The first step in selecting a hydraulic pump is to thoroughly understand your system’s requirements. It’s essential to consider both pressure and flow needs, as these two factors greatly influence pump selection.
Identify Maximum Pressure: Determine the maximum pressure your system will require during operation. This includes considering any unexpected pressure spikes that may occur. Sauer Danfoss pumps come with various pressure ratings, so ensure that the selected pump can handle the peak pressure.
Assess Flow Rate: Calculate the flow rate needed for your hydraulic system. This is typically measured in liters per minute (L/min) or gallons per minute (GPM). Evaluate the operation scenarios to establish the flow rate necessary to drive your actuators or motors effectively.
Choosing the Right Pump Type
Sauer Danfoss offers a variety of hydraulic pumps, including gear pumps, piston pumps, and vane pumps, each suited for different applications and requirements.
Gear Pumps: These are robust and reliable for applications requiring moderate flow and pressure. They are suitable for situations where the flow does not need to be variable.
Piston Pumps: Ideal for high-pressure applications, these pumps provide variable displacement which is necessary for systems needing dynamic flow adjustments.
Vane Pumps: These pumps are versatile and can manage a range of pressures and flows, making them suitable for mobile and industrial applications.
