Can I upgrade Classic Head Pump 1290 G4204A to Easy Maintenance Head pump?

Yes, this is available. You will need to get in touch with the sales team to order the upgrade to Easy Maintenance: G4222A Easy Maintenance Upgrade for 1290 Quaternary/Flexible Pump.

thank you for your inf. So, it just G4222A that don't need to change a new dpump  driver?

For Long Life Pump heads, the pump drives need to be changed. This is also available as a product: G4268A Long Life Upgrade fro 1290 Quaternary/Flexible Pump.

DoKien : here is a technical note on how to install EM pump head. Part number G7104-68100 (or G4222A) is not orderable online so like kbusch mentioned, you will need to reach out to your Agilent local support. 

I know with long life Pump heads, I must need a new Pump Drives, but with EM head, 

Do I need to replace the pump drives with new ones or keep the Pump drives of the Classic type?
And I have one more question that in the information displayed on Lad Advisor, 
my current pump is Drives: Classic, Head: Classic. So when replacing Pump Heads of type EM, will the information automatically be updated to Pump Heads: EM? 
What part of this information is the pump using to identify it?

No, the easy maintenance pump heads use the same drives as classic. The drive will read the same and the EM will read the pump head part number G4204-60300.

Thanks Kbusch, 

I know that only Head Pump Classic released after 2013 can upgrade the Head pump EM for proper use. Are you sure my Pump Drive above will fit the Head Pump EM? Also, I want to ask more, if I use Head pump with code G4220-60300/60310 (EM Head pump Binary) is it suitable?

Yes, drives can use EM pump heads. No, Binary pump heads cannot be used on the quaternary pumps.
