Seawater High Pressure Pump
Product Description
Pressure: 1200 p.s.i. (85 kgf/cm2) | Suction Volume: 178 Liter/Minute
Product Introduction
WH-12170 Duplex Stainless Steel Seawater Plunger Pump
The WH-12170 is a high-flow industrial grade seawater plunger pump engineered for demanding marine, offshore, and desalination applications. It is designed with SUS2205 duplex stainless steel fluid-end components to ensure superior resistance to seawater corrosion, chloride attack, and harsh operating environments.
- Maximum Pressure: 85 Bar / 1200 PSI
- Flow Capacity: 178 L/min (High Flow Design)
- Operating Speed: 750 RPM (Low-Speed Long-Life Design)
- SUS2205 Duplex Stainless Steel Fluid-End
- Continuous Duty Industrial Operation
Compared with conventional high-speed pump designs, the WH-12170 operates at a reduced 750 RPM, significantly improving mechanical stability, reducing wear, and extending service life in continuous seawater and offshore applications.

Why Low RPM Design Improves Reliability
The WH-12170 is engineered with a 750 RPM low-speed operating system, which significantly reduces internal mechanical stress compared to standard high-speed plunger pumps.
Lower rotational speed improves bearing life, reduces heat generation, minimizes vibration, and enhances overall system stability. This makes the WH-12170 particularly suitable for continuous-duty seawater and offshore applications where reliability is critical.
Combined with SUS2205 duplex stainless steel construction, the low RPM design ensures long service life and reduced maintenance requirements in harsh industrial environments.
