Plug and Play Hydronic heating and cooling solutions with PAW Modular Zone Pump Stations. With German Engineered PAW modular pump stations you can design heating system quickly while delivering the highest performance and quality standards in the industry. The PAW Zone pump module quickly connects to a centralized distribution manifold allowing you to share the heat source to multiple zones. Now you can easily design a complete home hydronic system that can do radiant floor heating, domestic hot water, radiators and fan coils, as well as pools and hot tubs. All with one single boiler connection. The K31 with 1” NPT connections is used for high heating zones that do not require mixing. This can be most zones such as domestic hot water, fan coil radiations and pools or hot tubs. For Hyronic radiant floor heat you should use the K32 Model with electronic mixing valve.

Now you can easily design a complete home hydronic system that can do radiant floor heating, domestic hot water, radiators and fan coils, as well as pools and hot tubs. All with one single boiler connection. The K32 with 1” NPT connections is used for low temperature heating zones that require lower output temperatures such as hydronic floor heating. The built in electronic mixing valve is used for Heating Curves that optimize the system’s performance. Using precise temperature control, the electronic mixing valve receives signals to open and close depending on the heating curve, supply temperatures and outdoor temperatures. In this way your hydronic heating zones always stay constant with no fluctuations. The mixing valve diverters’ colder radiant return water with hotter supply water to give your system the exact temperature required.

Grundfos ALPHA2 26-99FC Variable Speed Circulator Pump with AUTOADAPT PN-99490916 PN-99490916, 1x115V 60Hz, Check Valve Included The Grundfos ALPHA2 26-99 is a medium sized, energy efficient 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. AUTOADAPT functionality enables the ALPHA2 26-99 to control operation automatically within a defined performance range. When set in proportional pressure AUTOADAPT or constant pressure AUTOADAPT, the pump will automatically analyze the heating system, find the optimum system curve and duty point and continue to adjust its operation to changes in demand. A magnetite resistant design, robust ceramic shaft and stainless-steel bearing plate ensure that the ALPHA2 26-99 reliably delivers the optimal system flow at the lowest possible energy consumption. ALPHA2 26-99 circulator pumps are designed for circulating liquids in heating and airconditioning systems. These circulators are equipped with a conduit box for easy installation of the power cable. ALPHA2 26-99 models are internally controlled and are designed for systems with variable flow rates, where the pump is internally controlled via a user interface. Speed control can reduce power consumption considerably. Grundfos ALPHA2 26-99FC Features: 8 intelligent control modes: Three defined proportional pressure curve settings Three defined constant pressure curve settings Constant pressure AUTOADAPT Proportional pressure AUTOADAPT Magnetite resistant design protects the pump from harmful iron oxide found in heating systems High efficiency pump design and controls reduce energy consumption by up to 85% 360 [mNm] starting torque clears pump of system debris and sediment Designed with trusted ECM technology which has been used by Grundfos for more than 16 years System and pump protection warning and alarm indicators LED light indicators for pump settings and alarms Easy to use push button control settings Designed using 65+ years of hydronic heating experience Applications: Closed loop radiant heating & snow melting systems, solar thermal secondary loops Baseboard/Radiator/Fan coil heating and other hydronic heating applications.

Solar Feed Pump Station - ST-Pump-Feeder-MF 200 - S MODEL MF200-S ‘SOLAR PAL’ MINI SYSTEM FEEDER The ‘SOLAR PAL’ is designed for application with Solar systems collectors typicaly mounted high on the structure that may require higher static fill pressures than conventional residential and light commercial projects. The system feeder can provide fill pressure as high as 35 psig. It is compatible with water and most commonly used anti-freeze solutions. NOTE – the system pressure relief valve must be rated to handle the higher pressure. Do not use the MF200-S in any application with a 30psig relief valve. Features: 22.7 liter (6.0 US gallon) tank for storage and mixing Power supply plugs into any standard 115 VAC outlet Diaphragm pump can run dry without damage No direct connection to potable water supply eliminates need for backflow prevention Make-up fluid stored in the feeder tank can be pre-treated Diverter valve allows easy purging of air on initial start-up, and manual agitation of solution Prevents major floods - in the event of system rupture, only the contents of the tank will be pumped into the system Provides leak detection - dropping fluid level provides immediate notice that the system has developed a leak Fluid drained for service can easily be put back into the system Fluid level switch shuts the pump off if the storage tank level gets too low Auxiliary dry contact included for remote low pressure alarm (alarm optional or by others) ELECTRICAL: Fused Power supply adapter 115/60/1 to 24 VDC Rated 50 watts AC LED Power Light PUMP PERFORMANCE: 0.04 l/s (0.7 gpm) @ free flow Self-priming up to 1.2 m (4 feet) +
