Brand: IDP
Description:

The Flowserve WM2 is a two-stage, close-coupled vertical in-line pump designed in accordance with ISO 13709 / API 610 (OH5) standards. Engineered for low-flow, high-head services, the WM2 pump features a compact design that eliminates the need for a separate bearing housing. Its modular construction allows for over 100 Best Efficiency Point (BEP) fits within a single pump size, ensuring optimal performance across various applications. The WM2 is ideal for industries such as oil and gas, petrochemical processing, and high-temperature services, where space-saving and reliable operation are critical.

The Flowserve WM2 is the space-saving, close coupled configuration of the HWM2 pump. This two-stage pump is designed specifically for low flow, medium to high head operation and is fully compliant with API 610 (OH5), latest edition.
