ROTRON ships 100,000th Pump

Product Announcement from Ametek Dynamic Fluid Solutions

KENT, OH—Rotron® brushless DC water circulation pumps have reached an industry milestone with 100,000 units shipped for customer applications in only 10 years. Marketplace demand has been fueled by their capability to deliver up to 60,000 hours of service life and an unprecedented 4.5-year warranty more than double the industry standard. The pumps serve onboard heavy-duty transportation buses, longer-travel transit coaches, and construction and off-highway vehicles.

Among their features, a seal-less design imparts leak-proof protection and the capability to resist typically encountered harsh environmental conditions, including hot-water spray, salt, fog, shock, and vibration. The pump magnetically couples to the brushless DC motor without a wet seal to wear or replace and enables easy motor removal without requiring system draining.

The integrated electronically commutated brushless DC motor offers virtually maintenance-free and long-time operation by eliminating brush maintenance and associated brush motor failure. Rare-earth magnets promote high efficiency and low current draw; "O" ring seals protect against the elements; and heavy-duty motor construction meets demanding transit bus and construction equipment requirements.

These coolant pumps are available in several sizes with 10, 12, 18 or 26 gallon capacities and 12VDC or 24VDC input voltages, depending on model, and can be customized.
