diaphragm pumps Suppliers

Diaphragm Pumps are recommended for hazardous, toxic and poisonous liquids, where leakage is not at all permitted. It have hydraulically actuated diaphragm and a back pressure valve. The main function of back pressure valve is to balance the hydraulic oil in the chamber. The reciprocating plunger transmit displacement through hydraulic oil to the diaphragm, the oscillation of diaphragm produces pumping action on process fluid with help of Non-Return Valve in built at both ends. The diaphragm acts as a perfect seal between the hydraulic oil and the liquid being pumped. Diaphragm pump can be provided with single or double diaphragm; usually Teflon acts as a diaphragm. Its application include in petrochemical and pharmaceuticals industries, crude oil, natural gas, coal, nuclear power etc.

Verderair Double Diaphragm Pump are a type of versatile pump which can handle anything from thin volatile liquid to highly viscous like toothpaste and solid laden material. The production range offers a choice of 7 diaphragm elastomers, 8 ball valve materials and 8 pump body materials. This option covers just about any medium however aggressive it may be. These pumps are available from 1/4" to 3" inlet/outlet sizes with capacities varying from 15 LPM to suit customer requirements. Its application include in transfer of Acids, Caustics, Resins, Inks & Dyes, Solvents, Alcohol etc.

Air Operated Double Diaphragm Pump application include in handling viscous chemicals, slurries etc. It is also used to transfer explosive liquids, solvents, acids and further useful in pharmaceutical liquids creams and compounds. The advantages are it is self priming and hence no need of foot valve, it can be submerge, it has light weight and hence handy in use, the pump can run dry, it can handle 2 to 10 mm size solid particles, it also can be used upto accuracy 3 to 5 %. In short it is a very simple and versatile pump.

Air Operated Double Diaphragm Pump is widely used to handle corrosive and slurries. The important features are it is self priming, it has variable speed, it is easy to maintain, it is flameproof and further it runs dry without damage. The specifications are it has height of 44 cm with a width of 31 cm and depth 24 cm.

Pneumatic single acting diaphragm pump suitable for pumping all types of liquids that can pass through a pipe or a hose. The robust Mandar pump can handle everything from water to sludge in the low flow range and offer versatility in wide variety of applications. The pump is excellent in situation where portable and submersible equipment is necessary. It can run dry without damage to the pump or valves.

DP 100 Diaphragm Hand Pump is a simple and low cost solution for continuous, high flow and occasional pumping duties. It is an ideal choice during load shedding as also field operations where electric or pneumatic power is not available. Being portable and trolley mounted, it can be easily used in many locations. It is widely used in Chemical Industry, Petrochemical Industry, Pharmaceutical Industry, Food Processing Industry etc.

DP 100E Diaphragm Electrical Pump handles all types of liquids and slurries. The important features are it has high capacity, it has low maintenance, it is portable as it is trolley mounted and further it is easy to use. The important specification is that it has a flow rate up to 65 litres/min with 0.5 HP gear motor.

Chemistry diaphragm pumps include evacuating chemically aggressive gases and vapors from such equipment as rotary evaporators, vacuum drying cabinets and centrifugal concentrators. Chemistry diaphragm pumps feature uncompromising chemistry designs. Their construction with fluoropolymers makes them very resistant to chemical vapors from inlet to exhaust and very tolerant to condensates. Pumping chambers are hermetically separated from the drive system ensuring long lifetimes of mechanical parts. Most importantly, diaphragm pumps are oil-free, for vastly reduced service demands compared with oil-sealed pumps. They eliminate the cost of water and its contamination well-known from water-jet aspirators, and the waste-oil disposal of rotary vane pumps.

SV Series Diaphragm Pumps are available in the range of 15 Lpm to 75 Lpm with a maximum vacuum of 27” Hg & pressure of 60 Psig. The choice of series & parallel connection in double-stage models gives selective advantage of flow & vacuum / pressure. They are extremely light weighted due to die cast aluminum construction. It can be offered with Teflon coated or PP wetted parts for chemical resistant applications, chemical resistant models are supplied with flameproof electric motor. These are useful for various applications like Pollution control equipment’s, laboratories, flame photometer, agitation of chemicals etc.

Air operated diaphragm pumps can be used in a variety of installations in numerous applications. The pumps are compatible with a very wide range of chemicals like corrosive and chemical aggressive, high and low viscous, abrasive, shear sensitive, flammable etc. It is widely used in the chemical industry for the transfer of all kind of acids, alkalies, alcohol, solvents and shear sensitive products such as latex and emulsions, as well as chemical waste products.
