    El Sid Solar Circulating Pump - Battery OperatedEl Sid Solar Circulating Pump - Battery Operated
    Model SID-B Series

    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 brass and 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.

    Product Applications:
    • Solar Domestic Water Heating Systems - closed loop
    • Floor Heating Systems

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

    Product Features:
    • Brass and 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
    • 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:
    • 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

    All Drivers are Static Impeller Drivers™. SID™ and look the same; see circuit board for model#.

    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
    • Cast Bronze
    • 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 brass 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. 

    Battery Operated Models:

    SID10B12
    A 10-Watt driver used with 12-volt battery systems. The speed of this driver will change with battery condition (voltage). Often used in radiant floor application, etc.

    SID10B24
    A 10-Watt driver used with 24-volt battery systems. This driver has a built in dc-dc converter, causing the pump to be "constant-speed" from 20 to 35 volts. An excellent driver for "off-grid" or "lost-grid" radiant floor zone circulation. Because it is "constant-speed" a zone will not change characteristics, as batteries discharge. The built-in 3rd generation converter exceeds 96% efficiency. By distributing conversion among the zone circulators, instead of one central converter, system reliability is increased; a single failure does not stop all zones. Simplicity of wiring is also improved, as no central converter need be wired. Just fuse each zone pump branch (at the battery) and wire the battery through the thermostat and then to the zone pump.Product Manufacturer: Ivan labs, Inc.

    Frequently Asked Questions:

    What is the difference between the B     [battery] and PV [photovoltaic] versions?
    There are specific models that can be powered directly with a PV panel or a battery, or with an independent AC/DC power supply. If you're going to use an AC/DC power supply:
    • 14-17 volts DC; use a PV model El Sid Pump
    • 12 to 14 volts DC; you can use a B model El Sid Pump

    What is the pump's power usage?
    3.5 or 5 or 20 watts at 12 V, and 10 watts at 12 or 24 V.

    What is the SID pump's best use?
    The pumps are circulating, and are best for circulating water in a closed-loop system, such as heating or solar. As for anything else, their use is as unlimited as your imagination. Keep in mind they'll pump water, as well as antifreeze and various other chemicals.

    Here are just a couple of ideas:

    •     You can power them with a small RV deep-cycle 12-volt battery. Keep a trickle charger on the battery so that if the power goes out your pump will keep on running.

    • For solar system loops, the SID can be powered directly from a PV panel. The sun comes up, heat builds in the solar hot water panel and at the same time electricity is made in the PV panel. The pump slowly starts with the smallest amount of current and pushes the heated water to the storage tank. It's all too simple and eliminates all controllers, thermostats and sensors.

    What is the most common size?
    The SID10, because it's been around the longest. It's a good average size for radiant floor heat and domestic hot water solar.

    What would the 3.5 and 5 watt models be used for?
    Smaller systems, anything that needs less lift.

    Why are SID pumps more expensive?
    They're actually fairly inexpensive compared with other cheaper and shorter-lived pumps. They have, for instance, no brushes to change, and no moving or rubbing parts.
