APPLICATIONS:

Moisture Trap

Inlet Dust Filter
Vacuum Gauge with Regulator
Trolley for small pumps.
Use Oil :ENCLO-46(H.P.) SAE 30 or equivalent Vacuum Duty oil.
Model ALM-300 II and above, are provided with water cooling Jacket.

Non Return Valve:
It is rubber diaphragm type spring loaded valve ,which prevents back-flow of oil to the system as soon as the pump stops. These can not be used to hold the vacuum in the system for longer period.

Air Ballast:
This is a vent pipe introducing air before actual compressions which eliminates condensation of the sucked vapor , thereby avoiding contamination of oil.

Air admittance Valve:
It is electromagnetic solenoid type which admits air into the system as soon as the power supply fails . This prevents backflow of oil to the system.

ACCESSORIES

These are oil immersed rotary vane type pumps The rotor with two spring loaded vanes is mounted eccentrically in the stator .As the rotor rotates, the vanes sweep crescent shaped air space twice in each revolution .The built-in non return valve prevents back flow of air.
