'OR' MOTORISED BARREL PUMP / ROTARY BARREL PUMP, then you should give a serious consideration to Diaphragm Hand Pumps, which are low-cost and with zero running expense, with simple design,

1: Introduction: 1. Why a Hand Pump? 2.Why a DIAPHRAGM HAND PUMP 3. Why a Hand Operated Hand Pump 4. Conclusions

1. Why When asimpleandlow-cost solution is required for non-continuous,medium capacity oroccasional pumping duties, or where electric power is a problem, a hand operated pump is anideal choice.

2. Why aDiaphragmHand Of all hand pump designs, a   diaphragm type hand pump design has following advantages a.High capacity b.Simple design   c. Only one wear-out part d.Self priming   capability e. It can rundry (without   liquid)without   damage f. Glandless, no leakage g. It has ability to handle all types of   liquids ranging fromclearliquids to slurries and viscous liquids,   liquids containing solids etc. It really pumps liquids like a   guzzler h. Easy passage of   liquids, no clogging and  jamming. i.No friction, ideal   for inflammables,   explosive liquids, such as solvents and for flame-proof plant   conditions j. No maintenance, not even   lubrication! Quiet operation!!

3. Why a Diaphragm Hand Pump?  Following features have been added to our Diaphragm Hand Pump a.Four body material options, to handle   all types of liquids and chemicals.

b.Six rubber material options, to handle all types of liquids and chemicals.

c.Three sizes: These offer   end user flexibility of choice, as per their requirements of capacity and head.

d.Trolley     mounted design for portability(fixed mounting is     optionally offered).

e.Trolley is made   from steel sections and tubes, for long life

f.A long leverenables operation in   normal upright   standing position.

g.Diaphragm Movement Limits: These   limits prevent   overstretching of diaphragm on upper and lower end ofmovement of   strokes. This extends   life of diaphragm considerably.

h.Hose guide and support: These   supports facilitate slipping of hose on nipple, and alsobear weight of   hose, which in turn protect nipples from breakage, due to weight or movement   of hose.

i. Ready-to-use   supply: It is supplied with all the accessories, and you have to just slip tubes   on suction and delivery nipples, and start using it. It can be used by   unskilled workers.

4.Conclusions: a. Features described above   are not   offered in all of Diaphragm Hand Pumps, available anywhere in the   world. b. We are a company whose only product is this, and are fully dedicated to   quality manufacture of these pumps. c. With these, we offer world's best and widest range   of Diaphragm Hand Pumps. d. If duty   conditions are withinspecification of a   Diaphragm Hand Pump, then it is a lowcost, simple and easyto operate,   substitute/standby for Air Operated Double Diaphragm Pumps, such as Wilden Pump, Yamada Pump, Aro   Pump, Sand Piper Pump. e. It is a truly   multipurpose pump, and it is good to use one for many end   uses.

APPLICATIONS OF DIAPHRAGM HAND PUMP: 1. Empty / Fill Drum / Barrel 2. High-Head Transfer 3. In-Plant Transfer 4. Trash Pump 5. Effluent Pump 6. Irrigation Pump 7. Pump Acids / Alkalies / Solvents / Slurries / Oils  etc., 8. Pump Sensitive Liquids 9. Pump in Bio Gas Plant 10. Essential Oils, Food, Milk Products, Juices 11. Abrasive Liquids, Machine Coolants, Waste Liquids

Pump for acidsand chemicals  For handling and dispensing of Acids and corrosive liquids, such as HydrochloricAcid (HCl), Nitric Acid (up to 50%), Dilute Sulphuric Acid (0-60%), Diaphragm Hand Pump in Polypropylene (PP) is used ( Size 1"-25 LPM, Size 1.5" 50 LPM).

For Conc. Sulphuric Acid 98% pump in Alloy-20 is used (Size 1"-25 LPM). For most of corrosive chemicals, polypropylene is suitable. However, it is advised that details of chemicals, be furnished at enquiry stage itself. Rubber part selection is important, especially for chemicals. For all alkalis, pump in PP/SS316 are suitable. These materials are anticorrosive and hence suitable. Diaphragm Hand Pumps are also used in the chemical process industry, for occasional sampling / injection / dosing / metering pump duty (manually, approximately).

Drum unloading - asa barrel pump / drum pump One of the most popular applications of Diaphragm Hand Pumps is in emptying drums, barrel and carboys

It can handle all types of liquids, such as clear liquids, liquids containing solids, latexes (shear sensitive liquids/ thixotropic liquids), slurries, corrosive liquids. It is ideal for handling of inflammable liquids, such as solvents, as its operation is without friction, and hence is suitable for flame-proof plant conditions It is self priming and requires no special mounting. Just dip suction tube in the barrel and apply handle. It can suck out last drops of liquid from drum 1" or 1.5"  pump is recommended for this duty. It is a low cost substitute for motorized barrel pumps such as Lutz, Graco etc. It can empty a 55 Gallon (200 litres) drums in 8 minutes (1" pump) or 4 minutes (1.5" pump).

High-head transfer Diaphragm Hand Pump is ideally suitable for transfer of liquid directly from barrel to heights of up to 30 feet, and over very long horizontal distances.

For transferring to height, 1" model is recommended. This feature is ideally suitable for transfer of water, fuel, chemicals, diesel, kerosene, gasoline etc. It is better substitute for rotary hand pump, piston hand pumps, in operation and in speed.

In-planttransfer or in-plant transfer duties, Diaphragm Hand Pump offers a simple solution.

Just take suction and delivery tubes to respective vessels, and apply handle and the transfer gets done. It is used for siphoning of mother liquor, in intermittent plant duties, in smaller jobs and in batch chemical processes and as emergency standby. When duty conditions match, it forms a low cost substitute/auxiliary/stand-by to chemical process pumps such as Vanton Pump, Fybroc Pump, Durion Pump etc.
