OEM & Special Duty
Original Equipment Manufacturers (OEM’s) are very important for Flowserve FSD. Therefore Flowserve is committed to develop and supply designs for special equipment and for special duty requirements.
PSS III
| Brand | Flowserve |
|---|---|
| Description | Split, single semi-cartridge pusher seal for pumps and mixers in non-hazardous applications. |
- Applications:
Chemical Processing, Power Generation, Chemical Transfer, Mineral Processing, Pulp and Paper - Industries:
Paper Stock
The ultimate semi-cartridge split seal for pumps and mixer applications. The four piece unitized design allows for one person installation capability. All components are self contained eliminating equipment measurements small parts handling and the potential for lost parts. The improved design makes installation easy while capable of high pressure operation. The PSS III is ideally suited for pulp and paper, general chemical, wastewater treatment, municipal water, power generation and mineral and ore processing industries.
GW / BAW
| Brand | Flowserve |
|---|---|
| Description | Standard pusher for integrally geared API pumps and compressors |
Standard conventional liquid mechanical seals used in integrally geared API pumps and compressors including high speed and high pressure services.
PSS II
| Brand | Flowserve |
|---|---|
| Description | Split seal |
- Industries:
Waste Processing, Plating, Galvanizing and Other Coatings, Polymers, Water Supply and Distribution, Descaling, Primary Processing, Water Treatment, Dewatering & Water Supply, Scale Recycle, Slurry Transfer, Digester, Acid Transfer, Electronics, Agriculture, Fire Protection – General Industry, Automotive and Aircraft, Flood Control, Auxiliary, Food Processing, Bleach Chemicals, Ground Water Development and Irrigation, Boiler Feed, HVACI, Caustic and Chlor-Alkali, Hydraulic Press, Slurry Processing, Chemical and Liquor, Leaching Acid, Wastewater Collection and Treatment, Coatings, OEM, Snowmaking, Construction, Paper Stock, Solvents, Cooling Water – Metals, Pharmaceuticals, Volatile Organic Compounds, Cryogenic, Desalination
A split seal with only two components simplifies seal installation without requiring equipment teardown. Semi-cartridge rotating and stationary assemblies eliminate equipment measurements and handling of small components including seal faces and gaskets. The PSS II is suited for general chemical industry, pulp and paper, wastewater treatment, power generation, and mining services.

DHTW / UHTW OEM & Special Duty Seal
| Brand | Flowserve |
|---|---|
| Description | Designed for the Power Industry, the DHTW seal has the ability to survive low or lost suction conditions for short time frames. |
- Applications:
Boiler Feed - Industries:
Water Handling and Treatment, Utilities, Boiler Circulation Systems, Crude Handling and Treatment, Crude Pipeline, Delayed Coking, Distillation, Hydrocraking, Hydrotreating, Alkylation, Logistics and Tank Farm, Water Injection, Miscellaneous Services, Products Pipeline, Boiler Feedwater Systems, SAGD, Heavy Oil and Upgrading, Catalytic Cracking, Steam Systems, Condensate Systems, Cooling Systems
Balanced, stationary multi-spring seal, designed for power industry or other high pressure/high speed applications. Using an API Plan 23 system, this seal is used in hot applications. This seal is always carefully analyzed and tuned for balance and low face deformation for critical applications. Today’s power generation plants are increasing the need for higher parameter mechanical seals for boiler feed and boiler circulating pumps. Flowserve’s DHTW has “hot standby” capability and the ability to survive low or lost suction conditions for short time frames which are important requirements in the power industry.
UHTW As DHTW, without pumping device.
