Summary
Product identification
This document describes several high-pressure and circulation pumps designed for reverse osmosis (RO) systems:
- AquaBold High-Pressure Pump: A multi-stage centrifugal pump.
- AquaSpire High-Pressure Pump: A single-stage, high-pressure pump.
- HP Series Low Flow Circulation Pumps: Designed for low flow circulation.
- VP Series High Flow Circulation Pumps: Designed for high flow circulation.
AquaBold High-Pressure Pump
The AquaBold™ pump is a flagship multi-stage centrifugal pump, ideal for large-scale reverse osmosis systems. It is designed for use in any PX system and in any Turbocharger system.
Operating limits
- Flows: 100 to 1,300 gallons per minute (23 to 300 m³/hr)
- Pressures: Up to 1,200 psi (83 bar)
- Efficiencies: Exceeding 80%
Mechanical / hydraulic
- Process lubricated bearings
- Longer bearing life and wear cycle
- Less maintenance than typical pumps
- Low life-cycle cost
- Heavy duty cast and machined stainless steel impellers
AquaSpire High-Pressure Pump
The AquaSpire™ is a single-stage, high-pressure pump, ideal for medium- to large-scale seawater and brackish water reverse osmosis systems. It is designed to complement the AT Turbocharger.
Operating limits
- Flows: 250 to 12,000 gallons per minute (57 to 2,725 m³/hr)
- Pressures: Up to 650 psi (45 bar)
- Efficiencies: Approaching 90%
Mechanical / hydraulic
- Process lubricated bearings
- Longer bearing life and wear cycle
- Less maintenance than typical pumps
- Low life-cycle cost
HP Series Low Flow Circulation Pumps
These circulation pumps are designed to be used in conjunction with PX devices in seawater reverse osmosis plants.
Operating limits
- Permeate production rates: Approximately 25 to 250 gpm (135 to 1,350 m³/day)
Mechanical / hydraulic
- Longer bearing life and wear cycle
- Enhanced corrosion resistance
- Less maintenance
- Specifically designed for SWRO/BWRO applications
VP Series High Flow Circulation Pumps
These circulation pumps are designed to be used in combination with PX devices in seawater and brackish reverse osmosis plants, with the purpose of compensating hydraulic losses in the PX circulation loop.
Operating limits
- Flow rates: 640 to 12,000 m³/day
Mechanical / hydraulic
- Compact vertical inline design
- Highest efficiencies
- Long life and low maintenance
- Low energy consumption
- Reliable performance in high operating pressures
- Specifically designed for SWRO/BWRO applications
- Seal flush with start-up vent valve
- ASME 600# flanges for easy installation
- Simple disassembly for easy mechanical seal maintenance
Electrical
- 50/60 Hz TEFC motor, ready for VFD control
