Parker Gold Cup IE (Intelligence Enabled)

Parker Gold Cup IE

Parker Gold Cup IE

Parker introduced Gold Cup – IE (Intelligence Enabled) pump.

In general, this is just the new option “E” at the secondary control option for the “9A” electro-hydraulic stroker as the primary control. This option combines the robust design of Gold Cup pump technology with the intelligence of operational sensors and analytics.

Example model number:

P11P3R1C9AEB00

In my opinion, this option is not for every application, because most sensors are not required for regular tasks. But probably there are exist some sensitive applications where all components should be monitored in real-time (where the high cost of downtime) for detecting failure before it occurs.

Rexroth A4VG clones

Semi-closed hydraulic circuits

Have you ever heard about the semi-closed hydraulic circuit?

The idea is to use open loop pumps in closed loop circuit. In the latest eighties, Mannesmann Rexroth (yes, that time Mannesmann yet!) even offered pumps A4VSH, especially designed for semi-closed circuits.

Bosch Rexroth A4VSH pump

Bosch Rexroth A4VSH pump, from catalog RE92110/01.89

The main difference between closed loop pumps and semi-closed loop pumps was in addition block mounted to the ports A and B with check valves which let to supply suction flow from the tank, while mainstream comes from the motor to pump’s suction port:

Since that time Rexroth still builds A4VSH, but there are a limited number of sizes and options available and its no longer a mainstream published option.

But to make a semi-closed loop you do not need some special pump, it’s really easy to turn most standard open loop pump into a semi-closed loop circuit. Of course, you have to have some knowledge about the application and actuators before trying to apply it. If the pump does not have an integrated boost pump and check valves these are commonly added via an external gear pump and external check valves.

Here is the simplest example of the semi-closed circuit schematic where a regular open loop pump with LS control is involved to run two motors with independent proportional control of their speeds:

Just have been gotten an interesting link from Parker distributor for their Gold Cap Pumps interactive online software:
https://divapps.parker.com/divapps/hpps/gold-cup-pump/

Here you can:

  • take a look at how different valves work internally in the pump;
  • check schematic for each pump’s option and size;
  • learn the terminology of pump internal components;
  • watch the video and download PowerPoint presentation about these pumps;
  • at the bottom of this software, you can find a link to the eConfigurator.

My notes:

  • Gold Cap pumps are pretty complicated, so any additional info like this is always helpful.
  • It will be awesome if the pumps schematics can be downloaded in DXF format to integrate into my projects.
