SID Solar PV-Powered-Circulating Pumps Model SID-PV
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 couples the impeller and visibly drives it without any moving parts shafts or seals. As a result, of this it has a extremely long working maintenance free life with a very low Power consumption. These pumps are manufactured from bronze and stainless steel so the parts exposed to the fluid media are corrosion resistant.
The SID pumps have no seals which could leak and no bearings to fail or get hot, together with the fact it's high toque motor is a brushless high tech design. No brushes to spark, wear or need replacing.
The Perfect Pump for all Solar Hot water Heating Systems
The SID Pump is the perfect pump for all solar water heating systems. No mains power or batteries are required only low-voltage solar generated electricity, eternally available and pollution free. It requires
no electronic controllers and temperature sensors to be installed only if required. (It's that simple)
The Solar PV Panel powers the SID Pump that circulates the water from the solar collector to the cylinder/thermal store. when the sun rises in the morning the heat is collected by the solar heat collector and at the same time electricity is produced by the PV panel, the SID Pump slowly starts with the smallest amount of voltage from the PV panel. and then pumps heated water or glycol mix fluid from the solar collector the hot water cylinder/ thermal store. As daylight fades the SID Pump slows down and stops, at the same time the solar collector stops producing heat. This is a natural automatic trouble free control. Even in low daylight, over cast or cloudy conditions the drive motor produces enough power to start and run the pump with photovoltaic intelligent variable speed control.

Pump head:
Four screws shown, fix and hold the stainless steel fluid retaining plate in place. Also shown are four screw coming from the back of the pump body. when the 2W2 pump driver is in place, a total of eight screws hold and squeeze the fluid retaining plate in place. Note: there are is no drive shaft and of course no shaft-seals. The crown at the centre of the retaining plate houses the eight pole magnet, thus the rotating magnetic field in the 2W2 pump driver is coupled to the impeller which resides in the fluid
Easy to install:
The pump body is installed into a system using compression or solder type 15mm to 1/2" inch NPT female adapters, and then fit pump drive assembly to pump body. Any SID driver can be interchanged on the same pump body, which means that if the pump doesn't provide the the flow you require it's simple to change the driver to a smaller or larger driver within a couple of minutes.
