Definitions

  • This descriptive report refers to a PNEUMATIC FLUID AND GAS PUMP, which has been developed specifically for use in the transfer of flammable, explosive or inert gases, and in liquid form from one location to another and may be used in more varied industrial segments, especially those that require strict and precise control of the dosage of the products to be pumped with more pressure.
  • It is a mechanical device, driven by compressed air, whose purpose is to enable the transfer of gases of various types, flammable or not, in the liquid state and by pumping, from a certain position of lower pressure to another distant position with greater pressure and precision.
  • the fundamental objective of the PNEUMATIC FLUID AND GAS PUMP, now proposed, is the filling operation, that is, the precise dosing, by weight or volume, of quantities of products of various types, flammable or not, in equipment. or packaging within small and acceptable tolerances.

  • An innovative feature is the fact that there is a single concentric axis for the two cylinders, and at the ends of said axis are arranged two pistons, one for the compressed air cylinder and one for the cylinder of the cylinder. pumped product, which are fully embedded in the equipment, thus avoiding any contamination by abrasive or corrosive agents present in the environment.
  • This concentric shaft because it is unique, does not require the use of movable or fixed joints, which cause undesirable movements, both longitudinally and lengthwise, avoiding the use of heavy and sturdy bases, built to give stability to the equipment.
  • Another innovative feature is the system that provides the alternation of the direction of the piston back and forth movements, which are determined by two small limit valves, carefully installed in the engine cylinder and actuated by the piston itself, when it reaches the predicted maximum displacement within the cylinder.
  • Another feature to highlight is its drive which is made by means of a small shaft - which is fully embedded and protected inside the cylinder cover, sealed properly to the operating pressure of compressed air, - which transmits the impulse given by plunger to the limit switch, which in turn drives a five-way pneumatic valve, thereby reversing the movement of the shaft and hence the operation of the bomb.
  • This saves the end-of-stroke valve from undesirable spring forces on it and protects itself from abrasive and corrosive elements present in the environment.
  • This pump is equipped with high performance sealing seals, which were developed specifically for this purpose, since they bring together in the same set two systems, the Oring ring and the axial type sealing material compatible with the product, thus ensuring the perfect sealing, both internally and externally.

This operation is guaranteed by four specially designed check valves (11), which are arranged in two and two, opposite and properly embedded in the moved cylinder heads (2), allowing the product flow to always have the same direction at the pump outlet.
