Current pump stations simply don't offer the efficient performance we need to preserve the environment. Global Green Lifts' unique three-pump lift stations outperforms traditional two-pump stations.

For two-pump lift stations, pump horsepower must be large enough to handle the maximum wastewater inflow. This can result in low-efficiency pump operation and higher energy demand per start. If the primary pump fails, the backup pump must be of the same horsepower capacity to move the wastewater. Water Drop - Three-Pump Lift Stations Two high-horsepower pumps often experience periods of short cycling when the backup pump assists the primary pump due to the combined high gallons per minute outflow rate. Meanwhile, the primary motor turns on and off continuously, resulting in:
In three-pump lift stations, pump horsepower is based on the pump rated efficiency curve and impellers are trimmed as needed. This results in high efficiency pump operation and lower energy demand per start. The primary, backup, and standby pumps each have the same lowest possible horsepower, with the backup and standby pumps assisting the primary pump. Short cycling is thereby eliminated through the use of our patented control panel and the operating sequence of the low horsepower pumps. The primary pump runs continuously, while the backup pump turns on occasionally and the standby pump rarely runs. This setup means:
