Seko, and Invikta Replacement Parts

Seko Invikta Metering Pump Replacement Parts: Complete Parts List with Prices

The Invikta is Seko ’s entry-level electromagnetic dosing pump: constant dosing adjustable from 0 to 100% via an analog potentiometer, with a PVDF-T pump head and PTFE (Teflon) diaphragm, designed for liquid chlorine or pH reducers. Since it is electromagnetic—with no mechanical motor or gears—wear and tear is concentrated in three very specific areas: the pump head, the diaphragm, and the ball valves. If your pump also has a pH controller, the electrode is the fourth part to monitor. Here is the complete parts list with prices and links to each part.

Head, Diaphragm, and Valves: The Heart of Dosing

The head, diaphragm, and valves work together with every dosing cycle: if the pump dispenses less than expected or fails to prime, the problem almost always lies in one of these three components.

pH control: electrode

Quick Diagnosis: From Symptom to Part

Before purchasing the pH electrode (€78.90)

It’s the most expensive part in the parts list. Before you decide:

• Calibrate the electrode with calibration solutions before assuming it’s faulty: many erratic readings are due to improper calibration, not a worn-out electrode.
• Check that the electrode doesn’t have limescale or dirt buildup on the sensing tip; gently cleaning it with water may solve the problem without having to buy anything.
• Check the installation date: pH electrodes have a limited service life, typically between 12 and 18 months of continuous use, so if it has already exceeded that period, it’s more likely that it needs to be replaced.

Is it worth repairing or buying a new one?

For a pump in this price range, replacing the head, diaphragm, and valves together costs around €115—a figure you should compare to the price of a new Invikta before making a decision. For isolated malfunctions—such as a faulty membrane or valves alone—repairing is always worth it: these are low-cost parts that have a significant impact on the pump’s performance.

Maintenance that prevents almost all breakdowns

• Clean the ball valves periodically, especially if you’re dosing products that can crystallize or leave residue.
• Visually inspect the diaphragm at least once per season; a diaphragm showing signs of stiffness or cracks should be replaced before it fails completely.
• If you use a pH electrode, calibrate it regularly with calibration solutions to prevent incorrect dosing of pH adjusters.
• Purge the suction line if you notice that the pump frequently loses its prime; trapped air is a common cause of irregular dosing.

Proper maintenance ensures optimal performance. Replace any worn-out parts to extend the service life of your Invikta Seko dosing pump: the pump head, diaphragm, and valves work together in every cycle, so it’s best to inspect them as a set during seasonal maintenance.
