Description/design

Submersible sewage pump as submersible monobloc unit for stationary and portable wet well and dry well installation.

Hydraulics

The outlet on the pressure side is designed as horizontal flange connection. 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)
  • Four-channel impeller (V)

The sewer hydraulics are equipped with an impeller wear ring and casing wear ring made of hardened material. These contribute long-term to ensuring the uniform efficiency of the unit and minimizing maintenance costs.

Motor

Surface-cooled motors (T motor) do not have a cooling system of their own and emit their heat directly to the surrounding fluid via the housing parts. The motors can therefore be used in immersed state for continuous duty. Depending on their size, they can also be used in non-immersed state for short-time duty.

The self-cooling motors (FK, FKT, HC motors) have an active cooling system and transfer their waste heat to the medium being pumped by means of an integrated heat exchanger. Therefore, these motors are suitable for continuous duty in immersed and non-immersed condition, and therefore also 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 optionally be monitored with a rod electrode. All filling fluids used are potentially biodegradable and environmentally safe.

The connection cable has bare cable ends and a length of 10 m or a customer-specific length. The cable inlet on T, HC and FKT motors is longitudinally watertight.

Seal

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-acting mechanical seals
  • Version K: Block seal cartridge with two independently acting mechanical seals

High efficiency motors

In addition to the standard motors, high-efficiency motors with IE3 classification (in accordance with IEC 60034-30) are also available. As these have the same basis as the standard motors, they have the same features and functions. This means that the same hydraulic systems are also available.

Ex-approval

The motors are available with the following ex-ratings:

  • T motor: ATEX, FM, CSA
  • FK motor: FM
  • FKT motor: ATEX, FM
  • HC motor: ATEX, FM
