Comet diaphragm pumps are synonymous with quality and innovation. Recognized all over the world, Comet diaphragm pumps are ideal for high pressure airblast and boom spray applications in orchards, vineyards, nurseries, and green houses.
Aluminum and Steel Mills
Hardened bauxite dust on mills, filters, floors, tanks, sumps and sewers; water scale, coke, ore, and lime in heat exchangers, flues, boilers, open hearths, furnaces, chutes and hoppers; descaling billets and water hydraulics; mill scale, tight rust, and weld slag from vessels, tanks, and pipes.
Paint booths, machinery, gratings, conveyers, dollies, and skids.
Expansion joints, grease, rubber, and hydraulic fluids on airport runways.
Breweries and Distilleries
Yeast, sediments and fermentation residues on vats, pipes, and facilities; cleaning boiler tubes, vats, and pipe lines.
The Comet P33T diaphragm pump out system is the gold standard in commercial truck-mount carpet cleaning. Oversized check valves allow for easy passing of dirt and debris of wastewater. We also offer a patented high pressure plunger pump for the pressure side.
Remove dirt, grease, and product build up on grates, floors, external piping, bins, walls, hopper cars, and handling equipment; cooler hearths and pre-heater columns, bins, hopper cars, floors, rotary kilns, and walls.
Chemicals from boiler tubes, tanks, valves, evaporators, heat exchangers, tube bundles, pipes, vessels, reactors, and facilities.
Construction and Renovation
Asphalt distributors, mixers, tar cookers and pavers; asphalt, dirt, concrete, mortar, tar, grease, mastic, and clay on vehicles, mixer trucks, and machinery; canals, lifts, dams and runways; cleaning of natural stone walling, removal of joint materials, coats, damaged or corroded coatings from floors and walls, roughening of concrete and stone surfaces.
Comet is the preferred pump brand for aircraft and roadway deicing and anti-icing sprayers. Diaphragm pumps can handle ethylene glycol at reasonably warm temperatures to allow spraying in even the coldest weather.
Food and Beverages Processing
Fats, oils, dirt and dough, food residues from vats, ovens, mixers, conveyors and facilities; cleaning of cold storage facilities, slaughter houses, fish and meat butchers, sugar processing plants, bottling plants, food cutting, evaporators, milk tanks, centralized dairy systems, ultra-filtration by reverse osmosis; water jet cutting.
Removal of deposits, metal oxidation, ceramic, and sand core materials from castings, furnaces, and paddles.
Horizontal directional drilling is a process done in oilfield fracking as well as utility installation and repair. Comet pumps are used to lubricate and cool the drill bit. Often times, the water is premixed with bentonite clay to reinforce the hole being drilled to prevent collapse. In this case, diaphragm pumps are the best solution as they easily pass the clay particles while providing adequate flow and pressure.
Concrete cement cutting, reclamation and wet sandblasting of tunnels also using special robots. Concrete surface hydro-ripping for large infrastructure, dams, viaducts, homes and offices. Surface penetration.
Removal of marine growth, barnacles, loose paint, and rust on ship hulls, docks, ballasts, platforms, condensers, floating draydocks, anchor chains, storage tanks and boilers. Underwater cleaning of pipes and drilling platforms, of barnacles and marine growth to “white metal.” Coatings removal prior to repainting. Draining of sludge and sediments from cargo holds, ballast tanks, and double bottoms. Surface penetration.
Airport cleaning, nuclear decontamination, cleaning navy applications, wheel and tracked vehicles, rehabilitation and/or decommissioning of concrete installations, cold cutting of ammunition and armored tanks in decommissioned sites.
Pre-maintenance cleaning of dumpers, drag lines, underground haulage lines and shafts; aids in the recovery of ore; unclog plant machinery due to deposits of coal, rock dust, mud or oils.
Reservoirs and containers, sewers and drain pipes, sanitation equipment and refuse vehicles; insulators, boiler tubes, vehicles and machinery; surface penetration.
Removing paraffin and crude residues from platforms and storage tanks; removal of drilling mud and cement from drill pipes; “cold” cutting.
Petrochemical and Refineries
Algae, carbon, scum, soft polymers, and asbestos, wax, paraffin, grease and crude residues, water scale, calcium sulphate, chlorides, hard polymers, iron oxide, coke, hard carbon, PVC and PVA in heat exchangers, re-boilers, tanks, reactors, pipes, cooling towers and facilities, and cold cutting.
Cleaning of chemicals (liquid and solids) from pipes, kettles, mixers, tubes, heat exchangers, reactors, filters, and evaporators.
Removal of rust and varnish prior to re-coating, dope and oil from pipe threads for inspection, drilling mud and debris in various kinds of pipes (internal); manual or fully automatic test units equipped with plunger pumps for filling and test processes.
Nuclear decontamination of fuel capsules, “U” tube exchangers, flash from pre-heater tubes, hand tools and equipment.
Manual or fully automatic Test Benches up 7000 bar, used for pressure testing of valves, tubings, hoses, fittings, and complete systems.
Pulp and Paper
Cleaning of grease, oil, pitch, dirt, and wood pulp form heat exchangers, tubes, foundries, press sections of paper machines, suction rolls, stock chests and lines, and water jet cutting.
Gypsum, potash, cement, lime in hopper cars. Removing grease, dirt, and deposits from trucks, undercarriages, and tanker cars. Removal of leaf mulch from railway lines.
Latex, SBR, and water scale reactors, storage tanks, heat exchangers, tubing, pipes, and facilities.
We supply a wide array of 12 volt and hydraulic powered diaphragm pumps for the street sweeping industry for dust suppression and flushing debris from sewer drains.
Traffic and Transport
Removal of road markings, cleaning of railway carriages and buses, and renovation of concrete surfaces. Cleaning of grease, vegetation, mud, tar, cement, or asphalt on vehicles and machinery; graffiti, stains, tar, and mastics on concrete bridges and overpasses, removal of expansion joints and paint strips; unblock culverts on bridges and clean up overspill.
Comet diaphragm pumps are ideal for handling abrasive wettable powders and corrosive chemicals used for spraying golf courses, lawns and sports fields.
