Hangzhou Hesar Hydraulics Co.,Ltd

Introduction:
1.These cost-effective pumps provide volumetric efficiencies of more than 90% and sound levels as low as 62 dB(A) with operating
pressures to 207 bar(300psi)
2.Low noise characteristics inherent in intravane design enhance operator comfort
3.Twelve vane system provides low amplitude flow pulsations resulting in lowsystem noise characteristics
4.The cartridge kit design offers fast and efficient field serviceability. The cartridge is independent of the of the drive shaft,allowing
for easy change of flow capacity and servicing without removing the pump from its mounting.
