Integrated Pump and Energy Recovery Pump (IPER) - 1

Fact Sheet IPER* Ultra Efficient Pump SWRO Integrated Pump and Energy Recovery 1,000 m3/d (264k gpd) permeate Figure 1: IPER Ultra Efficient Pump IPER Benefits IPER is one of the most energy efficient pumps in the world (Figure 1). Applied to desalination reverse osmosis systems, it can reduce energy costs by 50%.1 Robust FRP water cylinders Dual-acting pistons transfer maximum energy One button start up and shut down controls Pre-engineered pumping system combines flow controls, high pressure pumping and energy recovery into one skid 100 KW Nominal Operating Power Ultra efficient hydraulic power source Skid mounted master control enclosure Proven, reliable hydraulic power source that is scalable and adaptable Extremely low cycle rate compared to positive displacement pumps No additional controls, drives, pressure regulators, or flow balancing required Modular design Low inlet pressure requirement to desalination plants operating with no energy recovery. Efficiency claims based on competitors published motor and pump efficiencies.

Integrated Pump and Energy Recovery Pump (IPER) - 2

Uses the hydraulic energy from the high pressure SWRO reject, combined with energy from the HPU, to deliver constant flow and pressure to membranes Employs piston as a barrier so there is no appreciable mixing between raw seawater feed and SWRO reject Raw Seawater Water Feed In Cylinder Feed Out Leverages highly efficient and reliable Hydraulic Power Unit (HPU) technology (Fig 2) Eliminates secondary boost pump required by other energy recovery devices Figure 2: IPER operational flow diagram Operating Parameters Maximum SWRO Permeate Fixed Recovery Maximum Pressure Minimum Inlet Pressure...
