The STP3300 features a long-stroke design that reduces the number of reciprocation cycles required to achieve a given flow rate. This translates to:
Reduced wear on fluid end components – longer stroke means fewer cycles, less fatigue
Smoother flow output – reduced pressure pulsation for more consistent downhole fracturing
Extended maintenance intervals – less frequent fluid end overhauls
Improved overall reliability – proven in million-stroke type testing

🏭 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 STP3300 continues this legacy as the pump that powered the world's first 3000HP fracturing truck.
🏆 National Recognition
The STP3300 and the 3000HP fracturing truck program were developed under the National "12th Five-Year” Major Science and Technology Project. The project achieved:
15 key technology breakthroughs in ultra-high-pressure, high-displacement fracturing
4,380 sample/tests and 640 hours of component and system validation
6 STP3300 plunger pumps and 4 SYL3000 fracturing trucks manufactured
🌍 Global Export Track Record
SJ's fracturing equipment has been widely exported to North & South America, Russia, the Middle East and North Africa, serving 43 countries and regions worldwide.

Q1: What is the power output of the STP3300?
A: The STP3300 delivers 3000 HP (2237 kW) of maximum output power – a significant step up from the 2500HP standard that previously dominated the industry.
Q2: What is the maximum working pressure?
A: The STP3300 is rated for a maximum working pressure of 140 MPa (20,000 psi) . In field operations, it has successfully operated at 84 MPa (12,180 psi) during a 14-hour continuous acid fracturing job.
Q3: What is a triplex pump, and why choose it?
A: A triplex pump has three plungers arranged in a single-acting configuration. The STP3300’s long-stroke triplex design reduces the number of reciprocation cycles, resulting in smoother flow, reduced component wear, and longer maintenance intervals compared to shorter-stroke designs.
Q4: Has the STP3300 been proven in the field?
A: Yes. Six STP3300 plunger pumps were manufactured under China's national major project. They have been field-proven in:
CNPC’s Shutan 1H well – 14-hour continuous high-load acid fracturing
National shale gas demonstration zones
Large-scale fracturing campaigns in North China – 7 wellsite industrial tests
Q5: What is the difference between the STP3300 and the SQP3300?
A: The STP3300 is a triplex (three-plunger) pump, while the SQP3300 is a quintuplex (five-plunger) pump developed later. The quintuplex design offers smoother flow output and was the world's first 11″ stroke quintuplex fracturing pump. Both are part of SJ’s comprehensive fracturing pump portfolio.
Q6: Can the STP3300 be customized for specific well conditions?
A: Absolutely. We customize plunger diameter, fluid end material, mounting configuration, drive type, and control systems to match your specific operational requirements.
Q7: What standards does the STP3300 meet?
A: The STP3300 is manufactured in accordance with API 674 / ANSI/HI Standards and SJ's API Q1, ISO 9001, and HSE certified quality systems.
Q8: What is the typical lead time for an STP3300?
A: Standard lead time is 90 to 180 days from order confirmation to shipment, depending on configuration and customization level. Contact our sales team for current availability.
Q9: Do you provide training and after-sales support?
A: Yes. Each STP3300 sale includes commissioning assistance and operator/maintainer training – either at your facility or ours. Spare parts are stocked for global shipment, and our technicians are available for field support.
Q10: How do I get a quote for an STP3300?
A: Send us your well parameters: target depth, expected pressure, required flow rate, preferred mounting configuration, and operating environment. We'll respond with a technical proposal and commercial quote within 7–10 business days.
