At Tankworld we take our quality standards pretty seriously, so when we supply a pump with a Tankworld Tank we expect it meets not only our high standards but Australian Standards as well.
White International, manufacturers of BIANCO and DAB Pumps, have a range of pumps that have been AS/NZS4020 Drinking Water Approved, offering peace-of-mind when you buy their products.
This approval ensures the pump will not contribute any toxic materials or metals to the liquid being pumped, won’t support the growth of micro-organisms and won’t change the taste or appearance of your water.

Below is an extract from white international covering what is involved in the standard and what it tests for. For more information about this, please click here to visit white international.
What is The Standard:
Appearance of Water Extract:
Water that has been in contact with a product is examined for any increase in colour or turbidity.
Growth of Aquatic Micro-organisms:
In a test spanning 8 weeks, products are examined for the ability to support bacterial growth by monitoring dissolved oxygen levels.
Mutagenic Activity of Water Extract:
An AMES test is used to determine whether products release mutagenic compounds. Water extracts are mixed with specific bacteria. Any measured change in genetic nature of the bacteria is regarded as evidence of mutagenic activity.
(A mutagenic agent can induce or increase the frequency of mutation in an organism.)
Cytotoxic Activity of Water Extract:
Water extracts are tested for cytotoxicity using mammalian cell lines maintained in laboratory culture. Any adverse effect on the health of the cells is recorded as a cytotoxic effect. (Cytotoxicity is the quality of being toxic to cells)
Extraction of Metals:
Water extracts are examined for the release of Arsenic, Antimony, Barium, Cadmium, Chromium, Copper, Lead, Mercury, Molybdenum, Nickel, Selenium and Silver. The limits are in line with Australian Drinking Water Guidelines (ADWG). The extraction procedure is either by end-of-line test or in-line test.
High Temperature Tests:
