Baeza Invicta Basic Pro 2020 Replacement Parts

Typical lifespan: 2–3 seasons. It doesn't die suddenly; it degrades—and gives you a warning:

• It takes longer and longer forthe reading to stabilize during calibration
• The calibration is lost within a few days: you calibrate it, and a week later it drifts again
• The value doesn’t match that of your reference analyzer
• You can’t calibrate it even with a new solution

Before buying a new probe (€74.90), rule out the cheap fixes: expired calibration solution (the #1 cause), a dirty bulb (clean it according to the manual), or a connector with moisture.

Why you shouldn’t let it go on: a worn-out probe isn’t just an erroneous reading on the screen—it’s the pump injecting acid based on false information. If you suspect the probe is faulty and can’t replace it right away, switch the pH control to manual mode until the issue is resolved.

The classic season-opening routine. Check-up order, from cheapest to most expensive:

• Reservoir and suction tube: Check that there’s fluid in the reservoir and that the suction tube reaches the liquid. It seems obvious, but it’s surprisingly common
• Foot filter: Remove it and check for white crystallization. Clean it in warm water
• Hardened peristaltic tube: if it has lost its elasticity, the rollers will turn but won’t push
• Air in the suction line: Bubbles in the clear tubing indicate a loose connection or a cracked tube
• Clogged injection point: Limescale gradually blocks it. If the pump draws in liquid but cannot overcome the pipe pressure, check the fitting

Troubleshooting to isolate the problem: if the suction tubing fills with product but it doesn’t reach the pool, the fault is downstream (discharge, injection). If it doesn’t even fill, the problem is in the suction line.

Preventive measure that avoids almost all of these issues: At the end of the season, run clean water through the system for a few minutes to flush the acid out of the circuit.

This is the component that is screwed onto the pipe and through which the pH corrector enters the system. Its name comes from the shape of its check valve, which opens to allow the product to pass through and closes to prevent pressurized water from flowing back toward the pump.

When to replace it:

• It’sleaking at the pipe connection
• It is encrusted with limescale and does not allow the solution to pass through: the pump runs but the pH does not drop
• Water flows back toward the pump when it stops: the valve no longer closes

Maintenance to extend its life: Check it every season. Limescale buildup is gradual, and cleaning it in time prevents the need for replacement. When installing the new fitting (€22.91), make sure it is properly oriented and do not force the thread.

The Invicta line from Baeza comes in several versions, each with its own catalog of replacement parts:

• Basic Pro 2020: this page
• Invicta peristaltic
• Invicta electromagnetic

The most important distinction is between peristaltic and electromagnetic models, because their replacement parts are not interchangeable. Open the head cover:

• If you see a flexible tube curved around rollers → peristaltic (like the Basic Pro)
• If you see a housing with fittings and valves, but no tube → electromagnetic

Another clue without opening anything: the peristaltic model emits a continuous hum while the rotor spins; the electromagnetic model makes sharp, spaced-out pulses.

If you’re unsure, send a photo of the unit and the label via the contact form.

Because the Invicta is built on a platform fr Seko, an Italian manufacturer specializing in dosing equipment, and is sold in Spain at Espaunder the Baeza brand. This is standard practice in the industry.

What this means for you:

• Spare parts labeled “ Seko ” are the correct ones for your pump
• Good long-term availability: since it shares a platform with several active product lines, hoses and consumables are still being manufactured
• When searching for information, try searching for “Seko ” in addition to “Baeza”

The surefire way to get it right every time: compare the old part with the photo on the product page, and if in doubt, send us a picture of the open pump head via the contact form.

On this very page, you'll find direct links to all three:

• Santoprene peristaltic tube (€18.90) — the most frequently replaced consumable
• 1.5-meter pH probe (€74.90)
• Injection fitting (€22.91)

Buying tip: If you’re replacing the probe, add calibration solution to your order —the new probe absolutely must be calibrated, and using an old solution will ruin it right out of the box. You can find it under dosing accessories.
