Screw Centrifugal Pumps; Screw Centrifugal Submersible Pumps; Submersible Pumps; Heavy Duty Submersible Sludge Pumps

Fluid Solids Handling Pumps - SC Range

Options

Submersible Pump - SSC.
Immersible Pump - ISC.
Vertical Spindle Pump - VSC.

Design

SSC - Based on Standard Submersible Motors as in VX, SSH, Series.
Multiple Impeller Options to meet Duty Point Demand.
Adjustable Suction Liner on Larger Pumps.
Special Quatro Mechanical Seal fitted in Oil Filled Chamber.
ISH – Immersible Oil cooled Stator Housing allow for Drainage down to Volute Level.
Oil Cooling Taking Place on special Back Cover inside Seal Housing.
VSC – Pump with same Wet End, Bearing Housing Quattro Mechanical Shaft Seal only with Shaft Extension and driven by Air Cooled Squirrel Cage Motor.

Mechanical Shaft Seal

Our specially designed Quatro Mechanical Shaft Seal allow for short over hang distance after D.E. Bearing to Impeller.
Tungsten Carbide / Tungsten Carbide (Motor End) and Tungsten Carbide / Tungsten Carbide (Impeller End) is fitted, with O-Rings sealing on Shaft at four places.
Spring Tension is achieved with Metal Bellow which allows for same consistent pressure throughout the Mechanical Shaft Seal arrangement.
No tension variation as in conventional Spring Mechanical Seals where the wire size and coil length differs in every batch.
Oil Submerged Chamber for maximum lubrication and cooling. This arrangement allows for Dry Running without damage to the Mechanical Shaft Seal.
Furthermore the Quatro Mechanical Shaft Seal is pre-screened by two Oil Seals on Impeller Neck which also closes the cavity on Shaft through Back Cover.

Replaceable Back Cover

Not only a cost saver wear part, but also protects the Bearing / Oil Housing from transferred product wear and Volute Velocities.
Replacing allows for OME Clearance on Impeller to Back Cover.
Enable Axis to the Mechanical Seal without major disassembling, Rotating Assembly stay intact.
Special Back Cover is used for ISC Pump to Cool Down Oil.

Impeller

Screw Impeller with different Pitch High Efficiency allow for Large Solid Through let.
The Impeller is fitted to a Shaft Taper and is Key driven, which ensures a strong, high torque fit.
It also prevents the Impeller from turning loose if Pump Motor is run in wrong direction.

Unique Concept

The Screw Impeller on the SC – Range is fitted with an Adjustable Suction Liner.
Clearance is Adjusted to Impeller by means of Push / Pull Concept.
Closer clearance tolerance is achieved than in the case of conventional Spacer Shims.
No Removal of Impeller for Machining or Balancing is necessary in order to achieve OEM Clearances.

Cost Saver

Very close accurate clearance is achieved with this concept. No Dismantling, Machining or Balancing needed in order to achieve High Pump Efficiency.

Strainer

WWW where Sludge and Screened Sewage is Transfer, no Strainers are fitted.
Used in Mining Environment Strainers are Fitted as Solid Sizes can not be determinant.
Different through let Strainers are fitted, depending on the Impeller’s capability.

Installation Options

Submersible 30 meter.
Immersible 20 meter.

Vertical Spindle 14700mm Up to Motor Flange.
For deeper sumps or dams where flooding of motor is a possibility, the SSC Submersible VSC Pump is available with the exact same Wet End (Impeller, Volute and Suction Liner).

Fluid Submersible Motors are used throughout the Range.

In the effect where the SSC Submersible Pump stands a chance of dry running the ISC Immersible Pump can be used, which is Oil Cooled. Oil is pumped from the Oil Housing, which circulates the Motor Stator Housing. The oil is cooled down in a specially designed Back Cover which acts as a Heat Sink.
