QP Beige filter parts

Replacement parts for the QP Beige laminated filter: strainers, caps, gaskets, and a complete custom-made parts list

The QP laminated filter —the classic beige polyester and fiberglass filter—is one of the most widely used sand filters in Spanish residential pools. Manufactured on the manufacturer’s platform Coral, it shares the same parts list with the Alaska, Volcán, Neptuno, Ciclón, and Rubí laminated series: if you have any of these filters, the parts on this page are the ones you need.

Here you’ll find the complete parts list with prices: strainer baskets in four sizes (70, 100, 140, and 200 mm), lids and gaskets, pressure gauges, diffusers, and elbows by filter diameter, plus replacement parts for the selector valve. All genuine Coral/Productos QP products with the manufacturer’s official warranty (we are an E-Partner).

The key with laminated filters is to identify your filter’s diameter before ordering—we’ll explain how below. And if you have any questions, our technical support team can identify the part based on a photo.

Before ordering: identify the diameter of your filter

Several parts in this parts list (diffusers, elbows) are specified by filter diameter, not by model. You can find it on the filter label (D.400, D.500, D.600, D.780…) or by measuring the body at its widest point: the number in millimeters is your size. With the diameter and a photo of the worn part, your order will be processed on the first try.

QP Laminated Filter Parts List by Section

Zone 2 — Interior: strainers, diffusers, and manifolds

Zone 3 — Fittings and Elbows by Filter Diameter

Zone 4 — Selector Valve Replacement Parts

For the interior components of the valve itself (star, spring, valve cover gasket), see spare parts for selector valves.

The pressure gauge: two minutes to diagnose the entire filter

The pressure gauge is the cheapest part of the breakdown diagram and the one that provides the most information. Memorize its two readings:

• High pressure (above your usual operating pressure): the filter media is dirty → time to backwash and rinse. If the pressure doesn’t drop after backwashing, the sand is compacted or saturated
• Sudden drop in pressure: blockage upstream of the filter (skimmer basket, pump prefilter) or air in the system

Record the pressure with the filter freshly washed: that’s your baseline. When it rises by about 0.3–0.5 bar above that level, backwash. And if the needle doesn’t move or doesn’t return to zero, replace the pressure gauge—it costs €14.54, which is refunded when you return the filter control panel.

Quick Diagnosis: From Symptom to Part

When to open the filter (and what to take advantage of to change)

The natural time to replace internal parts is when changing the filter media (sand every 4–6 seasons; filter glass extends that cycle). With the filter empty:

1. Check all the filter screens one by one: inspect them by hand for cracks in the slots. A single broken screen will allow sand to leak back into the pool
2. Replace the lid gasket even if it looks fine: it costs €21.99 and will ensure a tight seal for years to come
3. Check the top diffuser: if it’s broken, the incoming water will erode the filter bed and reduce filtration quality
4. Take this opportunity to clean the drain and check that it closes properly

Spending an extra half-hour with the filter open saves you from having to open it again in two months.

Can’t find the replacement part for your QP laminated filter—or not sure if your filter is an Alaska, a Volcán, or a Neptuno? The name doesn’t matter: since they share the same platform, almost all replacement parts are interchangeable. Call us at 91 128 55 90 or send us a message via the contact form with a photo of the filter and its label (which shows the model and diameter), and we’ll confirm the exact part for you.
