High quality Water Tanks in various shapes - 500-650 litres 

A wide variety of industrial, commercial and domestic applications require particularly slim, flat, compact or round designs/shapes. Our water tanks from 500 litres are designed for the highest demands and loads. The rotationally moulded 500-650 litre water tanks are extremely robust, shock and impact resistant. The plastic used (polyethylene - MD-PE) is high quality, physiologically safe (food safe) and UV-stabilised. In the standard natural-translucent colour, the level is clearly visible from the outside. Other RAL colours are available on request. All water tanks with a capacity of 500 litres or more have a moulded-in 1" brass threaded outlet. The moulded baffles ensure excellent tank stability and provide baffle protection for mobile applications.

Water Tanks 500L - 650L with baffles

The majority of our water tanks from 500 litres upwards are manufactured with moulded baffles. In mobile use, these reduce sloshing of the water in the tank and also contribute to stability and optimised weight distribution.


Water Tanks 500L - 650L with moulded-in brass threaded BSP outlet

All 500L, 530L, 550L, 600L, 625L, 650L water tanks are supplied with an inch sized brass threaded BSP outlet moulded into the wall of the tank. These can be conveniently used as an outlet, connection or in-line connection. If this is not required, select the option Outlet: undrilled when ordering the water tank. The threaded BSP outlet will still be present on the Tank, but will be completely encased in plastic from the inside. The liquid in the tank will not get into contact with the brass threaded BSP outlet and the outlet is completely sealed. The threaded BSP outlet can be drilled/opened at any time if you still want to use it. We recommend using a hole circle drill/hole saw to remove the plastic coating on the inside of the threaded BSB outlet.
