Medical vacuum pump KV 40

laboratorydentalpiston

Overview
Oil-free piston vacuum pumps from Dürr Technik deliver steady suction performance with minimal maintenance. Designed for laboratory, production, medical-technology and industrial installations, these compact flange-mounted pumps cover a pumping range of approximately 25–150 l/min and are available in single- and two-stage designs (two-stage models achieve ultimate vacuum up to 30 mbar). Precision bearings and direct flange mounting on the motor make them suitable for built-in installations and long operating intervals without oil changes.

Key benefits

• Low noise levels
• Long service life
• Maintenance-free operation (no oil changes required)
• Compact, flange-mounted design for machine integration
• Consistent flow over long operating hours

Examples of applications

• Handling (vacuum lifters, pneumatic controls)
• Measurement technology (leak tests, density testers)
• Medical sector (secretion aspirators, disinfection units, cryolipolysis, orthopaedic technology)
• Jewellery industry (kilns, wax casting)
• Dental industry (ceramic kilns)
• Rail transport (vacuum toilets)
• Packaging (suction of cardboard packaging)
• Environmental technology
• Laboratory use (gas analysis)

Series & main characteristics (summary)

• KV8 Series: Portable; installable vertically or horizontally; virtually maintenance-free; compact flange mounting; low noise and long service life; constant flow suitable for built-in applications.
• KV15 Series: Two-stage variants for enhanced suction and operational reliability (suitable for continuous 24 h operation); oversized bearings for extended life; stable pumping speed over many operating hours.
• KV40 Series: Engineered for continuous-duty operation with nearly constant flow after thousands of hours; high ultimate vacuum for two-stage variants (up to ~30 mbar); 100% duty cycle and reinforced bearing design for long service life.
