HJJ500-1100kW – Pump unit structure
The HJJ500-1100kW high pressure pump unit consists of three assemblies: high pressure pump, motor and frame. Each of the 3 assemblies can be serviced independently of the other assemblies. This ensures quick commissioning after maintenance.
The high pressure pump assembly can be supplied with a flanged crane. This integrated crane saves time when removing the pump head. These time and cost savings, together with the outstanding efficiency, ensure an ROI of <18 months.
The HJJ500-1100kW positive displacement pump was designed to be a long-term runner. You can see this in every component of the pump.
Hermetik has been setting the standards in the high pressure pump sector for 40 years.

High-pressure pumps in the steel industry
The high-pressure water from the HERMETIK positive displacemnt pumps can be used in the steelworks to descale steel products. With a pressure of up to 43500 psi, we effortlessly remove every layer of scale from your steel products.
The high-pressure water is generated in the HERMETIK high-pressure pump. This is pumped to the point of consumption via HERMETIK high-pressure pipes made of stainless steel. A consumption point can, for example, be a HERMETIK descaling system that removes all layers of scale from rolling mill products: both the easily removable secondary scale and the stuck-on primary scale.
HERMETIK offers all components from the high-pressure pump to the pipes to the descaling system. The rotating nozzle heads in the descaling system are a patented technology from HERMETIK. Turnkey pump rooms are also part of our portfolio.
