Adixen™ (Pfeiffer^®) ACP Series Multi-Stage Roots Vacuum Pumps

Models:

SD versions (ACP 15 / ACP 28 / ACP 40)

The ACP SD version designed for applications that require pumping of clean (dust-free) and non-corrosive gases. The standard pumps are equipped with a gas ballast equipment in order to improve the pumping of light gases and to avoid the condensation of steam inside the pump. Three gas ballast options are available.

CV (condensable vapors) versions (ACP 28 / ACP 40)

The CV-version is specially designed for avoiding vapor condensation inside the pump block. This occurs through: A high gas ballast throughput for heating up pumps and diluting condensable gases. A silencer with drain screws for releasing liquid at the lowest point of the exhaust. Flushing gas injection to protect the ball bearing and the shaft seals. The CV version has a water vapor capacity of up to 1,000 grams per hour.

CP (gas recirculation) versions (ACP 28 / ACP 40)

The CP version is best suited for rare gas recirculation, where process gases are separated from the air and other gases. It is achieved by adding an extra port to allow pumping inside the gearbox casing and removing undesired gases. The standard usage is to pump through all ports, fill the pump with the recirculating gas, and isolating the gas ballast casing port.

Features:

Ideal replacement for scroll and oil-sealed pumps
Air cooling - No installation and operational costs for water supply
Frequency converter - Hour meter, remote operation mode (RS-485, dry contacts), multiple rotational speed selection (power saving, noise reduction, adaptation to application cycle)
Several gas port options - Purge gas, gas ballast, other specific ports according to application
Universal power supply - Wide voltage supply 50/60 Hz single-phase and three-phase
Standards - Compliance with CE standards, UL/CSA certified, SEMI S2 certified

Applications:

Electron microscopes
Surface analyzers
Leak detectors
Mass spectometers
Optical spectrometers
Particle accelerators
Turbo pumping stations
Laboratories
Lamp manufacturing
Vacuum coating
Cryo pumps regeneration
Plasma cleaning
Drying
Load-lock
