  • Rusty Resistance

Also, cast iron submersible pumps are quite easily rusty when used for a long time. When this situation occurs, water source may be polluted by rusty droppings, then our water qualification can not be guaranteed. And it is also bad for our health. For this occasion, APK chooses the material of stainless steel to cover our pumps submersible. For they are rusty resistance, the source of water or other medium we transfer is able to keep unpolluted, thus water quality can be greatly improved. So stainless steel submersible pumps are especially suitable for water quality required occasions, such as residential water supply.
