The hydroexcavation industry relies on robust, efficient water pumps to withstand challenging operational conditions while delivering consistent performance. Essential for ensuring precise excavation without damaging underground utilities, these pumps play a pivotal role in the overall efficiency and success of hydroexcavation tasks. The following water pumps have been crafted for these exact purposes, boasting features like high-pressure capabilities, corrosion resistance, compact design and temperature resilience. Here's a closer look at three water pumps that are making a mark in the hydroexcavation industry.
Cat Pumps Models 2560 and 2565
Cat Pumps Models 2560 (16 gpm at 3,000 psi) and 2565 (20 gpm at 2,500 psi) hydroexcavating pumps are constructed for continuous-duty applications. BH versions have a machined-bearing cover to mate with Cat Pumps’ 76SAEC.25FR hydraulic bell housing, allowing the 2560BH and 2565BH to be directly driven by an SAE C hydraulic motor. The compact direct drive allows for a space-saving footprint, and is simple to install and maintain, according to the maker. 763-780-5440; www.catpumps.com
Comet Pumps ET 55 Series
From small trailers to large truck-mounted units, Comet Pumps’ ET 55 Series pump was designed for hydroexcavating and industrial jet/vac services in mind. Its high-performance features, compact design, and symmetrical crankcase allows for easy right to left shaft conversion — making installation simple and easy to accomplish. It contains high-reliability high-pressure seals with low-pressure lubrication and recirculation chambers proven to withstand corrosion. It can withstand extreme temperatures with its stainless-steel suction valves and guiding pistons, nickel-plated brass and an aluminum alloy pump body. It can operate at 1,450 RPMs and 3,626 psi. Its shaft support system and tapered roller bearings will enable this pump to run for extended periods of time. 800-864-1649; www.cometpump.com
Dynablast Pratissoli HY-PACK KTX24A
Pratissoli HY-PACK KTX24A direct-drive water pump packages, distributed by Dynablast, are compact and lightweight. They offer 13.5 gpm at 3,625 psi at 1,450 rpm, or are available in the KTX28A that offers 18.4 gpm at 2,900 psi at 1,450 rpm. They have a direct drive T13 female spline shaft input and SAE B 2/4 bolt flange, and come mounted from the factory with an IPH FOX Interpump 47 or 64CC hydraulic motor. Their 420 stainless steel nickel coated manifolds make them harder for cavitation protection. They come with a Kevlar/graphite rope run dry seal for longer life and can handle higher temperatures. They are self-lubricating so no oiler kit or weekly oiling is required. Internal fins on the aluminum crank case provide cooling to lower oil temperature. Two-bore ceramic plungers have thicker ceramic on the water end to prevent from thermal shock. 905-867-4642; www.dynablast.ca
