Manual of experiences ans tolerances in rope pump production
II. CHARACTERISTICS OF THE EQUIPMENT.
Rope pumps represent a simple and low cost technology, which is efficient at 50 meters
in depth and is categorized as technology appropriate for use in rural areas.
It is produced locally with materials that are easily obtained, such as: used tire rims,
injected plastic, hand-made ceramics, angle iron and rods used in construction,
polypropylene rope and PVC pipes.
Equipment repair and maintenance is carried out by the user, as its design allows full
mastery of the technology and does not require the use of unavailable or complex tools,
which allows the pump to remain active.
Handling this technology is very simple; the wheel is turned with the crank - even a
child can do it. On conclusion, the brake must be put on the wheel in order to
equilibrate the force of the water column. The pump is accessible to the rural population
as it can be acquired with their own economic resources. Its cost is between 3 and 10
times less than imported equipment.
With the use of the rope pump, there is an increase in the amount of water available with
less effort, and quality is maintained thus preventing diseases and improving the quality
of life.
II.a. WARNING.
The rope pump is in its installation, use and maintenance, an appropriate technology,
which does not require any special tools. However, its production includes high quality
parts.
THE ROPE PUMP at its current technological level:
- Does not have a rope with pieces of rubber acting as pistons!
- Does not have a crank with screwed in pipes and elbows!
- Does not have a siphon in the bottom of the well acting as a guide!
- Does not have a wheel made from wood or a bicycle wheel!
