Laboratory vacuum pump MV 10C EX VARIO

diaphragmmulti-stageoil-free

Overview

• ATEX-compliant chemistry diaphragm pump with VARIO® speed control for adaptive vacuum regulation
• VARIO®: hysteresis-free vacuum control for reduced process times
• On-demand operation: minimized power consumption, extended maintenance intervals and low noise
• Optional VACUU·SELECT or CVC 3000 vacuum controllers with ATEX vacuum sensor and Connection Box 100 enable fully automatic processes
• Additional ATEX components (vacuum sensor, Connection Box, controller) required for safe automated operation

Product highlights

• Model: MV 10C EX VARIO (four stage)
• ATEX conformity for pumped gases and motor (see technical data)
• Oil-free, chemically resistant diaphragm technology
• Speed control via 4–20 mA current loop (4 mA = 0 rpm, 20 mA = 1500 rpm)
• Delivered completely mounted with two motors, control and mains cables (10 m, without plugs)

Key performance values

• Ultimate vacuum (without gas ballast): 2 mbar (≈ 1.5 torr)
• Ultimate vacuum with gas ballast: 10 mbar (≈ 7.5 torr)
• Max. pumping speed (50 Hz): 8.1 m3/h
