Pump Lift Station Systems

During the wastewater treatment process, liquids can be transported from one area to another through a variety of means. Perhaps the easiest way to transfer liquids is through a gravity drain. However, there are occasions when gravity drains will not work or they are not practical. In these instances, pump lift station systems can move the wastewater from one area to another.

Vertical pump lift stations are used when there are no appreciable solids and the wastewater must be pumped from a sump to a higher elevation. These pumps make use of vertical centrifugal pumps mounted on the tank covers to move the wastewater. Wastech’s vertical pump lift stations feature plastic tanks made from polypropylene or polyethylene, one pump in a simplex system or two pumps in a duplex system, a multi-point level switch assembly, and a Wastech IPCP series industrial control panel. Wastech offers these control panels with the vertical pump lift station system as part of the package, whereas many other manufacturers require that these control panels are purchased separately. The control panel enables the pump or pumps to operate in automatic mode based on the level switches or in manual mode.

When the wastewater contains solids, an air-operated pump lift station may be more effective than a vertical pump lift station system. These air-operated systems use an air-driven double diaphragm pump to lift the wastewater rather than vertical centrifugal pumps because these pumps are better able to pump solutions with solids. Solvent pump lift station systems operate in a similar manner as air-operated pump stations, but they are specially designed to handle volatile hydrocarbon solutions. These stations feature level switches and pump solenoid valves that are designed to prevent explosions. The pump, tank, and level switches are made from stainless steel to handle solvents.

Wastech Controls and Engineering can also design and manufacture a custom pump list system that meets your specific needs. The pump and tank capacities can be customized, and the materials from which the system is manufactured can be changed to meet your specifications. For example, the systems can be made from Teflon, polypropylene, PVDF, or stainless steel, depending on your needs and the properties of the wastewater you are transporting.
