HYSEP Solid Bowl Decanter Centrifuge, Model MD44

🏢 Manufacturer Information

• Manufacturer: HYSEP

• Model: MD44

• Serial Number: 113793

• Design Purpose: Originally for chemical processing

• Previous Application: Dewatering biological active sludge in a municipal sewage plant (Denmark)

📄 Product Description

This used HYSEP MD44 solid bowl decanter centrifuge is a high-performance separation unit featuring a bowl and rotating parts manufactured from 1.4462 duplex stainless steel with molybdenum, providing excellent resistance to pitting and intergranular corrosion.

Although designed for chemical applications, this centrifuge was only used for biological sludge dewatering in a municipal wastewater treatment plant. It includes an 18.5 kW main motor and an automatic Rotodiff/Viscotherm hydraulic back drive system powered by a 15 kW motor, delivering precise torque and rotational control. The bowl is rated for a maximum speed of 3,300 RPM at a density of 1,200 kg/m³, and the unit can operate with feed material up to 80°C.
