Seawater Centrifugal Pump

GSP

Product code: GSP

Application

Seawater intake and circulation
Circulation of aquaculture farm, fishery processing factory, and aquaculture pond.
A variety of seawater supply

Feature

High versatility. Flanged connection (equivalent to JIS 10K) on the discharge side makes piping work smooth, and installation and replacement easy. Pump and motor are mono-block construction, and compact and light weight. Outdoor installation is possible
Excellent suction lift up performance. Self-priming with high suction lift up performance does not require foot valve and makes priming works easier. High lifting performance is realized with high efficiency design.
High durability. METTON? witch has high resistance to chemical and climate material is used for casing, and hardness also improve. Outdoor installation become to be available. Polyester powder is used for coating base. Gained much further rust resis
