Diaphragm pumps are an independent type of displacement pump, which are used in several fields, e.g. in family houses with small gardens. An elastic diaphragm is moved up and down by a piston. During the downward stroke the liquid is sucked through the inlet valve. During the upward stroke, the diaphragm presses the fluid out through the outlet valve from the pump head. The pumping cylinder is hermetically separated from the pump drive by the diaphragm. This means that diaphragm pump supplies uncontaminated fluid. Thus, all essential water fixtures can be sufficiently supplied in a single-family house by using very small pumps with very small flow rates. Due to the huge benefits in energy consumption and performance, suction characteristics and especially low noise level, these pumps are increasingly used in the single-family house applications, e.g. in the domestic water unit, RAINMASTER Eco. The optimum range of all fixtures in a single-family house falls very close to the pump characteristic curve. In contrast, for centrifugal pumps, which are currently used for rainwater harvesting, the usual operating points are very far from the characteristic curve (see diagram). This implies unnecessary power consumption in virtually all operating conditions of the centrifugal pump. The diaphragm pump, selected for rainwater harvesting or greywater recycling, ensures a maximum pressure of 3.5 bar and a maximum flow rate of 10 L / min. This is not only sufficient for most applications in a single-family house, but also offers an ideal performance range. For the most commonly used fixtures, e.g. toilet flushing, even 1 bar and 5 L / min is actually sufficient (see diagram). If several fixtures are simultaneously opened, then this results simply in a longer filling time for the fixture.

==Membranpumpen für das Einfamilienhaus==
[[File:193px-DiaphragmPump.gif|frame|link=https://commons.wikimedia.org/wiki/File:DiaphragmPump.gif#/media/File:DiaphragmPump.gif|Funktion Membranpumpe]]
Membranpumpen sind eine eigenständige Pumpenbauart von Verdrängerpumpen, die in vielen Bereichen eingesetzt werden wie z.B. in Einfamilienhäusern mit kleineren Gärten. Eine elastische Membrane wird durch einen Exzenter auf und ab bewegt. Im Abwärtshub saugt sie die Flüssigkeit über das Einlassventil an. Im Aufwärtshub drückt die Membrane das Medium über das Auslassventil aus dem Pumpenkopf hinaus. Der Förderraum ist vom Pumpenantrieb durch die Membrane hermetisch getrennt. Deshalb fördern die Membranpumpen die Medien völlig unverfälscht. So können mit sehr kleinen Pumpen mit einem sehr kleinen Volumenstrom alle wichtigen Verbraucher im Einfamilienhaus ausreichend versorgt werden. Aufgrund der großen Vorteile seitens Energieverbrauch und Leistung, Ansaugeigenschaft und besonders geringer Lautstärke, finden diese Pumpen eine immer größere Verbreitung im Segment Einfamilienhaus, z.B. im Hauswasserwerk  [http://www.intewa.de/products/rainmaster/rainmaster-eco/ RAINMASTER Eco]. 
Der optimale Bereich aller Verbraucher beim Einfamilienhaus liegt in der Nähe der Pumpenkennlinie. Bei Kreiselpumpen, die gegenwärtig in der Regenwassernutzung eingesetzt werden, sind die üblichen Betriebspunkte sehr weit von der Kennlinie entfernt (siehe Diagramm). Das bedeutet überflüssigen Stromverbrauch in fast allen Betriebszuständen der Kreiselpumpe.
Die für die Regenwasser- oder Grauwassernutzung ausgewählte Membranpumpe gewährleistet einen maximalen Druck von 3,5 bar und einen maximalen Volumenstrom von 10 l/min. Das ist für die meisten Anwendungen im Einfamilienhaus nicht nur ausreichend, sondern ein idealer Leistungsbereich. Für den am häufigsten benutzten Verbraucher, die WC-Spülung, reichen sogar 1 bar und 5 l/min (s. Diagramm). Sollten mehrere Verbraucher gleichzeitig geöffnet werden, führt dies nur zu einer längeren Befüllzeit der Verbraucher.
