May 6, 2021

The applications for dewatering pumps vary widely. Therefore, it’s essential when choosing a dewatering pump portfolio that users choose equipment that is versatile, while remaining productive, safe and trouble-free.

Here are five key considerations you should focus on when choosing a dewatering pumps:

1. 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.

2. Size and movement

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.

3. 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.

4. 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.

5. Ease of service

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.

Let’s summarize

This is a general overview of some of the key things to look for when choosing dewatering pumps for building a rental fleet of pumps. When it comes to specific applications, buyers should always discuss the application needs directly with their manufacturer. This conversation should include the following key considerations:

  • What is the maximum head height you need to pump?
  • How far do you need to pump the water?
  • What sizes hoses can you fit?
  • Do you have a specific flow you need to guarantee?
  • Do you have electrical power available? Electric or Diesel pump?
  • How accessible is the location where you will use the pump?
  • What is the size and depth of the pit?
  • What solids might you encounter?
  • How quickly do you need to start pumping? 
  • Are there noise or engine tier regulations to be considered?
