Like most other developing countries, mining remains the soul of Zimbabwe's economy. The drilling and mining equipment operation is based on hydraulics. The steering system, the hoisting, dumping, hauling and hydraulics systems constitutes approximately 80% of the mechanical build-up of these equipment. In a mining setup, lubrication of the hydraulic system for these equipment is extremely critical. Breakdown of these machines may lead to the need of refilling of the hydraulic tanks hence a convenient mobile pumping system has become the crying need for mining industries. Literature was carried out on already existing designs. Information obtained includes, materials used, methods used, selected operating mechanisms, history of designs from various sources. Information pertaining to the parts regarding price, rating, availability, functions, performance and alternatives was obtained. In the design process, the reciprocating aspect of the slider crank was designed basing on the discharge flow required. An experiment was carried out to determine the flowrate. A diaphragm was added to the piston to ensure the separation of the oil being pumped and the actuator(pneumatics). Pneumatics offers a more flexible safer alternative to electric motors. Air is clean and will not harm to the environment in case of any leaks. There is also reduced risk of ignition as there will be no magnetic fields or sparks associated with the system. The von Mises stresses and deflections were done using Solidworks and they were in range and the weakest point was determined. The bending stresses were performed using SkyCiv Software. Design specifications and drawings were developed for the machine. Specifications for the manufacture and assembly of the mobile reciprocating pumping system was also provided. House of quality was carried out focusing on reduction of cost through minimizing the number of parts retaining its function. Material for components were selected.
