In 1943, in an era of medical underdevelopment, the relatives of our founder Mr. Huang Hsiu Hsiung passed away after contracting cholera from contaminated water. For this reason, relying on the thoughts of loved ones, Mr. Huang Hsiu Hsiung embraced the provision of a convenient and high-quality water supply as a lifelong vocation. Mr. Huang Hsiu Hsiung hoped to become like a walrus, living in severe climates, possessing the spirit to challenge limits and never give up, and overcoming all difficulties. Being able to imitate the spirit of the walrus to acquire the power to rule the seas and become the leader in water pumps has become our goal. For this reason, we decided to reposition the old company to be ready to challenge global markets and shape the Walrus brand according to the spirit of the walrus! As the walrus rides the wind and waves, we will forge ahead bravely and actively expand!
