HPU Unit

I want to know about the Hydraulic Power Unit so can you please provide me some information about it and an image of it.

[Shaleen]

The Hydraulic Power Unit (HPU) is used to test various subsea tooling. The unit has four lifting points.

Here is the information about it:

Technical data / Specifications
Dimensions (overall) Length 56 in Width
42 in Height
42 inWeight (air 1,500 lb)

Here I have uploaded the image of it. You can get the image after downloading it from here.

Hey buddy; I want the basic information regarding Hydraulic power units so will you please provide me?

Hydraulic power units provide pressurized flow to hydraulic motors, cylinders, and other hydraulic components.

It is differ from pumps, as an HPU contains a fluid reservoir, multiple pump stages and coolers to keep fluid at a safe working temperature.
