Circulator Pumps and Pump Groups: The Heart of Your Installation
At Q-Tech, we view hydraulics as an exact science. The circulator pump is the vital component that transports energy from your generator (boiler, heat pump, or solar system) to the emitters. Therefore, we do not settle for offering standard replacements; we present a technical selection of high energy efficiency pumps and pre-assembled pump groups designed to comply with the most demanding European Union ErP regulations.
We work exclusively with world leaders in fluid management: Grundfos, Wilo, and DAB for pumping, and ESBE for hydraulic group integration. This combination guarantees silent, long-lasting installations with minimal electrical consumption.
Wet Rotor and High Efficiency Technology (Grundfos, Wilo, DAB)
Old fixed-speed pumps are history. Our range focuses on permanent magnet electronic circulators that automatically adapt their speed to the actual demand of the installation (proportional or constant pressure).
-
Grundfos: Pioneers with the ALPHA1 and ALPHA2 ranges. Their AUTOADAPT technology analyzes the heating system and finds the optimal set point, eliminating noise in thermostatic valves and reducing consumption to historical lows. For commercial applications, the MAGNA3 series offers full connectivity and high-flow management.
-
Wilo: Synonymous with German engineering. Their Yonos PICO and Stratos series stand out for their reliability and "Green Button" technology for intuitive configuration. They are ideal for both replacement (interchangeable with older models) and new installations.
-
DAB Pumps: The EVOSTA series represents the perfect balance between robustness and technology, offering versatile solutions for domestic heating and cooling with a simplified user interface.
Pump and Mixing Groups: The Grundfos ESBE Solution
For professionals looking for excellence and speed of execution, at Q-Tech we recommend the installation of Pre-assembled Hydraulic Groups (Pump Groups). Instead of assembling valves, thermometers, and pumps piece by piece, we offer compact units from the ESBE brand that integrate pumps (Grundfos or Wilo) into a thermally insulated chassis.
-
Mixing Groups (GR Series): Essential for Underfloor Heating. They incorporate a thermostatic or motorized mixing valve that ensures water enters the floor at the exact temperature, protecting the flooring and maximizing comfort.
-
Direct Groups: Ideal for radiator circuits or DHW tank charging, where direct energy transport without mixing is required.
-
Technical Advantages: Drastic savings in labor time, elimination of leaks thanks to factory-tested connections, and a professional aesthetic finish in the boiler room.
⚡ Why trust your hydraulics to Q-Tech?
Selecting a pump is not just about looking at the connection thread. It is a matter of hydronic calculation. At Q-Tech, we bring the value of engineering:
-
Working Curve Calculation: Do you not know if you need a 4-meter or 6-meter head pump? We help you determine the pressure drop of your circuit to select the exact model, avoiding oversizing (noise and expense) or undersizing (lack of comfort).
-
Direct Replacement: We have cross-reference tables to replace your old Baxi, Roca, or discontinued pumps with their modern high-efficiency equivalents, guaranteeing connection compatibility (130mm, 180mm).
-
Regulation Support: We advise you on how to configure your pump (constant vs. variable pressure mode) depending on whether you have radiators or underfloor heating, optimizing the $\Delta T$ of your installation.
