Design Specifications


  • Pumps are fitted to ECDRIVE maintenance-free brushless DC motors without integrated electronics.
  • They should be powered by solar arrays configured to provide the input voltage required and sized at approx 120% of the rated motor power.
  • Speed: 900-3300 rpm
  • Insulation Class: F
  • Enclosure Class: IPX4
  • Integrated data logging of all relevant technical parameters, flow, and fuel cost savings easily accessible via pump scanner smartphone app.
  • Advanced configuration options for daily flow rate, constant and min/max pressure, level, and flow rate sensing.
  • Sensor inputs for dry run protection, tank switch, water metering, pressure, and level sensing.
  • Switch output for external devices (e.g chlorine dosing units, irrigation valves, etc).
  • Integrated SunSensor for extended pump lifetime.
  • Optional remote control functionality using the PS Communicator and pump manager service.
  • Integrated MPPT (Maximum Power Point Tracking) for maximum solar energy conversion efficiency.
  • Protection against reverse polarity, overload, and over-temperature.
Operating conditions
  • Pumped Liquid: Thin, clean, chemically non-aggressive liquids without solids and fibers.
  • Maximum Liquid Temperature: +700 C
  • Ambient Temperature: -300C - +500 C
  • Suction Head: Max 6m (depending on operating parameters, refer to COMPASS software sizing)

    I like the approach to distribute kits that also include underwear to school girls. Reading through the document, a couple of questions came up:
    1) It would be interesting to understand what locally sourced agricultural byproduct is used to make the napkins. Are they referring to the absorbent material?
    2) Not sure what makes these products eco-friendly. Is tit the use of the agricultural byproduct?
    3) I’m very surprised that these products are manufactured in Kenya, I wasn’t aware that manufacturing capabilities for such sophisticated products were available in the region. Especially the Safi pad would require quite complex equipment, e.g. to apply the colored sides and the high resolution embossing. They look to me more like products produced in Asia. Could it be that “manufacturing” in this context only refers to packaging, i.e. they source bulk napkins from Asia and package them in Kenya?
    4) It would be interesting to understand the financials that enable to sell them at low cost (i.e. 30% less than the average product cost). Is low cost achieved through subsidies or donations? Or is their production cost low enough to achieve low cost to the consumer? The design with wings indicates significant design waste in production, which normally increases the cost. Also the construction seems to be quite complex, with several raw materials (rolled goods like cover, barrier etc.) being used. Most of these raw materials are not produced in Africa, in particular the cover materials.
