Silent gear pumps serie Elika

New external gear pump series from Marzocchi with patented conjugated helical tooth profile. The result is an outlet flow with very low pressure pulsations minimizing vibrations transmitted through air & pipework.Low number of teeth (seven) results in lower frequency pulsations that is less intriguing to the ear.

Directly interchangeable with Marzocchi GHP2, GHP3 and ALP2, ALP3 pumps + other makes
Hydrostatically balanced design for no axial loads.
Unidirectional rotation
Very high volumetric efficiency, little increase in volumetric loss over time.
Inherent very good low speed characteristics.
Pressure capability up to 300bar
Wide range of shaft and flange options available.

Internal gear pumps for low viscous liquids - series QXV

Specially designed for low viscosities and aggressive liquids. The unique design allows the liquid down to 1 cSt to be pumped because the pressure is built up incrementally as needed and therefore compensates leakage due to viscosity. The uniqueness of Truninger special pumps, are an extremely low noise level compared to other types of pumps for liquids of low viscosity. .

Pumps liquid down to 1 cSt.
Press building approx. 25 to 50 per element at 1-2 cSt.
Max ca. 250 bar at approx. 1.5 to 2.0 cSt.
Volumetric efficiency of approx. 65-70%
Can pump diesel, gasoline, jet fuel, naphtha, "sub sea oil" etc.
