Vacuum excavation continues to grow in prevalence and popularity, but huge hydroexcavators and vacuum trucks aren’t always able to get into all the tight spaces where crews need to work. Fortunately several manufacturers are now addressing the need for smaller, yet fully equipped and capable machines. These skid-mounted vacuum excavation units are built for easy installation on both new and used truck chassis and can even be mounted on all-terrain vehicles for more remote work.

To provide pumping power to these compact packages, Comet Industrial Pumps has introduced the ETH Series, a range of triplex pumps with nickel-plated brass head and aluminum body weighing only 88 pounds. The pumps are designed to offer similar performance to the typical high-flow pumps found on large hydroexcavation units, but in an ultracompact size.

“This is a pump series designed to be compatible with any hydroexcavation truck,” says Pete Gustin, product manager for Comet Industrial Pumps. “It saves a lot of space and weight while providing the psi you need. Most trucks are overweight, and this helps mitigate that issue.”

The ETH Series is a solution for urban and industrial pumping and hydroexcavation units, according to Gustin. It offers multiple gearbox positions and a symmetrical crankcase for application flexibility, along with oversized, tapered roller bearings for increased durability. Stainless steel, spherical suction valves provide complete sealing. It comes standard with heavy-duty seals that have low-pressure lubrication and a recirculation chamber. In addition to self-priming, it offers quick access to oil and seals for simple routine maintenance. The unit is also available with a female shaft.

Gustin says that as the company researched ways to increase efficiency and decrease the footprint of its pumps, it found that many customers ran pumps that were too overpowered. “Most contractors don’t use near the 4,000 psi capacity that their pumps offer,” he says. “We’ve been able to shrink down their pump while still providing them the power they need.”

ETH Series pumps are available in models that offer 1,450 to 1,750 rpm, 7.9 to 14.23 gpm, and 35.9 to 39.8 hp. “This pump has been the silver bullet for many of our customers,” Gustin says. “It’s exactly what they’ve been looking for.” 800-708-1894; www.cometpump.com.
