Frequently Asked Questions About HT400 Triplex Plunger Fracturing Pump

1. What is the HT400 triplex plunger fracturing pump used for?

The HT400 triplex plunger fracturing pump works in oilfield cementing, hydraulic fracturing, acidizing, well stimulation, pressure testing, and high-pressure fluid injection. Oilfield service companies often use it as the main pump in compact cementing units, fracturing skids, acidizing equipment, and mobile well service packages. Its 400 BHP power rating, compact structure, and stable reciprocating design make it suitable for demanding oil and gas wellsite operations.

2. What power rating does the HT400 oilfield triplex pump provide?

The HT400 provides a maximum brake horsepower of 400 BHP / 298 kW. This power level suits medium and high-pressure oilfield applications where equipment builders need compact layout, reliable output, and controlled fluid delivery.

3. What are the main components of the HT400 triplex plunger pump?

The HT400 includes the power end, gearbox, and fluid end. The power end supports stable mechanical movement, the gearbox transfers input power, and the fluid end handles high-pressure fluid delivery. This clear structure helps service teams inspect, maintain, and replace key parts more efficiently.

4. Can the HT400 work as an oilfield cementing pump?

Yes. The HT400 works well as an oilfield cementing pump for primary cementing, squeeze cementing, remedial cementing, and other cement slurry pumping operations. It helps deliver slurry into the wellbore with controlled pressure and flow. Its compact body also fits truck-mounted cementing units and skid-mounted cementing packages.

5. Is the HT400 suitable for hydraulic fracturing equipment?

Yes. The HT400 supports hydraulic fracturing equipment that requires stable pressure generation and continuous fluid delivery. Its 180,000 lbs / 800 kN maximum connecting rod load helps the pump handle demanding pressure jobs. Equipment manufacturers can use it in compact fracturing packages, stimulation units, and mobile pressure systems for oil and gas wells.

6. Can the HT400 pump handle acidizing and formation treatment service?

The HT400 can work in acidizing units for wellbore cleaning, carbonate formation treatment, scale removal, and production stimulation. For acidizing service, customers should choose suitable fluid end materials, seals, and wetted components according to acid type, concentration, temperature, and pressure. Proper selection helps improve service life and supports safer field operation.

7. What fluid end sizes does SGPE offer for the HT400 pump?

PREMIUM supplies HT400 fluid ends in 4 in and 4.5 in specifications. Customers can choose the right size according to pressure, flow rate, pumped medium, and job type. These options help match different cementing, fracturing, acidizing, stimulation, and pressure testing requirements.

8. What material does the HT400 fluid end use?

The HT400 fluid end uses 4330V material. This material supports strength, durability, and stable performance in high-pressure oilfield applications. A reliable fluid end matters because it handles repeated pressure cycles, treatment fluids, cement slurry, and other demanding well service media.

9. How should I choose between 4 in and 4.5 in HT400 fluid ends?

Customers should choose between 4 in and 4.5 in fluid ends based on pressure, flow rate, pumped medium, equipment layout, and field application. A smaller fluid end may suit higher-pressure needs, while a larger size may support higher flow under suitable conditions. You can send PREMIUM your operating pressure, required displacement, fluid type, and installation layout for configuration support.

10. What makes the HT400 suitable for truck-mounted and skid-mounted units?

The HT400 combines compact dimensions, 400 BHP power, and strong pressure capability. These features help equipment manufacturers save space on truck-mounted cementing units, skid-mounted acidizing systems, mobile fracturing packages, and trailer-mounted well service equipment. Its three-section structure also supports easier field maintenance.

11. Can SGPE supply HT400 replacement fluid ends and pump parts?

Yes. PREMIUM can supply HT400 fluid ends and related replacement parts for oilfield service fleets, equipment manufacturers, and spare parts distributors. Customers can send the pump model, fluid end size, material requirement, working condition, and quantity for quotation. This support helps reduce procurement complexity and keeps service equipment ready for operation.

12. What information should I provide when requesting a quotation for the HT400 pump?

Please provide the pump model, application, working pressure, required flow rate, fluid end size, pumped medium, drive type, installation method, quantity, and destination. You can also tell PREMIUM whether the pump will work in a cementing truck, fracturing skid, acidizing unit, pressure testing system, or stimulation package. Clear operating data helps PREMIUM recommend a suitable HT400 pump configuration and prepare a more accurate quotation.

Description

The HT-400™ positive displacement triplex pump was originally designed for hydraulic
fracturing service as a high-pressure slurry pump. Since the HT-400™ pump’s original
development, it has been utilized for a variety of duties inside and outside the oil and gas
service industry.
Some of the features that separate the HT-400™ pump from other pumps include:
• Can pump at pressures as high as 20,000 psi (137.895 MPa) (depending on the fluid end
size).
• Has a long working history of dependability, high performance, durability, and long life.
• Its compact design allows for ease of mounting and transporting.
