Hangzhou Hesar Hydraulics Co.,Ltd

Introduction:
1.Adopt the structure of floating side plate supporting with its function of automatic tolerance compensation,which helps to get
pressure balance and high preformance under high rotation speed and high pressure.
2.Adopt bimetal flexible material for side plates,which dramatically improves the engagement performance of the gears and thus
makes the pump working better and longer.
3.The cartridge kit design offers fast and efficient field serviceability. The cartridge is independent of the drive shaft,allowing for
easy change of flow capacity and servicing without removing the pump from its mounting.
