Quintuple Frac Pump

Product Description:

QPI series cementing and fracturing pump is a high-tech product independently developed by BOMCO for the exploitation of unconventional oil and gas resources, such as shale gas, coal bed methane. The product meets the requirements of SY/T 7086 standard, and has the characteristics of long stroke, low pumping and high reliability, which satisfies the localization replacement requirements of cementing and fracturing pumps.

Performance Features

The design of "long stroke and low impulse" is adopted in achieving superior comprehensive performance.

The unique positive-skewed crank-link mechanism reduces the risk of burns on the crosshead and surface of copper guide plate.

The bearing bush with large contact surface is adopted to improve the working reliability of the bearing bush.

The design life of main bearing and gear is increased to 3000 and 10000 hours respectively, and the overhaul cycle of fracturing pump is greatly extended.

The service life of vulnerable parts is greatly extended with the new long-life pump valve case.

Triplex Drilling Pump

Drilling pumps of series F enjoy the right to use the API Spec 7K Monogram (certificate number: API 7K 0009), and as important equipment for oil and gas exploration and development, they can be used to deliver high-pressure drilling fluid to the bottom of the well to cool the drill bit and carry cuttings. Currently, triplex drilling pumps with a horsepower from 500 to 2200 are available.

Performance Features:

The power end eliminates axial force by adopting herringbone gear drive.

Alloy steel crankshaft.

Replaceable crosshead guide plate.

The frame is welded with steel plate and has high strength, good rigidity and light weight.

The packing of the pony rod is a double-layer sealing structure with good sealing.

The power end is lubricated by combining forced lubrication and splash lubrication.

Pump valves at the hydraulic end are arranged in “I” or “L” type.

Three cylinders of the same pump can be exchanged.

Quintuple Drilling Pump

Product Description:

As high-tech products independently developed by BOMCO, quintuple drilling pumps of QDP series can meet requirements of API 7K, have characteristics of small pressure fluctuation, stable operation and long life of vulnerable parts and can be used for drilling operations such as high-pressure jet drilling, horizontal wells with large displacement, deep wells, ultra-deep wells and offshore platforms.

1600 HP, 2200HP, 3000HP

Performance Features:

The theoretical displacement is about one third of that of the triplex pump, and the pulsation dampener for exhaust can be canceled.

Spherical hinges are used to connect the crosshead and the pony rod to solve the problem of eccentric wear between the piston and the cylinder sleeve.

The service life of vulnerable parts at the hydraulic end is long.

The pump unit adopts modular design and is compact in structure and suitable for operation environments such as offshore drilling platforms.

With gear transmission, the overall energy efficiency of the pump unit is improved by about 7%.
