Submersible pump Tsurumi Avant MQ Series

The Tsurumi Avant MQ series pumps are equipped with high-efficiency IE3 motors, significantly enhancing operational efficiency while reducing energy consumption. This reflects Tsurumi’s commitment to providing sustainable and environmentally friendly solutions.

The Tsurumi Avant MQ series offers a variety of options with five types of impellers (Open Channel, Chopper, Vortex, Grinder, and High Head) and a wide range of technical specifications, including discharge pipe diameters from 50 to 500 mm and motor power from 1.1 to 355 kW. Additionally, the MQ series offers two installation options: the WET version for submersible use or the DRY version for installation inside or outside the tank with a unique closed-loop cooling system. Tsurumi MQ series pumps meet IECEx explosion-proof standards, making them suitable for dry pit environments and other hazardous areas.

Construction of Tsurumi Avant MQ Pumps

Cable System

The cable connection system with a cable gland coupling ensures maximum protection from physical and mechanical impacts. The special threaded ring can be removed to attach a rigid or flexible conduit to the cable gland, securing the cable effectively. Upon request, a special resin coating can be applied to completely prevent water ingress, even in cases of external sheath damage. With this advanced technology, Tsurumi Avant MQ pumps maintain stable and efficient operation in extreme conditions.

Electrical Connection

The electrical connection system simplifies wiring installation and is housed in a sealed compartment with an optional leakage detection sensor. This ensures absolute electrical safety, with the leakage sensor providing early warnings of any potential leaks for timely intervention and maintenance.

Temperature Sensor

A crucial safety feature, the temperature sensor protects the pump from overheating. It detects abnormal temperature increases and provides early warnings to prevent damage. This continuous and precise monitoring ensures that the pump always operates within safe temperature limits.

Corrosion-Resistant Coating

A two-component epoxy coating with a standard thickness of 200 μm provides excellent durability and corrosion resistance. Upon request, the coating thickness can be increased to 400 μm, ensuring superior protection in the most demanding applications.

High-Efficiency IE3 Motor

The Tsurumi Avant MQ series features an IE3 high-efficiency motor, optimizing performance and energy savings.

Bearings

Tsurumi Avant MQ pumps come with lifetime-lubricated bearings, designed to ensure an operational lifespan of up to 100,000 hours.

Leakage Sensor

The leakage sensor provides operators with timely alerts when liquid ingress or leakage is detected, enabling immediate corrective action. This prevents costly damages and ensures safe, efficient operation. For explosion-proof models, this feature is crucial in preventing ignition risks in hazardous environments.

Mechanical Seal

The double mechanical seal system, featuring silicon carbide (SiC) seal faces and an oil chamber, eliminates corrosion, abrasion, and clogging risks, preventing seal-related failures.

Impeller Types

The Tsurumi Avant MQ series includes five different impeller designs, each optimized for specific applications:

• Open Channel Impeller (MQB) – Tsurumi Avant series MQB

• Chopper Impeller (MQC) – Tsurumi Avant series MQC

• Vortex Impeller (MQU) – Tsurumi Avant series MQU

• Grinder Impeller (MQG) – Tsurumi Avant series MQG

• High Head Impeller (MQS) – Tsurumi Avant series MQS
