Hydraulic Motor Speed / Torque

[Earl Weiss]

Where can I find a speed / torque chart for Char Lynn and Parker Hydraulic motos.

Here is the problem. Had a 4 brush Slant Unit each brush plumbed seperately to a 4 bank AVW power pack. Speed controls have a 3/8 inlet. Each speed control is supplied from the flow divider with 1/2" SS Tube.

Used same 4 Bank pack - only 2 Banks used, with one bank each operating a pair of Sonny's wraps plumbed in series. Closed off 2 spare speed controls -not bypassing- and cranked down the torque on the 2 in use - not bypassing. At other locations, Wraps - Belanger and AVW plumbed in Series. with no issues. Would like to Get Sonny's wraps to spin a little faster for fast chain speeds but they have maxed out at 60 RPM - using cloth.

So, I would like to try the next faster hydraulic motor. I believe that as a motor is rated for faster speed at a given flow rate the max torque spec goes down. This woiuld be a simpler fix than plumbing each speed control seperately.

Your flow divider is designed to split the flow evenly through each bank. You need to do 2 things; what is the GPM of your Hyd pump and divide that by four to find out what the flow rate for each bank is. Blocking off 2 ports on the divider will not increase the flow rate to the 2 remaining ports. I use Char Lynn S-series motors on my wraps. 103-1004 CHAR-LYNN
