Engineered for factory automation applications, Rotary Vacuum Pumps feature fully balanced design that minimizes vibration. Minimum clearance between rotor and cylinder wall of pump results in virtually contactless design and reduction in sliding parts. Because pumps use magnet coupling, and no sliding seal is required, maintenance due to seal abrasion is not necessary. Pumps generate low heat through use of forced air cooling system and operate at virtually silent noise levels (≤58 dB [50 Hz).
