Progressive Cavity Pumps

Progressive Cavity Pumps

Progressive Cavity pumps are of heavy duty construction and are designed to pump ‘tough – to – handle’ fluids with ease. These pumps are used in many areas of Industry. The construction of these pumps is based on the modular concepts and incorporate next generation pumping elements (molded to metal) stator, solid shaft and double sealed Cardan Universal Joints for improved performance and longer service life.

These pumps are available in bare shaft and close coupled configuration. 6 and 8 stages in select sizes. A variety of material of construction, shaft sealing options are also available.

KDA Series

These pumps are made out of Cast Iron Pump Housing and Cast Iron Bearing Housing. Rotors of Hard Chrome Plated Alloy steel , Tool steel , SS 304, SS 316 and the rotating part are of Alloy Steel or Stainless Steel. The universal joints are specialy designed single or double knuckle joints. The Rubber Stator is made out of Natural or Synthetic rubbers like Nitrile, EPDM, Hyplon, Silicon, Neoprene, Viton, Butyle or Hi–Nitrile based on application.

  • Maximum Capacity - 350 Cu M/hr
  • Maximum Pressure - 48 Kg/cm2
  • Operating temperature - 200 Degree C
  • Maximum Solid size - 50 mm
  • Viscocity - 50,00,000 CST

KHA Series

Wettable parts of this class of pumps are made out of SS 304, SS 316 or special Alloys like Alloy 20, Hastalloy.

The Rubber stators are of Natural or Synthetic rubbers like Nitrile, EPDM, Hyplon, Silicon, Neoprene, Viton, Butyle and Hi –Nitrile based on end application.

  • Maximum Capacity - 250 Cu M/hr
  • Maximum Pressure - 48 Kg/cm2
  • Operating temperature - 200 Degree C
  • Maximum Solid size - 50 mm
  • Viscocity - 50,00,000 CST

Metallurgy of rotating parts like alloy steel, tool steel, SS 304 and SS 316 while KX – CF pumps are of complete SS 304 and SS 316 material of construction. Other various options of FRP / Ebonite lined housing with rotating parts in super alloys like Alloy 20, Hastelloy C, Hastelloy B and Titanium are available for highly corrosive applications. Shaft sealing ensured by soft gland packing / mechanical seal. Torsion free metal bonded stator and double sealed universal joints as pin & bush joints or special designs like gear joints or cardon Joints as per customer requirements for longer service life and improved efficiency results in trouble free performance of the pumps.

Salient Features

Non-clogging  : Handles solids in suspension or mixture containing high percentage of solids.

Can work on Snore  : Inherently self-priming.

High Suction Lift  : Low NPSH(R), effective in high vacuum conditions

Minimal Internal Wear  : Gentle handling of shear sensitive and abrasive products because of low internal velocity.

Reversible  : Suction and delivery ends can be interchanged by merely changing direction of rotation of the prime mover.

Versatility  : Handles abrasive, Shear sensitive and Viscous materials, Solids in suspension and Air-solid-liquid mixture.

Material of Construction  : Wettable Housing components Cast Iron, Stainless steel

Rotor  : Alloy Steel, Tool Steel, Stainless Steel, Alloy 20, Hastelloy C, Hastelloy B with Hard Chrome Plating

Rotating Parts  : Alloy Steel, Stainless Steel

Stator  : Natural Nitrile, Neoprene, EPDM, Hypalon, Butyl, Silicone, Viton etc.

Seals : Sealing arrangement by soft gland packing or Mechanical Seal.
