The pump is buried within a mound of soil so it is very secure and resistant to theft or damage. Second, high performance. Third, easy maintenance. New piston cup seals can be fitted within moments while easily replaceable rubber flap seals may be cut from old tyre inner tube. The pump's light weight is also an advantage.
Many pumps are too heavy to be economically air- freighted.
An SWS Rower Pump, fully packed, weighs only 5 kilos which minimises the total cost. It is very important to remember that Rower Pumps are not intended for deep wells but are ideal for many situations which conventional deep well hand pumps are just not suited for.
