Import Beam-Pumping Units — Buy in Bulk from Supplier in China

Shengli Petroleum Machinery manufactures beam-pumping units for oil extraction operations, with its base in Dongying, Shandong Province. These units convert rotational motion into reciprocating vertical motion to drive downhole pumps. The supplier's description emphasises robust construction for harsh environments, precision engineering, and adaptability to varied well conditions. Load capacity and stroke length are not specified in the source data, so buyers should request these critical parameters directly.

The units are built with advanced technology intended to reduce vibration and mechanical stress during operation. Typical beam-pumping units in this category employ API standard structural steel for the frame, with alloy steel crankshafts and fibreglass or steel walking beams depending on the model series. Standard configurations include conventional crank-balanced units, air-balanced units, and Mark II units with optimised torque curves. The gearing system typically uses helical gears with hardened tooth surfaces to withstand cyclic loading over extended service intervals.

These units serve onshore and offshore oil fields where rod-pumping artificial lift remains the primary extraction method. Buyers include national oil companies, independent operators, and oilfield service contractors. The supplier mentions FOB and CIF incoterms, with L/C and T/T payment options, though exact pricing and lead times require direct confirmation. ISO and CE certifications are claimed but should be verified with certificate numbers before contracting.

Shengli Petroleum Machinery operates from Shengli Industry Zone in Dongying, 257000, China, placing it within one of China's concentrated oilfield equipment manufacturing regions. The supplier holds a 'harbor' trust tier with a response rate of 0.00 and zero recorded average response hours, which indicates minimal engagement data is available. The 'imported' supplier tier suggests this profile was established through import records rather than direct platform registration. Buyers should treat verification signals as limited and conduct independent due diligence.

The source description positions the company as offering flexible MOQ options and global shipping capabilities, though no specific production capacity, workforce size, or year of establishment is provided. The address references Shengli Industry Zone, which is associated with the larger Shengli Oilfield complex, but this does not confirm proprietary manufacturing facilities. Buyers should request factory audit reports, quality management system certificates, and reference installations before committing to large orders. Direct communication with the supplier is essential to confirm technical capabilities and current production schedules.
