Features of HT400 Triplex Plunger Pump
600 BHP High-Power Drive System
HT400 Triplex Plunger Pump features a 600 BHP (447 kW) power end with an 8.6:1 gear ratio, delivering stable high-pressure output under heavy-load conditions for long-duration fracturing and injection operations.
Stable Triplex Pressurization Structure
Adopts a triplex alternating discharge system, reducing pressure fluctuation by 15%–20% and maintaining stable output at up to 20,000 psi, minimizing pipeline impact.
High-Wear-Resistance Plunger System
Uses ceramic or amorphous alloy-coated plungers, increasing wear resistance by around 100% and enabling continuous operation beyond 8,000 hours.
Modular Maintenance Structure
Separates power end, gearbox, and fluid end, allowing independent replacement of key components and reducing maintenance time by approximately 30%.
