Considered one of Americas most popular sewage ejectors, this robust family of pumps is known for reliability, durability and performance. These pumps are industry-proven, built of cast iron with stainless steel hardware. Comes with an integral, 2-pole, snap-action float switch. The heat-dissipating cast iron body with powder coated epoxy finish provides maximum pumping performance under the most extreme conditions.
