NACHI Genuine Hydraulic Variable Pisoton Pump PVK-2B-505 for Mini Excavator main pump 

PVB-00B PVD-0B PVD-15B PVD-2B PVD-3B Nachi original Hydraulic pump

Nachi pumps has 3 kind , Nachi plunger pump, vane pump, gear pump. Nachi hydraulic pump has 3 kind Variable control model. Variable control is through the system pressure, flow, power and other parameters to control the tilt plate Angle of the pump, so as to change the displacement of the pump.There are three main control methods: constant pressure control, load sensitive control and constant power control. 

Nachi plunger pump features: 

1. High efficiency —— adopts patented technology to improve the efficiency with axial and radial pressurization, and the pressure can reach 300Mpa. 

2. Long service life —— good wear-resisting and extremely strong service life. 

3. Low noise – using modified open line, short tooth meshing design way to reduce the pulse, reduce the noise very quiet. Simple structure and easy maintenance.

Nachi Vane pump features: 

1. VDS series vane pump.VDS series vane pump has the advantages of high efficiency operation to reduce power loss, low noise, small shape, simple structure, simple operation, fast characteristics and sharp response. High effect, long life, firm structure and other characteristics.The models of VDS series are as follows: vds-0a-1a1-10 vds-0b-1a2-10 series. 

2. VDR series oil pumps have the following characteristics: stable and efficient operation at 14MPa pressure, high precision instantaneous response, high pressure area, low noise action, reduction of power loss, strong structure resistant to harsh environment. 

3. VDC series vane pump is high pressure vane pump, also can be efficient, stable high pressure operation, low vibration, low noise, quiet, rapid response and high precision action, precise characteristics, stable delivery, reduce power loss efficient operation, maintenance, operation are very simple. 

Nachi Gear pump features the same as Nachi plunger pumps.
