IBO-GL-TW-125-32 well head
The IBO well head is a cover that hermetically seals the casing pipe of a deep well and routes the discharge pipe and the pump 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 from the metal eye.
- Submersible pump installers – routing the PE pipe and cable through a single sealed pass-through.
- Owners of domestic wells – protecting water intakes from surface contamination.
- Service and maintenance teams – simplifying access to the pump and enabling periodic inspection of the well installation.
Applications
The TW well head 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 compression gaskets. A well closed in this way is protected from surface water, groundwater, and foreign objects.
The watertight closure also allows better use of the capacity of shallower wells: a vacuum may form between the head and the pump, supporting water intake as the water table drops. The specific variant depends on the casing pipe diameter, PE pipe diameter, and cable thickness. The IBO TW/TZ well head is available in versions suited to 110 and 125 mm casing pipes.
Features of the TW well-head 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 pump suspension eye 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 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 additionally features 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 well head used for?
What is the 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 from surface water, groundwater, and contamination, 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 fitted over the casing pipe from above. The TZ version additionally 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 given 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 you have any doubts, please contact our technical department.
How do I install the well head?
The PE pipe is connected to the pump’s discharge outlet, passed through the well head, and the cable is fed through the cable gland. The pump is suspended from a rope attached to the well head’s eye or link, after which the well head is seated inside or on the casing pipe and the bolts 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.
