Deep-well pump centralizer
The IBO deep-well pump centralizer is a rubber component that stabilizes the pump inside the well casing. Mounted on the discharge pipe, it keeps the pump aligned with the borehole axis and prevents it from shifting during the motor's starting torque. It therefore also serves as a torque shock absorber, protecting the pump and installation from striking the well walls.
For whom
-
Deep-well pump installers – the centralizer keeps the pump aligned with the borehole axis and limits its movement during startup.
-
Well drillers and drilling companies – protection of the pump and casing pipe against impacts during operation.
-
Deep-well owners – quieter pump operation without striking the well walls.
-
Service teams – installation on the discharge pipe with easy pump removal.
Applications
The centralizer is used in deep wells to stabilize a pump suspended inside the casing pipe. It is installed on the discharge pipe above the pump, where it keeps the pump centered. This prevents the pump from shifting during the motor's starting torque and from striking the well walls.
The component is useful wherever a pump operates in a deep borehole and is at risk of shifting during startup. The rubber body adapts to the well diameter, while the steel clamps secure it to the pipe. The IBO deep-well pump centralizer is designed for 1"–1¼" discharge pipes and 4"–8" casing pipes.
Features of the deep-well pump centralizer
The centralizer is made of durable rubber. The longitudinal slots allow its shape to be adjusted to the well size. Bringing the clamps closer together increases its diameter, allowing the component to be adjusted to the diameter of the casing pipe. The clamps are made of stainless steel.
The centralizer is installed on the discharge pipe and tightened so that it does not move along the system. The upper clamp should be tightened more firmly than the lower one, making it easier to remove the pump later. The fit inside the well should not hinder lowering the pump into the borehole.

Frequently asked questions (FAQ) – IBO deep-well pump centralizer
What is the purpose of a centralizer for a deep-well pump?
The centralizer stabilizes the deep-well pump inside the well casing and keeps it aligned with the borehole axis. It prevents the pump from moving during the motor’s starting torque and from striking the well walls. This protects the pump and system from damage.
Which pipes is the centralizer compatible with?
The centralizer is designed for systems with a discharge pipe measuring from 1" to 1¼" and a casing pipe measuring from 4" to 8". The rubber body adapts to the well diameter by adjusting the hose clamps.
How do I install the centralizer?
The centralizer is installed on the discharge pipe and tightened so that it does not move. The upper clamp is tightened more firmly than the lower one, which facilitates subsequent pump removal. The lower clamp should be located 10–20 cm above the pump.
How do I adjust the centralizer to the well diameter?
The centralizer is longitudinally slotted, and its diameter is increased by bringing the hose clamps closer together. It should be adjusted to the diameter of the well, but not so tightly that it hinders lowering the pump into the borehole.
Where can I buy an IBO centralizer?
As the manufacturer, we do not sell directly. The IBO deep-well pump centralizer can be purchased from our trade partners, plumbing wholesalers, and authorized online distributors. Selection depends on the diameter of the discharge pipe and casing pipe.
What is the warranty on the IBO centralizer?
IBO – 24-month (2-year) manufacturer’s warranty. Dambat provides warranty and post-warranty service. For questions about selection, it is best to contact an authorized distributor.
