electric pumps

Q: How to choose an electric water pump?

The choice depends on the required flow rate, the pumping head, the type of water, the pumping distance, and the application. Motor power alone does not determine whether a pump is suitable.

Q: What is the difference between a submersible pump and a surface pump?

A submersible pump operates underwater, while a surface pump is installed outside the liquid and draws water through a pipe. Each system has different applications and limitations.

Q: What is a multicellular pump?

It is a pump that incorporates several impellers or hydraulic stages to achieve greater pressure or pumping head. It is commonly used in water supply, pressure boosting systems, irrigation, and other installations where increased pressure is required.

Q: What are the advantages of a variable speed pump?

It allows adapting the motor speed to the installation's demand, which can reduce electricity consumption, improve pressure control, and decrease equipment wear.

Q: How can you tell if an electric pump has enough pressure?

It is necessary to check its operating curve and compare the available manometric head with the head and pressure losses of the installation. The maximum pressure or flow rate data should not be considered alone.

Electric water pumps are essential equipment in installations where it is necessary to move, lift, recirculate, or evacuate water in a controlled manner. Their selection depends primarily on the type of application, the required flow rate, the head, the type of water, and the operating conditions.

At Hidromar we have different families of electric pumps to cover very different applications:

Bilge pumps, to evacuate water from wells, basements, tanks, garages or flood-prone areas.
Filtration pumpsintended for water recirculation in swimming pools and other systems.
fountain pumpsdesigned for ornamental installations, waterfalls and fountains.
variable speed pumps, which allow the engine's operation to be adapted to the actual needs of the installation.
Multicellular pumps, indicated when higher pressure or pumping height is required.
submersible pumps, prepared to work totally or partially in the water.
Submersible motors, used in certain pumping equipment and systems.
Specific pumps for cooling and recirculation.

To select the right electric pump, it's not enough to focus solely on the motor's power. You also need to check the hydraulic curve , the operating flow rate, the total discharge head, the pipe diameter, and the water's characteristics.

If you have doubts about which pump you need, it is especially useful to know the desired flow rate, lift height, pumping distance, pipe diameter and water type.
