PVS Series Piston Pump Thru Shaft Series

The PVS Series Piston Pumps offer multiple pressure compensation options and multiple spline and key shaft options, enhancing its versatility. They feature low friction Nachi bearings that guarantee viability, coupled with high operating efficiency to lower power consumption and reduce heat generation. The semi-circular swash plate design ensures a stable discharge volume, minimizing power loss. Additionally, the 11-piston design reduces flow ripple, thereby decreasing noise levels. 

Allowable Torque

Model Number Naming Structure

Calculation of Torque

Equation:

Torque (in-lbs) = Pressure (psi) x Displacement (cipr) ÷ (2π)

Example:
Total allowable torque for this pump is 928.80 in-lbs PVS-1B-16/22N*-K-E5737B (Front Pump)
Pressure Setting: 3000 psi Displacement Setting: .50 cipr Equation: (3000 psi x .50 cipr) ÷ (2π) Result: T = 238.73 in-lbs

PVS-1B-22N-E13 (Rear Pump)
Pressure Setting: 750 psi Displacement Setting: 1.00 cipr Equation: (750 psi x 1.00 cipr) ÷ (2π) Result: T = 119.37 in-lbs

Total Torque = 119.37 in-lbs + 238.73 in-lbs = 358.1 in-lbs

Notes:
Total torque is dependent on both the pump size and shaft style All torque and shaft specification can be found in the PVS brochure
