10 HP Osmonics Tonkaflo High Pressure Pump | SS1832B-12400 | 32 Stage | S/N 4781111R-3

10 HP Osmonics Tonkaflo (GE) High-Pressure Pump | SS1832B-12400

The Tonkaflo SS1832B-12400 is an industry-leading multi-stage centrifugal pump, engineered for high-pressure water treatment and process fluid applications. This 10 HP unit features a 32-stage design, capable of providing the significant pressure boost required for Reverse Osmosis (RO) systems, membrane filtration, and industrial wash-down. Constructed with a 316 Stainless Steel shell and high-purity Noryl internals, it ensures a contamination-free flow path and exceptional corrosion resistance.

Manufactured in 1997 (S/N 4781111R-3), this unit is built to the high engineering standards of the GE/Osmonics peak era. It is designed for continuous duty at 3500 RPM, delivering up to 750 PSI of discharge pressure. Its compact, vertical-friendly orientation makes it an ideal fit for modular water purification skids where space and high-pressure performance are critical.

Key Features

• High-Pressure Capability: The 32-stage internal stack provides a massive pressure boost, making it a "Tier 1" choice for RO desalination and boiler feed applications.
• Corrosion-Resistant Design: All wetted metal parts are 316 Stainless Steel, ensuring long-term durability in high-purity water and mildly aggressive chemical services.
• Serviceable Stack: The "B" series design allows for relatively straightforward maintenance of the internal stage stack and mechanical seal compared to larger multi-stage pumps.
• Energy Efficient: Engineered for optimal hydraulic efficiency at 3500 RPM, reducing the electrical load required to maintain high system pressures.
