Like standard pumps, high-pressure pumps come in various specifications and sizes. Thus, when choosing a high-pressure pump, you can't rely on the brand alone to determine whether a pump is good or not.
Furthermore, choosing the wrong high-pressure pump will result in various issues, such as:
- Poor performance
- High energy costs
- Frequent malfunctions
- Premature pump replacement
Hence, you must be cautious when choosing a high-pressure pump to avoid the above issues. However, there are several factors you should consider before purchasing a high-pressure pump. These factors ensure that you pick a pump suitable for its intended work environment and performance requirements.
Here are two factors to consider before buying a high-pressure pump.
1. Rate of Flow and Pressure
High-pressure pump manufacturers usually provide the rate of flow and pressure ratings for their pumps. But it would help if you calculated the flow rate and pressure you need a high-pressure pump to provide before buying one.
Flow rate refers to the volume of water/fluid a high-pressure pump can supply in a given period. The ideal flow rate of the high-pressure pump you need depends on the water demand. For instance, if you intend to use the high-pressure pump in a car wash, consider how much water you will need at any given moment from the pump.
Pressure refers to the operating force within the high-pressure pump. The amount of pressure a high-pressure pump provides depends on the flow rate. Typically, the higher the flow rate a high-pressure pump has, the more pressure it can provide.
Thus, before you buy a high-pressure pump, have a pump technician or hydraulics professional calculate the rate of flow and pressure you need.
2. Water/Fluid Properties
The type and quality of water you use also determine the kind of high-pressure pump you need.
Various high-pressure pump components are sensitive to the type of water running through the pump. As a result, high-pressure pump manufacturers always indicate the type of water/fluid their pumps should handle.
For instance, if you intend to pump alkaline or acidic water, you should opt for a high-pressure pump designed for such fluids. If you use a standard high-pressure pump with acidic or alkaline fluids, the pump will corrode. Thus, you will encounter frequent repairs and a shorter pump life.
When shopping for high-pressure pumps, ensure you understand the nature of the fluids you want to pump. If the fluids are acidic or alkaline, ensure the high-pressure pump you buy can handle fluids with high or low pH values.
