There are many features to consider before you buy a hydraulic pump. Before you make your final decision, take a moment to consider the way you intend to use the pump, what you need and what you want. Here are seven things to consider before you buy a hydraulic pump, and how you can use them to help you find the perfect fit. And remember that there is a hydraulic ram for every job.
Viscosity: The viscosity of the fluid inside the pump determines how powerful the pump is. Most pumps have a maximum kinematic viscosity rating. If the liquid has a low viscosity, the pump’s efficiency is limited. If the fluid is too thick, it will cause wear and mechanical issues. The higher the viscosity, the greater the power capacity and the lower the price.
Operating Speed: Another important factor is operating speed. Whether the pump is rated for high or low speeds depends on the operating conditions. The higher the operating speed, the more expensive the pump is. The higher the NPSH, the more expensive the pump will be. Also, the greater the pressure is, the faster it will move. You should know the maximum speed before you buy a hydraulic pump.
Viscosity: The fluid used in your hydraulic system should match the pump’s specifications. Most hydraulic systems use normal hydraulic fluid (mineral oil), which has smart lubrication properties and a higher boiling point. The flow rate is usually indicated in gallons per minute, so you can get an idea of how much fluid will flow through the pump. Having too high or too low viscosity will reduce the efficiency of the pump.
Viscosity: Fluid viscosity is a key feature to consider when buying a hydraulic pump. The fluid’s viscosity will determine the amount of fluid that the pump can handle. For example, a low-viscosity fluid will slow the pump down and increase wear. A high-viscosity liquid will increase friction and may even damage the pump’s gears.
The flow rate: The flow rate of a hydraulic pump is dependent on the type of fluid used. If it’s operating in a high-pressure environment, the pump’s speed must be high enough to meet the requirements of the fluid. It’s also important to consider the media type. Depending on the media, the pump must have the right flow rate for the specific medium. Likewise, the media type must match the specific needs of the user.
Torque: The torque and rotational speed of a hydraulic pump are two critical components of power. If you have a high-pressure machine, the torque will help you get the right amount of pressure. If it’s a low-pressure machine, consider the flow rate. The NPSH should be at least 0.5 meters higher than the NPSHr. The higher the NPSHa, the better.
