IBO-GL-TW-110-32 wellhead
The IBO wellhead is a cover that hermetically seals the casing pipe of a deep well and routes the discharge pipe and the pump’s power cable through it. Thanks to the gasket clamped onto the casing pipe, it protects the well against the ingress of contaminants and surface water. The series includes two installation variants—TW and TZ—in several sizes suited to typical well installations.
Who is it for?
- Well drillers and drilling companies – tightly closing the borehole and securely suspending the pump from the metal eye.
- Submersible pump installers – routing the PE pipe and cable through a single sealed passage.
- Owners of private wells – protecting water intakes from surface contaminants.
- Service and maintenance teams – simplifying access to the pump and enabling periodic inspection of the well installation.
Applications
The TW wellhead is used to close the casing pipes of deep wells in which a pump is suspended on a cable. The discharge pipe exits through the head, and the power cable is also routed through it, while the entire assembly remains sealed by compression gaskets. A well closed in this way is protected against surface water, groundwater, and foreign bodies.
The tight closure allows the capacity of shallower wells to be used more effectively—the space between the head and the pump may develop a vacuum that assists water intake as the water level falls. The specific variant depends on the diameter of the casing pipe, the diameter of the PE pipe, and the cable thickness. The IBO TW/TZ wellhead is available in versions compatible with 110 and 125 mm casing pipes.
Features of the TW wellhead series
The body, base, and head cover are made of glass-fiber-reinforced polyamide (PA6+30GF), a material resistant to loads and conditions in the well. The seal is an EPDM ring, while the screws, nuts, and eye for suspending the pump are made of galvanized steel. Each head has a cable gland ensuring a watertight passage for the power cable, as well as a passage for the PE pipe sealed with a gasket.
The series differ in their installation method. The head of the TW series is fitted inside the casing pipe, while the head of the TZ series is placed over the casing pipe from above; the TZ version is additionally equipped with a PE quick connector and a threaded link for suspending the pump. Regardless of the variant, the metal eye allows you to safely suspend a submersible pump weighing up to 200 kg.

Frequently asked questions (FAQ) – what is the TW / TZ wellhead used for?
What is a wellhead used for?
The wellhead hermetically seals the casing pipe of a deep well and routes the discharge pipe and pump cable through it. It protects the well against surface water, groundwater, and contaminants, while the metal eye allows the pump, weighing up to 200 kg, to be safely suspended.
What is the difference between the TW and TZ series?
The TW series wellhead is installed inside the casing pipe, while the TZ series wellhead is fitted over the casing pipe from above. The TZ version additionally features a PE quick connector and a bolted link for suspending the pump. The choice depends on how the casing pipe is terminated in the well.
How do I choose the right wellhead size for my well?
Three parameters must be matched: the casing pipe diameter (110 or 125 mm), the diameter of the PE pipe leading to the pump (25, 32, 40, or 50 mm), and the power cable diameter (6–10 mm in the TW series, 6–12 mm in the TZ series). The model designation, e.g. IBO-GL-TW-125-40, indicates the series, wellhead diameter, and PE pipe diameter, respectively. If you have any questions, please contact our technical department.
How do I install a wellhead?
The PE pipe is connected to the pump’s discharge outlet, passed through the wellhead, and the cable is fed through the cable gland. The pump is suspended from a rope attached to the wellhead’s eye or link, after which the wellhead is seated in or on the casing pipe and the screws are tightened. Installation should be performed by a qualified installer with the power disconnected.
Is the wellhead covered by the manufacturer’s warranty?
IBO – 24-month (2-year) manufacturer’s warranty. Dambat provides warranty and post-warranty service.
Where can I buy an IBO TW / TZ wellhead?
As a manufacturer, we do not sell directly. IBO TW and TZ series wellheads are available from our trade partners, plumbing wholesalers, and authorized online distributors.
