q High e�ciency, high pres-sure operation
The unique pressure regulator andpressure balance mechanism, plus theexclusive three-point ring support sys-tem has improved performance duringhigh pressure operation. The pumpoperates with high e�ciency and sta-ble performance up to a maximum of140kgf/cm 2 (2000 psi).
w Low vibration and noiselevels
The new mechanisms reduces vibra-t ion and noise levels . Of part icularnote is the unique and exclusive three-point support system which uses, aregulating piston and a bias piston toeliminate vibration. The mechanism,
t o g e t h e r w i t h i m p r o v e m e n t s t o t h eshape of the inlet and outlet ports andhigh performance journal bearings,has reduced the noise level duringoperation.
e Fast response The ring stopper mechanism serves toallow swift response whether in start-ing, stopping, or with load �uctuations,for high precision operation.
r Stable discharge with sharpcut-o� characteristics
A revolutionary pressure compen-s a t o r t y p e p r e s s u r e r e g u l a t i o nmechanism provides, stable sharpcut-o� characteristics. The com-pensator serves to provide stable
and constant volume through ourthe pressure ranges.
t High e�ciency operationwith reduced power loss
E�ciency has been improved withthe new mechanisms and Nachi'shigh precision machining technolo-gy. Power loss has been reduced,expecially during dead-heading.
y Easy adjusting in mainte-nance and handling
Maintenance is easier due to thepositioning of the pressure adjust-ing mechanism and the volumeadjusting mechanism on the sameside of the pump.
