[PSUBS-MAILIST] FW: VBT pump

[Alan James via Personal_Submersibles]

Hugh,Years ago I bought a Karcher 36V battery powered car wash water blaster with a piston pump that is touted as being corrosion resistant.I think the pressure was 750psi.I saw this item with a higher psi but not sure if its corrosion resistant.https://www.kaercher.com/int/overview-battery-products.html
It may be a product you mightn't have thought of.Ali may have the pump for this unit.Alan

Hi Guys

  

What make of pump is best for VBT water transfer in/out for 250 psi 1.5 kw.

I am looking at a gear pump 1.5kw Oberdorfer 944 Bronze.  These are only rated for 10 bar.  I tried an hydraulic gear pump 30cc where I had a stainless and bronze gear set made up but the aluminium body corroded form the trials and I just found that they had used steel backed sleeve bearings.

  

Regards,

Hugh
