Northern 4800 Crude Oil Injection Pump
Northern Pump, successfully completed a field overhaul project for a key crude oil pipeline customer. The completely custom 4800-07-D1761 gear pump is installed on an offshore oil platform located approximately 85 miles south of Galveston, TX.
This custom gear pump is installed on a series of pig launchers that are used to maintain and clean a crude oil pipeline. This high pressure pump allows the customer to inject the residual crude oil directly back into the pipeline. This provides for a safe and environmentally friendly method for handling excess crude oil generated through the pigging process.
In order to support operational objectives of the pipeline customer, two members of the Northern team were flown out to the platform to execute the field overhaul. All of the replacement parts accompanied the team, along with the calibrated tools required to properly assemble the pump. Because of the modular design of the liner plate equipped pump, the total weight of the replaced components and required tools was less that 50 pounds. This can be an extremely important factor when traveling offshore by helicopter. This pump was disassembled, analyzed, and re-assembled in less than three hours.
Northern Pump continued to support the pipeline operator by providing a custom manual, that describes the proper field overall method. This manual included a complete breakdown of all pump components. Spare parts kits and other replacement components are always readily available for all custom Northern Gear Pumps.
The 4800-07-D1761 is designed to pump 20-24 Gallons per Minute of Crude Oil at 1850 PSI discharge pressure. The pump unit is equipped with a 40 horsepower explosion proof motor and featured a custom Ring Type Joint suction and discharge plate. This plate was manufactured from a wrought bar of 1018 steel to eliminate the need for all welds and castings. The pump was also finished with a special paint system and was hydrostatic tested at the factory to 2653 PSI. Every Northern 4000 series pump and vertical unit are performance tested to meet the exact duty conditions of the customer’s application.
