q: What data do I have to provide in order to get a quote for a pump?

- Fluid and its characteristics: pH, percentage of solids, temperature, specific gravity, viscosity and density.
- Flow
- TDH
- Calculation elements for NPSH available.

 
q: Why is technical data necessary for a pump to be offered for a process?

It is very important to have the complete data necessary for an application, since in the design of the selection of a pump it is handled as an exact science and not having or assuming a data can cause problems for the client during the process, such as high consumption of spare parts and maintenance, high energy consumption, lack of flow or low dynamic load. Dynapro does not work on direct replacement of pumps, since we could drag previous selection problems and only with complete and correct data can we reach the solution of root problems.

 
q: Is it important to know the process fluid?

Yes, with the fluid data we can propose the best material that suits the process and thus prolong the life of your pump.

 
 
q: Can you propose a direct replacement for pumps of another brand?

Yes, in addition to our own pump lines, we can offer 100% interchangeable parts with other OEM brands. For more information, contact one of our service engineers, we are sure we can give you the help you need.

 
q: Do you sell pumps from a brand other than Dynapro?

We manufacture our own pumps so we only sell Dynapro pumps.

 
q: Why should I switch my parts to Dynapro? I already have the best brands working with me?

We handle spare parts, 100% interchangeable with OEMs because the same plants that supply our parts are the same as those that have produced for other OEMs. Our advantage is in the direct sale of these high-quality spare parts. In addition to having a warehouse for spare parts in both Mexico and Canada, we also have distributors throughout North America. Our stock is readily available for our clients. On request, we dedicate stock to your critical applications.

 
q: I prefer to keep the gasket sealed. The mechanical seal will break easily.

The mechanical seals that Dynapro handles are of high quality and robust, actually 90% of the failures in mechanical seals are due to operation and maintenance problems, with our advice we are sure your seals can achieve a long useful life and that they are a solution efficient and not a problem.

 
q: Does Dynapro sell motors without a pump?

No. We manufacture pumps so motors are only priced with one pump.

 
q: Do all pumps come with a motor?

Our pumps can be quoted with or without motor, it depends on the client's request.

 
q: Do you sell non-Dynapro pump parts?

Some of our pumps are 100% interchangeable with other brands, so depending on the pump model, we can quote the replacement parts.

 
q: Is the Dynapro SRL Pump dimensionally the same as our Interchangeable Denver SRL Pump?

No. They’re not dimensionally the same. Although, the hydraulic of the pumps are identical, which means their performance is exactly the same.

 
q: What is the difference in your standard materials for the Dynapro SRL Pump and our Interchangeable Denver SRL Pump?

The standard material for the Interchangeable Denver SRL is carbon steel for the shaft sleeve, lantern ring, and packing gland, whereas the standard material for the Dynapro SRL is 420SS for the shaft sleeve, and 316SS for the lantern ring & packing gland. This helps us start with a higher quality construction standard material, increasing the wear-life of your pumps.

 
q: Can we change our sealing to a mechanical seal while having a high percentage of solids in the slurry?

Yes, we can analyze your process and fluid to offer the appropriate solution with the mechanical seal , which can be dry, semi dry or handle an API plan depending on the case that applies.

 
q: Do Dynapro mechanical seals have the same durability?

Yes, our mechanical seals are of high quality and can give a high durability equal to or greater than the seals you know.

 
q: I need to add mobility to a pump for a new process.

It is extremely important to know the points where the pump is to be operated in order to make the proper selection between these different points. It is not advisable to operate a pump at different points without making sure you are using it with the correct parameters. Dynapro has self-priming and internal combustion engine pump options as well as the appropriate engineering equipment to determine if your application is suitable for these pumps.

 
q: Do your Liners fit? Could we have a fitting problem? It happens often with other providers.

Our liners are 100% compatible and hunt correctly with OEM (Original Equipment Manufacturer) brands, however, it is necessary to determine if the bombs are correctly assembled. It is common to see in the field that casings or covers that fit the screws are changed. With this, the liners would no longer be correct for those new pieces. In the case of marketers, normally their liners do not come from the OEM factory like ours, so it is common to see fit problems.

 
 
q: The pump is not giving the required flow.

The most important factor is determining whether the pump has been correctly selected for your application. If the selection is adequate, we must analyze the operating and maintenance conditions that usually contribute to the detriment of the flow required in a system. If you have flow problems with our - or any - pumping equipment, contact our engineers and we will help you determine where the problem is.

 
q: My pump is cavitating. What could be happening?

