3.5 Main characteristics
The pump size is designated by the displacement volume of 100 revolutions expressed
in litres (or dm
3
) but rounded followed by the nominal port diameter expressed in
millimetres.

Maximum viscosity
*) Remark:
Figures are for Newtonian liquids at operating temperature. The maximum allowable viscosity
between the sliding faces of the mechanical seal depends on nature of liquid (Newtonian, plastic
etc.), the sliding speed of the seal faces and the mechanical seal construction.
