QWS 2500SD Well Service Pump

The QWS 2500SD is a rugged well service pump designed and manufactured to operate in harsh pumping conditions.

The QWS 2500SD is designed to withstand 10 hours of operation up to 6 days a week while maintaining a high performance rod load capacity that is necessary for harsh pumping conditions such as fracturing in the Barnett Shale.

Benefits of the QWS 2500SD:
1.24% greater wrist pin bearing surface area than the QWS 2500 Classic.
2. A more robust design featuring thicker performance plates than the QWS 2500 Classic.
3.A514 (T1) steel construction for maximum strength.
4.Fully interchangeable with the QWS 2500 Classic, with the same mounting and driveline positions.
5.Robust outer skins.
6.Fully-welded structural members.

QWS 2500SD Hydraulic Horsepower Curve

Note: This chart shows this pump’s performance at max hydraulic horsepower. Notice as the plunger size for the pump increases, a greater max flow rate is achieved while the max pressure decreases.
