About Sump, Water-Removal, Condensate, and Submersible Pumps

About Drum Pumps

These pumps are C-UL listed for Class I, Division 2, Group D for use in environments with flammable gases. Operating on a 12-volt battery, use them to transfer and drain fuel such as gasoline, diesel fuel, and kerosene. They have an automatic shut-off nozzle so they turn off when the tank is full. Lock the nozzle with a padlock (not included).

Always bond and ground your application for static control. For more information about bonding and grounding, see Sections 1910.106 and 1910.107 of the Federal OSHA Code or see bonding and grounding equipment.

High-Flow Sump Pumps for Sewage Water with Replaceable Float Switch

These pumps provide about 25% more flow than standard float-switch activated pumps for sewage water. The float switch has a separate cord that can unplug, so you can replace the switch without replacing the whole pump. Pumps are equipped with a large intake and rugged impeller to transfer raw sewage water with solids up to 2" in diameter. They have a cast iron housing that stands up to demanding environments. Pumps can run dry.

Sump Pumps for Water with Small Solids with Replaceable Float Switch

The float switch has a separate cord that can unplug, so you can replace the switch without replacing the whole pump. Also known as effluent pumps, these accommodate solids up to 3/4" in diameter. They’re often used with liquid waste that has passed through a septic tank, so most solids are removed. All have an epoxy-coated cast iron housing that stands up to demanding environments. Submerge while in use and do not run dry.

Water Removal Pumps with Hose

Use this pump to remove water with small solids up to 1/4" in diameter. It activates when plugged in; add a plug-in switch to control when the pump activates. Install in water that's at least 2" deep. Pump includes a 25-ft. hose with cam-and-groove fittings for quick, secure connections and a storage crate with built-in filtration to protect the pump from debris.

Note: Pump must be filled with liquid before use. It needs a constant flow of liquid and cannot run dry.
