Replacement Parts for the Jardino Pool Nox 75/100/150 Pump: Complete Parts List from the Prefilter to the Motor

If your pool filter system has a pump labeled “Jardino Pool,” you’re in the right place—and it probably took you a while to find it. Jardino Pool is the brand name under which pumps manufactured by ESPA are distributed, specifically the Nox series in its 75, 100, and 150 versions. That’s why the replacement parts you need are genuine ESPA parts, even if the housing says otherwise.

Here is the complete parts list for the Jardino Pool Nox with prices, organized into four sections: pre-filter, hydraulic body, motor and electrical components, and mounts. All genuine ESPA parts with the manufacturer’s official warranty—we are an ESPA E-Partner.

Two tips that will save you from having to return a part, which we’ll explain below: the model number indicates the power rating (75 = 0.75 CV, 100 = 1 CV, 150 = 1.5 CV), and the mechanical seal was changed in 2007.

Jardino Pool, ESPA, and Nox: Why Three Names for the Same Pump

This is the most common source of confusion on this page, and it can be explained in three lines:

• Jardino Pool is the brand name under which the unit is sold (often as part of a complete filtration system kit)
• ESPA is the pump manufacturer
• Nox is the technical platform on which it is built, with versions 75, 100, and 150 based on power output

Practical tip: When looking for replacement parts, search for “ESPA Nox,” not just “Jardino Pool.” And if your pump is a Silen S, its specific parts list is under “ESPA Silen S pump replacement parts ”—they share many parts, but not all of them.

The number indicates the power rating

Model	Power	Power supply
Nox 75	0.75 CV	Single-phase (standard household power)
Nox 100	1 CV	Single-phase
Nox 150	1.5 CV	Single-phase

 

You’ll find this information on the motor ’s nameplate, along with the power rating in kW and the capacitor value in mF —the key piece of information if you’re ordering a capacitor. The impeller and diffuser also depend on the power rating.

Breakdown of the Jardino Pool Nox by sections

Zone 1 — Prefilter

Replacement Part	Estimated price	When to replace
Prefilter basket	€11.89	The basket that catches leaves and hair. Replacement No. 1: It breaks when emptied too quickly or cracks from sun exposure.
Pre-filter cover	€11.34	The transparent lid. Replace if it is cloudy, cracked, or if the gasket seat is damaged.
Pre-filter Lock Nut	€13.46	The threaded ring that secures the cover. Replace if the threads are stripped or cracked.
Pre-filter O-ring	€2.95	The number one cause of pumps that won’t prime: a worn O-ring allows air to enter even if not a single drop of water comes out.
Pre-filter opening wrench	€5.90	The official tool for opening without causing damage. Cheaper than the cap that gets broken when you pry it open with a screwdriver.

 

Zone 2 — Hydraulic System

Replacement Part	Estimated Price	When to Replace
Mechanical seal (2007 and later)	€28.50	The seal between the hydraulic system and the motor. If there’s a leak at the joint between the housing and the motor, it’s this part. Keep an eye on the age (see below).
1 CV turbine	€14.75	The impeller. Replace if it has broken blades or wear that causes a loss of flow.
1 CV Diffuser	€6.38	Channels the water to the turbine outlet. Comes as a set with the turbine.
Diffuser gasket	€2.90	Replace it whenever you open the housing.
Body O-ring	€3.75	Same as above: 3.75 €, which prevents you from having to open it again.
Pump body with accessories	€69.90	The complete hydraulic body. The solution when the housing is cracked—typically due to ice.
Connection fitting	€11.10	The connection to the piping.
Connection fitting gasket	€2.90	If there’s a leak at the connection, start here.
Drain plug	€1.95	The one you open for winterization. It must close tightly.
O-ring for the plug	€1.95	Its gasket.

 

Zone 3 — Engine and Electrical Systems

Replacement Parts	Estimated Price	When to Replace
12 mF capacitor	€9.90	Order the same mF value as indicated on your circuit board or the old capacitor. Never just use “whatever fits.”
16 mF capacitor	€9.95	Same as above—the value is what matters.
25 mF capacitor	€10.90	Same as above.
Thermal protector	€5.15	The protector that shuts off the motor in case of overheating. If the pump stops on its own and starts up again after a while, suspect this component—but first investigate why it’s overheating.
Nox Terminal Block	€5.70	The junction box. Replace it if it’s cracked or moisture has gotten inside.
Nox Terminal Box Cover	€4.90	Cheap but dangerous: a terminal box exposed to water will lead to an electrical failure.
Fan	€2.90	The cooling fan. Broken = overheated motor = circuit breaker tripping.
Fan cover	€3.94	The grille. Never operate the pump without it: without the cover, air won’t circulate properly.

 

Zone 4 — Mounts and Vibration Dampers

Replacement Part	Estimated Price	What it’s used for
Mount	€21.90	The mount for the motor-pump assembly.
Base	€7.95	The support foot.
Silent block	€1.95	The anti-vibration pad. If the pump has started making noise, start here: these hardened pads transmit all the vibration to the baseplate.

 

The mechanical seal and the 2007 redesign

ESPA modified the mechanical seal for this platform in 2007. The replacement part shown on this page is for pumps manufactured starting that year.

Before ordering:

• Check the nameplate: next to the model and powerrating, you’ll find the year or production lot
• If your pump was manufactured before 2007 or you can’t determine its date, send us a photo of the nameplate via the contact form, and we’ll confirm which part fits.

A telltale sign: constant dripping from the joint between the hydraulic housing and the motor, which usually occurs at the start of the season. Don’t ignore it—water will eventually seep into the motor, and the repair cost will jump from €28.50 to several hundred.

Quick Diagnosis: From Symptom to Part

Symptom	Most Likely Cause	Part to Check
The pump does not prime / loses prime	Air entering through the prefilter cover	Pre-filter O-ring (€2.95), cover, and nut
Leaking between the body and the motor	Mechanical seal worn out	Mechanical seal
It hums but won’t start	Capacitor worn out	Capacitor with the same value in mF
It stops and starts again after a while	Overheat alarm sounding	Cause of overheating: dirty filter, broken fan, clogged basket. Then, the buzzer sounds
Loss of airflow even with a clean filter	Worn blower or damaged diffuser	Impeller and diffuser
New noise and vibration	Hardened silent blocks	Silent block, foot, mount
Crack in the housing after winter	Ice inside the housing	Complete pump housing
Leak at the pipe connection	Fitting gasket	Gasket before the fitting

 

Maintenance that extends the life of the Nox

• Empty the prefilter basket every week during the season. A full basket forces the motor to work against a wall—and is the indirect cause of half of all blown fuses
• Lubricate the lid’s O-ring with silicone once or twice per season
• Open the drain plug when storing the unit for the winter. Frozen water inside the body is what causes the casing to crack: a well-used €1.95 drain plug saves you €69.90 on a new body
• Check the terminal box at the start of the season: moisture, rust, or a loose cover can lead to an electrical failure
• Never run the pump without the fan cover

Can’t find the replacement part for your Jardino Pool? Call us at 91 128 55 90 or send us a message via the contact form with a photo of the nameplate —model, power rating, capacitor value, and year are the four pieces of information that will get you the right part on the first try, even if the housing says “Jardino Pool” and the replacement part says “ESPA.” And remember the simple step that saves the most pumps every winter: open the drain plug when the season ends.
