Hot Sale China Factory High Quality Screw Vacuum Pump Permanent Magnet Frequency Conversion Progressive Pump

Q1: How much energy can I actually save?
A: The permanent magnet motor is 20-30% more efficient than ordinary motors. Combined with intelligent frequency control, the total electricity savings reach 50-60% compared to traditional vacuum pumps.

Q2: What is the maximum vacuum degree?
A: Our unit achieves -0.098MPa, significantly higher than the market standard of -0.07MPa. Ultimate vacuum can reach 1Pa with the three-stage filtration system.

Q3: What are the motor specifications?
A: Insulation Class F, Protection Grade IP55. The motor features soft start, wide constant torque range, and stable flow throughout operation.

Q4: Does it require frequent maintenance?
A: No. The iron pipe system is completely leak-free and maintenance-free. The oil-gas separator features easy filter replacement, reducing maintenance costs significantly.

Q5: What happens during an emergency shutdown?
A: The normally open solenoid valve automatically closes to prevent oil injection, protecting both the equipment and operators.

Q6: How does the controller help operators?
A: The intelligent color touch screen shows clear graphics, maintenance reminders, fault alarms, and safe shutdown warnings—minimal manual input required.

Q7: Can it handle harsh working conditions?
A: Yes. The iron oil and air pipe system resists high temperature, low temperature, and high pressure, making it suitable for demanding industrial environments.

Q8: How does the cooling system perform?
A: Large heat exchange area design effectively prevents overheating, reducing oil emulsification and coking for longer service life.
