  • Completely Submersible to Offer Significant Benefits

The WAYNE CDU800 is a superior model of a regular sump pump with the difference that it is installed inside of the sump pump pit. This is in stark contrast to the regular sump pump, which sits above the sump pit, allowing for a lid on the top. A submersible sump pump like this one can offer several additional benefits, including increased resistance to overheating, more power, and better overall quality. More and more home users these days are opting for submersible sump pumps due to these benefits.

  • High-quality Construction Materials for More Reliability

The fully submersible pump is manufactured with coated steel and a cast-iron bottom for improved quality. A ceramic mechanical seal is provided to work smoothly in some of the most demanding environments. The top suction design of the pump filters debris and minimizes clogging. The pump’s impeller is crafted out of abrasion-resistant glass-reinforced polycarbonate for more reliability. The fasteners are built with corrosion-resistant stainless steel.

  • Extremely High Water Removal Capacity

This 1/2 HP submersible pump is built to remove varying quantities of water, depending on the height at which it is installed. If installed at the height of 20 feet, it can move 2,040 gallons of water per hour. Starting from this, as you keep decreasing the height of installation, the quantity of water moved will keep on increasing. At the lowest height of 0 feet, the pump can move a staggering 5,100 gallons of water per hour.

  • Designed to Withstand Damage

This pump is meant for use in an 11-inch diameter or larger sump basins. It works at 9 inches on the level and 4 inches off level. The vertical two-pole switch on the pump helps prevent basement flooding, and disconnecting 115-volt conductors prevent damage from lightning.

Unlike other sump pumps, the oil bearings of this pump are permanently lubricated and hence don’t need frequently oiling.
