A pump has a piston which is reciprocatingly moved vertically inside a tubular casing to extract fluid, say, from the bottom of a well. The piston, attached to a motor for driving it, has a horizontally extending base plate with a central opening provided with a plug functioning as a check valve. When a fluid is taken in by the pump, the plug is lifted and the fluid is guided into a reservoir above the base plate. When the pressure inside the reservoir exceeds a specified level, the base plate is compressed downward against an upward biasing force thereon. This opens bleed ducts and allows some of the fluid in the reservoir to flow back down to a chamber below the base plate. Pilot holes are also provided to the piston for allowing small amounts of fluid to escape from the reservoir. This allows the pump to idle at the start-up and hence to start the pump smoothly, as well as to prevent any overpressure conditions.
