Our range of pressure pumps features a variety of types, including hydraulic pressure pumps, pneumatic pressure pumps, automatic and hand-operated pumps alongside an assortment of pressure test pumps. A simple pressure pumps main purpose is to increase and stabilise the output and supply of either water, oil or air to a given application, whether that be within an industrial, domestic or commercial environment. In some instances, especially within industrial industries, a pressure pump can be used to assist in testing, troubleshooting and calibrating pressure operated products.How does a pressure pump work?The way in which a pressure pump works is entirely dependant on the type and application. The main bulk of them run on the same principle of increasing and decreasing pressure within the system. When a pump is connected to a system it is important to check that the valves on the exit and entry point, this is to be done in conjunction with the pressure dial that shows the current pressure. For pressure to increase, a piston, rotary vane or diaphragm principle is used to pump air or oil by the user into the system. The pump then draws air or oil in and pushes it into the system. To decrease pressure, a valve or pressure switch can be opened to decrease the flow of pressure, which in turn allows air or oil to leave the system.Where can a pressure pump be used?Pressure pumps can most commonly be found in applications that involve:Checking plumbing repair work or installationsTesting or locating leaks in water pipes and central heatingCalibration checks on pressure transmitters, switched, indicators and controllersAs a pressure source in test facilities
