Laing D5 Ecocirc Solar DC Pumps

The D5 Solar pump can be used for most circulation pump applications without connection to the power grid. Highly efficient, the D5 Solar can be connected directly to a photovoltaic panel. It is characterized by its small size, high efficiency, extremely low power consumption and its over temperature safety shut off device. The shaftless spherical motor technology provides maintenance free and quiet service life. This pump is also perfect for single family home thermal solar systems or any circulation pump application where conventional power is not available.

The first DC spherical motor pump for direct connection to photovoltaic panels with automatic performance optimization using Maximum Power Point (MPP) tracking will vary its flow and power consumption based on the available solar energy.

#1 Q:   Laing D5 Ecocirc Solar DC Pump has 1/2 inlet and outlet. Most water heater systems have 3/4 piping. Will it negatively affect the flow by reducing the piping at the connection to this pump? Should I look for a pump with 3/4 inlets and outlets?
A:   You should select the pump based on the flow and head required for your system. The inlet/outlet size on pumps is typically based on the expected flow rates. Selecting a pump with a smaller connection might be an indication that you are choosing a pump that is too small for your system... Again, it all comes down to what kind of flow and head is required for your setup.

#3 Q:   Were temporarily removing panels during renovations and do we need to power off pump? Well be using water heater w/o panels for a month or so.
A:   You should power down and store the pump. Running dry will destroy the integrity of the shaft seal.

#4 Q:   Hi; on a drain back solar system how high can i expect the pump to the water up and if nessary could i use two pumps in series in order to pump high enough. thank you peter
A:   The expectation for lift on that pump would be the feet of head rating which is about 6-8 feet.

#5 Q:   can I just purchase the pump motor without the brass base for the D5Solar/710B?
A:   They are unavailable as replacement motors, the whole pump must be purchased.

       Asked on 2013-11-09 by mark
#6 Q:   Is the pump damaged by backflow from a modestly sized drainback system? Is there resistance in the pump to water flowing by gravity backwards through the pump?
A:   Should cause no ill effect, though it will provide some resistance as it is designed for optimum flow in one direction.
