Oil Rotary Vane Pumps Two-Stage
Rotary vane pumps are considered wet, positive displacement pumps, with the term āwetā denoting that the gases being pumped are exposed to oil. The significant characteristic of oil sealed rotary vane (OSRV) pumps is the use of oil as a sealant and coolant.
Two-stage rotary vane vacuum pumps use a two stage compression offering high pumping speeds combined with low ultimate pressure. They are widely used in industrial, chemical, pharmaceutical, and food industries.
E2M Two Stage RVP
EM series pumps are rugged mechanical oil-sealed pumps with speeds ranging from 0.7 to 275 m3/hr (30 to 206 CFM). Compact and quiet, they feature advanced lubrication circuits, high reliability, and accessories to suit specific application needs.
EM products serve two major application sectors.
In scientific and laboratory applications, the E2M0.7-2.5 and E2M18/28 are the ideal partners for your turbomolecular pump.
In Industrial applications, E2M18/28, E2M40/80 and E2M175/275 offer very robust solutions in demanding applications.

Features and Benefits
- Designed for reliable and long term operations in both labs and Industrialenviornment
Edwards product code: A36704940
Water-cooling required
Your pump is water cooled. We recommend that you use a thermostatic controlledĀ valve to regulate water flow. This will ensure optimum pump working temperature,Ā maintain economies in water use, and provide assistance with gasāballast protection.Ā The thermostatic control valve is an accessory, refer to Service, spares and accessoriesĀ on page 43.
Refer to Service, spares and accessories on page 43 for details about vibration isolatorsĀ and other recommended accessories.
Connect the pump to the cooling water
Connect the two 3/8 in. BSPP/T internally threaded connections to the cooling water supply. The maximum pressure that can be admitted to the cooling circuit is 3 bar and the recommended minimum cooling water supply flow rates at 20 Ā°C are: E2M275 120 l h-1
Your pump will reach optimum operating temperature and will operate more efficientlyĀ if the temperature is controlled by the TCV300 thermostatic control valve.
