General overview of water pumps

Large gardens need plenty of water, especially in summer. Using natural sources instead of tap water is not only better for the environment, but it is also cheaper. A water pump helps out here and makes it easier to deliver water from cisterns, wells and shafts. With a garden pump you can quickly and easily use the water collected in the reservoir for watering the garden. Our dirty water multi-purpose pumps are also suitable for pumping off ponds and building pits as well. Our domestic waterworks take this a step further, allowing the natural water reserves to be used effectively in the home as well, for example for toilet flush systems.

Operation purposes of water pumps

Watering

Einhell Garden Pump GE-GP 9041 E

The high quality and high performance garden pumps from Einhell offer excellent support to ambitious hobby gardeners when it comes to pumping groundwater or making use of rainwater to water the garden. This not only helps the environment, but it also goes easy on your wallet as well. In addition, we also offer a deep well pump, which has been specially designed to pump clear water from reservoirs, wells and shafts.

Dewatering

Einhell Dirt Water Pump GE-DP 7330 LL ECO

Our pump models can be used straight away for fast and powerful pumping of water out of pools or ponds, or as an emergency measure to deal with a flooded cellar. Dirty water pumps are suitable in particular for the drainage of contaminated water. By contrast, clear water and submersible pressure pumps are used for pumping out clear water. Our combination pumps in particular are genuine multi-talents, as they can suck out both clear water and dirty water.

Domestic water supply

Einhell Water Works GE-WW 9041

If you want to use collected rainwater or groundwater automatically and under constant pressure in the house, for example for a washing machine or toilet flush system, then our domestic waterworks and automatic waterworks are the perfect solution. In addition to providing domestic water supplies, the automatic waterworks can also be used to water the garden. The intelligent pumps react automatically as soon as a connected tap is opened or a domestic appliance is switched on. A great advantage of these pumps is that they are environmentally friendly and extremely frugal in their use of water.

Glossary for water pumps

Here you find all important water pump terms briefly explained.

Delivery height

The delivery height describes the difference in height between the pump and the outlet of the water from the connected hose/sprinkler (caution: in the case of pumps that are submerged in water, the position of the pump is not used, but instead the height of the water surface).

Delivery capacity

The delivery rate, also referred to as the pumping capacity or suction capacity, describes the pumping capacity of a pump and is normally stated in 'liters per hour'. The delivery rate can also be described as a volumetric flow or flow rate, where the units 'cubic meters per second' are used. The delivery rate corresponds with the delivery head. The higher the water has to be pumped, the smaller the delivery rate is.

Delivery pressure

The delivery pressure describes the pressure with which the pump acts on the fluid being pumped. The higher the force of the pump used for pumping, the higher the pressure. Pressure is generally measured in bar, occasionally also in pascal. Additionally, the delivery pressure informs about the delivery head. For example 35 metres delivery head correspond to 3,5 bar delivery pressure.

Suction height

The suction height defines the height difference that can be overcome between the component at the heart of the pump, the paddle wheel, and the surface of the water. The suction capacity is based on the atmospheric air pressure under real conditions, as a result of which pumps generally face a theoretical limit of around 8 meters.

Service water

Service water is water that is pumped by means of a pump from a well, shaft or cistern. Service water is not potable and must not be used for drinking water or for the preparation of food. In private households, service water can be used in separate outlets away from the drinking water supply as a supply for toilet flushing systems or washing machines, or as cleaning water.

Dirty water

Dirty water is the combined total of all waste water in the household and in commercial or agricultural operations, and it is heavily contaminated with bacteria. Dirty water must be purified via mechanical, chemical or biological means before it can be fed back into the water circuit.

Clear water

Clear water is slightly contaminated waste water with no particulate content. This includes waste water from personal hygiene, but not kitchen waste water, which is excluded because of the high levels of oils and bacteria from food waste. Clear water is not potable and must not be used for drinking water or for the preparation of food.

Pre-filters

Pre-filters prevent the ingress of contamination into the pump. Their use is always recommended if the pump is expected to pump water that may be contaminated and may contain sand or dirt particles.
