PVH piston pump
1.Displacement Range:
57 = 57.4 cm3 / r (3.5 in3 / r) 63 = 62.7 cm3 / r (3.84 in3 / r)
74 = 73.7 cm3 / r (4.5 in3 / r) 81 = 81 cm3 / r4.9 in3 / r)
98 = 98.3 cm3 / r (6.0 in3 / r) 106 = 106.5 cm3 / r (6.5 in3 / r)
131 = 131.1 cm3 / r (8.0 in3 / r) 141 = 141 cm3 / r (8.64 in3 / r)
2.Design/application
Blank for the design of the use of = walk
QI = for industrial use of low noise design
3-Iinstallation flange
C = SAE "C" 4-bolt type (SAE J744-127-4))
M = ISO 3019/2-125 B4HW (only for PVH57 and PVH
4-Rotation
R = clockwise
L = counterclockwise
5-Configuration
Blank = single pump
S = maximum displacement can be adjusted
6-Lord oil mouth
F = SAE 4-the flange bolts oil mouths
M = SAE 4-the flange bolts oil mouths, installation with a metric thread
7-Shaft stretch type, rely on the motor
N = ISO3019/2-flat key short straight E32N axis
1 = SAE "C" flat key axis (J744-32-1)
2 = SAE "C" spline shaft and tooth (J744-32-4) 12/24 section size, 30 ° pressure Angle involute, ping tooth root
3 = SAE "CC" spline shaft and tooth (J744-38-4) 12/24 section size, 30 ° pressure Angle involute, ping tooth root
12 = SAE "D" 13 teeth spline shaft (J744-44-4) 12/24 section size, 30 ° pressure Angle involute, ping tooth root
13 = SAE "CC" flat key axis (J744-38-1)
16 = SAE "D" flat key axis (J744-44-1)


Variable straight shaft piston pump,big capacity,high performance ,it is suitable to the industrial and construct mchinery.
