WA.GP.B

WA.GP-B models are designed for pipe sealing outside the wall. They seal against the wall and around the pipe. WA.GP-B seals are available for most pipe sizes.

External Wall Mount Seals are used when a pipe penetration needs to be sealed from outside the wall. When too small a core opening exist, the pipe is non axial, or an out of round condition exist.

WA.GP-B model disk-seals are available in a two piece split version for existing pipes, or one piece units.


WA.GP-B disk seals are only 60 mm thick, allowing installations in restricted spaces.

 

They are simple to install with a very high clamp force ring, providing a 36 psi seal.

Maximum corrosion protection Stainless steel plates and elastomers of EDPM, NBR or Silicone elements are available.


External wall mount sleeves
Thimble Sleeves for Pipe Sealing

WA.GP-T Thimble wall sleeves, pipe sleeves and seals for multiple or single pipe penetrations. Thimble sleeves are bolt fastened on an exterior concrete wall, or floor. Back platesl may be flat or curved.

Thimble sleeve assemblies may be used for metal tank pipe penetrations. Plates are welding or bolting to the tank wall.

Use Split stainless steel wall sleeves, for pipes/cables that are already in place The pipe seals may be modular seals or disk compression seals.

 

external-wall-mount-split-sleeve-pipe-seal

GP-T pipe seals are designed for watertight sealing of conduit and cables passing through construction walls or concrete tanks and hydraulic structures. The assembly combines a sleeve which is fasten to the wall and modular seals or disk compression seals. 

Split sleeves with seals for multi pipe penetrations through the same sleeve are available.

Models WA.GP-UM Eccentric disk-seals , seal off center pipes.

Eccentric seals are also used in pipe/casing installations for sealing pipe through casing when the carrier pipe is not in the centered position.

WA.GP-UM Split Eccentric pipe seals for existing pipe.

pipe-not-centered-sealing

Non axis pipe sealing type GP - UM eccentric seals, provide 2.5 bar, 36 psi seals for the piping systems. They are available in a split or single configurations.

UM seals are used in pipe through casing applications where the pipe placement is below or above the center line.

It is not necessary to do extensive reconstructive repairs to a non-centered pipe penetration, eccentric pipe seals may be used for a watertight solution for the existing placement.


pipe-off-center-in-hole

For gravity feed systems it may be necessary to increase the casing size for a correct grade line. As long as the minimum annular space, is more than 25 mm - an eccentric pipe seal can be used.


 

When ordering a not centered existing pipe seal, it is necessary to measure the displacement (eccentricity) in 12 point locations; as shown in figure above, to insure the correct seal is ordered.

How to measure the distances for a Eccentric Pipe condition.

Dimensions (inches or mm)

  • Outer Diameter of carrier pipe:
  • Inner Diameter of hole (if it is circular shaped) not deformed.
  • Measures according to the drawing above, the measure points are relative to the pipe not the opening.
  • Divide the carrier pipe (not the hole) into 12 equal pieces. At the starting point 12 measure clockwise at each point out to the hole ID.
  • A photograph of the penetration as it exist, in conjunction with the A-B measures.
  • Additional information: Notes*

If a waterproofing membrane or containment liner is installed, type GP-F compression seals should be used for water tight sealing. Type GP F disk seals, seal the pipe and the liner.

WA.GP-F models are used in applications for lining a Vault, waste disposal containment liners, tank secondary liners, hazardous waste containment, foundation wall liners etc.

A WA.GP-LR Disk-seal has one of the compression disk slightly larger, it acts as a lip clamp ring. They are designed for use in applications where water hammer is expected along a pipeline.

The enlarged ring is installed on the inflow side and absorbs the excess pressure that may occur along the pipe.
