160 / 40 mm Through-Wellhead Made of Plastic
A through-wellhead is a metal cover that hermetically seals the casing pipe of a deep well and carries the pump discharge pipe through it. The PE pipe passes through the wellhead, where it is clamped by a seal. A separate cable gland ensures a watertight passage for the power cable. Thanks to the seal on the casing pipe, the well remains protected against surface water and contaminants.
Who is it for?
-
Well drillers and drilling companies – watertight sealing of the borehole and secure suspension of the pump from the metal eye.
-
Deep-well pump installers – the PE pipe and power cable pass through one sealed penetration.
-
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 through-wellhead is used to close the casing pipes of deep wells containing a pump suspended on a cable. The PE discharge pipe exits through the wellhead, while the power cable passes through a cable gland – the entire assembly remains watertight thanks to the clamped seals. A well closed in this way is protected against surface water, groundwater, and foreign bodies.
The hermetic seal also allows better use of the capacity of shallower wells – a vacuum may form between the wellhead and the pump, supporting water intake as the water level falls. The variant is selected according to the casing pipe diameter and the PE pipe diameter. The IBO through-wellhead is available in versions suitable for 110, 125, and 160 mm casing pipes.
Features of the through-wellhead
The through-wellhead is made of metal – steel or galvanized cast iron – resistant to the conditions inside the well. The PE discharge pipe passes through the body and is secured by a clamped seal, which also seals the passage. A second seal is tightened around the casing pipe, closing the well.
The cable supplying power to the pump is routed through a cable gland, ensuring watertightness at the cable penetration as well. A metal eye is provided for suspending the pump, with the support cable attached to it. The variant is selected according to the casing pipe diameter and the diameter of the outgoing PE pipe.

Frequently Asked Questions (FAQ) – IBO Through-Wellhead
What is a through-wellhead used for?
The through-wellhead hermetically seals the casing pipe of a deep well and carries the PE discharge pipe and pump cable through it. It protects the well against surface water, groundwater, and contaminants. The metal eye allows the pump to be safely suspended from a cable.
How does a through-wellhead differ from a version with an external thread?
In a through-wellhead, the PE pipe passes through the body and is clamped with a seal, so it forms one continuous line. In the version with an external thread, the discharge pipe is connected to the thread on the wellhead. The choice depends on how the discharge pipe is routed in the installation.
How do you choose the wellhead size for a well?
Two parameters must be matched: the diameter of the well casing pipe (110, 125, or 160 mm) and the diameter of the PE pipe leading to the pump (from 25 to 63 mm, depending on the variant). Diameters of 110–125 mm correspond to 4" wells, while 160 mm corresponds to 6" wells. If in doubt, consult the technical department regarding the selection.
How do you install a through-wellhead?
The PE pipe is connected to the pump's discharge outlet, passed through the wellhead, and clamped with a seal, while the cable is routed through the cable gland. The pump is suspended from a cable attached to the wellhead eye, after which the wellhead is seated in the casing pipe and the seal is tightened. Installation should be carried out by a qualified installer with the power disconnected.
Can a deep-well pump be suspended from the wellhead?
Yes. Each wellhead has a metal eye to which a support cable is attached to hold the pump in the casing pipe. The cable bears the weight of the pump, so the discharge pipe and cable are not strained.
Where can an IBO wellhead be purchased?
As the manufacturer, we do not sell directly. IBO through-wellheads can be purchased from our trade partners, plumbing and installation wholesalers, and authorized online distributors. The variant is selected according to the diameter of the casing pipe and PE pipe.
What is the warranty on an IBO wellhead?
IBO – 24 months (2 years) of the manufacturer's warranty. Warranty and post-warranty service is provided by Dambat. For questions about selecting the variant, please contact an authorized distributor.
