QWS 1000S Well Service Pump

The QWS 1000S is a versatile quintuplex pump featuring an efficient design that can be utilized in a back-to-back configuration.

Similar in design to the TWS 600S, the QWS 1000S offers a more powerful pump, capable of handling higher loads while still maintaining a compact design. Unique design features allow the QWS 1000S to be mounted in a back-to-back configuration on a single unit.

The QWS 1000S can be utilized in acidizing, cementing, gravel packing and snubbing operations.
