Table 6-1 can result in damage to the PX Booster Pump. Energy Recovery, Inc. declares that ERI PX Booster Pump product lines comply with the essential requirements for CE certification. A CE label is located on the booster pump nameplate. -
Page 5: Principle Of Operation
The PX Booster Pump is a horizontal multistage centrifugal pump driven by a Totally Enclosed Fan Cooled (TEFC) motor. 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 Energy Recovery, Inc. ERI Document Number 80020-01-5... - Page 6 In an SWRO system equipped with PX technology, the main pump is sized to equal the SWRO permeate flow plus a small amount of bearing lubrication flow, not the full SWRO feed flow. Energy Recovery, Inc. ERI Document Number 80020-01-5...
-
Page 7: Installation
SWRO system equipped with PX technology, the main pump will provide 41% of the energy, the booster will provide 2% and the PX unit(s) will provide the remaining 57%. Since the PX energy recovery device uses no external power, the total power savings is 57% compared to a system with no energy recovery. - Page 8 This can cause failure of mechanical seal, shaft and motor Never stand and/or sit on pump wet end. CAUTION Never lift or handle pump wet end while transporting it. All lifting should be done around the motor. Energy Recovery, Inc. ERI Document Number 80020-01-5...
