Two Stage Regenerative Turbine Pump
Our Two Stage Regenerative Turbine Pump is a specialised solution designed for low NPSHa, low flow, and high head applications. A variation of our Alloy Turbine Pump, this Regenerative Turbine Pump’s unique double-stage construction features a Francis vane centrifugal impeller at the first stage and one/two regenerative turbine impellers to flood the second and/or third stages (three stages with 2 booster impellers available on request). API685 compliant, barrel type, end-suction, top-discharge, and centreline mounted, this pump is particularly suited for handling liquefied gas, condensate hydrocarbons, ammonia, and cryogenic liquids.Â
Typical Industries for our Two Stage Regenerative Turbine Pump:
- Water Treatment
- PharmaceuticalÂ
- Chemical
- Petrochemical
- Refinery
Features & Benefits
- Sealless & Leak-Free Mag Drive Construction
- Close & Long Coupled Configurations
- Double-stage design tailored for low NPSHa, low flow, and high head applications
- Smooth and balanced pumping action through the regenerative principle
- Impeller magnet floats freely, ensuring long life and trouble-free service
- Differs from centrifugal Pumps in that the fluid travels through vanes multiple times, offering higher pressure-building capabilityÂ
- Suitable for clean fluids and systems with close internal clearances
- Double-stage floating impeller design prevents thrust load on motor bearings
- Hydraulic self-centering in the impeller cavity for stability
Benefits of the Regenerative Turbine Principle:
- Fluid is directed to both sides of the impeller, creating a drawing force
- Circulatory flow through the vanes generates fluid velocity
- Multiple cycles of regeneration result in pressure-building capabilityÂ
- Two-sided floating impeller design for stability
