Frequently asked questions about HMGP-303S :

Is this lubrication pump suitable for 220V auxiliary circuits on CNC machines?
Yes, this reference is specified as a 220V electric lubrication oil pump. Always confirm whether your machine uses 220V AC or DC and match the connector and wiring standard used in the cabinet.

What does the 4L tank size mean in day to day maintenance?
The integrated 4 liter reservoir mainly affects how often operators need to refill oil and how stable the supply remains between maintenance rounds. It is also an easy way to confirm you are ordering the same capacity as the existing pump package.

Can HMGP-303S be used as a drop-in replacement for a failed lube pump?
In many field replacements it is used that way, but the practical match depends on voltage, mounting footprint, and how your lubrication lines connect. If you share photos of the existing unit and nameplate data, cross-checking is usually straightforward.
