YCB Series Arc Gear Pump
1. Uses
It is suitable for delivering non-corrosive lubricating oil or equivalent liquid without solid particles and fibres at temperatures below 300°C and with a viscosity of 5×10⁻⁶ ~ 1.5×10⁻³ m²/s (5-1500cSt). It applies to hydraulic systems as well. By reducing the speed, the pump can deliver liquids with a viscosity up to 5×10⁴ cSt.
2. Range of Application
- It can serve as a transfer pump or booster pump in oil delivery systems, a fuel pump for delivery, pressurization, and injection in fuel supply systems.
- It can also be applied as a hydraulic pump supplying hydraulic power in hydraulic systems and in all industrial fields as a lubricating pump.
3. Structural Features
YCB series gear pumps are mainly composed of gears, axles, pump body, pump cover, bearing sleeves, and axle-end seals. The gears adopt double-circular-tooth shape, which reduces wear on the gear surface, ensures stable revolution, low noise, long service life, and high efficiency due to no sliding on the tooth surface during gear falling-in. This design gets rid of traditional design limitations and enters a new decade in designing applications.
The pump is designed with a safety valve for protection against overload. The full return flow pressure is 1.5 times higher than the rated exhaust pressure of the pump and can be adjusted within the allowable exhaust pressure range according to circumstances. Note that the safety valve cannot be applied as a pressure-reducing valve for long-term use. Pressure-reducing valves can be installed separately on the pipeline if needed.
There are two types of axle-end seals: mechanical seal and packing seal, which can be chosen according to the client’s requirements or application circumstances. The direction of rotation is clockwise when viewed from the coupling end.
