Solar Panels Plus provides a number of different pumping solutions for solar hot water and solar space heating systems. These pumps are included in our solar water heating packages, and are used to circulate heat transfer fluid in the primary or secondary solar hot water loops.

We have a number of circulation pump solutions for all types of applications, from single family home hot water systems, to industrial heating and air conditioning systems. With a variety of performance curves, they allow for fast, efficient and streamlined installation and operation.

These pumps range in size and flow rate from 3 gpm to 500+ gpm. Materials vary based on need and include bronze, cast iron and stainless steel.

Product configurations include (but are not limited to):

• In-line circulators
• Vertical in-line pumps
• Close-coupled and frame-mounted end pumps
• Multistage pumps
• Variable speed, three speed and manual speed
• Direct current and alternating current in a variety of voltage ranges and amperage draws

If you have a specific job or application, and need help finding a pump solution, please contact us today.

Solar Pump Station

These solar pump stations are used on the solar loop of a solar thermal system to circulate the heat transfer fluid through the array. They are also used to control the temperature in your solar storage tank.

The pump inside the solar pump station is activated by a signal from a solar differential controller. The dual pump station (shown on left) contains both a flow and return connection, and are widely used on most solar thermal systems. A single line return connection pump station is also available.

These pump stations are pre-installed and leak-tested prior to shipping, and are UL-listed for safety. These stations contain a number of important fittings and safety devices critical to the installation and operation of the solar thermal system:

 

• Ball valves in flow and return in combination with check valves prevents unwanted gravity and thermo circulation.
   
• Ports for flushing, filling, and emptying the system, using standard garden hose fittings for easy use.
   
• Air vent allows easy, manual bleeding of the system to remove trapped air build up over time.
   
• Flow meter is included and displays the solar loops current flow. Also allows for adjusting the flow of the solar loop.
   
• Thermometer installed in both the flow and return sides, displaying both temperature sets.
   
• Pressure gauge is integrated and easy to read, allowing for simple, fast monitoring of the solar loops pressure.
   
• Safety relief valve keeps users safe by discharging the solar loop in case of over-pressurization.

Solar Commercial / High Flow Pump Station

The commercial solar pump stations is used on the circulation loop of a solar thermal system for commercial, industrial and other applications requiring high flow, or when a pump is needed to overcome high amounts of head.

Similar to the solar pump station (above), the commercial station is activated by a signal from a solar differential controller. This pump comes with a flow and return connection, with standard 1" male union threads. (Other connection kits available, contact us for details).

These pump stations are pre-installed and leak-tested prior to shipping, and are UL-listed for safety. These stations contain a number of important fittings and safety devices critical to the installation and operation of the solar thermal system:

 

• Wilo Star S-30 Pump supports 1-10gpm flow and up to 30ft of head.
   
• Three speed pump and flow meter allows for easy adjustment and monitoring.
   
• Ball valves and check valves included to prevent gravity and thermo circulation.
   
• Flush, fill, and emptying ports included.
   
• Manual air vent included.
   
• Thermometer & pressure gauge allows for easy monitoring and maintenance on large commercial solar arrays.
   
• Safety relief valve prevents system overpressure, keeping maintenance personnel safe.

DC Solar Pump

The DC solar pump can be used for most circulation pump applications without any connection to a traditional power grid. High efficiency, the DC solar pump can be connected directly to a photovoltaic (PV) panel.

Thanks to it's small size, and high efficiency, it has exceptionally low power consumption. The shaftless spherical motor technology provides a maintenance free, quiet service life.

This pump is perfect for small or single family solar hot water systems, or any other small circulation pump application where conventional power is not available.
