Our Stainless Steel pumps are made from 304 Grade stainless steel. This helps prevent rusting and is a high quality material.
The internal pump is made from plastic which is the same as all pumps on the market. This is to prevent reactions with metal content ad fluids causing pumps to not work over time and increase the cost and overall weight of the product.
No harmfull materials or plastics are used. Please see a breakdown of materials used in our pumps.
