Diaphragm pumps
■ The VACUUBRAND diaphragm pump line includes pumps with a wide range of flow rate and ultimate vacuum. Singlestage
diaphragm pumps reach as much as 70 mbar (absolute) vacuum. By connecting pump heads in series of two,
three or four stages, we can create pumps with ultimate vacuum reaching 0.3 mbar on some models. Connecting the
heads in parallel produces higher flow rates. VACUUBRAND pumps combine these options to create pumps with the
capabilities you need for most applications.
Nomenclature for VACUUBRAND pumps is built from the following codes designating specific features or
components:

The pumping speed of all pumps is measured according to ISO 21360
M = diaphragm (membrane) pump
E, Z, D, V = number of pump stages from single ("E") to four ("V") stage design
NT = labels the new series of pumps comprising the New Technology
® VARIO or VARIO-B = speed controlled pump with vacuum controller CVC 3000
■ unique VARIO ® regulation offers the distinctive control advantages and convenience of the CVC 3000 controller

■ unsurpassed diaphragm and valve lifetime by reducing the total number of diaphragm strokes
■ exceptionally quiet, with very low vibration and measurably lower energy consumption

® pumps include patented TURBO·MODE TM with automatic speed adjustment that provides even better
backing when used as a fore-pump for turbomolecular drag pumps (capable of working with backing pressure
in the mbar range). The result is a cooler running turbo pump with better residual gas properties
