What are the common parameters of the Niigata vane pump UVN series?

Thread Content

The Nippon UVN series of vane pumps is one of the most widely used series among Nippon’s vane pumps. Like other series, the UVN series also includes a variety of models; therefore, when making a selection, it is necessary to be familiar with the parameters of the Nippon UVN series. Here, we provide a detailed overview of the common parameters of Nippon’s UVN series vane pumps. Features of the Niigata UVN series vane pump products: 1. High efficiency and energy savings: This vane pump features high efficiency at low pressures; by reducing external oil leakage, it achieves optimal pressure balance, which further reduces heat generation and improves efficiency. Therefore, it can achieve effects such as energy savings for oil pumps and improved processing precision. 2. Light weight and compact design: By designing the pump and motor as a dedicated combined unit, it features a light weight and compact size, making it easy to operate and thus expanding its range of applications. 3. Low noise and long service life: Since the oil pump and motor shaft are connected using special connectors, it is not affected by shaft vibrations or misalignment of the shaft core, resulting in lower noise levels. Furthermore, the structure ensures that this connection area is constantly lubricated by oil, which prevents frictional wear on the bearings and extends their service life. The common models of the Niigata UVN series vane pumps are as follows: UVN-1A-0A2-0.7(1.5)-4-11 – Displacement: 8.1; Pressure range: 1.5–4.0 {15.3–40.8}. UVN-1A-0A3-0.7(1.5)-4-11 – Displacement: 8.1; Pressure range: 3.5–6.0 {35.7–61.2}. UVN-1A-0A4-0.7(1.5)-4-11 – Displacement: 8.1; Pressure range: 5.5–8.0 {56.1–81.6}. UVN-1A-1A2-1.5(2.2)-4-11 – Displacement: 16.1; Pressure range: 1.5–4.0 {15.3–40.8}. UVN-1A-1A3-1.5(2.2)-4-11 – Displacement: 16.1; Pressure range: 3.5–6.0 {35.7–61.2}. UVN-1A-1A4-1.5(2.2)-4-11 – Displacement: 16.1; Pressure range: 5.5–8.0 {56.1–81.6}
