Compatibility
You need to make sure your new excavator hydraulic pump fits your machine. If it does not fit, you could get leaks, control problems, or broken parts. Some common problems are:
Issue Type | Description |
|---|---|
Pressure and flow matching | If the long arm cylinder needs more pressure than the valve can handle, it may break the valve body. |
Control logic compatibility | Some brands use special electro-hydraulic systems. The CAN bus protocol might need reprogramming to stop control problems. |
Pin size tolerance | SANY SY75C uses an 80mm boom pin, but some other long arms are made for 75mm. You may need a custom bushing or change the hole size. |
Tip: Always check the hydraulic connections, control systems, and pin sizes before you buy. If you skip these steps, you might spend more time and money fixing problems later.
You also need to use the right hydraulic fluid for your pump and excavator. If you use the wrong fluid, it can cause overheating, poor lubrication, or seals to fail.
Application
What your excavator does changes which hydraulic pump you need. Different jobs need different pump features. For example, construction, mining, and demolition all need special things from excavator hydraulic pumps.
Application | Requirements |
|---|---|
Construction | Pumps need to last through many cycles, have smooth control, strong seals to keep out dust, and work with many functions. |
Mining | Pumps must be heavy-duty, have high flow and pressure, strong hoses, and parts that can take shock loads. |
Demolition | Pumps need strong cylinders, special circuits for hydraulic breakers, and pressure-relief systems for sudden impacts. |
If you use your excavator for mining, you need a hydraulic pump that can handle lots of fluid and high pressure. For demolition, you need pumps with strong pressure-relief systems to protect against sudden hits. Construction jobs need pumps that control smoothly and have seals to keep out dust.
Note: Always tell your supplier what you use your excavator for. YNF Machinery can help you choose the right new excavator hydraulic pump for your needs.
You need to match the pump’s flow rate, pressure, and fluid type to your excavator’s job. This helps stop breakdowns and keeps your machine working well.
New Excavator Hydraulic Pump Features
When you pick a new excavator hydraulic pump, you should look at its main features and technology. These things change how your excavator works every day. The right pump helps your machine move easily, lift heavy things, and last longer in tough places.
Flow Rate
Flow rate means how much hydraulic fluid the pump moves each minute. You need to match the flow rate to what your excavator needs. If the flow rate is too low, your machine will move slowly. If it is too high, you could hurt the system or waste energy.
Most medium excavators use pumps with flow rates up to 150 gallons per minute.
The hydraulic fluid must move fast enough for all the machine’s jobs.
A good flow rate helps your excavator lift, dig, and swing quickly and smoothly.
You should check your excavator’s manual for the right flow rate. Using the wrong flow rate can make your machine work badly and wear out parts faster. The flow rate also helps the hydraulic fluid cool and oil the pump.
Tip: Always match the pump’s flow rate to your excavator’s size and job. YNF Machinery can help you pick the right new excavator hydraulic pump for your needs.
Pressure
Pressure is another important part of a hydraulic pump. It shows how much force the pump makes with the hydraulic fluid. The right pressure lets your excavator do hard jobs like lifting rocks or digging deep.
Most excavators work at pressures up to 4,500 psi.
The pressure rating changes how much weight your machine can lift and how fast it moves.
Pressure relief valves keep your system safe from too much pressure. If the pressure gets too high, these valves send extra hydraulic fluid back to the tank.
Using the right pressure helps your excavator work safely and well. If the pressure is too low, you cannot lift heavy things. If it is too high, you might break hoses or valves. The pump’s pressure rating must match your excavator’s needs and the hydraulic fluid you use.
Note: Always check the pressure rating before you buy a new excavator hydraulic pump. This helps you stay safe and keeps your machine working well.
Build Quality
Build quality decides how long your hydraulic pump will last. Pumps made with strong materials can do hard jobs and last for years. You should look at what the pump is made of and how it stands up to heat, dust, and rust.
Material Used | Durability Features and Technology | Common Use in Pumps |
|---|---|---|
Cast Iron | Strong, lowers vibration | Pump body |
Aluminum | Light, does not rust | Lighter-duty pumps |
Steel | Tough, does not wear out fast | Main structure |
Hardened/Stainless Steel | Does not rust, lasts long | Inside parts |
Bronze/Polymers | Slippery, does not wear out fast | Bearings, vanes |
Rubber (Nitrile, PTFE, Polyurethane) | Stretches, resists hydraulic fluid | Seals, gaskets |
Ceramics | Handles heat and chemicals | High-wear pumps |
Good pumps can last from 5,000 to 10,000 hours. If you use pumps made from weak materials, they break more and do not last long. Dust, water, and bad hydraulic fluid can also make pumps wear out faster. You need to clean and check your pump often to keep it working well.
Pumps with strong seals keep hydraulic fluid inside and stop leaks.
Good build quality means less time fixing and lower repair costs.
The right materials help your pump fight rust and wear.
Alert: Always ask about the materials and build quality when you buy a new excavator hydraulic pump. YNF Machinery has pumps with strong durability and advanced features and technology.
