Documents & Support Overview
Edwards E2M175 series two stage oil sealed
rotary vane vacuum pumps are renowned for their
high ultimate vacuum, rapid pumping speeds,
quiet operation and ability to handle water
vapour. These direct drive rotary vane pumps
are inherently compact and vibration free, and
with their finger-proof fan and coupling
housings they offer excellent operator
protection.
This pump is suitable for most duties and is
safe to handle non-flammable gases and vapours
within the normal operating parameters of the
pump.
Reliable system protection devices
Every pump has protection devices to prevent
oil and air suck-back into the vacuum system if
the pump stops while under vacuum. A variety of
protection devices are used, depending on the
pump size and cost, but emphasis is always
placed on reliability and simplicity. When you
use gas ballast on some of the pumps, you must
use a solenoid operated gas ballast control
valve to prevent air suck-back.
Positive Pressure Oil Lubrication
The EM pumps incorporate a well proven
positive pressure oil lubrication system which
as been developed by Edwards to ensure correct
lubrication in all duty modes and particularly
to prevent oil starvation with high gas loads.
An integral oil pump ensures that a more than
adequate oil flow is pumped throughout the
stator/rotor assembly at all times.
This oil lubrication system means that the
level of oil in the reservoir is less critical
than with other pump designs. All pumps can
operate with oil levels as low as 50-70 of the
maximum. A full length, easily visible oil
level sight glass allows you to conveniently
monitor the oil level.
Gas Ballast Facility
The EM pumps have a gas ballast valve. The
valve is used to introduce a suitable gas into
the stator during the compression stage: this
prevents condensation of vapors inside the
pump, dilutes and ejects corrosive gases and
purges the oil of gases and vapors. Therefore,
the use of gas ballast reduces oil degradation
and pump corrosion.
Low Noise Levels
The EM pumps maintain Edwards’s reputation
for quiet operation pumps with a typical noise
level of 75 dB(A).
Pumping Systems
The EM pumps, with suitable accessories, can
partner a variety of other types of pump in
vacuum systems for industry and for research. A
special feature of the E2M175S is the central
vacuum inlet which enables you to fit a
mechanical booster pump with a minimum
overhang, to create compact combination pumping
systems.
Easy Maintenance
The advanced lubrication system allows the EM
pumps to work with wide oil level tolerances,
which reduce the need to top-up the oil.
All EM pumps are constructed with internal
dowels, which reduce the need for skilled
setting of tolerances, when the pump is
dismantled. The pumps are designed so that all
key components are easily accessible. The
exhaust valve seals and oil distributor seals
are exposed after the top cover is removed. The
shaft seal can be replaced quickly without
stripping down the pump.
