Used Pieralisi Hercules 470/3 Decanter Centrifuge – 4000 RPM, SS, WWT Application, Complete System

🏭 Manufacturer

Pieralisi Group
Pieralisi is globally recognized for its high-efficiency centrifuge systems, commonly used in wastewater treatment (WWT), food processing, oil separation, and chemical applications.

📝 Description

This used Pieralisi Hercules 470/3 Decanter Centrifuge is a high-speed, industrial-grade separation system designed for solid-liquid separation, specifically previously used in a wastewater treatment (WWT) application. The unit features stainless steel product contact surfaces and operates at a maximum bowl speed of 4000 RPM, enabling efficient sludge thickening and dewatering.

The system includes single-row cake discharge ports, a heavy-duty conveyor, casing, and gearbox. It is powered by a 37 kW main motor (380V, 3-phase, 50 Hz) and a 15 kW Roto-variator motor for torque variation and operational control.

Mounted on 4 sturdy legs, this unit comes complete with:

• Control panel

• Pumps and piping

• Valves and sensors

• All necessary infrastructure for operation

This makes it a turnkey solution for any sludge or industrial liquid/solid separation process.
