Dekker Vacuum Technologies Oil-Sealed Liquid Ring Vacuum Pump System VMX0063MA1

Identify the pump type and lubrication requirement

Lubrication Process for Maxima-K-series

Ensure the pump is a Maxima-K-series large capacity Pump HP 50 - up

Locate grease fittings on the top of each bearing housing

Use a high temperature lithium based grease of #2 consistency (e.g., Texaco Premium RB, Chevron SR1 #2)

Is the lubrication process completed successfully?

Enter the back-pressure on separator element

Is the back-pressure on separator element within 4 psig?

Change separator element if back-pressure exceeds 4 psig

Check discharge pipe system for blockage

Inlet Filter Element Maintenance

Select action for inlet filter element

Remove debris from the following areas

Ensure there is no power to the system and the pump is off

Drain the fluid reservoir using the drain valve

Drain the vacuum pump using the drain valve

Drain the heat exchanger using the drain valve

Charging the System with New Fluid

Ensure the system is at operating temperature before changing fluid

Fill the pump with oil to the shaft centerline level

Is there any visible leakage from the mechanical shaft seal?

Measure the leakage rate (drops per minute)

Determine the type of leakage observed

Is the leakage rate more than one drop per minute?

Check for abrasive particles around the seal area

Is there excessive wear on the seal faces?

Ensure the following items are available

Is the motor stationary and warm?

Locate and prepare grease inlets

Clean the area around the grease inlets

Replace pipe plug with a grease fitting

Remove grease drain plug and loosen hardened grease

Add recommended volume of grease using hand operated grease gun
