Following standard features provided with the pump:

Vacuum relief valve (In case of vacuum pump)
The relief valve is designed to open at a predetermined set pressure to protect the pump from damage.
When the vacuum level is exceeded, the relief valve opens and allows air to enter the pumping
chamber. This has the effect of internal cooling.

Intake filter (In case of overpressure pump)
Intake filter prevents foreign material from entering the pump. Abrasive, bulky material will damage
the pump's internal parts and could cause catastrophic failure.

Silencer (Extra inlet silencer in case of overpressure pump)
The pump inlet and discharge can be noisy. The pump is equipped with an outlet silencer.
For the overpressure pump an extra inlet silencer is

Pressure Safety valve (In case of overpressure pump)
A pressure safety valve automatically releases air from a pump, when the pressure exceeds preset
limits.
The following features are available as an option:

Humid Option (In case of vacuum pump)
'Standard' and 'Humid' versions are available dependent upon the harshness of the application.
The harsh applications, generally wet application need more protection for the pump. 'Humid' version
contains advanced corrosion resistant wetted parts.
In addition to this, pump is provided with inlet liquid separator, condensate drain facility and corrosion
resistive coating to the exhaust to withstand the harsh applications.
