High pressure piston pumps / triplex pumps - overview
Tirplex piston pumps, or plunger pumps, are positive displacement pumps.
Pump head with three displacement pistons. The rotary motion is diverted by the crankshaft, working piston and crosshead. Drive unit usually consisting of coupling and gear motor.
Three pistons, each running at an offset of 120°, displace the medium in the cylinder to the back pressure generated by the downstream system. Intake and exhaust valves on each cylinder control the flow of medium. The necessary power is transferred from the engine, usually translated by a belt drive or gearbox, to the crankshaft, which converts the rotary motion into a linear piston motion.
Pressure: up to 1500 bar
Flow rate: 0.5 to 300 m^3/h
Viscosity: up to 1 - 200 mPas
Temperature: - 196 to + 300 °C
Power: up to 1600 kW
Solids content: depending on medium
Solids size: media-dependent
Suction height: requires inlet pressure
Heating: electrical, thermal oil, steam, water
High-pressure piston pumps are suitable for pumping clean, low-viscosity media.
They are used as process pumps in process engineering (chemistry), as well as in petrochemistry in the onshore and offshore sector (e.g. for gas drying). The metal industry also uses this pump technology as a descaling pump or for cooling.
Further applications can be found in the CO2 sector for the food industry, but also for carbon capture.
