ASSEMBLY AS A SLEEVE PAM Rapid Couplings (S and INOX)

DN 50 to 200

Couplings are supplied pre-assembled. The PAM Rapid from DN 50 to 200 is designed to be tightened to fully closed, there is no need to check the torque.

  1. Push the supplied assembled coupling onto the pipe spigot so that it abuts on the central register of the elastomer gasket.
  2. Push the next pipe spigot into the other end of the coupling.
  3. Tighten the screw to “zero gap” position, i.e. fully closed, with a ratchet spanner or electric screwdriver.

 

DN 250 to 300

They can be assembled in two different ways, depending on whether an open strap is required.

They can be assembled in two different ways, depending on whether an open strap is required.

Standard assembly

  1. Open the stainless steel strap.
  2. Slide the stainless steel strap loose around the first pipe component.
  3. Push the sealing gasket onto the component spigot so it abuts on the central register of the gasket.
  4. Push the second component into the sealing gasket, so that it abuts on the central register.
  5. Bring the steel strap over the sealing gasket.
  6. Tighten the bolt with a ratchet spanner or a power tool applying the following tightening torque: DN 250 and DN 300 = 25 N.m.

Open strap assembly

OPEN BELT ASSEMBLY

An open strap is sometimes required to facilitate access: stack installation, etc.

  1. Push the rubber gaskets onto the spigot ends top and bottom, ensuring the central registers are abutted against each spigot edge.
  2. Twist the stainless steel strap to ease the wrapping around the pipe components.
  3. Clip the bolt and loosely assemble the coupling around the gasket.
  4. Check the alignment of the assembly before tightening the bolt with a ratchet spanner or a power tool, applying the following tightening torque: DN 250 and DN 300 = 25 N.m.

Attention! Wherever couplings may be subject to end thrust forces, they must be secured with grip collars.
