1.0 INTRODUCTION
This manual contains instructions for the installation, operation, and maintenance of the
Energy Recovery, Inc.
™
(ERI
™
) PX Booster Pumps for energy recovery in Sea Water Reverse
Osmosis (SWRO) systems in conjunction with ERI’s Pressure Exchanger
™
(PX
™
) technology.
The PX Booster Pump boosts the pressure in the high pressure portion of an SWRO system to
make up the small pressure losses that occur through the SWRO membranes, the PX units and
the associated piping. The PX Booster Pump is designed to withstand a high inlet pressure in a
corrosive seawater environment.
Please read this manual thoroughly before installation or operation and keep it for future
reference. The instructions in this manual are intended for personnel with general training and
experience in the operation and maintenance of fluid handling systems. PX and PX Booster
Pump maintenance personnel are strongly encouraged to attend Factory Training courses

2.0 MATERIALS OF CONSTRUCTION AND QUALITY
ERI’s commitment to quality starts with the fabrication and procurement of top quality
materials made to extremely tight clearances. Every part is checked to ensure it meets all
dimensional specifications during and after each stage of the manufacturing process. All wetted
metal components in PX Booster Pumps are AL6XN
®
or equivalent stainless steel. Impellers
and diffusers are fiber reinforced polymer. The mechanical seal has carbide contact/sealing
faces. Seals are ethylene propylene (EPDM).
Assembled PX Booster Pump units are subjected to extensive testing in our wet test facility.
Each PX Booster Pump is tested for efficiency, operating pressures, and flow rates. Each unit
is tracked with a serial number and the testing records are maintained.
3.0 SAFETY, ARRIVAL AND INSPECTION
The PX Booster Pump has been designed to provide safe and reliable service. However, it is
