ULVAC Mini Vacuum Pumps – Oil-Free Compact Solutions for Laboratory Applications
ULVAC mini vacuum pumps are compact, oil-free diaphragm vacuum pumps specifically designed for laboratory, medical, and portable applications. These lightweight pumps combine quiet operation, maintenance-free performance, and reliable vacuum generation in an extremely compact package. Perfect for applications where space is limited and clean, oil-free vacuum is essential.
🎯 What are ULVAC Mini Vacuum Pumps?
ULVAC mini vacuum pumps are small diaphragm vacuum pumps based on the principle of oscillating diaphragm displacement. They are specifically designed for applications requiring:
- ✓ Compact size – fits in tight spaces
- ✓ Quiet operation – suitable for laboratory environment
- ✓ Oil-free vacuum – no contamination
- ✓ Low maintenance – minimal service requirements
- ✓ Portability – lightweight and easy to move
- ✓ Chemical resistance – handles various gases
⚙️ Operating Principle:
Diaphragm Vacuum Pump Technology:
- Electric motor drives an eccentric cam
- Eccentric cam causes diaphragm to oscillate
- Diaphragm movement creates alternating expansion and compression
- Inlet valve opens during expansion – gas is drawn in
- Outlet valve opens during compression – gas is expelled
- Continuous cycles create steady vacuum
