Used EDWARDS RV3 #9224417 for sale

EDWARDS RV3 is an oil-sealed rotary vane vacuum pump designed for use in laboratory, industrial, and scientific applications. EDWARDS RV-3 is a single-stage, air-cooled vacuum pump that operates on direct current and offers superb vacuum capability with an ultimate pressure of 0.25 mbar. The pump features a simple, direct-drive design, with a powerful 2.2 kW electric motor driving the pumping element. RV 3 is quiet, efficient, and reliable, offering excellent performance in a variety of applications. RV3 is constructed with a three-vane rotor and a stator, which are made from a robust alloy of steels and non-ferrous metals. The stator hosts three stationary vanes, which contact the rotating vane at their trailing end and define an area of sealed chamber volume that increases and decreases with rotation. This creates two volumes: one which is connected to the inlet port, and one to the exhaust port. The changing chamber size creates a vacuum in the inlet volume, and the exhaust pressure is maintained by eddy current losses in the exhaust port. The seals between the rotor and the stator ensure that no air enters the pump from the outside. EDWARDS RV 3 has an oil-sealed design for reliable and long-lasting performance. It features a pre-installed oil reservoir that can hold enough oil to operate the pump for an extended period. The lubricating oil also helps cool the pump, ensuring that it runs at the right temperature. The pump's oil-sealed design also prevents contamination from entering the pump, allowing it to produce a higher vacuum. RV-3 has an inlet and outlet connection set up to draw in and expel air. The air is expelled through the exhaust valve in the port, and the pump does not require any additional filtration or lubrication. EDWARDS RV3 is a dependable and quiet rotary vane vacuum pump with a high-quality build and excellent performance. It is ideal for a variety of applications, from laboratory work to industrial processes, and will provide many years of reliable service.
