Chemical-resistant diaphragm pump engineered for continuous, oil-free pumping of corrosive gases and vapors. The two-stage design delivers the optimal combination of high pumping speed and low ultimate vacuum. All components contacting the pumped media are constructed from chemically resistant fluoroplastics. Proven PTFE sandwich diaphragms enhance reliability and extend service life. The MZ 2C NT model features a gas ballast valve for optimized condensate discharge capacity with improved condensable vapor pumping. This pump represents the most popular model in our chemical diaphragm pump portfolio and serves as the core component in VACUUBRAND pumping system families. The NT series delivers advanced performance specifications and superior vapor tolerance characteristics.

Frequently Asked Questions

What makes this diaphragm pump suitable for chemical applications?
All wetted components are constructed from chemically resistant fluoroplastics, and the proven PTFE sandwich diaphragm design ensures compatibility with corrosive gases and vapors while maintaining long operational life.
What is the function of the gas ballast valve?
The gas ballast valve optimizes vacuum performance when pumping condensable vapors and facilitates continuous condensate discharge, preventing liquid accumulation in the pump.
What is the ultimate vacuum without gas ballast activation?
The pump achieves an ultimate vacuum of 7 mbar (absolute) or 5 Torr without gas ballast engaged.
Is this pump oil-free?
Yes, this is an oil-free diaphragm pump design suitable for clean, contamination-free vacuum applications.
What certifications does this model hold?
The MZ 2C NT carries NRTL certification for Canada and USA markets, and ATEX compliance (II 3 / − G IIC T3) for the 230V version in appropriate atmospheres.
