Centrifugal diesel driven dewatering pumps

Built better

We believe that innovation should be simple, customer driven and make a real difference for users. The introduction of the pump’s hinged canopy is a great example of this approach. This patented design makes service, cleaning and unclogging a simple procedure. All models are available with the choice of a CAT or Deutz Tier 4 Final engine or a VFD electric motor.

Performance

The PAS open frame pump systems consist of a highly efficient diaphragm pump with a semi-open impeller and a large separator. Air is separated from the liquid and sucked by the vacuum pump, making automatic and efficient priming possible. Units are designed to pump up to 8,500 US GPM. Even with suction heights of multiple feet, the PAS pump rapidly evacuates the air from the suction pipe and starts to pump. The semi-open impeller makes the range suitable for pumping liquids with solids in the suspension and the high efficiency hydraulic end guarantees low fuel consumption.

Options and range

Customer choice and satisfaction is paramount. That is why we offer models with 4, 6, 8 and 12” outlet configurations. The pump comes packaged and customized to your needs. We offer multiple skid configurations and options. The PAS range is constructed to go where the job needs it to go and is built with features that make the pump easy to transport.

Control system

While other pump brands offer a control system, we offer PumpWatch – a unique control system that comes as standard, with the option to upgrade to an even more advanced model depending on your needs. Advanced capabilities include an event management system, allowing the user to define operational conditions to trigger events, warnings, faults, and alarms, which can even be received remotely. PumpWatch supports accessories including transducers, float switches, flow meters and pressure gauges and comes with multiple language settings.

Application

There is nothing limiting these pumps for any application within their defined parameters – which provides a wide choice of options. You can also be assured that the PAS range performance has been tested and verified in the toughest of working conditions.

The PAS range of fully automatic self-priming centrifugal pumps are considered the ideal solution for transporting or raising water with abrasive solids in suspension. They are used across multiple industries including construction and mine site dewatering, floodwater, stream diversions and municipal applications. They can work with water that is clean or dirty as well as handle trash and fibrous materials. They have excellent solids handling capability, thanks to features such as semi-open impellers and abrasion-resistant pump casings.

The PAS range was developed as the result of over 140 years of experience that has been tried and tested all over the world and within a strategy that fits perfectly with pump developments. The primary focus is on providing efficient equipment. We strive to continually develop products that are better for customers and better for the environment. Secondly, the end products should be easy to take to the point of use and therefore there is a major focus on manufacturing pumps that are smaller and lighter, with features that make them easy to move around.
