PX Pressure Exchanger Down
Genuine ERI Parts, 4-Hour Response

The Energy Recovery PX is the single most critical energy-recovery device in modern SWRO — and the one with the longest standard lead times. When a PX unit fails, your plant either shuts down or burns double the energy. Alisios sources genuine ERI parts through authorized channels and responds in 4 hours.

Why the PX Is a Single Point of Failure

ERI's PX recovers up to 98% of energy from the high-pressure SWRO reject stream. When a PX fails — rotor seizure, bearing wear, seal failure — the plant faces two options: shut down the train, or continue at double the energy cost. Most operators shut down. Standard ERI parts lead times through normal procurement can reach 4–8 weeks.

Frequently Asked Questions

What ERI PX models does Alisios source parts for?

PX Q400, PX Q300 and PX Q260, plus older PX-220 and PX-300 series still in legacy Gulf plants.

Can the plant run without the PX?

Yes but at roughly double the energy cost — the high-pressure pump must supply full pressure to both membranes and reject stream. Most operators shut down the train.

Why are ERI parts so hard to source quickly?

ERI manufactures precision-lapped ceramic rotor components to micron tolerances. There are no aftermarket alternatives. All parts come through the ERI authorized network.

What information is needed?

Company/plant name, PX model, part description, quantity, destination, and whether the plant is currently down.
