Hurco KM3P Injectors or Restrictors

[kc8jyr]

Hello again,
On a KM3P, can someone tell me if the way lub oil outlets are injectors or metering units/restrictors?
If they are injectors, I don't think they can have a constant pressure.
I have put an older good constant pressure way oiler unit on the mill and can not get oil to flow.
Thank you

Metering units use the high pressure lube pumps, restricters use the low pressure ones. Low pressure pumps are the type with the plunger that automatically goes up and down. High pressure pumps with metering units run about 200 psi, and only oil when the pump shuts off. They are not made to run continuous. All our old hurcos are gone, otherwise I would take a look. I'm sure bloke will know.

They are high pressure Polydropsa injectors.