There are many reasons why a pump may be cavitating, from poor purge or prime to poor NPSH. In order to solve this problem, it is important to know the conditions under which the equipment is working. The problem of cavitation in a pump is a very extensive and recurring topic. If you need to solve a cavitation problem, you can contact our service engineers to study your case.

 
q: How can I increase the flow of my pump without changing the equipment?

Depending on the desired increase or decrease, you can choose from a change in speed, a larger or smaller impeller diameter, to a motor change. With an adequate engineering analysis, we can determine which is the most optimal and profitable way to make these modifications.

 
q: What can we do to make a pump equipment last longer?

There are many factors that influence the lifespan of pumping equipment. A correct selection, a correct operation and a correct maintenance. Depending on the application, some factors that tend to have an important influence on the duration of the equipment are the factors of speed, materials, and design. Our engineers previously study the application, looking for the best operating point to be able to provide the equipment with a long-lasting option. A simple speed factor can give us the opportunity to provide a choice of equipment that will make its parts last 3 times longer.

 
q: Seal water is diluting my process. How can I solve that?

We can considerably reduce the dilution by seal water, using mechanical seals, at Dynapro we handle dry and semi-dry seals, which can be the option to reduce the dilution of the process from 99 to 100%

 
q: Engine bearings have to be replaced very often. For what is this?

Generally, bearing failures are related to installation, inadequate lubrication or excessive vibrations in the equipment.

 
q: The motor is always working in over-amperage. For what is this?

If this occurs at the beginning of the equipment use, it is probably due to an incorrect selection regarding the dynamic load. If the over-amperage occurs after it has been operating correctly, it is possible that some change in dynamic load has arisen. If not, it may be due to fouling in the discharge pipes or physical and chemical changes in the fluid.

 
q: We are replacing bushings too often. How can it be solved?

Bushing problems are often related to equipment lubrication. To solve this, it is necessary to check that a correct lubrication is being applied. Also, it is important to determine if the correct bushing is being used for the equipment.

q:What is the net positive suction head (NPSH) of a pump?

The net positive suction head (NPSH) is the difference between the total head and the vapor pressure head.
Net Positive Suction Head (NPSH) is a term used in engineering to define the head available to a pump at the suction point. The NPSH available to a pump is the difference between the total head and the vapor pressure head. The total head is made up of the static head, the frictional head, and the velocity head. The pressure that the vapor in the liquid exerts is known as the vapor pressure head. If the vapor pressure is greater than the atmospheric pressure, then the vapor pressure head will be negative.
The NPSH required by a pump is the minimum NPSH available to the pump at the operating point. The operating point is the point at which the pump is running at its rated speed and producing its rated flow. If the NPSH available at the operating point is less than the NPSH required by the pump, then the pump will cavitate. Cavitation is the formation and collapse of vapor bubbles in a liquid. When the vapor bubbles collapse, they create a shock wave that can damage the pump.
There are three factors that affect the NPSH available to a pump: the pump design, the operating conditions, and the characteristics of the liquid. The pump design is the most important factor. The NPSH available to a pump is a function of the pump's design and the characteristics of the liquid. The operating conditions of a pump change the total head and the vapor pressure head, which in turn changes the NPSH. The liquid's properties change the vapor pressure head, which in turn changes the NPSH that a pump can use.
A pump's NPSH can be raised by either raising the total head or lowering the vapor pressure head. The total head can be increased by increasing the static head, the frictional head, or the velocity head. The vapor pressure head can be decreased by increasing the atmospheric pressure or by decreasing the vapor pressure. The NPSH available to a pump can also be increased by using a pump with a higher design NPSH.
To lower the NPSH a pump needs, you can either lower the total head or raise the vapor pressure head. Decreases in the static head, frictional head, or velocity head can all reduce the total head. The vapor pressure head can be increased by decreasing the atmospheric pressure or by increasing the vapor pressure. The NPSH required by a pump can also be decreased by using a pump with a lower design NPSH.
The NPSH available to a pump and the NPSH required by a pump are both important factors in the selection of a pump. The NPSH available to a pump should be greater than the NPSH required by the pump. If the NPSH available to a pump is less than the NPSH required by the pump, then the pump will cavitate.

Air pockets in the pipe: If there are air pockets in the pipe, the air can cause a vacuum and prevent the liquid from flowing properly. 4. Poor installation: If the piping is not installed correctly, it can lead to improper suction. 5. Poor maintenance: If the piping is not properly maintained, it can become blocked or corroded, which can also lead to improper suction. Video: Click Here
