How to Select a Hydraulic Pump

Before buying a hydraulic pump, consider the following factors. The pressure and torque of a hydraulic pump are critical to determining its performance. The easiest way to determine these parameters is to compare a machine’s existing pump with a new one. If there’s no comparison, look at the power curves for different specifications. These graphs will help you determine the power demands at different flow rates. A higher pressure equals higher brake horsepower.

When selecting a hydraulic pump, it’s important to check the manufacturer’s literature for the different types of pumps. You’ll want to ensure the unit you’re purchasing is rated for the type of operation that you have. In addition to pump capacity, consider the psi of the system. The psi is calculated from the liquid vapour pressure and the inlet pressure of the pump. This number must be higher than the psi required by the specific application.

Ensure that the fluid you’re using is compatible with the pump. This is especially important if your pump will be operating in harsh environments, where the materials will be exposed to high levels of chemical contamination. The material that the hydraulic pump is made of will also have a profound effect on the pump’s life span and operation. When you select the right type of fluid, you can rest assured that the pump will work efficiently in any situation.

The first step in selecting a pump is to evaluate the application requirements. Although your choice of technology has a significant impact on the final selection, you should always start by considering the load and the system losses. A theoretical pressure and flow characteristic can give you an idea of the input horsepower you need.

The viscosity of the fluid used in the hydraulic pump is a crucial consideration when choosing the right type for your application. This is because the fluid has a different viscosity than the liquid that is being pumped. The fluid that has a low viscosity will not work as efficiently as one that is too thick. The viscosity of the fluid can determine its efficiency and life. If you’re not sure what type of fluid you need, you can consult with a manufacturer. A good hydraulic pump should be compatible with the fluid you’re using. If the fluid has a low or high viscosity, it may be necessary to change it.
