The five-cylinder configuration offers distinct advantages over traditional triplex designs:
Smoother flow output – five smaller pressure pulses per revolution instead of three larger ones
Reduced pressure pulsation – less stress on downstream equipment and downhole tools
Extended fluid end life – lower peak loads on valves and seals
Quieter operation – reduced vibration and noise

🏭 Sinopec Manufacturing Heritage
We're not a trading company – we’re a manufacturer with roots in Sinopec's engineering ecosystem. Founded in 1941, we’ve been building oilfield equipment for over eight decades. As a China Critical Technological Equipment Nationalization Base and National Hi-tech Enterprise, our quality systems, supply chains, and engineering standards meet the highest benchmarks.
🔧 Unmatched Fracturing Pump Legacy
SJ has been at the forefront of fracturing pump innovation since the 1980s – developing China's first 800HP, 1000HP, 1800HP, and 2000HP fracturing units, as well as the world’s first truck-mounted 2500HP fracturing unit. The SQP2500 continues this legacy as a core component of SJ's 2500-type fracturing equipment family.

Q1: What is a quintuplex pump, and why choose it over a triplex?
A: A quintuplex pump has five plungers instead of the three found in a triplex. The five-cylinder configuration delivers smoother flow output, reduced pressure pulsation, lower peak loads on valves and seals, and extended fluid end life. The result is quieter operation, reduced vibration, and longer maintenance intervals – critical advantages in long-duration fracturing campaigns.
Q2: What is the power output of the SQP2500?
A: The SQP2500 delivers 2500 HP (1866 kW) of maximum output power.
Q3: What is the maximum working pressure?
A: The SQP2500 achieves maximum working pressure of 140 MPa (20,000 psi) in truck-mounted configuration. Field operations have demonstrated continuous operation at 125 MPa (18,100 psi) .
Q4: What is the suction/discharge efficiency?
A: The SQP2500 achieves 95% suction and discharge efficiency – an improvement from the 90% typical of conventional designs. This 5% efficiency gain means higher effective displacement without increasing input power.
Q5: Has the SQP2500 been proven in extreme cold?
A: Yes. The SQP2500 has been fully validated for −45°C operations and has been successfully deployed in West Siberian extreme cold environments. SJ has established a national-level low-temperature impact testing laboratory to ensure reliable performance in Arctic conditions.
Q6: Has the SQP2500 been used in shale gas operations?
A: Yes. The SQP2500 has been extensively validated in long-duration shale gas operations across North America and China. It has been deployed in Fuling shale gas, Puguang Gas Field, and Tarim Tahe Oilfield.
Q7: What configurations are available?
A: The SQP2500 is available in truck-mounted, skid-mounted, and trailer-mounted configurations. The 2300-type fracturing skid features a split power skid and pump skid design with universal drive shaft quick-connect for smaller footprint and lighter weight.
Q8: Is an electric drive version available?
A: Yes. The SQP2500EG electric drive variant has been developed for all-electric "one-key” cementing equipment applications, featuring variable frequency electric drive pumping.
Q9: How many SQP2500-powered units have been delivered?
A: SJ has built and delivered over 300 of its 2500 Quintaplex Pump Fracturing Trucks. SQP2500H power ends and complete pump assemblies have also been exported to Eurasian markets.
