2. The pneumatic pump is reliable and low cost in flammable and explosive environments, such as the transportation of fuel, gunpowder and explosives, because: first, it is impossible to generate sparks after grounding; Second, there is no heat generated during operation, and the machine will not overheat. Third, the fluid will not overheat because the diaphragm pump has the smallest agitation to the fluid. 　　

Fifth, the safety of pneumatic ball valve is very high, so it is unnecessary to install other explosion-proof devices. It can be seen that its own safety, quality, and ensuring its safety during oil development and transportation are the reasons for installing pneumatic ball valves, which fully ensure the safety of oil and solve the problem of waste and loss caused by accidents.
