Descripción/construcción

Submersible sewage pump as submersible monobloc unit for stationary and portable wet well and dry well installation. Portable installation is possible, depending on type.

Hydraulics

The output on the pressure side is configured as a horizontal flange connection (exceptions: FA 05.11W and FA 05.33E). The maximum possible dry matter content is 8%, depending on the hydraulics and impeller type.

The following impeller shapes are used:

  • Vortex impeller (W)
  • Single-channel impeller (E)
  • Two-channel impeller (Z)
  • Three-channel impeller (D)

The single and multi-channel hydraulics (Z, D) are equipped with a mobile and stationary wear ring (depending on type). These contribute long-term to ensuring the uniform efficiency of the unit.

Motor

Dry motors (T motors) give off their heat directly to the surrounding fluid via the housing components and can be used in immersed state for permanent operation. Depending on the size, they can also be used in non-immersed state for short-term or permanent operation.

The oil-filled motors (F, FK motors) and self-cooling dry motors (FKT, HC motors) give off their heat to the pumped fluid via a built-in heat exchanger. Therefore, these motors are suitable for permanent operation in immersed and non-immersed condition or for dry well installation.

All motors have a sealing chamber that protects the motor from fluid ingress. It can be accessed from the outside and can be monitored with an optional sealing chamber electrode.

All filling fluids used are potentially biodegradable and environmentally safe.

The cable inlet on T, HC and FKT motors is longitudinally watertight. Up to motor size 17, cable lengths are available in fixed lengths measured in 33 ft (10 m) intervals. Starting from motor size 20, the cable length can be individually configured.

Sealing

Fluid-side and motor-side sealing is possible in the following versions depending on the motor type:

  • Version H: Mechanical seal for the fluid side, rotary shaft seal for the motor side
  • Version G: Two independently operating mechanical seals
  • Version K: Block seal cartridge with two independently operating mechanical seals

Materiales

  • Motor housing: ASTM A48 Class 35/40B (EN-GJL-250)
  • Volute: ASTM A48 Class 35/40B (EN-GJL-250)
  • Impeller: ASTM A48 Class 35/40B (EN-GJL-250)
  • Static seals: Nitrile (NBR) or FPM (Viton)
  • Sealing on pump side: SiC/SiC
  • Sealing on motor side: SiC/SiC or C/MgSiO4 or C/Cr
  • Shaft: Stainless steel AISI 420 (1.4021)
