Impeller

Highly efficient and dynamically balanced with fine ceramic bearing for smooth ultra quiet operation.

Construction

Wetted parts are food grade stainless steel, food grade thermoplastic (Viton), carbon and ceramic for superior reliability and corrosion resistance.

Dry-running protection

Drive circuitry can detect no or little liquid in pump chamber and will stop the pump to prevent damage, pump is then restarted manually by disconnecting and reconnecting it to the power supply.

Over voltage protection

When the voltage over 28V, the pump will auto-protect and shut off own power supply, when the voltage falls below 28V, the pump will restart automatically.

Over load protection function

This means that when the current is over the rated current, such as can arise if the impeller is stuck due to debris. The pump will automatically stop to prevent damage, and will restart when the current falls again.

PV operated

For solar system loops, the Sidek pump 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 liminates all controllers, thermostats and sensors.

Soft start-up

The Sidek DC pump has a soft start-up feature which reduces high in-rush current. When the photovoltaic panel provides sufficient power, the pump goes through the alignment phase by turning the rotor into the position required for start-up. The processor then waits until the capacitor is sufficiently charged. This enables a start-up with minimal power (less than two watt). Cycling due to unsuccessful attempts is minimized. Even after prolonged shutdown, the pump will start reliably.

Over-temperature safety device

The Sidek DC pump comes with an integrated over-temperature safety device which shuts off the pump electronics when reaching temperature over 110°C (230°F). When the temperature of the pumped fluid is below 95°C (203°F) the pump will function normally. The temperature of the electronic components is influenced by the temperature of the pumped media as well as by the speed setting. After reaching a critical temperature 95°C (203°F) the pump will lower its speed automatically in order to avoid a total shutdown.

Maximum Power Point (MPP) tracking

Every three seconds the processor will modify its operating point on the voltage-current curve of the PV panel to find the point of maximum performance. At this point, the pump achieves the maximum rpm and therefore the maximum performance. There is no need for a separate performance device. The eco solar pump will always find its best operating point under any given light and temperature conditions. By employing MPP tracking every three seconds, the Sidek pumps always automatically achieve maximum erformance at any given insolation.

Mounting

The Product comes with 2 mount-brakets (Wedges) included in the packaging which allows for a tight mount on cylindrical water heater cases.

The box must be mounted in the vertical position using the mounting holes on either side of the case. The pump and controller must be mounted below the water outlet level on the hot water tank. This keeps the pump flooded should the system become depressurized.

Photovoltaic Operation

The recommended photovoltaic connection is via a battery back up system. The pump and controller are powered via the battery and the photovoltaic panels maintain the charge of the battery.
