Hydraulic pumps are subcategorized according to type and operating specifications. As to the type, it can be an axial or radial piston, an internal or external gear or a vane. As to operating specifications, it includes continuing and maximum operating pressures as well as operating speed, horsepower and temperature. At times, it may also be maximum fluid flow and viscosity and pump weight. Below are explanations on the types and operating specifications of a hydraulic pump

 

The various operating specifications

 

The continuous operating pressure for hydraulic pumps is described as the maximum amount of pressure that provides proper functioning to the pump. The maximum operating pressure, on the other hand, is also capable of providing the maximum amount of pressure to the outlet but only at an intermittent basis.

 

The different types

 

The axial piston type of hydraulic pump is termed as such because it makes use of the so-called axially-mounted piston. This is a crucial part in pressurizing fluid. The process happens after the mechanical energy is utilized to power up the piston. The piston then passes through the chambers of the pump and becomes responsible in pressurizing the fluid.

 

For the radial piston hydraulic pump, radially-mounted pistons are used. In this type, an alternate motor may also be used to operate multiple pistons. The power source is responsible in making the pistons move and pressurize the fluid.
