Vibration Isolators; Oil Drain Extension; Pump Inlet Adaptor; Flexible Bellows - Edwards E2M28 Instruction Manual

10.3.8 Vibration isolators

The vibration isolators reduce transmission vibration and noise when the pump is floor
or frame mounted and help to reduce strain when the mounting area is uneven.

10.3.9 Oil drain extension

Fit the oil drain extension between the oil drain port on the pump and the oil drain-plug
to make the drainage of oil from the pump easier.

10.3.10 Pump inlet adaptor

This is a NW25 to 28 mm bore tube adaptor, supplied with connection hardware. Attach
this adaptor to the NW25 pump-inlet to connect 28 mm bore plastic or rubber tube.

10.3.11 Flexible bellows

Use flexible bellows to connect the pump-inlet to the vacuum system. We recommend
the use of bellows when using vibration isolators.

10.3.12 Pump outlet adaptor

This is a 3/4 inch BSP to NW25 adaptor. Use this adaptor when removing the hose
adaptor supplied fitted to the pump outlet to adapt the 3/4 inch BSP thread to NW25
pump inlet.
