1 PVS Series Variable Volume Features Energy-saving Type with Drastically Reduced Loss NCHI-proprietary semi-circular barrel swash plate that receives pressure on its surface ensures a stable discharge volume at all times. This eliminates excess discharge volume, and enables the.8 to.7 cu in/rev psi Design is applied on PVS- to make the pump more compact and lighter, and reduce noise. Specifications effective use of power corresponding to the load cycle. This "energy-saving type" conserves energy, reduces power loss, and helps to reduce hydraulic costs. Suction Drain Silent Type That Demonstrates Its Power Quietly Proprietary low-noise mechanisms are incorporated on the shoe, swash plate, valve plate, and other locations to ensure silent operation. In particular, a semi-circular barrel swash plate stabilizes operation characteristics to ensure silent operation. odel Volume in³/rev (cm³/rev) Permitted volume at no-load adjustment Rotating speed min - peak pressure range psi psi min - min - min - 8min - in. ax. ass lbs PVS--8-E (8.) to 7 9 to to to 7 PVS---()-E. -.

Handling Cautions during Pump Installation and Piping Use flexible couplings for connecting the pump shaft to the drive shaft, and prevent a radial or thrust load from being applied on the pump shaft. For centering of the pump shaft, limit the eccentricity between the drive shaft and hydraulic pump shaft to. in, and keep the angle error within. Set the clamping length of couplings and hydraulic pump shafts so that it is within at least / or more of the coupling width. Use a sufficiently rigid pump mounting base. Set the pressure on the pump suction side to. or more (suction flow velocity within ft/sec). Raise part of the drain piping to above the topmost part of the pump body, and insert the return section of the drain piping into the hydraulic operating fluid. lso, observe the values in the following table to limit the drain back pressure to psi. Item odel Pipe joint size Pipe I.D PVS- PVS- /8" or more PVS- /" or more /8" /" Pipe length 9 9 anagement of Hydraulic Operating Fluid Use good-quality hydraulic operating fluid, and use within a kinematic viscosity range of to centistokes during operation. Use an R&O type and antiwear hydraulic fluid of ISO-VG to 8. The optimum kinematic viscosity during operation is to centistokes. The operating temperature range is to 9º F. When the oil temperature at startup is º F or less, warm up the hydraulic pump by low-pressure, low-operation speed operation until the oil temperature reaches F. Provide a suction strainer with a filtering sure to provide a return line filter of grade tank. (When the hydraulic pump is used at a high pressure of psi or more, or less. anage the hydraulic operating fluid so that contamination is maintained at class NS or lower. Use hydraulic operating fluid within an operating ambient temperature of to º F. (continued on following page)

2 Caution at Startup NCHI-proprietary efore you start pump operation, fill the pump body with clean hydraulic operating fluid via the lubrication. odel Injection amount cu in PVS--8 PVS--, 8 PVS--, 9 n unload is required when the motor is started under condition WYE.Delta Start. Consult your agent regarding the circuit. ake sure that the pump operates in the direction of rotation the same as that indicated by the arrow on the pump body. Explanation of odel PVS N ( ) ir entering the pump or pipes may cause noise or vibration. t startup, set the pump discharge side to a no-load state, and operate the pump in the inching mode to release any air in the pump or pipes. Provide an air bleed valve in circuits where it is difficult to release air at startup. How to Set and Volume The default pump discharge volume is set to "maximum" and default discharge pressure is set to "minimum". Change the discharge volume and discharge pressure settings according to your particular operating conditions.

The discharge pressure can be adjusted by external pilot pressure. The discharge volume can be adjusted manually. -pressure, -flow rate control type The discharge volume changes in two stages by the pump's built-in sequence valve.
