Pump safety and protection recommendations:

Note All electrical appliances need protection system. Failing to use protection system, not only can seriously harm the equipment, but can also invalidate every right to assistance under warranty. Protection Percentage of Protective systems Built-in thermal protector is installed directly on single-phase pumps winding by the manufacturer and has only 50% protection depending on the power of the motor. For example an electric motor with a power of 0.37kw is protected up to 60% by using built-in thermal control protector.

Look at the following table:

Note

Some of the three-phase electric-pumps are equipped with thermal protection systems (Thermo guards) placed inside an external control panel on the circuit line. This protection system for all pumps with different powers can provide up to 75% complete protection.

Thermal starter

If the starting-up method is proportional to the power of the motor as well as the consumed current rate and regarding to the setting of the current rate of starter protector (Amax × 1.1 = As), all single / three phase pumps are protected up to 50% and 30% respectively.

Note

It is the least protective device for a pump that can also be used as a power switch. All miniature switches operate like these starters

The disadvantages of these starters are to fail to being protected against open phase, delay operation and unable to be connected to other external controllers.

Electronic starters

These starters operate based on the consumed current and depending on the setting of protective parameter cut off power immediately when the current is increased. It can provide up to 90% protection in single-phase motors, 80% in three-phase motors (if open phase control is used) and 50% ( if open phase control is not used ).These starters are unable to be connected to other external controllers.

Electric control panel

These control panels consist of power contactors, bimetal (thermal) protectors, phase controllers and start / stop current transducers. These panels can provide up to 50% complete protection due to the high quality of the electrical components and their ability of phase control.

Digital Control Panel

Due to their quality and high accuracy in measuring electronics and the possibility of installing multiple external controllers, they can provide 80 to 100% protection. The benefits of these panels include initial accurate settings, easy to use, phase controlling, phase sequence controlling, electrical shock protection and the possibility of being connected to other external controllers such as mechanical floater, thermal systems, humid meter and more. These digital panels are manufactured in different models and types to meet consumer’s needs. Gol pumps technology has provided a number of them that fully meet consumer needs.

Soft starter control panels

These control panels are used for contactors and electrical appliances and feature a soft starter protection system. This protection system is almost as efficient as digital panels and is used to start up electromotor above 10HP. These types of controls can protect up to 80%.

Inverter control panels

These panels feature electrical accessories such as contactors, starter/stops switch and a inverter that can manually or automatically control the rotation speed of the pump. This control panel is often used in booster pump systems where the flow rate varies but it is necessary to keep the pressure of a hydraulic circuit constant by varying the rotation speed of the electro pump.
