The utility model discloses a full water-lubrication superhigh pressure plunger-type water pump essentially comprising a chamber, a rotary main shaft, and a plunger port unit, wherein the plunger port unit contains a port valve component and a plunger sliding shoe component, the chamber being divided into a pressure chamber and a lubricating chamber which are mutually independent by the plunger sliding shoe component. The plunger sliding shoe component is driven by the rotary main shaft to perform reciprocating movement, which enables the port valve component to carry out water charging and water discharging through a water pump inlet and a water pump outlet and simultaneously to introduce water to the lubricating chamber through the water pump inlet so as to provide fluid lubrication to a rotary unit and thus achieve full water lubrication. The port valve component adopts integration design, which enables a quick exchanging of component in maintenance and a reduction in maintenance time. The plunger substant
