This pump station is a pre-installed and leak-tested unit with fittings for transferring heat from the collector to the storage tank. It contains important fittings and safety devices for the operation of the solar thermal system.

The Solar Pump Station Product Line from Purist simplifies the installation of Solar Hot Water Systems by eliminating the guesswork, research, and labor involved in these systems.  The Pump Station is combined with any solar collector and storage tank to provide a complete solution.

Transmission station Regusol E-130 and Regusol EL-130 with pre-assembled, integrated microprocessor-driven control.

Compared to the Regusol E-130, the Regusol EL-130 is equipped with a de-aerator for the de-aeration of the heat transfer medium.

 • Ball valves in flow and return in combination with check valves to prevent gravity and thermo circulation.
 • Unit for flushing, filling and emptying the system.
 • Air vent for manual bleeding of the solar thermal system.
 • Flow meter for displaying and setting the flow rate.
 • Thermometer in flow and return for displaying
both temperatures.
 • Pressure gauge for displaying the system pressure.
 • Safety relief valve to prevent overpressure.
 • Three-speed solar pump for wide range of flow rates.
 • Base pump station is not equipped with a controller - must be ordered separately

   Purist Energy merges time-proven system designs with the best available components to make a product that meets the expectations of the modern homeowner.  The Solar Pump Station is a prepackaged solar hot water appliance that includes most components required for a solar hot water installation in a single, compact unit.

   The Regusol 130 EL is a pumping station for solar hot water systems. It is available with a differential temperature pump controller.

Product range:

Code 255050A Dual line pump station, flow and return connection, flow meter scale:
 • 1/2–5 gpm
 •  size 3/4"

Code 256050A Single line pump station, return connection, flow meter scale:
 • 1/2–5 gpm
 • size 3/4"

Efficient Design:
    The Pump Station has been designed with the most efficient components available to reduce power consumption while providing maximum heat collection and functionality.

   Integrated in a compact, insulated, wall-mounted box are all of the components necessary for clean, efficient solar design.

Full-functioned:
   The SPS is clearly labeled and simple to operate.  The digital display shows collector and storage temperatures and allows simple setting adjustments during system startup.  The closed-loop antifreeze system design provides protection from freezing, while the controller provides over-temperatuure protection.  PC connectivity is standard on every unit!

Included components:

• Circulator pump
• Ball valves with integrated temperature gauges on supply and return sides
• A de-aerator with manual vent
• Visual flow indicator
• Pressure relief valve and gauge
• Two drains and a port for expansion tank connection
• Electric temperature differential controller

Flexibility:
   The Solar Pump Station product line has been developed to provide several options for maximum flexibility.  DC and AC powered systems use the same piping components and enclosure.  Dual and single pumped systems are available for use with different storage tanks or water heaters.  The SPS can be used with several collectors for larger systems.
