A dynamic pump that contains impellers provided with vanes to generate centrifugal force to achieve the required pressure head.
A dynamic pump that contains impellers provided with vanes to generate centrifugal force to achieve the required pressure head.
A valve that can be used to obstruct the fluid passing inside, and has the ability to reduce the pressure from the inlet port to the outlet port.
A pressure relief valve that has its closing force provided by a spring.
A pressure relief valve that uses a pilot valve to indirectly activate the main valve.
A pressure relief valve that is intended to release excess pressure or admit pressure to prevent a vacuum forming when filling or emptying a pipeline or tank.
A positive displacement pump which contains a displacing element intended to be moved in a reciprocating movement to exert pressure on a fluid, typically moving within a cylindrical space.
A positive displacement pump that consists of a chamber containing gears, cams, screws, vanes, plungers or similar elements actuated by relative rotation of the drive shaft or casing and which has no separate inlet and outlet valves.
A relief valve that is used for pressure compensation purposes by admitting (letting in) a pressure to prevent that vacuum is forming when filling or emptying a system.
