IBO-GL-TW-125-40 wellhead
The IBO wellhead is a cover that hermetically closes 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 around 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 – watertight closure of the borehole and secure suspension of the pump on the metal eyelet.
- Submersible pump installers – routing the PE pipe and cable through a single sealed passage.
- Owners of domestic wells – protection of water intakes against surface contaminants.
- Service and maintenance teams – simplified access to the pump and 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 rope. The discharge pipe and power cable are routed through the head, while the entire assembly remains watertight thanks to compressed seals. A well closed in this way is protected from surface water, groundwater, and foreign bodies.
The watertight closure also 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 casing pipe diameter, PE pipe diameter, and cable thickness. The IBO TW/TZ wellhead is available in versions suited to 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 the conditions inside a well. The seal is an EPDM ring, while the screws, nuts, and eyelet for suspending the pump are made of galvanized steel. Each head has a cable gland ensuring a watertight passage for the power cable and a passage for the PE pipe sealed with a gasket.
The series differ in their installation method. The TW series head is fitted inside the casing pipe, while the TZ series head 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 eyelet allows a submersible pump weighing up to 200 kg to be suspended safely.

Frequently asked questions (FAQ) – what is the TW / TZ well head used for?
What is a well head used for?
The well head hermetically seals the casing pipe of a deep well and guides 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 well head is installed inside the casing pipe, while the TZ series well head is placed over the casing pipe from above. The TZ version also features a PE quick coupling and a screw-link for suspending the pump. The choice depends on how the casing pipe is finished in the well.
How do I choose the right well head size?
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, head diameter, and PE pipe diameter, respectively. If in doubt, please contact our technical department.
How do I install the well head?
The PE pipe is connected to the pump's discharge outlet and fed through the well head, while the cable is passed through the cable gland. The pump is suspended from a cable attached to the eye or link of the well head. The well head is then seated inside or on the casing pipe, and the screws are tightened. Installation should be carried out by a qualified installer with the power disconnected.
Is the well head 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 well head?
As a manufacturer, we do not sell directly. IBO TW and TZ series well heads are available from our trade partners, plumbing wholesalers, and authorized online distributors.
