Saci, and Winner Pump Replacement Parts

Yes. The parts listed on this page—prefilter (cover, shut-off valve, O-ring, and basket), 63-mm connection kit, and mechanical seal—are standard across the Winner line, regardless of power rating.

What does vary depending on the power rating are the components of the hydraulic and electrical systems:

• Turbine and diffuser, sized for each power rating
• Capacitor, whose value in mF depends on the motor

For these parts, please contact us via the contact form with a photo of the nameplate (which shows the model, power rating, and capacitor value), and we’ll confirm the part number and availability.

If your Saci pump is not a Winner model, the brand’s catalog can be found under “Pump Parts” at Saci.

Because of the O-ring on the lid. When it "doesn't take in water," it's almost always air entering through the intake, and that's the most common entry point.

Check in this order (starting with the free ones first):

• Water level in the pool: if it’s below the skimmer, the pump is drawing in air directly
• Full baskets: the pump basket and the skimmer basket
• The O-ring: Clean it, lubricate it with silicone, and reinstall it so it’s seated properly. If it doesn’t spring back when pinched, replace it (€9.95)
• Cover and shut-off valve: A cracked cover or a valve that doesn’t seal tightly will let air in even if the gasket is new
• Suction fittings: A poorly sealed connection lets air in just like the cap

Troubleshooting tip: With the pump running, bubbles inside the transparent cap confirm air is entering. If your cap has become opaque from sun exposure and you can’t see anything, replacing it (€22.91) restores the pump’s best diagnostic tool.

Yes, relatively speaking. That specific leak—at the joint between the hydraulic system and the engine—is caused by a worn-out mechanical seal (€15.95).

Why you shouldn’t put it off:

• The water will eventually reach the motor. At that point, the repair cost jumps from €15.95 to the price of a new pump
• Once it starts, it progresses quickly: what’s a single drop per minute today will be a puddle in a matter of weeks

It usually appears at the start of the season, after months of inactivity: the seal dries out over the winter and no longer seals properly when the pump is put back into service.

When replacing it, also check the condition of the shaft and clean the inside of the housing. If disassembly proves difficult, consult technical support before forcing anything.

The 63-mm PVC fitting kit (€27.04) includes the components needed to connect the pump to piping of that size.

When it’s worth it:

• Leaks at the connection to the plumbing system that cannot be fixed by retightening
• Cracked fittings or those with damaged threads
• New installation or relocation of the pump, where you’ll be redoing the connections

Before ordering, confirm that your system uses 63 mm piping: measure the outer diameter of the PVC pipe connected to the pump. If your system uses a different size, contact us via the contact form and include a photo of the connection.

Installation tip: When reconnecting the lines, take the opportunity to check the alignment of the pipe with the pump. A forced connection transfers stress to the pump body and can lead to cracks.

When it breaks, it’s not according to a schedule. And it breaks for two reasons, both of which are preventable:

• The strain of pulling it out when it’s full and heavy: this is the number one cause
• Cracks caused by sun exposure and chemicals after years of use

Don’t leave it with a broken basket: anything that slips through goes straight into the impeller. Hair is the worst, because it wraps around the shaft. For €12.29, you can protect the pump’s entire hydraulic system.

Routine to make it last: empty it every week (daily during leaf-fall season), rinse it with a gentle water jet, and seat it securely before closing the lid. A poorly positioned basket lets debris through just like a broken one.

Stop tightening it. That’s the fastest way to break the lock (€16.50) or crack the cover (€22.91), turning a €9.95 repair into a €40 one.

If the cover leaks when tightened normally (with a firm hand, without a tool), check:

• The gasket seat: Clean away any limescale or dirt that’s preventing a proper seal
• The gasket: if it’s flattened, hardened, or twisted, replace it and install it with a thin layer of silicone
• The lid: check for fine cracks, which can sometimes be hard to see, especially around the seat
• The shut-off valve: if it doesn’t tighten securely or you notice any play, it’s worn out

A rule that applies to the entire prefilter: it’s the gasket that seals, not force.

With the breakdowns listed on this page, repairing is clearly worth it: the most expensive part is the connection kit (€27.04), and the rest range from €9.95 to €22.91. Even when you add up the cost of the prefilter and the mechanical seal, the total is still far less than the price of a new pump.

• Don’t hesitate to repair it: the complete prefilter, mechanical seal, connections, and also the impeller, diffuser, or condenser if that’s what’s failing.
• Consider replacing the pump when the failure is in the motor (burnt-out windings, bearings), when the housing is cracked, or when several serious failures occur at the same time

The 60–70% rule: if the repair cost exceeds that percentage of the price of an equivalent new pump, replace it. See our catalog of pool pumps.

One factor that sometimes tips the scales: the pump is the piece of pool equipment that consumes the most electricity. If yours is many years old and runs for long hours in the summer, a variable-speed pump can pay for itself sooner than you might think.

This page lists the parts typically required for routine maintenance: prefilter, connections, and mechanical seal, which cover the vast majority of issues. For the rest— turbine, diffuser, condenser, fan, terminal box, and housing —we use the manufacturer’s complete parts list.

How to order:

• Call 91 128 55 90 or fill out the contact form
• Attach a photo of the pump, the nameplate, and the part to be replaced
• If you know the part number in the manual’s exploded view, please provide it: this is the fastest and most accurate way

With this information, we’ll locate the exact part number and confirm the price and delivery time. We’ll also help you narrow down the diagnosis before you buy, which is especially useful when the suspected part is expensive.

On this same page, you'll find the exploded view with direct links to each part:

• Prefilter: O-ring, basket, shut-off valve, and cap
• Hydraulics and connection: mechanical seal and 63 mm connection kit

Purchasing tip: If you’re going to open the prefilter to replace the basket or cover, add a new gasket to your order. It’s the part that fails most often, and you’ll already have the pump open.

Shipping within 24–48 hours to mainland Spain for in-stock replacement parts; free shipping on orders over €150. For the rest of the Winner’s parts list, contact us and we’ll help you find them.
