5. Key Tips for Selection
When selecting double plunger pumps for cranes, it is necessary to comprehensively consider the crane type, hydraulic power demand, working environment and other factors: 1. Select the appropriate displacement according to the flow demand of the crane hydraulic system, especially matching the power requirements of lifting, luffing and other key mechanisms; 2. Confirm the maximum working pressure of the pump to ensure it matches the pressure level of the crane hydraulic system and has a certain overload capacity; 3. Consider the working environment, select pumps with strong anti-vibration, dust-proof and high and low temperature adaptability; 4. Choose products with good interchangeability and easy maintenance to reduce the later maintenance cost and downtime of the crane.
All the above series and models of double plunger pumps are specially designed for cranes, with reliable performance and wide applicability, which can meet the hydraulic power needs of different types and specifications of cranes.
