the Jet pump von Einhell is one of the bestsellers and best-rated garden pumps on Amazon. Reviewers praise the excellent price-performance ratio. The pump should be very well made and do its job absolutely.

The garden pump from TROTEC has similar features as the model from T.I.P. - the delivery rate is identical, the other values are usually minimally lower. Only the engine power is 100 watts stronger. According to customer opinions, the water pressure is okay, and the volume also seems to be comparatively low. That clearly speaks in favor of buying this version.
Purchase criteria
Delivery rate
The delivery rate indicates in liters per hour (l / h) how high the maximum pumping capacity is - i.e. how much water the pump can deliver per hour. Most jet pumps have a flow rate between 2,500 and 6,000 liters. A high value is generally an advantage - and especially important if you need or want to transport very large amounts of water (for example when pumping water out of a pool).
Delivery head / delivery pressure
The delivery head is synonymous with the delivery pressure - only that the height is specified in meters and the pressure in bar. It is about the maximum distance that the water can travel from the jet pump to the exit from the hose. If the water has to overcome many meters on the way to the consumer (garden sprinkler), a high delivery pressure is elementary. Jet pumps can pump the water up to 60 meters high / far (delivery pressure of six bar).
Suction lift
Jet pumps often see themselves as self-priming pumps. The suction height refers to both self-priming and non-self-priming versions what depth or distance the pump takes the water over the coupled hose from the respective "Container" (Rain barrel, Cistern, Garden fountain et cetera) can suck in. Most pumps have a suction height of seven to nine meters. That should normally be sufficient.
Engine power
The fact is: the delivery head and volume depend not insignificantly on the engine power. In order to ensure a good delivery rate even with a higher delivery head, a high motor power is essential. Therefore, you should not disregard this criterion in your individual comparison. Most of the jet pumps have a nominal output between 400 and 1,300 watts.
Water temperature
Before buying or at the latest before using the pump for the first time, take a look at the maximum water temperature that the jet pump can handle. Often it is around 35 degrees Celsius.
material
Jet pumps are mainly made of plastic and metal, sometimes with parts made of steel. Read customer reviews and honest test reports to get an impression of the processing quality, robustness and stability before you buy. Incidentally, a sign of high quality is a rustproof stainless steel shaft.
Other characteristics
Self priming: If the jet pump is self-priming, it can bleed itself automatically. It does NOT mean that you do not need to fill the pump room with water beforehand.
Pressure switch: A jet pump with a pressure switch can be set individually and then operated automatically. It then switches itself on and off automatically.
Motor protection switch: A thermal motor protection switch protects the jet pump from overheating.
check valve: A check valve ensures that there is a constant water level in the hose - it prevents water from flowing back.
Protection against dry running: A dry run protection ensures that the jet pump cannot run dry.
Protection class: Since the jet pump is to be used outdoors, it must also have a corresponding protection class (IP X4 is OK).
volume: Ideally, the volume during operation is kept within limits so as not to annoy neighbors.

frequently asked Questions
What is a jet pump?
A jet pump is a garden pump that works hydraulically with turbines and is therefore also called a turbine pump. Another frequently used term is jet pump ('jet' means something like 'jet'). In principle, jet pumps are suitable for pumping water - for example from the Rain barrel to the Garden sprinkler.
How does a jet pump work?
An electric motor drives a small impeller. The latter is connected to the pump room via a nozzle system. A negative pressure is created in the narrowed suction line, which ensures that the pump sucks in the pumped medium through a lateral connection. A hose from the “water tank” (rain barrel et cetera) is connected to this nozzle. The water then exits the upper pressure port under pressure and flows through the hose connected there to the consumer (garden sprinkler et cetera).
What are the advantages and disadvantages of a jet pump?
A jet pump has few moving parts, so there is little wear and tear - and the device has a long service life. In addition, you hardly have to maintain a jet pump - it can often vent on its own. There are three disadvantages: The jet pump is relatively large and noisy. It is also important to fill the pump room with water before each use so that the pump can even initiate its work.
What is the difference between a jet pump and a centrifugal pump?
Jet and centrifugal pumps are constructed differently and also follow different physical laws. In contrast to the jet pump, which is based on the mode of action of the so-called impulse exchange, it works Centrifugal pump according to the principle of centrifugal force or - technically speaking - centrifugal force. Jet pumps are more often self-priming than centrifugal pumps.
Which brands offer good jet pumps?
Well-known and popular brands that manufacture high-quality jet pumps include T.I.P. and Einhell. As part of a domestic waterworks, the pumps are also available from numerous other well-known companies, for example Gardena, Hecht and Güde.

Occasionally you will also come across models for only 50 or more than 200 euros. When making a comparison, you should always pay attention to whether you are actually dealing with a “jet” version of the respective pump.
equipment
Suction hose
To use a jet pump, you will also need a suction hose. This should be as high quality as possible and have a diameter that matches the pump - it is often ½, ¾ or 1 inch. The inside diameter is decisive here. If necessary, there are also adapters that make the hose and pump compatible.

Pre-filter
A pre-filter is a practical accessory for the jet pump. It is inserted between the side port of the pump and the suction hose and thus functions as a link. The purpose of a pre-filter is to catch coarse dirt from the rainwater before it gets into the pump room and causes blockages there.
