V Series double pumps


      Shape and introduction These series of composition vane pumps in high performance are developed for industrial application. They can be applied properly in the hydraulic system of plastic injection machinery, rubber machinery, casting machiner, machine tool industry, etc.

The main features are:
1. The designing structure of composition vanes reduces its impact on the stator, so the pumps will have further stability and longer lifetime while working with high pressure and high speed.
2. The designing structure of composition vanes itself reduces the noise. The design of 12 vanes makes smaller flow pulsation and lower noise.
3. Multi-displacement option and the cartridge structure of pump core make flexible application and casy maintcnance.

Operation and Maintenance

♦Hydraulic oil

It is recommended to adopt anti-wear hydraulie fluids with viscosity of 32est-68est under the temperature of 40℃, or automobile crankcase oil with alphabetic marks of SC, SD, SE or SF. The recommended viscosity under rated rotation speed and rated pressure should range from 13est to 54est with the temperature range of49℃ to 65℃.

♦Cold start

In the case of adopting SAE 10W type hydraulic oil with viscosity between 860cst and 54est, the operating rotation speed and pressure shall be limited within 50% of rated rotation speed and rated pressure respectively, until the system warms up. Particular attention should be paid to make sure that the whole system including the cylinder and motor on the far away side shall be all warmed up, when the pump starts up with the hydraulic oil viscosity exceeding 860cst.

♦High temperature operation

While working under high temperature, the viscosity shall not be less than 13est, and the temperature shall not exceed 99℃. Otherwise, the service lifetime of pump core components and sealing parts will be reduced.

♦Noise data

The average conditions for noise value testing of series of pumps:

1.Test with rotation speed of 1500r/min in mute laboratory.
2.Anti-wear hydraulic oil with the viscosity of 30cst.
3.The testing temperature of hydraulic oil ranges from 45℃ to 50℃.
4.The distance between the noise sampling site and the back side of pump shall be one meter away.
