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.

What is the Saci Kontra?

The Saci Pumps Kontra is a high-flow centrifugal pump that runs at 1,450 rpm up to 10 HP. It is designed to give the pool the flow rate needed for counter-current swimming, and to serve fountains, cascades or water parks.

What problem does it solve?

In a public pool, plant room noise carries to the pool hall and the surrounding areas. Pumps at 2,900 rpm make themselves heard; the Kontra runs at half the speed across most of the range, with bearings greased for life.

The second problem is how robust the assembly is. The DN110 standard flanges and the wide support base spread the loads of the pipework, which at high flow rates are the usual cause of leaks and vibration.

Compatibility and limits

  • Counter-flanges are not supplied as standard: order them separately, for example with the flange kit for Saci pumps.
  • Suitable for sea water and for salt-chlorinated water thanks to the carbon-ceramic and AISI-316 seal.
  • The whole range is three phase; from 7.5 HP upwards, 400 V only.
  • It has no pre-filter: the water reaches it already filtered by the treatment circuit.
  • The 12.5 and 15 HP models run at 2,850 rpm, so they do not share the noise level of the rest of the range.

Frequently asked questions

Which model do I need?

It is chosen by the flow rate and head at the duty point. At 10 m³ per hour the 4-250 gives 32 m and the 2-1500 reaches 177 m. Send us the scheme and we will place it on the curve with you.

Why is it quieter?

Because it runs at 1,450 rpm up to 10 HP, half the speed of a two-pole pump, with bearings greased for life.

Are the counter-flanges included?

No. Saci supplies them on request and they are ordered separately.

Does it work with sea water?

Yes, according to Saci, thanks to the carbon-ceramic and AISI-316 stainless steel mechanical seal.

Is there a bronze impeller version?

Saci makes it on request. Ask us and we will confirm lead time and conditions.
