How to select a centrifugal dewatering pump

Centrifugal pumps are versatile in their uses. These machines vary considerably in the technology that equips each one for a different set of jobs and circumstances. A careful choice is needed to ensure you optimally achieve your main dewatering objectives. Here are the key considerations to choose the right type of centrifugal pump for your application.

Efficiency

When users have to choose a surface pump, they usually opt for larger sizes on the basis that they can cover a multitude of jobs, but, in doing so, energy efficiency is often sacrificed. Developments in technology are helping to reduce fuel usage and operating costs. In recent years, newer types of pump have been introduced that are specifically designed to reduce fuel consumption at times of low load and cope with fluctuating application demands; without running up high-fuel costs or risking burnout.

Transportability

Dewatering pumps are now being developed to be smaller and lighter, as well as easier to move and transport both on and between work sites. Consequently, buyers should take time to ensure they select a pump that is suitable for use on multiple sites where the pumps might be working, and include built-in features that enhance movement and safety. Many larger pumps have integrated trailer options, as well as integrated lifting beams and/or forklift slots. Buyers should ask what options the manufacturer has added to aid the safe movement of the pump from site to site, or within the working location where it is needed.

Versatility

No two jobs are ever the same. For this reason, it is recommended when chooseing a dewatering pump, pick one that is suitable for multiple applications. Taking a look at the design of the pump’s components and how they work together should therefore be a priority. Subsequently, users should consider pumps that come with: A range of accessories to enhance performance for changing applications. A performance that covers multiple applications and offers different options. A modular design that enables upgrades or changes to the existing pump, without the need to replace it with a completely new one.

Durability

Pumps need to perform reliably in extreme environments. Therefore, it is important the selected pump has been tested and is capable of withstanding tough and changeable working conditions as soon as it is turned on. In addition, pumps shouldn’t get clogged up. If a pump becomes clogged, then it will reduce the flow of water being pumped. When clogging occurs, it will affect performance, and if allowed to continue for an extended period of time the pump could ultimately burn out. It’s not very often that users are pumping perfectly clean water, so some elements of clogging are a hazard of the task. To protect against problems, leading manufacturers are continually looking at the positioning of parts and specifically the inlet holes and passing areas. Before choosing a dewatering pump, users should ask what steps the manufacturer has taken to avoid clogging and guarantee consistent performance.

Serviceability

Downtime is lost time. When it comes to pumping fluids, any time lost for maintenance and repairs can be catastrophic. It is recommended to choose pumps with a combination of long-service intervals and simple service. Furthermore, as every second counts in terms of operational time, it is suggested to seek pumps that can be serviced in minutes, not hours, with easy access to all parts and consumables. Often, service needs to be completed remotely or at a job site, so the availability and simplicity of service pack is a major consideration when choosing a dewatering pump.
