Marine 2CY Series Gear Pump
1. Application
It applies to delivering non – corrosive lubricating – oil or equivalent liquid without solid particles and fibers at temperature below 300°C and with the viscosity of 5×10⁻⁶～1.5×10⁻³ m²/s (5 – 1500cSt). It applies to hydraulic systems as well. Reducing the speed, the pump can deliver the liquid that the viscosity can be up to 5×10⁶ cSt.
2. Application Scope
It can give perfect performance as transfer pump or booster pump in oil delivery systems, and as fuel pump for delivery, pressurization and injection in fuel supply systems. It can also be applied as hydraulic pump supplying hydraulic power in hydraulic systems and in all industry fields as lubricating pump.
3. Structure Features
2CY series gear pumps are mainly composed of gears, axles, pump body, pump cover, bearing sleeves and axle – end seals, etc. (Special requirements: magnetic force drive and zero – leakage structure can be selected). The nitriding – treated gears have the advantage of higher hardness and wear property, and they rotate with the axles inside the replaceable bearing sleeves. All of the pump’s parts can be lubricated by delivered medium when working.
Four bearing sleeves are installed suspended in the pump body and can be automatically adjusted with facing gaps clearance complying with pressure change, therefore, it results in stable pump pressure, little discharge, flow pulsation and higher volume efficiency. The direction of rotation is clockwise viewed from the coupling end.
