Aodd pump operating principle - Blagdon Pump

IDEX Proprietary & Confidential


Pump Chambers are alternatively filled and emptied by drawing fluid in through

a common suction manifold and out through common discharge manifold.

The diaphragms in each chamber are linked by a common shaft, so that they

move backwards and forwards in unison.

Compressed air is directed by the air valve alternatively, behind each

diaphragm, to power discharge strokes.

Pump speed, fluid output and pressure (or head) is controlled by increasing or

decreasing the flow of compressed air to the pump.


Suction Cycle:

Fluid is drawn into the Suction Manifold at (C), by the suction stroke of the

diaphragm and into Chamber B.

This ‘opens’ the ball valve (2) to allow liquid to enter the chamber.

Ball valve (4) is drawn into the Valve Seat and ‘closed’ by the diaphragm

suction stroke.


Discharge Cycle: In Chamber (A), air has been applied to the rear of the diaphragm to force out

the Fluid in the chamber through the ball valve (3) to the Discharge Manifold (D).

The discharge stroke ‘closes’ the ball valve (1) to prevent further liquid entering the chamber.

This cycle is repeated to provide a continuous flow to the Discharge Manifold at outlet (D).


Air Operated: • No need of electrical drive. • Easy to buy, use and install.

Self Priming: • No need of priming. • Unloading from drums/ sumps etc. • Replaces the traditional drum pumps • Example: Acid and solvents (raw

material) unloading in pharma and refineries


Seal-less Pumps: • Zero Leakage • Less maintenance compared to sealed

pumps • Ideal for corrosive, abrasive, hazardous

liquids handling • Example: Sulphuric Acid, Ink, Solvents

Can be stalled indefinitely: • Can restart automatically when

pressure is released. • Ideal for filling applications • Example: Oil filling lines


Can run at wide variety of flows: • Through air-regulator • No need of VFD • Example: Unloading applications

Can run dry without damage: • No internal pump damage

• Any other seal pump will have seal failures

• Any motorized pump will have motor damage

• In case of PC pump, the whole pump failure

• Example: Viscous liquids/ slurries prone to choking like fruit pulp


Low Shear: • Low velocity and absence of tight

clearances => low shear • Low product degradation and agitation • Example: Paint, Emulsions, Latex

Can handle solids: • No tight clearances • No mechanical seals • Example: Ceramic, waste-water

treatment


Naturally Intrinsically safe -ATEX Approved models: • Safe for using in hazardous environment

Can operate Submerged: • Air supply and exhaust hose will

extend to pump submerged below • Used when lifting from tank below is

not practical


Compact and Portable: • Not anchored to a foundation

• Easy to move • No alignment issues

• Light weight • One pump can be used for many

intermittent services • Example: Sludge removal from tanks
