Bypass pumping involves maneuvering liquid (sewage, trash, water, etc.) around a damaged pipe without interrupting the flow of liquid while the repairs are underway. This process is critical for many rehab projects, as it allows for a pipe to be repaired or replaced without spillage on public or private property. Bypass pumping uses a PAS HF, which is a centrifugal pump that can handle liquids containing solids of up to 1.8". Because of this, the PAS HF pump is well suited for bypassing in construction, industrial, and municipal applications.
Bypass is common in these sectors:
Solids can build up at wastewater treatment plants or places a digestor is used over time as they settle out with solids. The build-up of solids, sludge, and stringy material in digester tanks can negatively impact the operation of digesters. This requires the right pump, usually with an open impeller to get a clean, easily flowing body of water.
Areas for Digestor cleanouts :
Site dewatering is the process of taking and removing water from construction sites, quarries, mine shafts, or any other area. Extracting water from these areas is crucial to maintain a safe working environment as well as reduce any costly delays.
Due to the PAS' ability to handle pumping high volumes, this pump is able to displace not only water, but sewage, industrial waste, chemicals, and even some solid products.
