W60

Widethroat type inlet allows gravity flow of highly viscous (plastico-viscous) material on to Augur-on-coupling rod which pushes the substance to the pumping element. Available in close couple and bareshaft configuration.

Viscosities: upto 125,000 cst
Temp: upto 150°C / 302°F
Solid Handling Capability: upto 12%

ROTOFLOW

INDUSTRIAL PUMPS

Progressive Cavity Pumping Principle
The pumping element comprises a precision machined single external helix metallic rotor and a double internal helix elastomer stator. Due to special profile of Rotor and Stator, a sealing line is formed along the axis of the rotor, which is maintained at static or dynamic condition. As the rotor turns within the stator, these cavities progress from the suction to the discharge end of the pump carrying the fluid.

Distinctive design features & benefits
Positive Displacement: Head developed is independent of speed whereas capacity is proportionate to speed. Delivers uniform, metered and non-pulsating flow.
Self-Priming: Inherently self-priming, can work on snore and does not require foot valve.
Non-Clogging: Handles solids in suspension or mixture containing high percentage of solids.
Low NPSH Requirement: Suction lift capability up to 9.5 mwc and effective even in high vacuum conditions.
Low Internal Velocity: Minimum degradation of shear sensitive media.
Reversible: Provides flexibility in operation.

BENEFITS

Tapered Entry Sensor
Facilitates easy entry for fluid and improves suction capability

Improved Pump Housing
A sloped housing design reduces entry losses and facilitates easy drainage. Its flexible housing orientation allows the suction port to be rotated in steps of 90° to suit any installation

Smarter Shaft Sealing
The externally mounted stuffing box enables easier maintenance of Gland Packing or Mechanical Seals, without the need to dismantle bearing housing

Tougher Bearings
The use of taper roller bearings in medium and large size pumps ensures rigidity and concentricity of shaft leading to longer service life.
Smaller size pumps are fitted with heavy duty radial ball bearings

Optimised Rotor-Stator Geometry
Improved Rotor – Stator geometry minimises wear due to lower rubbing velocity as compared to conventional geometry, particularly useful in abrasive applications. Lower starting torque and effective sealing line (zero leakage) improves volumetric efficiency resulting in reduced power consumption and extended service life.

The Cardan Universal Joint
The Cardan type universal joint used in this pump is acknowledged as far superior to the conventional gear joint or single pin & bush joint, having only line contact, which is subjected to extreme concentrated load, resulting in higher wear rate. The Cardan type of UJ joint employs two sets of pins perpendicular to each other, each providing freedom of angular movement which facilitates smoother transmission of angular load and is designed to withstand the axial forces, dominant in Progressive Cavity Pumps.
