ALPHA 15-55 HWR-D. The ALPHA 15-55 HWR-D is a recirculation system that delivers hot water in homes at the push of a button and can save thousands of gallons of water each year. The system includes an ALPHA 15-55 circulator pump (with a permanent magnet motor), a temperature sensor and two push button controls. Literature - General Brochure Information and advice. Grundfos is a world-wide provider of pumps and related systems. We have a trained staff of service engineers who will be able to support you during the installation phase of the pump or solution. GRUNDFOS ALPHA2 L is a complete range of circulator pumps with integrated differential-pressure control enabling adjustment of pump performance to the actual system requirement. The pumps are energy-optimised and comply with the requirements of the EuP directive EuP 2015. The Grundfos ALPHA2 circulator with AUTOADAPT are predicated on: 65-years of hydronic experience of how pumps work in countless applications and operating environments; 15+ years of ECM motor experience in the market; ALPHA2 materials and design resist blockage from magnetite and iron oxide particles found in closed hydronic systems.
The Grundfos ALPHA2 26-99 is a medium sized, energy efficiency circulator fitted with a permanent magnet motor (ECM) and frequency converter. Featuring eight different operating modes including constant pressure AUTOADAPT and proportional pressure AUTOADAPT, the ALPHA2 26-99 is the perfect fit for any heating application. The pump valve is leaking out of the gland, when you change the pump replace the valves for gate valve type, they are much less prone to leaking. I'd also suggest going for a wilo pump, the new grundfos alphas are pretty unreliable (I've fitted Grundfos exclusively for nearly ten years before the new pumps were introduced).
Adjustment of the pump’s performance in the summer to the warmer temperature outside – giving customers extra energy efficiency. Magnetite resistance: Ensures that no small pieces of metal get stuck in the pump’s vital parts when they are magnetised. Dry-running protection: Makes sure the pump never runs without liquid in the system Boasting the lowest warranty return rate of any circulator, the Grundfos ALPHA product line replaces more than 30 pump models. Not all circulators are created equal – be genuine ALPHA1 The ALPHA1 is the latest expansion to Grundfos' world-renowned ALPHA product line, providing customers with the flexibility to select the most appropriate ...

Jan 04, 2017 · I've been looking in this forum for similar problems at it seams the Alpha 2 isn't without its problems. We've got a Grundfos Alpha 2 15-60 130. Fitted by British Gas 3 years ago, it's been fine but this winter it's be really quite noisy regardless of what setting I switch it to. GRUNDFOS has made a few crucial design changes that allow you to use the new ALPHA2 now in cooling applications with pumped liquid temperatures down to +2 °C. This means that the new ALPHA2 will not only cover your heating demands, but also up to 90 % of your airconditioning and cooling demands.
ALPHA3 - easy hydronic balancing. The ALPHA3 is our newest circulator for domestic buildings. It is of the Grundfos quality and guarantees easy installation, market leading energy efficiency and reliable operation in the toughest conditions. The installation of a GRUNDFOS ALPHA2 (N) pump will decrease the power consumption considerably, reduce noise from radiator valves and similar fittings, and improve the control of the system. The unique Grundfos AUTOADAPT function ALPHA2 (N) will analyse and adjust automatically to your heating and water use demands. viscosity, the hydraulic performance of the pump will be reduced. Example: 50 % glycol at 20 °C means a viscosity of approx. 10 mm2/s (10 cSt) and a reduction of pump performance by approx. 15 %. Do not use additives that in any way can/will disturb the functionality of the pump. When selecting a pump, take the viscosity of the
