Lee Ventus long life disc pump exceeds 17,000 running hours

Micropump manufacturer Lee Ventus (formerly known as TTP Ventus) has announced that durability testing of its LT Series disc pump has surpassed 17,000 hours of operation.

Lee Ventus says that this extended service life means that LT Series pumps can serve ever more-demanding applications, with the pump able to support 2 years of continuous use.

“During testing, pumps are driven in an elevated environmental temperature of 40°C (104°F) and against a restrictive load that limits the amount of airflow (and therefore cooling) through the pump. These conditions are intended to accelerate the wear processes to ensure that we put the pump through its paces,” said Burag Yaglioglu, Reliability and Data Analytics lead at Lee Ventus.

“In this test, the pumps ran at 0.6 W—or about 60% of their rated power—without significant change in their performance for 17,000 hours—as the pump operates 21,000 times per second, this equates to around 1.3 trillion cycles. We’ve been able to deliver this exceptional result through advancements in valve technology.”

Tom Harrison, managing director of Lee Ventus, added: “When we introduced the LT Series with a lifetime of 5,000 hours, we emphasised our commitment to driving further improvements over time. We are delighted to deliver on this ambition and to broaden the range of applications that can take advantage of the technology.”
