Seawater Centrifugal Pump

WUZ

Product code: WUZ

Application

Seawater
Seawater intake and circulation
Drainage of aquaculture farm, fishery processing factory and others.

Feature

Starting/stopping water levels are adjustable in L and LN types.
Uses titanium for the metal part contacting water, and plastic in the pump to achieve corrosion proof, light weight and easy-to-handle features.
Glass fiber reinforced plastic is used in plastic parts which require strength, such as the impeller and casing.
As well as excellent performance to pass foreign objects because of vortex type, furthermore, high water pumping performance.
Motor has built in auto-cut which prevents from burnout.
Semi-open impeller prevents foreign objects from clogging. Strainers are quick detachable type for easy maintenance. (0.75kW or less)
Double mechanical seal prevents water immersion into motor.
