Veat-002 High Vacuum Diffusion Pump System Ultimate Vacuum 2.5×10⁻⁴Pa Dual Port Kf40/Kf25

Veat-002 High Vacuum Diffusion Pump System Ultimate Vacuum 2.5×10⁻⁴Pa Dual Port Kf40/Kf25

Product Introduction

VEAT-002 adopts a semi-enclosed structure and intelligent temperature control system, integrating a No. 275 silicone oil diffusion pump (heating power 1kW) and a GS-1 rotary vane pump, and can achieve stable high vacuum (≤2.5×10⁻⁴Pa) within 20 minutes. A three-way manual high vacuum baffle valve is installed on the top of the equipment to quickly switch the exhaust path; built-in vacuum solenoid valve and gas tank (1 hour of sustained vacuum), automatically cut off the backflow when the power is off to protect sensitive workpieces. Adapt to PU quick-plug cooling water interface (200L/h flow), suitable for glass tube hot melt plugging, vacuum coating and sterilization container vacuuming.

Product Features

• High-performance exhaust system: main exhaust speed ≥280L/s, ultimate vacuum 2.5×10⁻⁴Pa, gas tank pressure maintenance for 1 hour.
• Safety protection design:

1. Automatically close the vacuum pipeline when the power is off to prevent oil vapor backflow pollution.
2. Real-time monitoring of cooling water temperature (10℃-35℃), automatic alarm for overheating.

• Flexible multi-interface: KF40/KF25 dual exhaust ports can be switched freely, suitable for DN25-DN40 vacuum bellows.
• Low noise and environmental protection: The exhaust port of the rotary vane pump is equipped with an oil mist filter, the noise is ≤55dB, and the oil mist purification rate is ≥95%.
• Industrial-grade durability: cooling fans on both sides of the rack support continuous operation in an environment of -10℃~55℃.
• Convenient movement: The metal ionization gauge is designed to be shatterproof, the whole machine weighs 105kg, and it comes standard with a universal wheel base.

International Reference Standards

• ISO 9001:2015 Quality Management System Certification ensures the reliability of production processes and components.
• IEC 60255-1 Electrical Safety Specification for Vacuum Equipment, covering insulation strength and electromagnetic compatibility testing.
• ASTM E595-07 Vacuum System Outgassing Rate and Contamination Control Standard, limiting volatile pollutants to ≤0.01%.
