7 II.- EQUIPMENT CHARACTERISTICS - Appropriate technology equipment effective at a depth of 50 meters. - Produced with accessible materials. - Maintenance and repair do not require expertise and complex tools. - Easy to handle. - Easyto install. - Its relatively low cost makes it accesible to the rural population. - Preserves the quality of the water and the population s health.

9 I.- PRESENTATION This manual of technical drawings is part of the rope pump technology transference programme. It has as its goal to show in a clear and detailed manner the essentials of each component of this useful hand pump. In addition to the current manual, the programme prepared manuals of the family well rope pump and the community well rope pump. Their respective front page is shown in the back of this manual. Each component is presented here with its corresponding measures, a list of all the necessary production materials, and complementary technical information. In March 1996, the Governments of Nicaragua and Switzerland - through COSUDE - signed a new three-year bilateral cooperation agreement by wtiich the INAA-COSUDE programme activities are to continue for the period. Within the framework of this agreement, the transference of rope pump technology seeks to promote rope pump production at the regional and international levels. The Technology Transfer Division of the Rope Pump Company will be in charge of carrying out the aforementioned production activities. The Division is provided technical consultancy services through the Dutch Ecumenic Development Cooperation Organization known as Servicio Ultramar~ ( Overseas Services ) or DOG (for Dienst Over de Grenzen ). This is an easy-to-understand document and is aimed at future producers, cooperation organizations working in the field of water and sanitation, and other persons interested in the rope pump technology. Together with the rope pump production photomanual and the document Experiences and Tolerances, this manual provides all the information necessary to carry out technology transference activities at the international level. This Manual has been prepared by the Technology Transfer Division of the Rope Pump Company. It can be freely reproduced. Los Cedros, Province of Managua, Nicaragua. 4 August 1997.

13 A- PISTONS AND ROPE Piston diameter is determined by the type of pipe to be used and the well s depth. Pistons should be made of injected polypropylene or polyethylene. Neither rubber nor wood are recommended. - Five different piston sizes are used. - The rope s Ienght, diameter and amount of pistons are determined by the well s depth. Length and diameter variations for both the pistons and the rope Deoth (meters) Component part Unit Piston nominal diameter inches 1 3/4 1,4 % Rope length Meters Rope diameter inches 1/8 1/8 1/8 1/4 Amount of pistons unit Two-inch (0-3.5 meters) and I 1,4~inch (3.5-5 meters) pistons are used in wells wt,ich are not too deep or when motor pumps are used. - Deep wells (37-50 meters) use ½ inch pistons with Rim # 16, a double crank system, and wooden bearings. These pumps are installed as on drilled wells in order to increase the contact between the pulley wheel and the rope.

21 B.1. GUIDE BOX INTERNAL PIECE - The guide box internal piece is made up of five components: - The entrance pipe, pumping pipe and protector are made of PVC pipe. Diameter is determined by well depth. - The ceramic piece and the base part do not vary regardless of well depth. Measurement variations for the guide box internal piece Drawing No Component Depth (meters) Unit Ceramic piece Base diameter Inches I 4 - Entrance pipe diameter Pumping pipe diameter Diam. of pumping pipe_protector Inches 1 1/2 1 1 Inches Inches 1 1 3/4 3/4 1/2 1/2 PVC pipes may vary in diameter depending on the manufacturer. However, it is recommended that they correspond in diameter to the pistons nominal diameter. This prevents water leaks and increases pumping efficiency. The ceramic piece may be replaced by an electric insulator or a bottle, provided that the rope does not wear away.
