Selecting the appropriate size hydraulic pump for a dump trailer depends on several factors, including the size of the trailer, the weight capacity of the trailer, and the type of hydraulic system you plan to use.
As a general rule, a dump trailer requires a hydraulic pump that can produce enough pressure to lift the weight of the trailer’s load, as well as enough flow to move the hydraulic cylinder at a reasonable speed.
To determine the size of hydraulic pump you need, you will need to calculate the total weight of the load you plan to haul and then select a pump with a pressure rating and flow rate that can handle that weight.
As an example, a 10,000-pound dump trailer would typically require a hydraulic pump with a pressure rating of at least 3,000 PSI and a flow rate of at least 4 gallons per minute (GPM).
It is important to note that selecting the appropriate size hydraulic pump for your dump trailer is a critical factor in ensuring the safe and efficient operation of the trailer. If you are not familiar with hydraulic systems or pump selection, it is recommended that you seek assistance from a qualified technician or mechanic.
