3. Model Coding System

1. Pump Series: PVH
2. Maximum Geometric Displacement: 057/063/074/081/098/131/141 (corresponding to displacement values)
3. Design/Application Type: Blank = For mobile applications; QI = Low-noise design for industrial applications
4. Mounting Flange (Driver End): C = SAE “C” 4-bolt type (SAE J744-127-4); M = ISO 3019/2–125B4HW (only for PVH57 and PVH74)
5. Shaft Rotation Direction (Viewed from Driver End): R = Clockwise; L = Counterclockwise
6. Configuration: Blank = Non-thru-drive (single pump); A = Thru-drive pump with SAE “A” 2-bolt rear flange; B = Thru-drive pump with SAE “A” 2-bolt and 4-bolt rear flange; C = Thru-drive pump with SAE “C” 2-bolt and 4-bolt rear flange
7. Pump Design Number: 10 (design numbers 10-19 have unchanged mounting connection dimensions)
8. Pressure Compensator: C = 70-250 bar (1015-3625 psi) (standard); CM = 40-130 bar (580-1885 psi) (optional QI type); IC = Industrial control with 290 psi differential pressure
9. Factory Setting of Pressure Compensator: 25 = 250 bar (3625 psi) for Type C; 7 = 70 bar (1015 psi) for Type CM (in 10 bar increments)
10. Additional Control Functions: Blank = No additional control; V = Load sensing (290 psi differential pressure); T = Torque limiter; VT = Load sensing + torque limiter
11. Factory Setting of Torque Limiter: Expressed in 10 bar increments (e.g., 8 = 80 bar / 1160 psi; 18 = 180 bar / 2610 psi)
12. Control Design Number: 31 = For C, CM, C**V, or IC control; 13 = For C**T control; 14 = For C**VT control
13. Special Feature Suffix: 027 = Combined 2-bolt/4-bolt mounting (SAE “C”, except PVH131); 031 = Thru-drive SAE “A” seat cover; 041 = Without housing-to-inlet overflow valve; 057 = Shaft upward operation (vertical mounting); S = Adjustable maximum displacement stop (only for non-thru-drive and non-torque control types)

4. Key Features & Advantages

• Versatile Design: Available in single pump, thru-drive arrangements, various drive shafts and control options, adapting to any application with cost-effective installation.
• Heavy-Duty Durability: Proven components in a compact housing ensure long service life at high performance levels; heavy-duty bearings and shafts minimize internal deformation and wear.
