Metal Wellhead 125 for Swedish Coupling
The IBO 125 wellhead for a Swedish coupling is a metal cover that hermetically seals the casing pipe of a deep well. Its outlet is designed for connecting the discharge pipe using a Swedish coupling. The power cable for the pump passes through a separate cable gland, while the seal on the casing pipe protects the well against surface water and contaminants.
Who it is for
-
Well drillers and drilling companies – tight sealing of the borehole and secure suspension of the pump from the metal eye.
-
Deep-well pump installers – the Swedish coupling enables quick and reliable connection of the discharge pipe.
-
Owners of domestic wells – protection of the water intake against surface contaminants.
-
Service teams – organized access to the pump and periodic inspection of the well installation.
Application
The wellhead for a Swedish coupling is used to seal the casing pipes of deep wells in which a pump suspended on a rope operates. The discharge pipe is connected to the wellhead using a Swedish coupling, while the power cable passes through a cable gland – the entire assembly remains sealed thanks to the compressed gasket. A well sealed in this way is protected against surface water, groundwater, and foreign objects.
This type of outlet is suitable for installations in which the discharge pipe is connected with a screw-on Swedish coupling. The version depends on the diameter of the well casing pipe. The IBO wellhead for a Swedish coupling is available in versions suited to 110, 125, and 160 mm casing pipes.
Features of the wellhead for a Swedish coupling
The wellhead is made of metal – steel or galvanized cast iron – resistant to the conditions inside the well. The discharge outlet is designed for a screw-on Swedish coupling, which connects the discharge pipe. The gasket is compressed against the casing pipe, sealing the well.
A special opening for routing the power cable ensures a tight seal also at the cable passage. A metal eye is provided for suspending the pump, with the support rope attached to it. The version is selected according to the diameter of the well casing pipe.

Frequently asked questions (FAQ) – IBO wellhead for a Swedish coupling
What is a wellhead for a Swedish coupling used for?
A wellhead for a Swedish coupling hermetically seals the casing pipe of a deep well, while the discharge pipe is connected to it with a screw-on Swedish coupling. It protects the well against surface water, groundwater, and contaminants. The metal eye allows the pump to be safely suspended on a rope.
How does a wellhead for a Swedish coupling differ from a pass-through model and one with an external thread?
In this version, the discharge pipe is connected with a screw-on Swedish coupling. In the pass-through version, the PE pipe passes through the body and is clamped with a gasket, while in the version with an external thread, the pipe is screwed onto the thread on the wellhead. The choice depends on how the discharge pipe is connected in the installation.
How do I choose the size of a wellhead for a Swedish coupling?
The size is selected according to the diameter of the well casing pipe – versions of 110, 125, and 160 mm are available. Diameters of 110–125 mm correspond to 4" wells, while 160 mm corresponds to 6" wells. The Swedish coupling is then selected according to the diameter of the discharge pipe.
How do I install a wellhead for a Swedish coupling?
Connect the pump’s discharge pipe to the wellhead outlet using a Swedish coupling, and pass the cable through the cable gland. Suspend the pump from a rope attached to the wellhead eye, then seat the wellhead in the casing pipe and compress the gasket. Installation should be performed by a qualified installer with the power disconnected.
Can a deep-well pump be suspended from the wellhead?
Yes. The wellhead has a metal eye to which the support rope holding the pump in the casing pipe is attached. The rope bears the weight of the pump, so the discharge pipe and cable are not subjected to the load.
Where can I buy an IBO wellhead?
As the manufacturer, we do not sell directly. IBO wellheads for Swedish couplings can be purchased from our trade partners, installation wholesalers, and authorized online distributors. The version is selected according to the diameter of the casing pipe.
What is the warranty on an IBO wellhead?
IBO – 24 months (2 years) manufacturer’s warranty. Warranty and post-warranty service is provided by Dambat. For questions about selecting the appropriate version, please contact an authorized distributor.
