You can handle any type of liquid such as clear liquid, liquid containing solids, thick liquids, viscous liquids, liquid containing abrasive solids, acid, alkali, inflammables, solvent, slurry, trash, mud water etc. Regarding viscous liquids, the maximum viscosity that can be handled can be judged by simple thumb rule, "if your liquid can be easily poured from a bucket this pump can handle it
The pump is available in three (3) sizes with following capacity and head.
| Size in Inches Tube ID | Capacity in Litre/Minute LPM | Delivery Head in Feet | Suction Lift In Feet |
|---|---|---|---|
| 1" | 25 | 30 | 12 |
| 1.5" | 50 | 10 | 12 |
| 2" | 100 | 0 (free discharge) | 12 |
- If your duty is of say, barrel unloading, or transfers to height, then 1" size (delivery head, 30 feet), is suitable. If job is repacking, then also 1" size is better suited.
- If the duty is fast transfer, such as tanker unloading, in-plant transfer, siphoning etc. then 1.5" size at 50 LPM, 10 ft. head is suitable.
- If duty is plain emptying or fast transfer at no head, such as pond, cellar or manhole emptying, or that in irrigation, size 2" at 100 LPM, 0 feet (free discharge) head, is better suited.
- All the three sizes offer @ 12 ft. of negative suction in water.
- Along with selecting size, you have to check suitable MOC.
- If in doubt, describe your duty and name of liquid, and we will guide you.
- Cast Iron-Galvanized (rust-free).
- Polypropylene (plastic, glass fibre reinforced, moulded).
- Stainless Steel 316 (Investment cast, graded).
- Nitrile (Buna-N).
- Chloroprene (Neoprene ®).
- EPDM (Nordel ®).
- Silicone.
- Viton ®.
For general guidelines, visit Section 4, on MOC.
For specific liquid/s, you must provide details, like name of liquid, its pH (if acidic), content/s of mixture (if it is a mixture), solids present, if any, nature of solids (soft/abrasive, small/large) etc. for appropriate MOC recommendation. The details are also given in Section 7 Contact us page.
In final selection, MOC of body and rubber parts, both must be suitable for the liquid.
The pump is available in three (3) sizes with following capacity and head.
Life of diaphragm depends upon liquid to be handled and cannot be specified. But in case of our pump we have done some innovative improvisation. We have put diaphragm movement limits on link that connects diaphragm to handle. This prevents overstretching of diaphragm on upper and lower end of stroke. Overstretching is one of the major reasons for diaphragm breakage, and that factor is fully taken care of.
Normally life of diaphragm and flap valves is high, if properly selected. However you may keep one diaphragm in spare. Flap valves wear out only in case of abrasive liquids, or due to chemical attack. Body and its parts do not wear out and hence do not require to be kept as spares.
Except for Viton® rubber parts, all other diaphragms are low cost. Generally speaking, diaphragm needs change only after long usage.
Life of pump body and parts, if not attacked chemically, is long and never require change.
For viscous liquids, a simple thumb rule is, if your liquid pours easily from a bucket, our pump can pump it. Liquids of viscosity like that of castor oil can be pumped by our pump.
Enter Diaphragm Hand Pumps in Google/Yahoo/MSN or any other search engines, and find it for yourself, if anybody else in the world offers such a wide range in Size and in MOC of body and rubber parts and in features. Basically, this is our only product and we are totally focussed on production and marketing of these multipurpose hand pumps. If you are a pump dealer in any country, you are welcome to represent us in your country/territory.
Whenever duty conditions (suction head, delivery head, capacity required) are achievable by Diaphragm Hand Pump, and if manual operation is not a problem, our pumps offer a very low cost option, which we have claimed in our other web pages. However, in case only Air Operated Double Diaphragm Pumps are required, our pumps offer a low cost standby/auxiliary/emergency use option (if duty conditions are met).
- Commission and start usage.
- Operate.
- Maintain
that any unskilled person can do it. We supply it in ready-to-use form. All you have to do is to slip and clamp tubes on suction and delivery hose nipples, and move handle. Pump primes itself and pumping starts.
Delrin is an engineering plastic which offers good strength, but not as much as a metal does. As we offer pumps in Cast Iron and in SS 316, we do not lack in any application, which a pump in Delrin can perform and a model from our range cannot. For chemicals, polypropylene is a far better choice than Delrin is. So application wise, we offer a far wider choice, than a pump in Delrin does.
- Simple design
- Few moving parts
- Minimal maintenance
- Low cost.
No sir, our Diaphragm Hand Pumps, which are rich by virtue of design and additional unique features, are mass produced, and are offered as a low cost product. They are priced low and affordable.
