Brief introduction
The medium EM series pumps are robust and durable mechanical seal pumps with flow rates of 18 and 28 m³/hr. These pumps are compact in design, operate quietly, feature advanced lubrication circuits, offer high reliability, and come with a variety of accessories to meet specific application requirements.
Edward E2M28 Oil Sealed Scroll Vacuum Pump Edwards Vacuum Pumps
Overview
The EM series oil seal rotary pump, renowned for its high ultimate vacuum, high pumping speed, low operating noise, and capability to handle steam, has become the industry standard for laboratory and light industrial applications.
The E2M28 pump is a two-stage, direct-connected vane pump. It is sealed for reliable and long-term operation in both laboratory and industrial environments. The pump is a free-standing unit, powered by a single-phase or three-phase (four-pole) motor via a flexible coupling.
With product provided: Ultragrade 19 oil, NW25 O-ring and centering ring, lifting plate. Fomblin® must be purchased separately for the PFPE pump.
