There are two basic types of HPRT: Impulse (Pelton wheel) and reaction type.

Generally, pumps are a means of fluid transport that convert mechanical energy into hydraulic energy.

Pumps increase fluid pressure and flow. When process conditions call for pressure to be dissipated, a pump running in reverse may be applied as a reaction turbine to capture that otherwise wasted energy (e.g. by throttling in a valve, dissipating the pressure energy into heat).

With many years of experience and expertise in this field, Sulzer is a leader in HPRT reaction technology with hundreds of installation
