Crude Waste and Sewage Handling Pumps

Application

Handling of waste water in sewage treatment plants, breweries, slaughter houses etc.: treated domesti and industrial-sewage, faces, sanitary sewage, mud etc.

Crude Waste and Sewage Handling Pump 1

Design

  • Single stage, non-self-priming centrifugal pump, horizontal or vertical, bigger models with cleaning opening at the casing or inlet-socket. Pump can be delivered with:
    • enclosed single-port, twin-port or three-port impeller
    • open single-port, twin-port or three-port impeller.

  • Kind of impeller depends on required max. solids. Pump can be equipped with an automatic fiber chopping device made of highly wear-resistant cast iron, which prevents fibrous material from clogging the pump.

Connections

  • suction socket axial, discharge socket various possibilities. Flange connection.

Temperature

  • max. 110 °C

Capacity range

  • 5 – 3000 m3/h

Delivery head

  • max. 95 m

Shaft sealing

  • stuffing box, mechanical seal

Materials

  • Casing, Impeller and Wear plate: cast iron, bronze, stainless steel, highly wear-resistant cast iron

  • Shaft: steel, stainless steel

  • Sleeve: chrome steel, bronze, stainless steel

Driver

  • electric motor, diesel engine, electric submersible motor, also explosion and flame-proof motors

Direction of rotation

  • C.W

Power transmission

  • flexible coupling, V-belt, direct flanged i.e., motor shaft = pump shaft

Crude Waste and Sewage Handling Pump 2

Special design

Vertical dr or wet-installation. The top supporting plate is connected with the lantern including the thrust bearing for the drive-shaft. Shaft and motor assembled by means of flexible coupling. Below the supporting plate the shaft protection pipe is flanged. Corresponding to the length, this protection pipe consists of one or several intermediate pipes and bearings, in which the rigid coupled intermediate shafts are supported. At the end is the pump body with inlet casing, pump shaft and impeller. The liquid is pumped out of sidewards pointed discharge socket, or through parallel to protection pipe mounted discharge pipe above supporting plate. Shaft sealing can be delivered with stuffing box, but we recommend mechanical seal or better double mechanical seal with oil filling, because this design is absolutely dry ru proof.
