Dekker Vacuum Technologies Oil-Sealed Liquid Ring Vacuum Pump System VMX0303KA1-20

Identify Pump Type and Requirements

Does the pump require lubrication every 1500 hours?

Lubrication Process for Maxima-K-series

Locate grease fittings on the top of each bearing housing

Use a good quality high temperature lithium based grease of #2 consistency

Consultation for Titan-series two-stage Pump HP 100 - up

Consult factory for lubrication requirements

Ensure the following items are available

Is the motor stationary and warm?

Locate the grease inlets on each end of the motor

Clean the area around the grease inlets

Replace the pipe plug with a grease fitting

Remove the grease drain plug and loosen any hardened grease

Add the recommended volume of grease using a hand operated grease gun

Inspection of Mechanical Shaft Seal

Is there any visible leakage from the mechanical shaft seal?

Measure the leakage rate from the mechanical shaft seal (drops per minute).

Determine the type of leakage observed.

Is the leakage rate within acceptable limits (weepage)?

Action Based on Leakage Assessment

Is seal replacement necessary based on leakage assessment?

Describe any actions taken or recommendations for seal replacement.

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

Is the inlet filter element clean or replaced?

Enter the hours since last inlet filter maintenance

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
