Outlet mist filter
The outlet mist filter separates and traps oil droplets to prevent oil mist discharge from the pump outlet.
7.4.8

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. The pack includes an oil drain extension tube for use when oil is gravity drained.

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

8
inch BSP to NW25 adaptor, supplied with connection hardware. Use this adaptor when the NW10 adaptor

8
inch BSP thread
to NW25.
