Vertical Glandless Pumps

These Vertical Glandless / Sealless Pumps are specially design to remove the problems arising from the use of Mechanical Seals, Stuffing Box Gland and Dry running in all types Centrifugal Process Pumps. These pumps have no Mechanical Seal or Gland. The Pumps are having similar design to any conventional Centrifugal Pump.

SPECIFICATION:

• Capacity : Up to 200 m3/hr

• Head : Up to 100 meters

• Temperature : Max. up to 100°C

• Maximum Working Pr : 10 bar

• Max. Sp. Gravity : 1.2-2.0

• Viscosity (upto) : 150 mPas (cP)

APPLICATION:

• Mainly for handling Highly Corrosive & Abrasive Slurry (20 %)

• Effluent and Water Treatment Plants

• Gypsum Slurry, Lime Slurry based liquid

• Handling Acids and Alkalis

• Phosphoric Acid plants

• Gas Washing Plants & Rayon Plants

• Chemicals, Dyes & Pigments Industries

• Organic/Inorganic Chemical Industries

• Pickling in steel Rolling mills

• For Descaling & Electroplating Plants

• Fertilizer & Agro – Chemical Plants

• Textile, Pulp and paper industries

• Caustic Soda & Chlorine Plants

• For Scrubbers, Filter press,etc 

These pumps operate on the same basic hydraulic principles as conventional centrifugal pumps, while incorporating a unique design that enhances reliability and reduces maintenance. In a typical pump, liquid tends to pass through the point where the impeller shaft enters the backplate (stuffing box). In this design, such leakage is effectively controlled by diverting the fluid and returning it to the suction tank as a regulated flow.

SPECIFICATION:

• Operating Speeds: 1450 RPM and 2900 RPM

• Impeller Options: Multiple impeller diameters available for each pump size

• Maximum Flow Rate: Up to 100 m³/hr

• Maximum Head: Up to 50 meters

APPLICATION

• Suitable for phosphoric acid applications (H₃PO₄, H₂SO₄, HF and mixtures) with solids up to 40% concentration

• Handles corrosive and abrasive media, including gypsum-containing solutions

• Ideal for gas washing systems handling scrubbed liquids with F, Cl, SO₂, ammonia, etc.

• Capable of pumping fluids with suspended solids

• Used in rayon plants for spin bath solutions (H₂SO₄, ZnSO₄, Na₂SO₄)

• Applicable in caustic soda plants for chlorinated brine and concentrated acids (HCl, H₂SO₄)

• Suitable for metal refineries and pickling installations

• Used in paper and fertilizer plants

• Designed for a wide range of chemical process industries
