Tsurumi America launches line of explosion-proof pumps for wastewater applications
Tsurumi America has launched the AVANT Series, a line of submersible, explosion-proof pumps created to increase performance and cost savings on a wide range of wastewater applications.
Released earlier this year in Asia, the new AVANT Series has now made its debut in North America, expanding Tsurumi's product offerings while meeting the demands of larger projects that require particular specifications.
The new AVANT Series was certified in accordance with FM Global explosion-proof specifications to ensure products conform to the highest standards of safety. The pumps feature a modern design and IE3 premium efficiency motors that deliver high performances and withstand continuous duty cycles. They have an exclusive closed-circuit cooling system, utilizing a water-glycol mixture, which prevents contamination of the system while cooling the motor. Additionally, customers will be able to 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.
The AVANT pump 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 AVANT pumps, the mechanical seals are installed in an oil chamber separated from the cooling system and can be changed without draining the system.
"If the primary seal on a conventional pump cooling system fails, it can get completely contaminated, which will damage the pump," Wieczorek explained. "The new cooling system on the AVANT Series offers an extra layer of protection to the pump, as the glycol mix runs in a different path. That makes the cooling system more reliable and efficient."
