Summary

Flygt Submersible Pumps are designed for heavy-duty dewatering, sludge, and solids-handling applications in water and wastewater, suitable for construction, mining, and municipal use. These pumps are available for both rental and sale.

Product Overview

Flygt pumps feature a compact, heavy-duty design with capabilities for dry running. Key innovations include:

• DuraSpin™ Hydraulic System: Utilizes a unique closed impeller and a suction cover with grooves to sweep abrasive particles away from the impeller neck, enhancing wear resistance and sustaining performance. A single screw allows for easy impeller adjustment to restore performance.
• Spin-Out™: A patented design that protects the outer seal by expelling abrasive particles, extending service life.
• Plug-In™ Seal: A one-piece aluminum housing incorporating two mechanical seals for double protection. The Active Seal™ system prevents liquid from entering the motor cavity, reducing the risk of bearing and stator failure.
• Hard-Iron™ Components: Specially designed impellers (60 HRC) and suction covers are made from Hard-Iron™ for superior wear resistance.
• Efficient Cooling: A shrink-fit motor stator core ensures uniform metal-to-metal contact between the heat-producing motor and its housing, providing exceptional cooling without the need for cooling oil. The Class H motor and aluminum stator housing further improve heat transfer.
• Cable Entry: Features a dependable compression cable seal (Flygt SUBCAB®) that is field-serviceable and does not require epoxy sealers, providing superior mechanical strength and long-term sealing.
• Motor Protection: Includes a sealed-off terminal board, thermal sensors embedded in the stator windings to prevent overheating, and a leakage sensor in an inspection chamber for early warning of fluid build-up.
• Construction: Built with high-tolerance machining, quality O-rings, and robust materials for reliability.

Flygt 2600 Series Dewatering Pumps

The 2600 Series is a line of dewatering pumps known for job site dependability. They are constructed from aluminum and stainless steel, featuring hardened impellers with nitrile rubber adjustable wear parts. These pumps do not require total submersion and can operate under snore conditions.

Other Flygt Pump Series Highlights

• 2600 Series Sludge Pumps (VORTEX Impellers): Designed for pumping water containing moderately abrasive or stringy solid materials, utilizing a vortex impeller to minimize wear and clogging. Constructed from aluminum and stainless steel, resting on a stand.
• BIBO 2800 Series Dewatering Pumps: Offer medium, high, and super-high pressure capabilities. They feature PolyLife™ coated wear parts (with nitrile rubber as an option), a wide base, low discharge for stability, and an adjustable handle. Constructed from aluminum and stainless steel.
• 2000 Series Dewatering Pumps: Capable of handling chemically aggressive, mechanically abrasive, or highly viscous fluids with particles. Available in lightweight aluminum or corrosion-resistant cast iron, with options for stainless steel impellers.
• Stainless Steel 2700 Series Dewatering Pumps: Constructed entirely from stainless steel to handle corrosive and abrasive liquids, suitable for pH values between 2 and 10.
• Stainless Steel 2700 Series Sludge Pumps (VORTEX Impellers): Stainless steel construction with vortex impellers for sludge applications.
• 3000 Series Sludge and Solids-Handling Sewage Pumps:
  • Stainless Steel Models: Include CS (open impeller with diffuser) and DS (vortex type impeller) versions. Larger CS models feature closed, solids-handling impellers with wear rings.
  • Closed Impeller Models: Cast iron construction with closed wastewater impellers, often featuring stationary brass or nitrile rubber wear rings, and sometimes stainless steel rotating rings for enhanced wear reduction.
  • N-Pump Sewage Pumps (N–Impellers): Equipped with "self-cleaning" N-impellers that prevent solids build-up, reduce clogging, and maintain long-term efficiency. These are cast iron pumps with semi-open, backswept multi-vane impellers.

Operating Limits & Options

• Warm Liquid Versions: Many models are available with a warm liquid 70ºC version.
• Hazardous Environments: Explosion-proof versions are available for various series, approved by Factory Mutual, European Standard, and IEC.
• MSHA Approval: Specific models across different series offer MSHA-approved variants for mining or landfill dewatering.
• pH Range (Stainless Steel 2700 Series): Ideal for pH values between 2 and 10.

Electrical & Mechanical Features

• Motor Insulation: Stator windings are trickle impregnated in resin (Class H insulation), rated at 180°C (355°F), and designed to enable up to 30 starts per hour.
• Bearings: Durable bearings provide a minimum service life of 50,000 hours.
• Cable Entry: Water-resistant cable entry provides both sealing and strain relief functions.
• Compliance: Each pump is tested and approved in accordance with national and international standards, including IEC 34-1 and CSA.
