Overview Edwards RV pumps have become the industry standard for scientific primary pumping applications. RV pumps are uniquely capable of delivering high or low throughputs with high ultimate vacuum. This, combined with ultra-low noise levels, makes them ideal for a wide range of applications including GCMS and other small bench top type applications. All pumps are approved to UL standards by an external test house. Edwards has a global network, providing world-wide support for product applications and service. Supplied with: 1 litre of Ultragrade 19 oil, inlet filter and O-ring. Fomblin must be purchased separately for PFPE RV pumps.
