6.6. Pump

Water pumps are used to provide water circulation in the geothermal system. These water

pumps, which use electrical energy, can be of different sizes and modes of operation,
depending on the size of the system. Amateur geothermal systems can use a powerful

aquarium pump or a medium-sized submersible pump, while larger commercial geothermal
systems should use steel or HDPE-bodied electric water motors.

Electric water motors have started to be produced with HDPE body with today's technology,

corrosion is prevented with this material and the service life of the motor is increased. In

addition, electricity consumption is minimized with hybrid technology in similar engines.
Adjusting the flow rate of the water engine to be used will allow you to circulate the desired

amount of water in the system.

Picture 27. Types of pumps that can be used in the geothermal system (left to right:

submersible pump, steel-bodied electric water pump, HDPE-bodied flow-adjusted hybrid
water pump)

In the geothermal system installation, the amount of pump/motor to be used in the system

should be minimized by making the correct calculations and using the water level difference

correctly. This will reduce electricity consumption. However, in case of any malfunction or
maintenance, the presence of a spare water pump in the system will help you to guarantee the

system in order to ensure the continuity of the water in the system.
