Used VARIAN HS 602

Agilent Varian HS 602 Smart Pump High Vacuum Pumping Station

The Agilent HS 602 is a "Smart" dual-stage, oil-sealed rotary vane vacuum pump engineered for high performance and energy efficiency. It is essentially an enhanced version of the robust DS 602 pump, upgraded with an intelligent, microprocessor-controlled frequency inverter. This key innovation allows the pump to deliver optimal and consistent performance across a worldwide range of voltages and frequencies.

Designed to be environmentally friendly, the HS 602 features reduced power requirements and a low start-up current, which eliminates the need for special circuit breakers. Its "Smart Pump" capabilities allow it to address the demanding requirements of applications like mass spectrometry and electron microscopy by providing high-capacity pumping speed within a minimal footprint.

The pump's simple and highly reliable design ensures high pumping stability for light gases, low noise operation, minimal oil backstreaming, and a long service life. Key operational features include a forced oil circulation system for reliable lubrication, an anti-suckback valve to protect the vacuum system from oil contamination during shutdowns, and a gas ballast valve for pumping condensable vapors.

Key Features and "Smart" Technology Advantages:

• Innovative Inverter Technology: A microprocessor-controlled frequency inverter delivers consistent performance regardless of input voltage and frequency, provides high starting torque, and significantly reduces inrush current.

• Energy Efficient: The "Smart" technology optimizes energy consumption, lowering operational costs.

• High Performance: It offers a high pumping speed and achieves low ultimate pressure suitable for a wide range of scientific and industrial applications.

• Global Compatibility: The pump's motor is designed to operate on virtually any voltage and frequency combination found worldwide, simplifying inventory and logistics.

• System Protection: An integrated anti-suckback valve isolates the pump from the vacuum system in the event of a power failure or shutdown, preventing oil contamination.

• Robust and Reliable: Built on the field-proven design of the DS series, it is known for its durability, low noise, and long operational life.

Condition:

This pumping station is in good used condition. It has been tested to power on, and the start-up sequence completes successfully. The DS 602 backing pump engages, and the turbomolecular pump spins up to its full operational speed without errors. Cosmetically, it shows normal signs of use in a lab environment (please see photos). It is a complete, ready-to-work high-vacuum solution.

Shipping & Handling:

The oil will be drained from the DS 602 backing pump before shipment to comply with all shipping regulations. The buyer is responsible for adding the correct type and amount of vacuum pump oil (e.g., Inland 19) before operation.

The unit will be professionally packaged, bagged, and securely strapped to a pallet to ensure safe delivery.
