The double case APKD features an innovative, double suction impeller in a true twin-volute design that produces more flow and higher head at lower NPSHR and can operate at higher speeds than conventional vertical turbine pump models.

The VPC vertical turbine, double casing pump is a diffuser type, single or multistage design for services with limited NPSH available.

Compliant with ISO 13709/API 610 (VS6), the Flowserve WUC vertical turbine is a radial flow or axial flow type, multistage, heavy-duty double casing pump. It is designed for continuous un-spared duty at a variety of high-pressure services, operating at temperature extremes and handling difficult liquids.

The QLC and QLQC are double-casing, double-suction, vertical turbine pumps. Available in single or multistage units and featuring true twin-volutes, QLC and QLQC pumps incorporate the proven hydraulics of the QL and QLQ into a double-casing configuration. Design flexibility makes these pumps ideal for process applications. Standard and ISO 13709/API 610 (VS7) compliant designs are available to meet varying industry demands. For the power industry, the standard pump design offers the advantage of multistage construction for reliable condensate extraction service.
