Outra característica a destacar é seu acionamento que é feito por meio de um pequeno eixo - o qual está totalmente embutido e protegido, dentro da tampa do cilindro, dotado de vedação adequada à pressão de operação do ar comprimido, - que transmite o impulso dado pelo êmbolo à chave de fim de curso, que por sua vez, aciona uma válvula pneumática de cinco vias, invertendo assim o movimento do eixo e, consequentemente, a operação da bomba. Isto faz com que a válvula de fim de curso seja poupada de esforços indesejáveis de molas sobre ela, além de se proteger de elementos abrasivos e corrosivos presentes no meio ambiente. 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.

Tais cilindros são projetados para resistir pressões de trabalho de projeto, fabricados em aço e com revestimento de cromo, ou outros materiais, em função dos produtos a serem bombeados. As tampas (12) que vedam o cilindro motor (1 ), tem a função estrutural por resistir às pressões internas, podendo ser constituídas em alumínio, aço o outro material adequado. Nelas são fixadas as vedações, as hastes de fechamento e o dispositivo suporte das válvulas de fim de curso. As shown in the figures, the PNEUMATIC FLUID AND GAS PUMP, now proposed, consists basically of two opposing cylinders, of different sizes or not, where one receives the compressed air, called force or motor cylinder (1), and another, called a moved cylinder (2), receives and transfers the product to be pumped. Such cylinders are designed to withstand design working pressures made of steel and chrome plated or other materials depending on the products to be pumped. The caps (12) that seal the drive cylinder (1) have the structural function of resisting internal pressures and may be made of aluminum, steel or other suitable material. The seals, the closing rods and the support device of the limit valves are fixed to them.
As tampas (13) têm a finalidade de fechar o do cilindro movido (2), e alojar as válvulas de retenção (1 1 ) responsáveis pela dupla ação da bomba.  The caps (13) are for closing the driven cylinder (2) and housing the check valves (11) responsible for the double action of the pump.
A relação entre as áreas do cilindro motor (1 ) e do movido (2) determinam a relação de pressão entre o ar comprimido, fixado na entrada, por meio de um dispositivo regulador de pressão, e a saída do produto bombeado, em proporção estabelecida em projeto específico, e que passa ser característica técnica do equipamento, como por exemplo, 2: 1 ; 3: 1 ; 5: 1 , ou qualquer outra necessária ao processo industrial onde a dita bomba for operar.  The ratio between the motor (1) and the driven (2) cylinder areas determines the pressure relationship between the compressed air, fixed at the inlet, by means of a pressure regulating device, and the output of the pumped product, in a proportion established. in a specific project, which becomes a technical characteristic of the equipment, such as 2: 1; 3: 1; 5: 1, or any other necessary to the industrial process where said pump is to operate.
Um único eixo concêntrico (3) para os dois cilindros, sendo que, em uma das extremidades está o êmbolo (4) do cilindro de ar comprimido (1 ) e na outra o êmbolo (5) do cilindro do produto bombeado, os quais ficam totalmente embutidos, evitando a contaminação por agentes abrasivos ou corrosivos presentes no meio ambiente. Este eixo concêntrico, por ser único, dispensa o uso de junções, móveis ou fixas, que causam movimentos indesejáveis, tanto no sentido longitudinal quanto no comprimento do eixo, dispensando as bases pesadas e resistentes, construídas para dar estabilidade ao equipamento. A single concentric shaft (3) for the two cylinders, at one end of which is the piston (4) of the compressed air cylinder (1) and at the other the piston (5) of the pumped product cylinder, which are fully embedded, avoiding 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, eliminating heavy and sturdy bases, built to give stability to the equipment.

This drive is made by means of a small shaft (7), embedded and protected, inside the cylinder cover and provided with a seal (8) suitable to the operating pressure of the compressed air, which transmits the thrust given by the piston to the end switch. This, in turn, drives a five-way pneumatic valve (9), thus reversing the movement of the shaft and, consequently, the operation of the pump. This operation causes the limit valve to be spared from undesirable stresses.

O alto desempenho desta bomba deve-se ao duplo estágio que debita o produto tanto na ida como na volta. Esta operação é garantida por quatro válvulas de retenção (1 1 ), especialmente projetadas para esta finalidade, as quais estão dispostas em duas e duas, contrapostas e devidamente embutidas nas cabeças do cilindro movido (2), permitindo que o fluxo do produto sempre tenha a mesma direção na saída da bomba. The internal sealing of this pump is made by means of high performance sealing seals (10), which join two systems, the Oring ring and the axial type seal, which guarantee the perfect sealing, both internally and externally. The high performance of this pump is due to the double stage that debits the product both on and off.
