FEDCO - Model HPB -Hydraulic Pressure Boosters

• Absolute simplest stand-alone Energy Recovery Device
• Lowest capital and installation costs and lowest maintenance
• Best Life Cycle Cost (LCC) in SWRO systems up to 5,000 m³/day
• Reduces the capital and operating cost of the High Pressure pump and motor

• CFD (Computational Fluid Dynamics) analysis is used to fine tune the HPB to your needs
• Industry-leading three (3) year limited warranty 
• Super Duplex SS 2507 is standard MOC
• Custom built to your flow and pressure specifications in 3 to 6 weeks

With ten (10) models, there is a perfect fit for your most demanding performance, reliability and project schedule requirements. Standard MOC is Duplex SS 2205, however, Super Duplex SS 2507 is optional. Brine nozzle valve actuators, flanged connections and other options are available. Delivery of the standard line HPBs are built to your flows and pressures specifications in three (3) to (6) weeks in Duplex SS 2205.

1. Variable area in nozzle (needle type for precise control)
2. Nameplate
3. Thrust bearing – patent pending design, allows dry running
4. Brine nozzle and volute
5. Brine (turbine) impeller
6. Rotor shaft
7. Center bearing — lubricated by feed, ZERO brine leakage to feed
8. Feed (pump) impeller
9. End cap
10. Multi-vane diffuser — radial pressure balanced for long wear ring and bearing
11. Mounting foot (varies by model)
12. O-rings — all bearings mounted on o-rings for easy removal
13. Victaulic-type pipe joints (flanged joint optional)
14. Standard Duplex SS 2205 MOC (Super Duplex SS 2507 optional)
15. Can discharge brine at higher pressure for easy brine disposal

Six (6) models cover the largest current and anticipated SWRO trains. Standard MOC is Duplex SS 2205 with Super Duplex SS 2507 optional. Brine nozzle valve actuators, flanged connections and other options available.

1. Brine aux nozzle valve (needle type for precise control)
2. Nameplate
3. Thrust bearing — patent pending design, allows dry running
4. Brine (turbine) impeller
5. Rotor shaft — integral with impellers (hidden in this view)
6. Center bearing — lubricated by feed, ZERO brine leakage to feed
7. Feed (pump) impeller
8. End cap
9. Multi-vane diffuser —radial pressure balanced for long wear ring and bearing life, provides higher efficiency than volutes
10. Baseplate
11. O-rings — all bearings mounted on o-rings for easy removal
12. Victaulic-type pipe joints (flanged joints optional)
13. Standard Duplex SS 2205 MOC (Super Duplex SS 2507 optional)
14. Brine can be discharged at higher pressure for easy brine disposal
15. Integral brine passage for auxiliary turbine nozzle
16. Hand wheel, optional valve actuator, for brine flow regulation
