Air-operated double diaphragm pumps can move anything from fine chemicals (gentle, non-shearing action), to abrasive and viscous slurries (no close-fitting parts, low internal velocities), and almost any other product that can move. A few of the thousands of products now being pumped:

• Paints & solvents
• Pigments
• Resins
• Construction water & waste
• Beer & wine
• Mine tailings
• Chemicals
• Oils & lubricants
• Glues & adhesives
• Dyes
• Foods
• Tanker loading/unloading
• Marine barges
• Ceramic slips, slurries & glazes
• Latex
• Driller's mud
• Inks & printing liquors
• Against filter press
• Low density powders
• Handling Barrels, Jerry Cans, Carbouys.

Versatile Performance

• Can run dry indefinitely without damage.
• No shaft seals or gland packing.
• Infinitely variable flow & discharge pressure from 0 to pump's maximum by adjusting air pressure.
• Gentle non-shearing action.
• If discharge is clogged or closed pump stops immediately; no power consumed, no heat, no wear. By opening discharge, flow starts automatically.
• Operates submerged or with flooded suction.
• Self-priming from a dry start.
• Pressures up to 100 PSI (7 bar).
• No close fit, sliding or rotating parts. Low internal velocity reduces wear.
• Quick assembly/disassembly with split clamp bands.
• Capable of pumping at high temperatures.
• Quiet, steady discharge flow without use of pulsation dampener.
• Safe for use in explosive environments. No electrical hazards or costly motor and control equipment needed.
• No pressure relief or bypass piping required because pump pressure never exceeds air inlet pressure.
• Pollution-free operation. The pump even improves air environment in confined areas.

Air Operated Double Diaphragm Pumps

• The air valve directs pressurized air to the back side of diaphragm 1. The compressed air is applied directly to the liquid column separately by elastometric diaphragms.  The diaphragm acts as a separation membrane between the compressed air and the liquid.  Driving the diaphragm with air instead of the shaft balances the load and removes mechanical stress from the diaphragm, dramatically extending diaphragm life.  The compressed air moves the diaphragm away from the center block of the pump.
• The opposite diaphragm is pulled in by the shaft connected to the pressurized diaphragm.  Diaphragm 2 is now on its air exhaust stroke; air behind the diaphragm has been forced out to atmosphere through the exhaust port of the pump.  The movement of diaphragm 2 toward the center block of the pump creates a vacuum within chamber 2. Atmospheric pressure forces fluid into the inlet manifold forcing the inlet valve ball off its seat.  Liquid is free to move past the inlet valve ball and fill the liquid chamber.

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 23°C and 10 MPa at 150°C.
• Abrasion resistance comparable to that of polyamides, and relatively low coefficient of friction.
• Continuous use at temperatures as high as 150°C for the homopolymer grades (without mechanical stress).
• Excellent thermal aging resistance : tensile yield strength retention over 90% after 25,000 hours at 150°C 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).

Advantages at a Glance

• 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 & Armour
PVDF 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 Unit
Pump without casing with semi-open PVDF impeller and solid injection moulded PVDF back plate.

Shaft Sealing
External 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.

Automatic
Self priming sewage pump is a highly precise and yet a very rugged unit.

The operation of the pump is as follows

• Vacuum pump starts.
• Water level in float chamber rises. Float rises and operates the level switch.
• 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.
