RETURN SLUDGE PUMPS OF SERIES    PKC-M

Application:

Pump is destined for re-pumping sludge or for internal re-circulation of sludge in sewage treatment plants. Pump is designed for pumping stuffs at small delivery heads. When selecting a pump, the customer is requested to specify his requirements for its parameters thoroughly. This pump is intended for operation outdoors.A pumped liquid:        

-  polluted water – sludge

-  impeller passage-ability Φ50 mm

-  max. density 1,050 kg.m^-3

-  max. temperature 40 °C, pH 4 – 8.5

Design:

Pump has been designed as a monoblock consisting of a submerged electric motor being cooled by a pumped liquid and hydraulic part being separated from the motor by an oil pool, and a pair of mechanical seals. Hydraulic part consists of a three-vane impeller and an axial diffuser. Shape of the propeller blades and arrangement of this pump internal space are destined for pumping liquids with fibrous admixtures.

 Installation:

Pump built-in into a vertical shaft made either of steel pipe or concrete falsework. Fundamental flange separates the suction space from the vertical shaft. Pump can be installed easily and quickly on the steel flange, where sealing of the suction space and its separation from the vertical discharge shaft are ensured by means of o-rings and the pump own weight, without using any bolts.

To realize maintenance, the pump can be lifted simply out of a shaft, by means of a lifting mechanism.

Material options:

Pump casing with electric motor        -    grey cast iron

Impeller                                             -    stainless steel for castings

Diffuser                                             -    stainless steel

Shaft and connection screws            -    stainless steel

First mechanical seal                        -    SiC / SiC

Second mechanical seal                   -    Ni-resist / C saturated by Sb

L_min  - min. submersion of pump into a          

            pumped liquid = 200 mm

L_v  -     discharge part of vertical shaft – length

            according to projection layout on a work

            Total length of vertical shaft for order     

            specification = L_min + L_v

            Material options of a tube – according

            to the customer specification
