Semi Rotary Pump Fig. 4L

MAINTENANCE

– Before starting FIG.4L PUMP “ALETORIA” TYPE, we will mainly take into account that the assembly will be carried out in vertical position and that a suction valve will b located in the lower parto of the suction tuve that will ensure a continuous and correct priming of the pump.

– At the first start-up, it will be necessary to prime the pump by introducing wáter from the top, and then proceed with pumping. This is done making a ¼ turn back (suction) and anothert ¼ turn forward (discharge). After a few moments, it will need more effort to do this operation. It is a sign that the pump has already filled the pipe with wáter and is operational.

– When we detect that it loses pressure because it sucks air and lets a few drops of water lose through the Shaft (Nº 2), then we will have to carry out a revisión of the Packing (Nº9). We will carry out this revisión by first unscrewing the nut and washer by Shaft , then removing the Dowel (Nº7), together with its Handle (Nº6), we will continue with the Gland (Nº8) to fiinally remove one Bushing-press. We will be able to see if it is necessary to change the Packing or just complete the missing one.

– It will not be necessary to use any other type of maintenance except the use of the pump at least once every 15 days approximately to avoid its seizure

Our “Aletoria” pump is a rotary hydraulic pump that moves liquid from one place to another. The manual pump is a piece that can be manipulated with just one hand, to facilitate its use and the correct and safe extraction of the substance or liquid contained. To extract, simply apply the minimum effort necessary to create pressure inside the body or suction box of the pump by operating the lever and extract the necessary amount of product. Its main advantage is that it does not depend on an electrical network to carry out its work, so in the event of a lack of current or supply failure, it will continue to provide the service with full guarantees. Its applications are very diverse: in homes where access to the current or water is restricted or difficult (wells), to remove water from a flooded cavity, perform irrigation, emptying ponds or the domestic supply itself. The hand pump extracts water by pumping it from a lower level to the surface using human power. It is based on mechanical energy, so that since it is a rotary pump, it has a driving piece that rotates in one direction and then in the opposite direction when pumping, creating a suction effect inside the body that allows the entrance of the liquid inside creating a continuous current with the repetition of the movement. Its fix in case of breakage is easy, and it is possible for a user with basic mechanical knowledge to disassemble and repair it.
