PAS HF - Vacuum prime centrifugal pumps

The pump system consists of a centrifugal pump and a separator, which enables air to be separated from the liquid and be sucked by a vacuum pump - making automatic priming possible. Even with suction heights of several feet the machine rapidly evacuates the air from the suction pipe and starts to pump. Additionally, thanks to the semi-open impeller, the PAS HF range is also suitable for pumping liquids with solids in suspension.

The PAS 100 HF T4F YD for high-pressure applications, have been designed to reduce downtime and prolong lifespan, saving operational costs. 

The PAS 100 HF Atlas Copco pump is designed to withstand toughest applications and delivers best in class pumping efficiency. One of the most common area of utilization is the Construction dewatering and municipal market segment where reliability, serviceability and versatility is the key to provide a customized solution. Other suitable applications can be found within the Industry, Mining or Oil & Gas segment. Atlas Copco pumps are packed with features that not only meet, but exceed the needs of our customers.

Applications & Use Cases

Sewer Bypass / Lift Station Bypass

PAS 100 sewer bypass

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:

  • Municipalities
  • Civil Construction
  • Industry

Digestor Cleanouts

PAS 100 draining sludge from treatment facility

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 :

  • Aeration basin
  • Lift station
  • Digester Cleaning
  • Sludge Removal

Dewatering

Water transfer in quarry and mine

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.

Areas for site dewatering :

  • Quarries
  • Construction sites
  • Mine shafts
  • Municipalities
