Before buying a new pump, make sure that you have plenty of questions to ask the manufacturers.


A pump can only pump certain types of fluids. These include clear water, grey water, sewage, and saltwater. The latter are usually used to pump these media

Volume of pump:

 The amount of water that needs to be pumped dictates the output of the pump. Most pumps produce varying levels of output, ranging from 0 to 30 m3/min.

Extreme medium:

 This question is related to the previous one because the higher the pump’s volume, the less it will pump. Generally, high pressure pumps can pump up to 200 meters if the horizontal distance is big enough.

Volume of water;

If a pump is frequently used, it is recommended that it has a permanently attached level sensor. This type of pump is more reliable and can be operated automatically

Does solid matter in the pumping medium?

This question is especially important when it comes to grey water and sewage pumps, which can only handle a limited amount of solid matter. Usually, if the filter size is larger than 30 mm, the particles can still pass through.

Power source:

The connection distance between the pump and the site is often not taken into account when choosing a capacity range. Also, if the power supply is used, it is usually not considered when determining the start-up current.Most pumps are operated in a single phase with 230 V or in three phases with 400V


  Some pumps can only be installed in dry areas while others are designed to operate underwater. If these conditions are not ideal, then they should be mounted on a permanent basis.

Instead of having to return the pumps to the manufacturer for servicing, opting for modular pumps can save you money and avoid downtimes.


Having the right information about the pump will help you make an informed purchase. Another important factor that users should consider is the delivery time. Usually, most pumps are produced to order
