FOR THE POWER PERFORMANCES The hydraulic pumps have an unbeatable power / weight/ dimension ratio, example an hydraulic motor with power of 15 kW have a weight of only 4 kg and the dimension of a beer crate, which other type of motor either electric, gasoline, pneumatic or other can give such concentrated power. This gives to the hydraulic pumps compactness, lightness, easy handling and unmatched performances. In case of emergencies and calamities (like floods) where are necessary efficiency, high power, speed, capacity of operate in all situations then no other pumping system is better then hydraulic pumps, guarantee !!!
FOR THE SAFETY Absence of electricity is an implicit assurance of safety as it is impossible to cause electric shocks, a man can work in all safety with the feet in the same water where the hydraulic pump is submerged and pumping , this will not be allowed by law and can be fatal when working with electric pumps, contacts or accidental rupture of the electric power cable can cause accidents and death.
FOR THE POSSIBILITY TO RUN DRY AND FOR MANY OPERATIONAL ADVANTAGES A hydraulic pump can run dry without limitation and as long as needed, most the pumps either electric or with engine cannot run dry !!! This is an important point that avoids potential equipment expensive failures, beside this many are the advantages that are given by the hydraulic functioning, the submersible pumps have not problem of priming, they pump as they touch the water, so it is possible to place the pumps is difficult access points where the traditional self priming pumps with engines cannot stay and operate or will simply sink in the mud (example on ponds or from a high position to the water level that will prevent suction etc). So when are needed fast actions, practicality, high power , care free operations, rusticity to afford any hard use the hydraulic pumps have no rivals.
FOR THE ROBUSTNESS AND FOR THE LONG OPERATIVE LIFE For sure there are no other pumps that can stand impacts and abuses as the hydraulic pumps can !! Pumps are really strong and are made to resist to the more heavy duty use. The hydraulic functioning is assurance of “self lubrication”, so the motor is constantly lubricated by the oil , this united to the simplicity of the hydraulic motor gives lower number of parts subject to ruptures and wear, and a working longevity that is impossible to they type of pumps. In case of an accidental block of the impellers rotation, due to the entrance in the pumping chamber a solid object or a clog, nothing will happen to the hydraulic water pump and nothing will “burn”, the oil will be simply bypassed to return by the relief valve. Other pump will have serious damages in such conditions.
FOR THE VERSATILITY The hydraulic pumps are really versatile as they can work powered by power packs and by the hydraulic circuits of excavators, back hoe loaders, trucks, mining machinery, tractors, boats and all working machinery equipped with a sufficient hydraulic circuit, no other type of pump can offer this advantage, this versatility means to have cheapvhydraulic power anywhere anytime simply exploiting the hydraulics of machines.
FOR THE EASY MAINTENANCE The maintenance needed is minimal and simple , pumps are made with many parts that can be sourced on the market at low price. The simplicity of the hydraulic motors and associated components, the absence of the many complicate parts that are on the electric or self priming pumps make the maintenance easy and possible for any mechanic and without the need special tools or equipment.
FOR THE ECONOMY
For all the above advantages, for the economy of purchase, the economy of running, the economy on maintenance costs, the long operative life etc all this guarantee consistent cuts of costs and the maximum economy.
