Microdos MP1 Peristaltic Dosing Pump – Replacement for CCEI Controllers

Is the dosing pump on your CCEI controller no longer working correctly? Is it injecting irregularly, making abnormal noise, or not starting? The Microdos MP1 peristaltic dosing pump is the original replacement part designed for all compatible CCEI controllers and electrolyzers. It ensures precise and constant injection of treatment products — pH minus, pH plus, flocculant — to maintain a perfectly controlled water balance without manual intervention.

It is an essential component in any automatic water treatment system. Without a functional dosing pump, even the best controller on the market becomes incapable of correcting pH or injecting the product at the right time. Quickly replacing a faulty pump prevents water imbalances, irritations, and premature equipment degradation.

Compatibility with CCEI Controllers and Electrolyzers

The Microdos MP1 is the reference peristaltic dosing pump for the CCEI range. It is compatible with the following devices:

  • Limpido XC LAB
  • Limpido Pro pH
  • Limpido Pro Lab
  • Phileo and Phileo LT
  • Oxeo, Oxeo LT and Oxeo SP
  • Equalizo DUO

This list covers most of the installed CCEI controllers among individuals and professionals. If you own one of these devices and your dosing pump shows signs of failure, the MP1 is the part to order.

How does a peristaltic dosing pump work?

Unlike a diaphragm pump, a peristaltic pump operates by progressive compression of a flexible tube — the Santoprene tube — between a rotor and a fixed wall. This "peristaltic" movement creates a regular and perfectly metered suction and discharge of the treatment liquid, without the chemical product ever coming into contact with the mechanical parts of the pump.

This principle offers several decisive advantages for use in pool water treatment: the pump is insensitive to corrosive products such as acids used to lower pH, it does not clog, and its flow rate remains constant and reproducible cycle after cycle. Injection accuracy is thus guaranteed over time, which is essential for reliable automatic regulation.

Simple installation, reduced maintenance

Replacing the MP1 dosing pump does not require technician intervention. The pump comes with its connector and Santoprene tubing, ready to be connected to your controller. Simply disconnect the old pump, connect the new one in the same location, and check the tightness of the fittings before putting it back into service.

The supplied Santoprene tube is the main consumable for this type of pump: it wears out gradually over cycles. Its lifespan depends on the frequency of use and the injected products, but it is easily replaceable independently of the pump itself when it shows signs of wear (cracks, loss of flexibility, leaks).

When to replace your dosing pump?

Several signs indicate that it is time to change the dosing pump of your CCEI controller. Irregular dosing often results in unexplained pH variations despite correct probe calibration. An abnormal clicking or vibrating noise can indicate wear of the tube or rotor. A product leak around the pump, or conversely a total absence of injection verifiable by observing the outlet hose, are clear signs of failure.

In all these cases, replacing the dosing pump is the quickest and least expensive solution before considering replacing the entire controller. The MP1 is a normal wear part on an automatic treatment system used for several years — anticipating its replacement is part of rigorous maintenance of your installation.

An original part for preserved performance

By choosing the Microdos MP1, you are opting for the original part recommended by CCEI for its controllers. Using a non-compliant replacement dosing pump can lead to flow, sealing, or electrical compatibility problems with the controller. The MP1 guarantees seamless integration and identical performance to the original, so that your automatic treatment system continues to function exactly as intended.

Delivered with its connector and Santoprene tubing, it is ready to install upon receipt, without having to order additional parts.

Frequently Asked Questions about the Microdos MP1 Peristaltic Dosing Pump

What is a peristaltic dosing pump and how does it work? +

A peristaltic dosing pump works by progressively compressing a flexible Santoprene tube using rotating rollers. This mechanism creates a regular and precise flow of the treatment liquid (pH-, pH+, disinfectant) without contact between the chemical product and the mechanical parts. This principle ensures accurate injection and consistent flow rate, and simplifies maintenance since only the tube is in contact with the product.

Which CCEI devices is the MP1 pump compatible with? +

The Microdos MP1 pump is the official replacement part compatible with the following CCEI regulators: Limpido XC LAB, Limpido Pro pH, Limpido Pro Lab, Phileo, Phileo LT, Oxeo, Oxeo LT, Oxeo SP and Equalizo DUO. Its original connector ensures direct connection without modification. If you have any doubt about compatibility with your device, refer to your regulator's supplier reference.

What is the flow rate of the MP1 pump and what pool size is it suitable for? +

The Microdos MP1 pump delivers a maximum flow rate of 1.8 liters per hour at a maximum pressure of 1 bar. This flow rate meets the needs of residential pools up to approximately 120 m³, in accordance with the CCEI regulators it is associated with. The proportional injection controlled by the regulator automatically adjusts the dosage according to the actual needs of the water.

How do I replace the dosing pump on my CCEI regulator? +

Replacement is quick and easy. Start by cutting off the power supply to your regulator. Disconnect the electrical connector from the old pump and remove the Santoprene tube fittings. Install the new MP1 pump by reconnecting the connector and attaching the supplied tube. The MP1 comes with its connector and Santoprene tube ready for use, no special tools are required for installation.

When should the dosing pump of my pH regulator be replaced? +

Several signs indicate that a dosing pump needs to be replaced: absence of injection despite the regulator being triggered, unusual motor noise, leakage at the Santoprene tube, or a pH that no longer stabilizes despite correct probe calibration. The Santoprene tube wears out over time and should be replaced every 1 to 2 years depending on the intensity of use, even if the pump is still working.

What is a Santoprene tube and should it be replaced separately? +

The Santoprene tube is a high chemical resistance thermoplastic elastomer that is the main wear part of the peristaltic pump. It is compressed by the rollers to create the flow. The MP1 pump comes with its Santoprene tube with dimensions 4 x 7 mm. If only the tube is worn but the motor is still working, it is possible to replace only the tube to reduce maintenance costs.

Can the MP1 pump inject both pH+ and pH-? +

Yes, the Microdos MP1 pump is compatible with acidic and basic pH correction products (pH- and pH+) as well as liquid disinfectants used in CCEI regulators. Its high chemical resistance thanks to the Santoprene tube allows it to dose aggressive products safely. Always check the concentration of the products used to stay within the limits recommended by CCEI.

Should the dosing pump be winterized at the end of the season? +

Yes, proper winterization significantly extends the pump's lifespan. At the end of the season, rinse the injection circuit by running the pump for a few minutes with clear water to flush out any chemical residue. Then cut the power and leave the Santoprene tube in a relaxed position if possible. Avoid exposing the pump to frost, as product residues could crystallize and damage the tube.

What does the MP1 pump kit contain? +

The Microdos MP1 pump kit contains 1 complete peristaltic pump, its electrical connector for direct connection to the CCEI regulator, and its Santoprene tube with dimensions 4 x 7 mm. Everything necessary is included for immediate replacement without purchasing additional accessories. The pump is ready to be installed upon receipt.

What is the difference between a peristaltic pump and a diaphragm pump? +

A peristaltic pump, like the MP1, uses a flexible tube compressed by rollers to move the liquid. It is very reliable, easy to maintain (only the tube wears out), and handles aggressive chemicals well. A diaphragm pump uses a diaphragm that deforms to create suction and discharge. Peristaltic pumps are generally quieter and more precise for low flow rates, making them the preferred choice for pool pH regulators.
