Efficient way to move water

Highly efficient and able to handle abrasive liquids and turbid sandy waters, Atlas Copco’s newest portable pumps are at work keeping job sites dry and projects on schedule all over the world. Efficiency and the ability to respond to a broad range of power requirements are prime reasons Atlas Copco chose Perkins® 904J-E36TA engines to power their PAS 200 HF and PAC F88 vacuum prime centrifugal pumps.

“We have used this engine for a specific reason,” said product marketing manager Andreas Neufeld. “A pump core consumes a certain amount of power and requires torque at specific speeds. So, the Perkins 3.6 litre engine, with its specific configuration, was matching perfectly our demand on the pump side.”

In the power range required by the PAS 200 HF and PAC F88 pumps the engine meets U.S. Tier 4 Final and EU Stage V emission standards using a Diesel Exhaust Fluid (DEF) system instead of a Diesel Particulate Filter (DPF) in combination with the catalyst.

“That’s important,” Andreas noted, “because we run these pumps in various speeds, so there is a different engine load demand based on the operating duty point. How much water do we have to pump? How far and what elevation do we have to overcome. All these parameters have an impact on the engine load performance.”

The compact, power dense, 3.6 litre Perkins 904J-E36TA also helped Atlas Copco reduce the height of their new pumps making it easier for operators to manage pipes and connections. The low profile also makes the pumps easier to tow and even increases performance because they gain an extra bit of suction lift by being closer to the ground.
