Submersible Pumps: Construction Features for Domestic Applications

Water supply is a critical undertaking in commercial and domestic setups. When cleaning or watering your beloved plants in the garden, a consistent and reliable water supply makes everything easy and enjoyable in the home. The only way to optimise your water supply is by investing heavily in the pumping system. The maze of conduit pipes, valves and access points must sit right for you to make the most of the system. More importantly, a good-quality water pump takes centre stage in the whole operation. Choosing the right one requires balancing the pump's construction features with your usage needs. Here are the go-to features for a submersible pump designed for domestic purposes:

The Motor

The motor plays a crucial role in the working mechanism of a submersible pump. It generates power to rotate a shaft that consequently moves the impellers. This enables the impellers to lift water through the conduit pipes towards the designated storage or access points. Typically, a submersible, continuous-duty motor should suffice for pumping clean water. The motor should also be asynchronous, meaning that it relies on electromagnetic current from a special magnetic field to generate the torque needed to move the impellers.

It also helps to go for an airtight stainless steel casing around the motor. Such a casing keeps air from reaching the motor's delicate components, reducing the risk of corrosion since the motor is always in contact with water.

The Cabling

It is paramount to pay attention to the cabling because it carries the current needed to power the motor. The choice here includes a single-phase or three-phase option. Single-phase cabling suffices for regular domestic needs, such as pumping water to a storage tank before supplying to the house. The cabling comes with a neutral and phase wire. The neutral wire provides a return path while the phase cable transfers the current to the motor.

You can go for a three-phase option if the pump supplies water to multiple access points in the home. Several storage tanks and a connection to the farm for irrigation are examples of a setup that needs a three-phase. Usually, the benefit of a three-phase connection is the ability to support auxiliary features such as automated float switches.

The Pump

The pump houses all the components that support the motor. Ensure the housing features a hydraulic section fitted below the motor to provide room for cooling by the pumped water. The pump should also have diffusers, strainers and impellers made using tough thermoplastic, abrasion-proof material.

Keep these features in mind as you look for submersible pumps.
