Service, spares and accessories

7.4.7

Outlet mist filter

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

7.4.8

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

7.4.9

Vibration isolators

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.

7.4.10

Pump inlet or outlet NW25 adaptor

This is a 

3

8

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

fitted to the pump-inlet or the outlet-nozzle fitted to the pump outlet are removed, to adapt the 

3

8

 inch BSP thread 

to NW25.

7.4.11

Solenoid operated gas-ballast control valve

The valve provides remote or automatic on/off control of gas-ballast. The valve can be connected to shut-off ballast 
to prevent the return of air to the vacuum system when the pump is switched off.

7.4.12

Solenoid operated pipeline valve

Fit the pipeline valve between your vacuum system and the pump inlet to provide additional system protection when 
the pump is switched off.
