Used VARIAN V 1000 #9001189 for sale

VARIAN V 1000 is a high performance, reliable, rotary vane pump used in many laboratories and analytical systems. Its key benefit is the adaptive gas ballast technology, which allows it to be used for both rough and fine vacuum applications. It has both a direct drive and an indirect drive motor with adjustable speeds of 30,000, 35,000 and 40,000 rpms. This enables the pump to achieve maximum rotational speed when desired and yet remain efficient while operating at idle. V 1000 is designed for durability and long-term use. Its motor is enclosed in a metal housing to protect it and to increase its heat dissipation. The oil reservoir has a deep sump with a sloped lower bowl to help capture and hold oil, preventing loss of pressure and cavitation while the pump is running. The mechanical seals that connect the impeller and the rotor are made of PTFE and carbon/graphite which gives it superior sealing. The pump also has high vapor throughput and deep ultimate vacuum. The maximum throughput can reach up to 153 liters per minute and the ultimate vacuum is 13 to 19 mtorr. It uses premium grade silicone based oil which allows operation under high temperatures, making it perfect for rotary evaporators, freeze drying, distillation, and other processes requiring vacuum. In addition, VARIAN V 1000 is easy to maintain. It's designed so that the motor, the bearings, and the seals can all be replaced without needing to disassemble the pump. The oil drain is vacuum assisted and allows for quick, mess-free access for the user. Overall, V 1000 is a reliable and powerful pump that can be used in a variety of application where high vacuum and high throughput are both necessary. It's designed for durability, efficiency, and is relatively easy to maintain.
