    El sid pump

    El Sid Solar Circulating Pump
    Model SID3.5PVSS

    3.5 Watts
    12 Volt
    DC Voltage

    Lead Free
    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 SID3.5PVSS
      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.
