How often is it necessary to carry out a maintenance process on your pump?

Maintenance of the pneumatic diaphragm pump is greatly simplified and can be carried out without compromising the continuity of its operation. The frequency of maintenance will depend on how your pump is being used and what the specific application is within your industry.

Considering this, most pneumatic diaphragm pumps must undergo a monthly maintenance process, always maintaining a preventive inspection protocol to avoid further damage.

What should be done when maintaining my pump?

First of all, we need to know what its basic components are and which parts can be damaged and replaced. The first step is to check your pump's diaphragm in order to identify possible deformations, cracks or holes that could indicate a wear process.

Another aspect to check is whether the pump tightening is correct. This is because the vibration of the equipment can cause some tightenings to become looser and impair the good functionality of your pump.

What is the wet side and dry side of a pneumatic diaphragm pump?

The pneumatic diaphragm pump is separated by its wet side and its dry side. The wet side is made up of parts that come into direct contact with the fluid being pumped, such as diaphragms and spheres.

The dry side refers to the parts that come into contact with compressed air that is used to operate the equipment, such as the air valve and the chamber.

Why are my parts getting damaged so quickly?

To know why your pump parts need frequent replacement, you need to check some factors, such as:

Chemical compatibility: this is one of the biggest problems that can harm the components of your pneumatic diaphragm pump. It is necessary to determine which fluid will be pumped and the chemical compatibility of the pump you are going to purchase. This pump is produced in different materials and some fluids that can cause faster degradation.

Problems with the pumping line: during your maintenance process it is necessary to check if there is any bend or obstruction in your pump line. It is also important to check whether the pump line size is too large for the application being performed.

Quality of pumped air: the air used in your pump must be clean and moisture-free air. Air quality directly affects the useful life of your pump, and for this reason it is very important to maintain adequate quality and pressure for its operation.

Fluid is leaking from my pump, now what?

If fluid leaks from the exhaust, it is necessary to disassemble the pump and go through a cleaning process. It is also important to check that the diaphragms are in good condition and replace them if necessary.

Why is my pump not pumping as expected?

The first step is to determine whether the pump used in your application is compatible with the expected flow rate. Depending on the case, it may be necessary to replace your equipment with a larger and more powerful pump.
