Zenit ZMD Series Submersible Mixer for Mixing Liquids in Water Treatment and Purification Plants

The Zenit ZMD Series submersible mixers are engineered for high-efficiency liquid mixing in civil and industrial water treatment and purification systems. Designed with modular construction, these mixers deliver powerful, energy-efficient operation through the same IE3 premium motors used in the renowned Zenit UNIQA pump series. They are ideal for homogenising, preventing sediment build-up, and supporting aeration processes in both new installations and system retrofits.

ZMD mixers feature direct drive motors ranging from 0.75 to 4.0kW and propeller diameters between 200–400mm. With innovative engineering and high-grade materials, they offer reliable performance, exceptional durability, and reduced operating costs.

FEATURES

• Premium IE3 Cold-Running Motor: High efficiency, continuous-duty motor with insulation class H (180°C) for reduced energy consumption and extended service life.
• High-Performance Propeller: Cast AISI 316 stainless steel propeller with thick blades optimised for strong hydraulic efficiency, anti-fouling design, and rugged operation.
• Mechanical Seal System: Dual silicon carbide mechanical seals housed in a large inspectable oil chamber for leak prevention and extended seal life.
• Smart Monitoring Protection: Equipped with thermal protection and an internal leakage sensor to guard against overheating or water ingress.
• Robust Build Quality: Cast iron body, AISI 431 stainless steel shaft, bi-component epoxy coating (200 µm), and A2-70 stainless steel fasteners ensure maximum resistance to corrosion and mechanical stress.
• Flexible Installation Options: Modular design compatible with a wide range of accessories allows optimal placement in tanks—whether permanent or mobile, bottom-anchored or suspended.
• Whisper-Quiet Operation: Acoustic pressure limited to 70 dB for operator comfort.
