Made of stainless steel, the housing of the garden pump is rust-free
In online tests for water pumps, it is reported that housings for garden pumps are primarily made of the following materials:
Because rainwater can be slightly acidic, it is possible that housing made of cast iron or steel is susceptible to corrosion. best all in one pond pump and filter made of stainless steel and plastic, the housings are rust-free. Although plastic housings are lighter than the metal variants, the shape of the housings can be built with plastic in such a way that the garden pump is quieter or at least quieter than models made of metal types.
Good to know: The volume of a garden pump can be up to 90 decibels with a suction pump, as loud as an electric wood saw or loud doorknobs. Submersible pumps are quieter because they are sunk into the water.
From the outside, the housing of the suction pump should be at least splash-proof so that no rainwater can penetrate into the pump and the engine and electronics do not get wet. Submersible pumps must be completely waterproof.
Online tests indicate the weight of a garden pump as a quality criterion
This means that the heavier a garden pump is, the higher the quality it is. However, the size of the garden pump also plays a role in addition to the material used for the weight. Small garden pumps weigh only two to three kilograms. These are essentially narrow submersible pumps. Suction pumps usually weigh 10 and 25 kg.
Tip: If you want to use the garden pump mobile and use it in different places, then an ergonomic carrying handle is recommended for easy transport.
A garden pump with a pressure switch is particularly advisable for continuous operation
If a garden pump is used as a home automation machine, then a uniform water pressure is necessary. A pressure switch is also practical for the continuous operation of the garden pump. A pressure switch ensures that the pressure of the water output always remains the same. If the pressure drops, the pressure switch ensures that the garden pump is started automatically and the pressure is increased. A pressure switch can also be retrofitted as an accessory.
A filter ensures that dirt particles do not enter the conveying water
A garden pump is only suitable for clean clear water. Nevertheless, it can happen that there are dirt particles in the water. So that these do not get into the water and into your garden, a so-called pre-filter keeps them back.
A garden pump with an automatic switch-off ensures your safety
A garden pump is ideally equipped with various safety functions, such as the automatic switch-off with dry-running protection and overload protection as well as a check valve.
The automatic switch-off of the garden pump refers to the dry running protection and the overload protection. The dry-running protection prevents the calculate pond pump size from continuing to run without water, for example, if the pool is already empty during drainage. The overload protection prevents the garden pump from overheating and also ensures that the garden pump is switched off.
A check valve also prevents the overloading of the pump. It can be integrated into the pump or in the hose. It allows water in the pump to flow only in one direction and therefore prevents the return flow of the water, the so-called setback.
