The Fluorinated Polymer are widely appreciated for their remarkable chemical inertness and their excellent resistance to ageing.
POLYVINYLIDENE FLUORIDE (PVDF) offers the specific advantage of easy processing in accordance with all the convection methods used in the plastic industry. PVDF, polymerized, according to its own special process, offers a high degree of crystallinity to that by other processes, resulting among other things, in superior thermomechanical properties.
The intrinsic technical superiority is one of the reasons for the success which PVDF has achieved on the world market for more than 20 years.

• Easy processing by : extrusion, injection, compression, rotational moulding, blow moulding etc.
• Chemically inert to most acids, aliphatic and aromatic organic solvents, alcohals etc.
• Very high purity.
• Excellent mechanical properties over a wide range of temperatures : tensile yield strength up to 55 MPa at 23C and 10 MPa at 150C.
• Abrasion resistance comparable to that of polyamides, and relatively low coefficient of friction.
• Continuous use at temperatures as high as 150C for the homopolymer grades (without mechanical stress).
• Excellent thermal aging resistance : tensile yield strength retention over 90% after 25, 000 hours at 150C in a ventilated oven.
• Unaffected by UV (>232nm) and good resistance to gamma radiation.
• Excellent intrinsic fire resistance.
• Very easily joined by welding and good capability for thermoforming.
• Physiologically harmless and approved for contact with food products (FDA).

• Tried and tested chemical process pump design for rough conditions.
• Thick-walled vacuum-proof plastic housing in one piece. Therefore no additional sealing points in the pump housing.
• Plastic housing completely encapsulated in a metal armour of tough material.
• Pipeline forces are absorbed by the metal armour.
• Also suitable for high system pressures.
• Flanges with through holes meeting the requirements of the chemical industries.
• Semi-open PVDF impellers reinforced by large metal inserts.
• Smooth running and long service life of the mechanical seal, thanks to the particularly heavy duty bearing pedestal.
• Modular system ensuring economical spare parts stocking.
• External corrosion protection of pump and base plate by an epoxy paint

Pump Casing Linear & ArmourPVDF liner is completely encapsulated in the metal armour (shell). All sealing points are metal supported and "flowing" of the PVDF is thus limited. The robust armour absorbs all the loads in the system and from the suction.

Slide in UnitPump without casing with semi-open PVDF impeller and solid injection moulded PVDF back plate.

Shaft SealingExternal mounted teflon bellow-type single mechanical seal and high alumina ceramic stationery sealing face.

These pumps are most suitable for :-

• Drainage and irrigation installations
• Sewage disposal for housing colonies basement, toilet blocks etc.
• Marine installations

The basic advantages of these pumps are :-

• Economy in floor space
• Prime mover can be mounted at an elevation as shown or at a higher elevation. Higher elevation of prime mover is possible by adding extra adaptors, transmission shaftings and intermediate bearings. This reduces the risk of submerging the electric motor in case of accidental flooding of the dry pit.
• Ease of maintenance. To dismantle, the mounting cover is to be unbolted from the casing after motor has been removed. The rotor assembly is drawn out upwards complete with stuffing box, bearing housing etc. This rotor assembly can then be completely dismantled at a convenient location. Due to the back pull out design, choking of the impeller can also be similarly, removed easily.

Self priming sewage pump is a highly precise and yet a very rugged unit.
The operation of the pump is as follows:A. vacuum pump starts.B. Water level in float chamber rises. Float rises and operates the level switch.C. Vacuum pump shuts down and main pump starts. Whilst main pump is in operation and pump looses prime then the priming pump restarts to automatically maintain the prime. As soon as priming is completed, the vacuum pump shuts down and main pump goes on operating.
In case the level of product in the suction tank goes below the level of the suction line and pump looses its prime, the vacuum pump cuts in. The main pump continues to function for a predetermined time limit-approximately 2.5 minutes. After the predetermined time limit is over, the electric control panel shuts down the main pump motor.
The whole system is absolutely automatic and has been developed after long research, to give outstanding performance under arduous service conditions.

• Seal less design
• Self Priming type
• Light weight & hence portable
• Barrel pumps with their versatility help to provide a complete solution to your fluid management needs
• Modular design construction for easy maintenance
• All components are interchangeable
• Saves considerable time, labour, spillage
• High standards of quality and safety ensures reliable performance for handling aggressive corrosive & flammable liquids.

BARREL PUMPS ARE AVAILABLE IN STAINLESS STEEL SS-316/POLYPROPYLENE/TEFLON MATERIAL OF CONSTRUCTION

Rubberlined Pumps are very good acid handling pumps. These are available in a range of five models, developed with a main objective of attaining higher levels of corrosion resistant durability and interchangeability. These are simple in design, robust in nature and are very reliable.

• These are less expensive than more exotic Stainless Steel & High Alloy Pumps for identical service conditions.
• Interchangeability of parts permits quick servicing of damaged parts in chemical plants & result in minimum spare part inventory.
• Simple external axial adjustment for IMPELLER adjustment.
• Standard dimensions cut layout design cost.
• Standard foundations save installation, drawing time, talent & money.
