PAC FLOW SERIES

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 evacuates the air quickly from the suction pipe and starts to pump. Additionally, thanks to the enclosed impeller, the PAC range is also suitable for pumping liquids with solids in suspension with best possible efficiency.

The PAC F1212 VD-S 285HP T4F for high-pressure applications, have been designed to reduce downtime and prolong lifespan, saving operational costs. 

This centrifugal pump can handle liquids containing solids of up to 3.5" in size. This makes it particularly well suited to industrial applications, such as water transfer in the oil and gas sector, quarrying and surface mining, construction, and municipal applications. 

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 enclosed impeller, the PAC range is also suitable for pumping liquids with solids in suspension with best possible efficiency.

Applications & Use Cases

Bypass

Allied 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 PAC H, which is a centrifugal pump that can handle liquids containing solids of up to 3.5". Because of this, the PAC H pump is well suited for bypassing in construction, industrial, and municipal applications.

Bypass is common in these sectors:

  • Municipalities
  • Civil Construction
  • Industry

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 PAC's 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

Emergency Response

Emergency Response

Whether it is a hurricane, flood, natural disaster or sewer line collapse; Atlas Copco PAC F pumps are up to the challenge. The PAC F is a centrifugal pump that can handle liquids containing solids of up to 3.5" in size, which makes it well suited for any emergency.

Emergency Response is common in these sectors:

  • Municipalities
  • Civil Construction
  • Industry
  • Mining
  • Oil & Gas
