Product Focus: Explosion-proof Pumps for Wastewater Applications

Dec. 15, 2020
Tsurumi America's AVANT™ Series offers cost savings and a closed-circuit cooling system that prevents contamination of the system while cooling the motor.

Tsurumi America has launched the AVANT™ Series, a line of submersible, explosion-proof pumps created to deliver excellent performance and increase cost savings on a wide range of wastewater applications.

The new pump line features IE3 premium efficiency motors and an exclusive closed-circuit cooling system, which prevents contamination of the system while cooling the motor. It is well suited for applications that require FM approved, explosion-proof pumps.

The AVANT Series was certified in accordance with FM Global explosion-proof specifications to ensure products conform to the highest standards of safety. These pumps feature a modern design and their IE3 premium efficiency motors deliver high performances and can withstand continuous duty cycles. Additionally, customers can order tailor-made AVANT pumps from the factory, with specific configurations that match the demands of their jobs while boosting results.

“We are very proud to bring the new AVANT Series to North America, as these modern, explosion-proof pumps will deliver efficiency and ensure energy savings on a number of projects in the wastewater industry, such as sewage collection from commercial buildings and municipal systems,” said Glenn Wieczorek, managing director at Tsurumi. “It’s also exciting to give our customers the opportunity to build the exact pump they need: with a specific paint thickness or control panel type, for example, or a trimmed impeller to fit an exact duty point.”

Named MQ, the new line of AVANT pumps has five different types of impellers — Open Channel (MQB), Chopper (MQC), Vortex (MQU), Grinder (MQG) and High Head (MQS). It also offers wide ranges of specifications featuring 2- to 16-inch discharge bore diameters and 4 to 215 HP motor output specifications.

One of the options for this new product line is a new coating material called Molib-tech, which is an alternative to the conventional ceramic coating process and particularly suitable for preventing serious wear due to abrasion or cavitation on impellers, suction flanges and volutes. It applies a layer of high-strength material to the iron to improve the pump’s durability.

The series is offered in wet (submersible) and dry pit versions. In the dry pit versions, the motor is cooled by a system exclusive to Tsurumi that uses a water-glycol mix circulating in a special closed loop circuit. An important advantage of the closed system is that it keeps the cooling mix separate from the wastewater in which the pump is immersed. On the pumps, the mechanical seals are installed in an oil chamber separated from the cooling system and can be changed without draining the system. WT

Tsurumi (America) Inc., a division of Tsurumi Manufacturing, was founded in 1979. Headquartered in Glendale Heights, Illinois, Tsurumi (America) is a provider of leading pumping technology in construction, civil engineering, mining, industrial wastewater, domestic wastewater, sewage treatment, flood control and scenery creation fields.
