General warning:
General note for products which may be used for seawater:
Although our products can be used in seawater systems it should always be noted that, in case of
installation in a piping system made of materials which are frequently used because of their excellent
seawater resistance (e.g. Cunifer), large potential differences may occur possibly causing corrosion
which could permanently damage the proper functioning and integrity of our product.
A combination of different materials should always be mentioned prior to the purchase of our products
in order for us to give the best possible advise on a safe functioning.
General note for cast iron products:
Cast iron can be used for various applications, such as listed in our catalogue. It should however
always be observed, that frost (in combination with non-drained products) may permanently damage
the proper functioning and integrity of our product.
