SERIES 2530 CLOSE-COUPLED SEALLESS MAGNETIC DRIVE PUMPS

  • Capacities to 1500 GPM (350 m3/hr)
  • Heads to 400 feet (125 m)
  • Powers to 100 HP (75 kw)
  • Temperatures to 200°F (93°C)
  • Working Pressures to 200 PSI (1,380 kPa)
  • ASME/ANSI B73.1 dimensioned
  • Materials of construction availability:  VR-1, VR-1 BPO-DMA, EY-2
  • Magnetic drive pump features silicon carbide shaft and sleeve bearing (optional carbon sleeve bearing available). Available in ten sizes with capacities to 1500 GPM and heads to 400 feet.
1. Close-Coupled Design
C-Face motor eliminates need to perform pump/motor alignment. Adapts to NEMA and IEC motors
2. Instrumentation Ports
Two ports provided for performance monitoring.
3. Outer Magnets
High strength Neodymium Iron Boron magnets that provide high torque and hard start capability without slip.
4. Close Clearance Outer Ring
Protects containment shell in the event of a motor bearing failure.
5. Single Axially Clamped O-ring Seal Between Casing and Cover
Fully confined to prevent leakage/blowout
6. Separate Inner Magnet Ring Assembly
Replaceable (removable) from impeller thereby reducing maintenance and inventory costs. Neodymium Iron Boron magnets encapsulated for corrosion resistance.
7. Sleeve Bearing
Sintered silicon carbide for optimum corrosion and wear resistance. Internal spiral groove and face grooves for lubrication and self-purging of contaminants. Porous material structure retains lubricant in the event of liquid loss. Optional carbon sleeve bearing for extended dry-running.
8. One-Piece Reinforced Casing with Integral Flanges
No liner failure concerns. Gusseted flat face flanges meet ASME/ANSI B16.5 Class 150. Also available with ISO/JIS/DIN flanges.
9. ANSI Dimensional Casing
ANSI dimensional requirements permit the maximum interchangeability of pumps between pump manufacturers.
10. Interchangeable Front and Rear Thrust Bearings
Sintered silicon carbide for optimum corrosion and wear resistance. Keyed to prevent rotation.
11. Large Diameter, Stationary, Self-Aligning Shaft Design
Sintered silicon carbide for optimum corrosion and wear resistance. Fully supported by containment cover and suction web and sized to eliminate shaft deflection.
12. Closed Impeller Design
Provides axial balancing eliminating axial thrust loads and extending thrust bearing life. Radial hydraulic forces carried between shaft supports eliminate overhung loads.
13. High Pressure Bearing Lubrication
Utilizes pump discharge pressure to lubricate shaft and sleeve bearing. Clean process fluid is ensured by tight cover/casing clearance filtering occasional solids.
14. Rigid Casing Feet
Reduces the effect of pipe loads on pump and alignment.
15. Casing Thru-Bolts
Double nutted to allow for back pull-out without breaking fluid containment.
16. One Piece Cover/Containment Shell
Thick walled, non-metallic construction that allows for accurate alignment. Eliminates  gasketed joint and energy losses/heat build-up from magnetic coupling eddy currents.
17. Retaining Ring
Reinforced fiberglass construction. Eccentric OD/ID allows for easy installation and rotation to lock into position.
18. Motor Adapter
Rigid Cast Iron. Polyester powder coating for corrosion resistance.

  • Separate impeller and inner magnet ring assembly
  • Replaceable (removable) from impeller thereby reducing routine maintenance and inventory costs
  • Neodymium Iron Boron magnets encapsulated with 1/8″ fiberglass corrosion protection
  • Closed impeller design with low stress hex drive

Figure 2

  • One-piece reinforced (ASME/ANSI dimensioned) casing with integral, gusseted flanges
  • NO SEPARATE LINER FAILURE CONCERNS
  • Expanded suction eye to compensate for suction web, thereby yielding lower NPSH requirements

High Pressure Bearing Lubrication Path

  • Bearing lubrication path taken off of high pressure area
  • Filters occasional solids out of the lubrication flow path
  • Solid size restricted by the nominal 1/16″ casing/cover clearance
  • Sleeve bearing contains an integral spiral groove and face grooves for lubrication and self-purging
    of contaminants

SERIES 2630 CLOSE-COUPLED SEALLESS MAGNETIC DRIVE PUMPS

  • Capacities to 300 GPM (70 m3/hr)
  • Heads to 200 feet (65 m)
  • Suction Lifts to 20 feet (6 m)
  • Two pump sizes

The Fybroc Series 2630 is an FRP, close-coupled, self-priming, magnetic-drive sealless pump that incorporates many of the features found on the Fybroc Series 2530 pumps. With the exception of the casing volute/tank assembly, all components of the Series 2630 are fully interchangeable with those of the Series 2530. The Series 2630 is ideally suited for corrosive sump applications, tank car unloading, and other similar, demanding applications. The volute casing has been designed with optimal proportions in the recirculation chamber to provide for short and efficient priming times, without the use of troublesome check valves. The volute casing inlet has also been designed to minimize NPSH requirements, thereby leading to greater allowable suction lifts.

An important feature of the Series 2630 is its replaceable volute extension. The casing volute cutwater in any self-priming pump must be in close proximity to the impeller in order to permit efficient priming. The removable volute extension in the Series 2630 is available in a number of sizes to match specific impeller diameters permitting field hydraulic changes and the restoration of priming efficiency, all without casing modifications or replacement.
