optional.
Available on the website, Derrick offers a centrifugal pump-sizing calculator to assist in determining total dynamic head requirements, impeller sizing and proper line sizing. Please consult a Derrick representative for further information.
