The skid- or trailer-mounted SiteMax centrifugal pump from PowerPrime Pumps has a venturi or vacuum priming system that enables it to prime and re-prime in less than 20 seconds and on section lengths of 100 feet or longer.

“We’ve spent over two years designing this product,” says JP Lake, president of PowerPrime Pumps. “It’s the first product from PowerPrime that has been designed 100 percent from the ground up. We had about 20 prototype units in the field for over a year making sure it performed to our expectations.”

The pump has an alloy steel screw-type centrifugal, non-clog impeller with push/pull function for greater suction lifts and less downtime when pumping stringy or incompressible solids.

“It also comes with a rotationally-molded, high-density polyethylene canopy, which makes it very quiet,” he says. “With our largest 74 hp engine it’s under 70 dBA at 23 feet.”

Applications include digester cleaning, pumping down clarifiers or transporting sewage to another part of the plant.

“Guys responsible for the collections side of their system can use it as a bypass pump,” Lake says. “You can even use it as a dewatering pump.”

Available for rent or purchase, the pump comes in four models (1500, 2000, 2500 and 3000), based on the maximum gpm required. All models come with Kubota diesel engines. The 4-inch SiteMax2000 and 8-inch SiteMax3000 are available for rent from Rain for Rent.

“Everything is built to be Final Tier IV compliant,” Lake says. “We’re producing Interim Tier IV compliant engine units and we will be able to transition to Final Tier IV in the summer of 2015.”

Other engine options include natural gas, propane and gasoline (available in mid- to late 2015).

The pumps have a maximum flow of 1,500, 2,000, 2,500 and 3,000 gpm and a maximum head of 130 to 205 feet. Pump sizes are customizable with 4-, 6- and 8-inch models.

The SiteMax is 152 inches long, 79.1 inches wide and 71.2 inches tall. Models 1500, 2000 and 2500 weigh 3,685 pounds. Model 3000 weighs 4,252 pounds. All units have an 88.5-gallon fuel tank for up to 65 hours of continuous runtime.

The pumps handle up to 3-inch solids and feature interchangeable parts to reduce maintenance cost and downtime. “We have one common volute across all the different sizes; it makes it easy to swap things out if you have a problem or just to keep your inventory level down,” Lake says.

Environmental features include a built-in fluid containment basin that can capture 150 percent of onboard liquids, minimizing the risk of leaks or spills. 661/399-9058; www.powerprime.com.
