WMA ISO 13709/API 610 (OH4) Rigidly Coupled, Vertical In-line, Low-Flow, High-Head Process Pump
The WMA is a rigidly coupled, ISO 13709/API 610 OH4 design vertical in-line pump and features the same hydraulics as the HWMA. The WMA uses a P-base motor and is shorter in height than the ISO 13709/API 610 OH3 design of the HWMA.

Replaceable Volute Insert permits precise hydraulic customization. Each insert is engineered for specified head and flow requirements. Accommodates future system changes.
Rigid Coupling ensures precision shaft alignment while eliminating time-consuming manual alignment.
Casing and Cover feature metal-to-metal fits with fully confined, controlled compression gasket to ensure proper sealing and alignment.
Raised Face Flanges are to ASME B16.5, Class 300 for one stage and Class 600 for two-stage models.
ISO 21049/API 682 Seal Chamber accommodates a wide variety of seal configurations including dual pressurized and unpressurized cartridge types for the most severe services.
Stiff Shaft Design limits deflection at seal faces to 0.05 mm (0.002 in) max. Vibration levels are well below that required by ISO 13709/API 610.
- Flows to 45 m3/h (200 gpm)
- Heads to 220 m (725 ft)
- Pressures to 50 bar (750 psi)
- Temperatures to 260°C (525°F)

Flowserve HWMA Pumps - Low-Flow, High-Head, Vertical In-line Process Pump With Bearing Housing - ISO 13709/API 610 (OH3) - HWMA2, WMA and WMA2 models included.
|Description:||Flowserve’s HWMA is a two stage, vertical in-line overhung pump with a separate bearing bracket. With its small footprint, this low flow, high head process pump is a space-saving alternative to many overhung process pumps in upstream and downstream services.|
|Description:||The WMA2 is a two stage rigidly coupled pump designed to comply with API requirements for OH4 pumps. Like the HWMA2 pump, the high head hydraulics of the WMA2 are achieved using back-to-back, radial blade impellers and 2-pole P-base motors without high speed gear boxes.|
|Description:||The HWMA is a single stage, vertical in-line overhung pump with a separate bearing bracket. With its small footprint, this low flow, high head process pump is a space-saving alternative to many overhung process pumps in upstream and downstream services.|
