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.

Road Sweeping

We supply a wide arrange of 12 volt and hydraulic powered diaphragm pumps for the street sweeping industry for dust suppression and flushing debris from sewer drains

Turf Spraying

Comet diaphragm pumps are ideal for handling abrasive wettable powders and corrosive chemicals used for spraying golf courses, lawns and sports fields. Click here (link to master-mfg skid sprayers) to see some turf, golf and lawn sprayers that use Comet diaphragm pumps.

Carpet Cleaning

The Comet P33T diaphragm pump out system is the gold standard in commercial truckmount 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.

Agricultural Spraying

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.

Horizontal Drilling

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.
