Frequently Asked Questions

What is the difference between triplex and quintuplex pumps?

Triplex pumps have three plungers and are simpler in design. Quintuplex pumps have five plungers, offering smoother flow, reduced pulsation, and longer seal life due to lower peak pressures.

Can your pumps handle seawater or brine?

Yes, we offer pumps with stainless steel or corrosion-resistant coatings suitable for seawater, brine, and high-TDS fluids commonly used in water flooding.

Do you provide skid-mounted or turnkey systems?

Yes, we manufacture complete skid-mounted units with motors, drives, controls, and piping, ready for quick installation and commissioning.

What maintenance is required for plunger pumps?

Regular inspection of seals, valves, and lubrication systems is recommended. We provide maintenance schedules and spare parts kits for all models.
