What to Look for When Buying Centrifugal Pumps for Sale
Historically, pumps were used for irrigation and drainage. However, they have found their place in many facets of industry, which in itself, makes it difficult for one to make a choice when there are many different types of centrifugal pumps for sale. Pumps may operate on the same working principle but purchasing the wrong-sized pump can land up costing a lot in the long run due to extensive maintenance repairs or a replacement of the entire operating system. We at Prochem Chemical Pump Manufacturers will ensure that the centrifugal pumps for sale through us suit your intended application, thereby ensuring the longevity of the pump and system.
Matching the Required Use to the Right for Sale
There are a few things to consider when matching a centrifugal pump to a system in which the flow rates, the viscosity of the fluid being pumped, generating power, and the energy-efficiency of the pump have to be factored in. Before buying any centrifugal pumps for sale, make sure that the system design of the pump is what it needs to be used for. In manufacturing processes, the production times are vital and selecting the right centrifugal pumps for sale the first time around is crucially important.
Know the Pump’s Capabilities
Understanding the pump’s capabilities under certain operating conditions gives one options when it comes to the selection process.
- System Design
The design and size of the pump determine at what rate the liquid needs to be delivered by the pump, the total pressure that the pump needs to generate in order to deliver the flow rates required, and the duty point to obtain the impeller size and horsepower of the motor. When sizing, the motor current and future performance must be considered to make sure that the motor is the correct size. Deviating from the parameters of the pump’s design can cause excessive noise, circulation problems, vibrations, and possibly cavitation.
- Performance Curve
The performance curve of a pump isn’t a measure of how well the pump has done – it indicates how the pump performs in regard to water pressure (head) and flow. The curve is defined by a specific operating speed as well as inlet and outlet diameters, which are affected by the size of the impellers. Adjusting the size of the impellers to meet specific operating conditions changes the performance curve. The performance curve will also indicate the efficiency of the pump.
- Duty Point
The duty point or pump-operating point is the intersection between the system’s characteristics and the performance curve. As there is a balance between what the system demands and what the pump can deliver, the pump will always operate where the system and curves intersect.
Externally and internally, the type of centrifugal pump selected must be able to handle both constant and cyclical operations and be made from non-corrosive materials that are extremely durable, are resistant to fatigue, and have high flexural strength.
