1.KCB Serial gear pump has a relief valve; as the bearings were mounted interiorly, it can only used to delivery lubricant liquid.
Lip seal and mechanical seal are available as shaft seal.
Capacity: 0.4-580 m3/h
Pressure: 0.33-1.45MPa
Viscosity:5-106cst
Temperature: ≤300℃
 

2.NHG Serial gear pump has a relief valve; as circular gear is adopted, the pump operated smoothly with low noise, high efficiency and long life; stuffing seal and mechanical seal are available as shaft seal.
Capacity: 0.25-30m3/h  Pressure:0-1.6MPa
Viscosity: 5-1000cst   Temperature: ≤80℃
 

3.NHGH Serial gear pump has a relief valve; as circular gear is adopted, the pump operated smoothly with low noise, high efficiency and long life; stuffing seal and mechanical seal are available as shaft seal.
Capacity: 0.25-30m3/h  Pressure:0-2.4MPa
Viscosity: 5-1000cst   Temperature: ≤80℃
 

4.VG serial gear pump is vertical mounting; as circular gear is adopted, the pump operated smoothly with low noise, high efficiency and long life; stuffing seal and mechanical seal are available as shaft seal.
Capacity: 0.25-30m3/h  Pressure:0-0.6MPa
Viscosity: 5-1000cst   Temperature: ≤80℃
