The PV powered Pump, SOLARRAM^TM

BSRsolar's SOLARRAM^TM is designed for deep-hole pumping from 10 meters down to 50 meters. The prime mover, a PV powered, DC, 250W centrifugal pump with a wire-to-water efficiency of around 40% drives the suction ram, the in-the-hole equipment which has an efficiency of about 85%. With no moving parts in the borehole except for two seat valves, the suction ram is rugged and highly reliable.

The SOLARRAM^TM pumping system has distinct and unique features which sets it favorably apart from competitive products.

	A multiport fountain structure allows the deployment of additional prime movers, i.e., the solar-thermal pump SUNPULSETM water, a gasoline engine or hand actuator. Thus with a limited financial investment, peak requirements during crop season are met as well as ongoing fresh water supply secured, day and night.
	The technology is proven. The simple design and the choice of material assure operational dependability at very low maintenance cost and negligible failure rate.
	Constant power rating due to self-adapting delivery to head allows the use of the same SOLARRAMTM configuration for any depth, without necessitating any adjustments or adaptations.
	The centrifugal pump can be mounted apart from the actual well as it is linked to the suction ram only by two water hoses thus avoiding an expensive platform above the borehole or well and minimizing the risk of water contamination.

The following performance data are based on average daily sun radiation of 6 kWh/square meter. Actual pumping output will, however, vary with tilt angle, seasonal weather, dust occurrence and other conditions.
