    El sid pump

    El Sid Solar Circulating Pump
    Model SID3.5WPV-12V

    DC Voltage

    Stainless Steel

    • No bearings to get hot
    • No leaky seals
    • No moving parts
    • 4 LEDs glow when impeller is spinning
      SID stands for static-impeller driven, which means the pump contains an electronic driver or motor that has no moving parts but simply spins on a magnetic field. The magnetic field grasps the impeller and visibly spins it without any moving parts or seals. As a result, it's extremely long-lived without much power consumption. These pumps are completely stainless steel so they don't corrode.

      The El SID pumps have no seals which can leak, and no bearings to get hot or brushes to spark - they are explosion proof.

      Model SID3.5WPV-12V
      A 3.5-watt driver, intended for PV domestic hot water and instant hot water circulation without glycol. Requires a 5 watt Amorphous/CIS module or larger such as Shell ST5. It is rated for 2.0gpm and can be used in open loop water systems with one 4x10 solar collector.

      Product Applications:
      • PV-Direct Applications
      • Solar Domestic Water Heating Systems - closed loop
      • To be used with a 5 watt amorphous pv panel [not included]

      Product Function:
      This pump is used to circulate the water throughout the radiant panel or other hot water heat emitting system.

      Product Advantages:
      • Use a small, inexpensive PV module (photovoltaic panel) to power the pump. No battery or electronic controller is used. There is no wiring to the building's electric system.
      • Sun-synchronous operation: pump speed varies with sunlight, corresponding to the available heat in the collector—natural automation!
      • This principle has proven highly reliable in solar water heaters since the early 1980's.

      Product Features:
      • Stainless steel construction
      • Power source AC/DC
      • High efficiency - typical start 1 watt
      • Magnetic coupled drive
      • Locked impeller protected [PV]
      • No shaft - no fan
      • Brushless motors
      • No maintenance required
      • Quiet operation

      LED Signals
      Four red LEDs will glow when the impeller is spinning. Two will light if the impeller is stuck, one above and one below.

      Product Specifications:
      • 3.5 Watts
      • Max Head 1.8 ft
      • Max Flow 2.0 gpm
      • Light weight - 2 lbs
      • Compact size: 2.75" sq - 3" thick
      • Low voltage [class II] driver
      • High temperature - 250°F fluid max.
      • High pressure - 175 psi. max
      • Vertical or horizontal piping


      Shown is 1/2" female NPT adapters and 1/2" pipe. Also shown are the heads of four Philips screws that fasten the 2W2 driver onto the head.

      Wetted materials are:
      • Food Grade Stainless Steel
      • Teflon
      • Hi-Temp ROYTON Plastic
      • Ceramic Ferrite Magnet

      Four common screw heads are shown, holding the stainless steel fluid retaining plate in place. Also shown are four screws coming from the back of the pump head. When the 2W2 driver is in place, a total of eight screws squeeze the fluid retaining plate in place.

      Note that there is no shaft and [of course] no shaft-seal. The crown at the center of the retaining plate houses an eight pole ceramic magnet. Thus, the rotating magnetic field in the 2W2 driver is coupled to the impeller, which resides in the fluid.

      Easy to install
      The stainless steel pump is soldered into your copper plumbing, and the driver screws on top of it. Any driver [regardless of size] can be interchanged on the same pump, which means that if the pump doesn't provide the flow you need, you can install a larger driver within a couple of minutes.
