Vacuum Pump - Not Able to Achieve Required Suction Pressure ( Vacuum )

KK
If the pump is not producing sufficient vacuum. the possiblities are
a) The pump is too small , but if you replacing other  pump with the same rating ,then this should not be the problem

b) The flow of the the service liquid is too low , increased the flow of service water to twice the rated value

c) Temperature of service liquid is  high ( not so likely in palm oil mill )

d) Air leakage in the system

e) Leakage in Mechanical seal

f) Internal Corrosion , but if new pump then this is unlikely

Checking  your pump rating and confirm if is correct
If correct rating .focus on (b) to ( e )

Other mechanical fault , clearance between impeller and plate , or casing
