The pantograph type is the most widely used seal design on external floating roof storage tanks.  It provides a long service life and is of a dynamic design that takes into consideration irregularities in the tank shell construction.

Overlapping compression plates push against a continuous wiper rim for a more flexible seal, to better compensate for tank shell irregularities and to provide a continuous vapour barrier membrane, for optimum sealing efficiency.

A cost effective double roof seal, utilizing compression plates backed with a vapour membrane,  that push against a continuous wiper seal.  Easily fitted to the roof rim plate either vertically or horizontally.

Utilizing rigid pipe arms, articulated with swivel joints and reinforced by a chain inbetween the arms.  We also offer a 'tri-lobe' design, with improved stability and minimum height.

Utilizing industrial grade rubber hose

(Nitrile or Viton®), this design offers a far more economical version of the expensive

'repeat lay pattern' type hose drains.

The most commonly manufactured design

 of articulated roof drain system.

 Utilizes flexible hose joints encased in

steel bracket plates.

Floating Suction Units are utilized In fuel

storage tanks for example, that require the product to be emptied from near the surface

to prevent sediment uptake.

Similar to a Floating Suction, a Floating Skimming Unit aims to skim off just the

surface level of the stored product, in the process of bio-fuel production for example.

Similar to a Floating Suction, a Floating Skimming Unit aims to skim off just the

surface level of the stored product, in the process of desalinization for example.
