Non-Metallic Pumps

Investa Pumps is a leading manufacturer of Centrifugal Chemical Process Pumps in specialized Fluoropolymers (PVDF—PolyVinylidene Di Fluoride) for handling various high corrosive liquids. The company has been serving nearly 80% of the Indian Steel industry and chemical industries since last two decades. PVDF offers the specific advantages of easy processing in accordance with all the conventional methods used in plastic industry. PVDF offers a high degree of crystallinity to the other process which results in superior thermo-mechanical properties.

• Resistance to most chemicals and solvents
• High thermal stability- continuous running up to 120C temperature
• High purity and greater mechanical strength at elevated temperatures.
• High abrasion resistance and resistance to sunlight
• Resistance to nuclear radiation and fungus
• Low permeability to most gases and liquids
• Low flame and smoke characteristics

The thick walls casing liner and back plate is of Poly Vinyli Dene fluoride [PVDF] Casing liner is covered in a standard shell of cast iron. Casing Liner and Back Plate are solid injection molded in our factory at Valsad. The impeller provided is semi-open type. A large metal insert in the PVDF impeller greatly increases its mechanical strength and provided long life of service. Bearing Pedestal includes a rigid shaft of high strength Stainless Steel EN-8/ EN-19/EN-24/EN-41 and a double row ball bearing with extremely high load capacity. Envelope gasket provided is of Poly Tetra Fluoro Ethylene [PTFE] with EPDM rubber insert to ensure maximum sealing.

Due to the large cast iron armor over the liner and large metal impeller core, the PVDF used in Fluorolined Pumps can be stressed to a relatively high extent without becoming mechanically over loaded. The Back Pull Out design offer easy maintenance. The pumps and base frames are externally protected from corrosion by a layer of Epoxy paint.

The pumps are manufactured in 20 models with maximum interchangeability. The pumps are suitable for flow rate up to 400 m3/hr with head being 100 mts of liquid column.
