V series low noise intra-vane pump with high performance meets for industrial application. It is fit for variety hydraulic systems such as Plastics Injection Moulding Machine, casting machine, rubber machine, and machine tool and so on. Its main features: 1. The structural designs of intra-vane absorb impact from vane to stator. It gets more stable performance and longer life effect at higher working pressure and rotating speed. 2. The structural of intra-vane has low noise. And the design for 12 vanes makes flow pulse smaller, noise lower. 3. It is easy to use and convenient to maintain because of the choose for diversified displacement and insertion structural of cartridge kits.
