Mechanical / Hydraulic

• Cutting System:
  • PE and S series: Features a lobed rotor cutting element attached to a centrifugal impeller, working in tandem with a stationary cutting element fastened to a spiral-grooved bottom plate. The lobed rotor turns inside a stationary cutter designed with wave-shaped castellations.
  • S series (High Head): Features a two-blade, two-stage, primary cutting element attached to the first-stage centrifugal impeller, working in tandem with a stationary cutting element fastened to an adjustable bottom plate. The second stage further shears particles to a very fine pulp.
• Installation Configurations:
  • Fixed installations with pedestal (guide rail assembly)
  • Freestanding, transportable applications
  • Installation in areas where large fluctuations in terrain elevation are present
• Discharge: Small diameter discharges (DN32/1-1/4” threaded and DN50/2” flanged).
• Materials:
  • Motor housing, volute, impeller, bottom plate: Cast iron EN-GJL-250 (ASTM A-48, Class 35B)
  • Rotor shaft: Stainless steel 1.4021 (AISI 420)
  • Fasteners: Stainless steel 1.4401 (AISI 316)
  • Mechanical seal: Silicon carbide
  • Rotating and stationary cutters: Stainless steel 1.4528 (AISI 440B+Co), 58-62 HRC
• Shaft Sealing:
  • PE series: Double mechanical seals, Silicon carbide/silicon carbide (SiC/SiC) provides maximum resistance from abrasives and chemical resistance in wastewater and most other industrial applications. Includes a seal protection system.
  • S series & S series (High Head): High quality SiC/SiC mechanical seal. Motor-side sealing provided by an oil lubricated lip seal arrangement.
  • Seal leak detection system: Provides advanced warning for seal repair prior to water entering the motor (not available for Piranha 09).
• Bearings: The stainless steel motor shaft is supported by lubricated-for-life, heavy-duty, ball bearings.
• Adjustable Bottom Plate: Allows for easy restoration of optimum clearance between the bottom plate and impeller to counter the effects of wearing and to maintain efficiency.

Electrical

• Motor:
  • PE series: Premium Efficiency Motor (IE3) in accordance with IEC 60034-30.
  • S series & S series (High Head): Water-tight, fully encapsulated, flood-proof motors.
• Cable Plug:
  • PE series: Connection between the cable and motor is by means of an integrated 10-pole, quick disconnect, terminal block.
  • S series & S series (High Head): Connection between the cable and motor is by means of an integrated pin-style, Easy-Fit terminal block (non-EX/FM models for S series).
• Temperature Monitoring: Thermal sensors are embedded in the stator windings and can be used to shut the pump off in case of overheating and automatically switch back on once cooled.
• Built-in Capacitor: Available on Piranha 08 and 09 models (S series), which does not require a control box.

Certifications

• Explosion Proof (optional):
  • ATEX (EX II 2 G k Ex d IIB T4)
  • FM (Class 1, Div. 1, Groups C&D)
  • CSA standards
  • Available as an option on most models.
