The difference between three phase and single phase is primarily in the voltage that is received through each type of wire. There is no such thing as two-phase power, which is a surprise to some people. Single-phase power is commonly called “split-phase.” You have some ways to determine whether you have three-phase wire or single-phase wire.

Single Phase Motor

A single-phase wire consists of two hot wires, each delivering 120 volts, and one neutral wire. Appliances requiring 240 volts, like water heaters and stoves, utilize both hot wires. Other appliances operate on 120 volts, using only one hot wire and the neutral. This split-phase circuit design facilitates diverse voltage requirements efficiently.

Three Phase Motor

Three-phase power is supplied by four wires. Three hot wires carrying 120 volts of electricity and one neutral. Two hot wires and the neutral run to a piece of machinery requiring 240 volts of power. Three-phase power is more efficient than single-phase power. Imagine one man pushing a car up a hill; this is an example of single-phase power. Three-phase power is like having three men of equal strength pushing that same car up the same hill. The three hot wires in a three-phase circuit are coloured black, blue and red; a white wire is neutral and a green wire is used for the ground.

Yes. If the pump is labelled “submersible” then the whole pump and cord can be put under water. The only thing that must not be submerged is the plug and the power source.

It is best to use a hose or pipe that is the same size as (or larger than) the pump’s actual discharge. Using a reducer, smaller hose, or smaller pipe, will reduce the output of the pump. If reduced too much, the pump can even be damaged.

Static head measures the total vertical distance that a pump raises water. It has two components: static lift and static discharge. Static lift measures the elevation difference between the water source and the pump, while static discharge measures the elevation difference between the discharge point and the pump.

HZ is short for Hertz, which is the unit of an international standard unit of frequency of an alternating current voltage. 50HZ means the voltage alternates 50 times per second and the 60HZ means it alternates 60 times a second.

In short, the answer depends on the power supply where the pump is being used, UK and Europe generally have a 50HZ power supply, but Americas and other parts of the world use 60HZ. It is important to match the pump to the power supply to the pump operates at it.

It is best to use a hose or pipe that is the same size as (or larger than) the pump’s actual discharge. Using a reducer, smaller hose, or smaller pipe, will reduce the output of the pump. If reduced too much, the pump can even be damaged. There are many different types of hose that we supply depending on your application.

The Ph range matters because certain liquids are corrosive and the pump will not last as long in some environments. For example, the Ph value of salt water is different from that of clean water. This will be detrimental to the life of the pump. To get around this you could use a different type of pump – for example, a stainless steel one, or change the materials of the pump such as the seals. You can also use zinc anodes which will prolong the life of the pump.
