the Centrifugal pump from Agora-Tec is described by the reviewers on Amazon as a very powerful pump for garden irrigation. It should have excellent pumping performance and be relatively quiet in operation, which is anything but natural with this type of pump. In addition, buyers of the model praise its high-quality materials and workmanship. This centrifugal pump also seems to prove its worth in the long term, even if it is not self-priming.

In contrast to the centrifugal pump from Agora-Tec, the IBO / DABAT variant is entirely self-priming and can therefore vent itself. The conveying performance is also convincing, as the reviewers at Amazon confirm. The multistage centrifugal pump is apparently suitable for both a
Domestic waterworks as well as for use in the garden. The unanimous opinion is “a good pump at a good price”.Multi-stage centrifugal pump 6000l / h 550W delivery head 35m, 2900rpm, for domestic waterworks

The centrifugal pump from the renowned Wiltec brand is our price-performance winner. It is true that it performs worse than the other two pumps in our comparison in some performance data - especially in terms of engine power and delivery head or delivery pressure; however, it also costs less. The previous reviews (as of November 2020) have been excellent - all customers have given this centrifugal pump the full number of stars.
Purchase criteria
Art
Domestic waterworks: A domestic waterworks with a centrifugal pump is specially designed to supply the house with drinking or service water. Here the pump does not direct the water directly to the target lines. Instead, it first goes into a pressure vessel. From there it is constantly available to the consumer (tap, toilet flush, etc.) in the required amount.

Garden pump: A centrifugal pump as a simple garden pump is usually built compactly and does not require a pressure vessel. It sucks in the water through a suction hose and generates a continuous flow of water through the rotating impeller.
Type
Radial pump: With the radial pump, the water exits the impeller perpendicular to the pump shaft (radial). This can generate stronger centrifugal forces and thus result in an increase in pressure.
Diagonal pump (semi-axial pump): With the diagonal pump, the water exits the impeller at an angle to the pump shaft (semiaxially).
Side channel pump: The side channel pump is characterized by its automatic suction capacity. It can convey gas undamaged. The following applies: the lower the speed, the better the suction capacity and the lower the risk of cavitation.
Peripheral pump: With the peripheral pump, the water flow is generated in a peripheral ring channel. It is ideal for small delivery rates and a high delivery pressure.
Axial pump (propeller pump): In the case of an axial pump, often also called a propeller pump, the water exits the impeller parallel to the pump shaft (axially).
Delivery rate
Delivery rate: How many liters of water can the centrifugal pump convey per hour? Usually it is between 2,500 and 13,000 l / h. At least 5,000 to 8,000 l / h is recommended in houses, and 3,000 l / h is often sufficient for garden irrigation.
Delivery head: How many meters high or how far can the centrifugal pump deliver the water? The maximum is usually 60 meters (on the best models).
Delivery pressure: With what delivery pressure can the centrifugal pump convey the water? This value is given in bar and usually reaches a maximum of six bar. Strictly speaking, head and pressure are synonymous, they define the same "output" with different units.
Suction lift: From what distance can the centrifugal pump draw in the water? Generally this value is between six and twelve meters.
Speed of the impeller: At what speed does the pump wheel turn? The spectrum is very broad with 1,000 to 30,000 revolutions per minute (rpm).
Engine power: Also take a look at the engine power. The higher it is, the more pressure the centrifugal pump can build up and thus transport larger amounts of water. Most models are rated at between 300 and 1,500 watts.
Splash protection
Make sure that your chosen centrifugal pump meets at least protection class IP X4 in order to be splash-proof.
check valve
Ideally, the centrifugal pump is equipped with a check valve. This prevents water from flowing back.
Clear water or dirty water
When buying your centrifugal pump, make sure that it is only suitable for clear water or also for dirty water (waste water). Most versions only work with clear water. If there are coarser dirt particles (larger than two millimeters) in the water, these devices can clog and give up the ghost. In contrast, a dirty water pump can handle particles up to a certain size without any problems. It is mainly used for draining a full cellar or pond.
frequently asked Questions
What is a centrifugal pump?
A centrifugal pump is a pump for the domestic waterworks or a specific garden pump that is used to Irrigate garden. You can get water from one Rain barrel or another source with more or less high pressure to a specific consumer, such as a sprinkler system.
How does a centrifugal pump work?
The way a centrifugal pump works is based on what is known as centrifugal force: there is a rotating impeller in the pump housing, driven by a motor. Now the rotary movements of the impeller activate the mentioned centrifugal force: a suction is created - that Water is drawn from the source into the pump housing and then to the discharge hose or pipe pressed.
What does "self-priming" mean in a centrifugal pump?
Centrifugal pumps are often referred to as self-priming. The term is very misleading, however, as it suggests that the pump could suck the water completely from the original source without the gardener having to do anything. But: The gardener must first fill the housing and the supply line with water so that the pump works. “Self-priming” mainly means that the pump can vent its suction line without an external auxiliary device.
What is a centrifugal pump suitable for?
Centrifugal pumps are basically used wherever process water comes from a rain barrel or a Wells can be used - for example to water the garden or for the Toilet flush. The centrifugal pump then serves to transport the water from the respective source quickly and literally with pressure to the destination. Centrifugal pumps can also be used to drain the pool.
Which brands offer good centrifugal pumps?
Well-known and popular brands for centrifugal pumps are, for example, Einhell, T.I.P., Wiltec and Agora-Tec. You can find pumps from these manufacturers at Amazon, among others. In principle, you can also buy centrifugal pumps in well-stocked specialist garden centers and hardware stores. However, the ordering process at Amazon is usually much more convenient.
How much does a centrifugal pump cost?
Classic centrifugal pumps for the garden usually cost between 70 and 200 euros. Occasionally you come across cheaper or more expensive models. There are gasoline-powered centrifugal pumps that cost up to 400 euros. However, these versions are used almost exclusively in the professional (commercial) area.
