POSITIVE DISPLACEMENT BLOWERS

Gardner Denver Robuschi Tri-Flow 825

The Gardner Denver Robuschi Tri-Flow 825 blower for combination sewer jetter trucks achieves 19 inches Hg vacuum and delivers 4,311 cfm at 18 inches Hg and weighs less than 1,500 pounds, making it suitable for jetting and excavation work. Paired with the company’s product-tuned silencer, the unit is quiet and uses 70% less space than a traditional silencer, according to the maker. For greater work site efficiency, it provides 6% higher flow and 7.2% more fuel efficiency at 18 inches Hg. 866-428-4890; www.gardnerdenver.com/robuschi.


Howden 827 DVJ

The 827 DVJ dry-vacuum blower from Howden is a heavy-duty unit with integral ductile iron impellers. The casing headplates, gear cover and drive-end are gray iron. Carburized and ground spur timing gears are taper-mounted on the shaft and secured with a locknut, cylindrical roller bearings, splash lubrication on both ends, and easy-to-read sight glasses for maintenance. The blower is capable of handling high inlet temperatures for rough applications. An efficient discharge jet plenum design allows cool atmospheric air to flow into the cylinder, so the blower continues to run under blank-off conditions. It comes in a compact, lightweight package and delivers more than 5,700 cfm in an 8-inch gear diameter frame, as well as 28 inches Hg. 800-557-6687; www.howdenroots.com.


National Vacuum Equipment Challenger 1600

The Challenger 1600 high-vacuum blower from National Vacuum Equipment is a 1,600 cfm tri-lobe blower designed for continuous duty at maximum vacuum. It is available in ready-to-install hydraulic or belt-drive packages using corrosion-resistant stainless steel internal components. Available packages include silencers, check valves, moisture trap, cyclone, four-way vacuum/pressure changeover valve and a powder-coated skid. 800-253-5500; www.natvac.com.


VACUUM PUMPS

Elmira Machine Industries / Wallenstein Vacuum 753 Series

The 753 Series vacuum pump from Elmira Machine Industries / Wallenstein Vacuum incorporates extra-wide vanes that allow up to an inch of wear, designed for longer service life. It provides 422 cfm airflow at 1,200 rpm and is precision-machined to provide vacuum levels up to 28 inches Hg. Options include air, liquid or dual cooling systems where air injection is combined with liquid cooling. A pump-flushing port is included on the top valve for convenient maintenance. The quick-access housing end plate allows for easy internal inspection with no bearings to pull. Oil lubrication is via a mechanical piston pump driven by shaft rotation or available with a sight-feed valve oil regulator system using vacuum/pressure to draw oil with no moving parts. 800-801-6663; www.wallenstein.com.


Fruitland RCF870

The RCF870 vacuum pump from Fruitland is available in clockwise and counterclockwise rotation with top- and side-mount, four-way valve locations.

It is a true 4-inch pump with 4-inch pipe connections producing 512 cfm and weighing 575 pounds. It is fan-forced air cooled with an available air injection cooling system for continuous duty at higher vacuum. It includes an integral oil reservoir with low-consumption oil pump, an integral final filter and vane-wear test ports. 800-663-9003; www.fruitlandmanufacturing.com.


Moro USA W Series PM80W

The W Series PM80W liquid-cooled vacuum pump from Moro USA is suitable for a wide variety of applications, including septic, industrial, and oil and gas. It has oiled bearings that don’t require additional maintenance, a sealed positive displacement direct-feed oiling system, Kevlar vanes, an integrated check valve and a changeover valve. A jacketed casing provides liquid cooling, allowing a deeper continuous-duty vacuum. A coolant pump is available for self-contained packages.
