What are pressure pumps?

Pressure pumps are simple devices designed to stabilise the output of air, water or oil. They are used extensively in industrial, commercial and domestic environments to supply fluids or air to an application in a measured amount. Within industrial workspaces, pressure pumps are also used to help calibrate, test and troubleshoot pressure-operated products or equipment. 

Depending on the medium it supplies and its operating method, pressure pumps can be classified into multiple types. For instance, hydraulic pressure pumps are used in systems that involve water, and pneumatic pressure pumps are used in systems where air is involved. Alongside these, pressure pumps can be either automatic or hand-operated. 

Working principle of pressure pumps 

The working principle of a pressure pump varies based on its type and application. However, the basic principle remains more or less the same for the majority of pressure pumps, i.e., they increase and decrease pressure within a system or equipment. Usually, pressure pumps feature a piston, rotary vane or diaphragm to pump air or fluid into the system. As the lump draws in the air or fluid, the pressure increases. On the other hand, using a valve or a pressure switch can decrease the pressure by removing the air or fluid from the system. 

Applications 

Pressure pumps are used extensively across different industries. Their most common applications include: 

• Plumbing installations and repairs 
• Testing HVAC systems
• In water pipes systems to locate leaks
• Pressure transmitters 
• As pressure source
• Pressure controllers
