Figuring Gear Pump G.P.M.
GPM @ 1000 RPM = 26 X w X (2D -L) x 
GPM @ 1200 RPM = 31 X w X (2D -L) x
GPM @ 1800 RPM = 47 X w X (2D -L) x
EXAMPLE: GPM @ 1000 RPM
D = 1.990
W = 1.738
L = 3.705
GPM = 26 X w X (2D -L) x
GPM
= 26 X 1.738 X (2.1.990 -3.705) X 
GPM
= 45.188 X .275 X .8575
GPM
=10.656  11 GPM@1000RPM
