High performance and longevity ratings, low operating costs and continuous vacuum are all highlights of the new PM3000 Storm vacuum pump, unveiled by Moro USA at the 2014 Pumper & Cleaner Environmental Expo International.

The PM3000 Storm is an addition to the company’s Storm series of liquid-cooled models capable of pumping nonvolatile liquids and sludge from long distances, providing a solution for heavy-duty industrial applications with a suggested tank capacity of 3,000 to 9,000 gallons. It is capable of 29 psi and features a 4-inch flange connection.

“It’s rated at 1,000 cfm free air, and was designed to appeal to vacuum truck operators who work in the industrial sector, including oil and gas utilities, municipal utilities and hydroexcavation,” says Dave Flagg, company president. “It is also a pump that will appeal to municipalities that operate trucks continuously. It’s not your typical truck-mounted vacuum pump.”

Like all of Moro’s liquid-cooled vacuum pumps, the PM3000 Storm includes an integrated check valve, change-over valve, automatic oiling system, industrial-duty bearings, Viton seals and state-of-the-art high-flow-rate asbestos-free spark-proof vanes. It incorporates a cantered rotor that promotes less air slippage with six Kevlar, heat-resistant vanes that improve performance and recovery time.

“This isn’t the largest vacuum pump model we’ve made,” Flagg says, noting the company’s other vacuum pump models are designed for tanks ranging from 1,000 to 9,000 gallons. “This design provides a higher cfm rating at 24 Hg continuous [28 Hg maximum], which is really the top end when you need deep vacuum and high flow, such as when hydroexcavating.”

A cantered rotor and Kevlar vanes allow the pump to generate 29 psi. In addition, the efficient design means the pump doesn’t need to spin as fast (1,200 rpm), which also increases longevity and reduces heat, noise and oil consumption, Flagg says. “This unit is built to run 24/7 and last.”

The self-contained closed-loop oiling system injects oil into the pump’s housing, lubricating the vanes and industrial-grade bearings. The integrated four-way valve allows it to work under both vacuum and pressure, boosting longevity in applications where the pump works at high pressure for long periods, Flagg says. In addition, its onboard liquid cooling system incorporates a forced circulation external water pump and cooling circuit “burp” points that are manually operated to remove all air pockets from the cooling circuit. The new systems were in the research, development and testing phase for roughly five years before being introduced to the marketplace, according to Flagg.

“The response has been terrific,” says Flagg. “We took orders for several units from our dealers right at the Expo.”

As for the company’s plans for the 2015 Water & Wastewater Equipment, Treatment & Transport Show (WWETT), the new name for the Pumper and Cleaner Expo, Flagg says Moro USA is working with all industry segments promoting its products.

“Our goal is always to have something new ready to bring to the Expo, and I know our research and development team has some projects that we’re very excited about,” he says. “We’re already looking forward to next year.” 800/383-6304;
