Frequently Asked Questions

A triplex pump uses three plungers while a quintuplex pump uses five. The additional plungers in a quintuplex deliver smoother flow, lower pressure pulsation and higher horsepower density, which makes quintuplex pumps well suited to high-rate fracturing. Triplex pumps remain the workhorse for cementing, acidizing and coiled tubing support.
Cementing typically uses triplex plunger pumps sized to your required pressure and flow rate. The correct choice depends on your working pressure, slurry rate, plunger size and power source. Share your operating parameters and our team will recommend a suitable model.
Yes. Fluid ends, fluid end parts, power end parts and expendables can be supplied together with the pump or as standalone replacement items. Provide the pump model, part number, drawing or a photo of the old part and we will match compatible parts.
Please provide the application, pump type and model, required pressure and flow rate, plunger size, fluid type, quantity and any documentation requirements. Drawings or photos help us confirm the exact configuration and respond faster.
