Lubrication; Connect The Dry Pumping System To The Vacuum/Exhaust System - Edwards GXS Series Instruction Manual

▪ Dry pumping systems with skids are provided with four off mounting holes in the
floor mounting plates as detailed in the installation drawings.
▪ All dry pumping systems can be secured by fitting the bolts or studs (not supplied)
through the mounting holes in either the mounting plates or seismic restraints.
Use M16 (5/8 inch) bolts with shakeproof washers or other suitable anchor bolts of
the same size.
▪ Ensure that the bolt size and spacing is adequate for the loads anticipated and the
strength of the floor or frame.
▪ To locate the pump directly on the floor, use a concrete foundation with a mass of
at least 1.5 times the mass of the pump. Ensure that the length and width of the
foundation extend at least 100 mm (4 inches) beyond the dimensions of the pump.
▪ If vibration transmission is a concern, vibration isolators (not supplied) should be
fitted between the mounting plates or seismic restraints and the bolt or stud.

3.2 Lubrication

The dry pumping systems are given a charge of oil before leaving the factory.

3.3 Connect the dry pumping system to the vacuum/exhaust system

WARNING:
Pipe the exhaust to a suitable treatment plant to prevent the discharge of dangerous
gases or vapours to the surrounding atmosphere.
WARNING:
Do not operate the dry pumping system with the exhaust pipeline blocked. If the
exhaust pipeline is blocked, the dry pumping system can generate exhaust pipeline
pressures of up to 10 bar (10 x 10
15 bar (15 x 10
if the inlet is instantaneously exposed to atmospheric pressure when the pump is
running and the exhaust is blocked.
WARNING:
Do not touch the pump exhaust and check-valve (if fitted) while the pump is running
since the temperatures of these parts cause burns. These parts will remain hot after
the pump has stopped.

5
Pa). Note that a pressure spike up to a maximum
5
Pa) can be generated in the exhaust pipeline for less than 0.5 seconds
