Pump Types; Pump Performance - Grundfos DMH 251 Installation And Operating Instructions Manual

6.3 Pump types

The DMH 25x dosing pump is available for a variety of
performance ranges in various sizes. Pump type and designation,
see pump nameplate.
The following is indicated on the pump nameplate (see section
6.1 Identification):
• The pump type which specifies the stroke volume, connection
size and performance data (see below).
• The pump serial number which is used to identify the pump.
• The most important characteristics of the pump configuration
e.g. for dosing head and valve materials. They are described
in section
6.2 Type key.
• Maximum flow rate and maximum counter-pressure.
• Mains frequency.
