Corrosion Resistant Sea Water Waterproof Stainless Steel deep well submersible pump:
Apk Submersible corrosion-resistant pumps are made of stainless steel (stainless steel 304/316/316L/duplex stainless/ss904L) and titanium. Because these materials are used, the pumps can handle chemical fluids of low pH value (e.g., corrosive acidic fluid), as well as seawater.
The corrosion-resistant pumps use highly corrosion-resistant materials for all parts that are exposed to fluids, including the impeller, casing, motor frame, outer cover, strainer stand, bend, flange and sealing parts.

Apk puts particular effort into developing submersible pumps made of stainless steel 304/316/316L/duplex stainless/ss904L stainless steel casting. In recent years, polluted water and runoff from mines and quarries have been cited as social problems in many countries, to the point that demand for pumps that can handle these fluids has been increasing year by year. In fact, more than 40% of the runoff from mines is strongly acidic with a pH value of less than 4. To meet this application, Apk has aggressively continued development of all stainless steel pumps that are made ofstainless steel 304/316/316L/duplex stainless/ss904L casting.
Because they are made of stainless steel casting, the pumps are resistant to wastewater containing abrasive substances, as well as corrosive fluids. That is, these pumps deliver the durability needed in harsh fields where pumps made of aluminium, stainless steel and cast iron suffer damage in a matter of weeks, if not days. More specifically, principal parts of the LH/LH-W-14 and SFQ series are made of stainless steel 304/316/316L/duplex stainless/ss904L casting, which considerably improves product reliability in comparison with stainless steel in applications involving heavy-duty work. Therefore, Apk stainless steel pumps can serve in harsh environments such as mines and quarries, as well as in chemical plants and wastewater treatment plants, thus covering a wide range of applications.
Furthermore, Apk offers seawater pumps that use titanium for parts exposed to fluids. The combination of resin and titanium enables a lightweight compact design that is the most suitable for handling seawater.
Apk continues its research so as to handle a variety of fluids.
