Product Description
2CY High‑Pressure Gear Oil Pump | 1‑58 m³/h, 2.5 MPa for Oil Pressurizing, Loading and Unloading
The 2CY high-pressure gear oil pump is a high-pressure external-meshing positive displacement gear pump driven by a pair of high-precision herringbone/spiral heat-treated gears. As the gears rotate, the suction chamber volume increases to draw in liquid, the gear teeth carry the medium to the discharge chamber, and the meshing gears squeeze the medium for high-pressure output. The rated pressure reaches up to 2.5 MPa, making it ideal for oil pressurizing, loading, unloading and lubrication supply.
Key Features
- High-pressure output with rated pressure up to 2.5 MPa for pressurizing, loading and unloading
- Herringbone/spiral gears precision-machined and heat-treated for smooth, low-noise running
- Floating bushings automatically compensate clearance for low internal leakage under high pressure
- One machine handles medium conveying, suction, pressurizing, loading/unloading and system lubrication
- Compact structure, easy maintenance; cast iron and stainless steel material options
- Medium must be free of solid particles and fibers; not suitable for non-lubricating, highly volatile or low flash point media

Frequently Asked Questions
Q: Can 2CY transport gasoline or benzene (low flash point, high volatility media)?
A: The standard configuration cannot. For low flash point media, a copper gear explosion-proof configuration plus an explosion-proof motor must be used.
Q: How to choose between KCB and 2CY?
A: If the output pressure exceeds 1.6 MPa, choose the 2CY high-pressure gear pump. For medium/low pressure general oil transfer, prefer the KCB with built-in safety valve.
Q: Why does the flow decrease after a period of use?
A: Gear and bushing wear increases the end-face clearance, causing internal backflow under high pressure. Install a filter on the inlet to reduce impurities entering the pump chamber.
Q: Can the 2CY pump run in reverse?
A: The standard model has fixed inlet/outlet and does not support reverse running; reverse running requires a custom structure.
Q: Can it be used above 80°C?
A: The standard model is limited to 80°C; high-temperature conditions require high-temperature resistant materials and seals.
