At Q-TECH, we apply the same clear rules for everyone: the law protects you, and when applied correctly, it protects us as well. By processing your purchase, you accept our General Terms and Conditions of Sale. If you are purchasing as a consumer (B2C), nothing stated herein limits the rights granted to you by mandatory law (RDL 1/2007, TRLGDCU): the 3-year legal warranty of conformity and the right of withdrawal under the terms and with the exceptions legally provided, which are detailed below. References to "B2B" apply only to businesses and professionals.

Your guarantees

Rights intact: 14 days of withdrawal from receipt for most products—subject to the legal exceptions you will see below, such as goods made to your specifications—and a 3-year legal warranty of conformity, under the terms of the TRLGDCU.
Conformity with the description: we guarantee that the equipment will correspond to the published technical description and what one could reasonably expect from it (arts. 115 et seq. TRLGDCU). Images and videos are for guidance only: the manufacturer may supply a more recent revision of the product or introduce minor aesthetic, packaging, or firmware changes, without this constituting a lack of conformity as long as the described characteristics and performance are maintained.
Traceability that also protects you: we document the condition, serial number, and seal of each piece of equipment upon shipment, and we video-record the opening of returns; this is your proof of the condition in which the goods were delivered.

Responsible use and your part

If you are thinking of returning it, keep it as you received it: without installing or activating it, with its seals, accessories, and packaging intact. This is how to ensure a full refund, without deductions.
Handling that exceeds inspection reduces value: handling the equipment beyond what is necessary to verify its nature and operation may result in a real, assessed, and case-by-case justified deduction (art. 108.2 TRLGDCU), never a fixed percentage. In particular: activating or registering the serial number, linking it to a manufacturer's account or app, circulating water through hydraulic equipment, unsealing probes, or installing software or consumables. Initial inspection of the product does not lead to a deduction.
The same item must be returned: withdrawal requires returning the supplied unit. Different equipment, or equipment with prior use, age, or wear prior to purchase, does not constitute a valid withdrawal.
Installation and cybersecurity, shared responsibility: this is technical hardware; you are responsible for correct installation, credentials, patches, and backups, while we deliver a compliant product. Q-TECH is not liable for damages resulting from poor installation, incorrect configuration, or omission of patches by the customer or third parties (in B2C, without prejudice to the legal warranty and liability for intent or negligence, arts. 86 and 130 TRLGDCU).
Delivery of bulky goods: delivery is made to the curb. B2C: transport risk is ours until physical delivery (art. 66 ter); we recommend noting visible damages on the delivery note and notifying us of breakages within 24-48 hours with photographs to activate the insurance. B2B: inspection and notation on the delivery note are mandatory; hidden damages must be reported within 24 hours (art. 366 CCom). Unjustified rejection or incorrect shipping information will entail the actual outbound and return costs (approx. €85-550 for heavy machinery).

Made to your measure (Advanced Pre-Assembly)

If your order includes equipment, racks, hydraulic assemblies, or technical rooms made or configured according to your specifications (permanent joints, custom cuts or wiring, parameterization, pressure testing), these are custom goods without the right of withdrawal from the conclusion of the contract (art. 103.c TRLGDCU; CJEU Case C-529/19), which is informed before purchasing and documented in the signed Order Note. A test you request without permanent modification retains your right of withdrawal, with only the actual loss of value caused by that test being deducted. Would you prefer to receive it tested, configured, and ready to connect, without assuming these risks? Contract our Advanced Pre-Assembly or the prior technical audit.

If you are purchasing as a business or professional (B2B)

The transaction is governed by the Commercial Code: firm sale, without the right of withdrawal; notification of defects within 4 days (apparent) / 30 days (hidden), arts. 336 and 342. Q-TECH acts as a distributor and excludes indirect damages, loss of profit, and data loss, limited to the price of the equipment, without prejudice to the manufacturer's commercial warranty.

Filter large volumes of water with a pump you can barely hear

The Saci Magnus is the self-priming pump Saci Pumps builds for community and public pools, from 2.5 to 15 HP. Q-Tech integrates it into pre-assembled plant rooms, where it arrives mounted, wired and tested before it leaves our workshop.

What is the Saci Magnus?

The Saci Magnus is a self-priming public pool pump that moves up to 177 m³ per hour at 1,450 rpm. It draws water through a large pre-filter basket and sends it to the filter. It is installed in the plant room, below or above the pool water level.

What problem does it solve?

A public pool has to turn over its whole volume in a few hours, and the pump runs almost without a break. With a 2,850 rpm motor the noise carries into the pool hall and the rooms next door, and wear arrives sooner.

A pump short on flow forces longer filtration cycles and pushes up the electricity bill; an oversized one punishes the filter. The Magnus covers 32 to 177 m³ per hour at 10 m, so the curve can be matched to the pool and the filter you already have.

When this product is not the right choice

Alternative	When to choose it	Comparable data
Saci Vario Magnus	If you want filtration cycles at different speeds and lower running costs	Same powers, 2.5 to 15 HP; speed adjustable from 870 to 1,450 rpm on the 4-pole models
Saci Supra	If the pool is smaller and less flow is enough	3 to 5.5 HP; 47 to 70 m³ per hour at 10 m; 3 inch or DN 90 connection
Saci eMagnus	If you want the lowest running cost at 5.5 HP and the investment pays off	5.5 HP; IE4 permanent magnet motor; adjustable speed

Frequently asked questions

Which model do I need?

The one that covers your pool's filtration flow at the head of your installation: the model table gives the flow of each one at 10 m. If you do not have that figure, our Expert Technician works it out from the dimensions of the pool and the filter.

Is it suitable for a private pool?

Not usually: the Magnus starts at 2.5 HP and is built for community and public pools. For a domestic pool, Saci has ranges with less flow.

What is the delivery time?

This item is in stock at our warehouse. If no units are available when you place your order, we would order it urgently and let you know the lead time.

Does it work with salt water?

Yes. Saci states that the AISI-316 stainless steel mechanical seal allows the pump to work with salt water; for sea water it offers a silicon carbide seal on request.

Are the counter-flanges included?

No. The DN 100 PVC counter-flange and bolt kit is ordered separately and we have it in the catalogue.

Why is it so quiet?

Because up to 10 HP it runs at 1,450 rpm instead of 2,850 rpm. The 2-pole 2-1250 and 2-1500 do run at 2,850 rpm.

Q-Tech installation and support

Q-Tech assembles the complete plant room in its workshop and delivers it tested and configured, ready to connect: see Pre-Montaje Avanzado and the workshop pre-assembly service. If the pump goes into an existing plant room, the final connection is made by the site installer or by Q-Tech with an on-site day, always after a verification visit. You can see the rest of the range in Saci fixed speed pumps.
