Submersible Pumps and Macerators

It is possible to classify the pumps according to factors such as usage area, working principle, material, etc. Submersible pump models, as the name implies, are machines operated by immersion in water. During the application, the pump body is completely in the water and the pump motor is adjacent to the body. This makes sealing the most important criterion for submersible pumps.

Submersible pumps are devices that are used in many different industries and provide many advantages. Submersible pumps that work smoothly with many different fluids, especially water, mud, oil, etc., are the most suitable solution for different capacities, different depths and changing fluid flow needs. In this context, besides low capacity pumps with a head of 5 - 10 meters, there are also quite high capacity pumps such as 90 - 100 meters.

One of the areas where submersible pump usage is most common is mud discharge applications in tunneling, foundation digging, etc. In these applications, in order for the pump to operate more comfortably and efficiently, the sludge with large parts must be entered into the pump after it has been disintegrated. For this, on-line shredders are generally used. Thanks to these devices, small particle muds are constantly supplied to the pump.

General Features of Submersible Pumps

These pumps are generally robust and long-lasting, as they are designed to withstand very demanding operating conditions and are made of high-strength materials. The constant contact of the pump with water or other fluids makes it imperative that the material of the body and sealing equipment is selected specifically. For example, in submersible pump models that will operate in corrosive or chemically aggressive fluids, vinyl ester thermoset resins are used as body material. Wastewater treatment and seawater applications are the best examples.

Cavitation is one of the most common problems for each pump, regardless of type and model. However, since submersible pumps run completely in water and the pump is supplied with continuous liquid, it is unlikely that these pumps will experience cavitation problems. In addition, the pump is constantly in the liquid, the body's heating problems are eliminated.

The most important parameters to consider when choosing a submersible pump are:

Fluid flow (m³ / h)

Discharge height (m)

Maximum particle size (mm)

Type of fluid to be pumped (clean water, dirty water, chemical waste water, sludge, etc.)

Electricity consumption (kW)

Other devices and equipment (such as shredder) that should be used with the pump

Where is Submersible Pump Used?

Submersible pumps have a wide range of applications, thanks to their easy installation and commissioning, ability to pump high-viscosity and coarse-grained liquids, and low noise and vibration levels. The main areas and applications where these pumps are used most frequently are:

Access to clean water resources

Water treatment plants

Tunnel and well drilling applications

Basic drain for digging applications in the building industry

Petroleum extraction processes

Mud and dirty water drainage
