Wilden diaphragm pumps and accessories are suitable for a wide range of fluid delivery requirements, including ultra-clean workshop fluid circulation and mud pumping. Wilton pneumatic diaphragm pump using two pump chamber to reduce the flow rate in the pump, shear sensitive, and the foam phenomenon to the minimum. Because of the lack of tight fitting parts, so can let the particles through the diaphragm pump without damage. Abrasive and viscous materials can also be easily pumped without compromising liquid properties. Diaphragm pump in many processes and  fouling application study can idling, self-priming without danger.

Changes in flow and pressure can be achieved simply by adjusting the supply air pressure, volume, and/or output indenter. With no packing or mechanical seal, Wilton diaphragm pumps facilitate the delivery of flammable liquids. The pneumatic design of Wilton pneumatic diaphragm pump has inherent safety.

As you can see, WILTON OFFERS YOU many benefits, not only to maximize your liquid flow system, but also to reduce your investment and maintenance costs.

Advantages of the WILDEN pump

Unbalanced valve patented design, will not stop unbalanced piston, no dead point

Plastic self lubricating air system, no need for oil lubrication

Minimum energy consumption, very low compressed air leakage

Special fast exhaust structure, fully ensure that the air valve does not freeze, improve the air utilization rate

The number of parts and wearing parts in the single pump is the least in the industry, unique clamp design, fast and convenient disassembly

The patented stiffener design gives the WILDEN diaphragm the longest life and highest temperature resistance in the industry

Passed ISO9001 certification, and the European Community CE certification

The universal advantages of pneumatic diaphragm pump

No electric spark, can run empty, can be self-priming start work, without complex control, simple operation, self-priming height up to 6M

Can be selected by the shell of the pump body and diaphragm material to transport different characteristics of strong acid, alkali, strong organic solvent liquid medium

No dynamic seal, no pollution of the material, low shear force, not easy to damage the material structure

Submersible, mobile, easy handling, can be used as a mobile pump

No rotating parts (or bearings), no mechanical shaft seal, no connectors, low maintenance cost

The delivery speed can be changed by changing the gas volume

The conveying height can be changed by changing the pressure

Can transport high viscosity, high viscosity liquid medium

Can switch the outlet at any time, not afraid of blockage

Automatic pressure balancing (without pressure relief valve)

1. Suitable for the chemical industry in high, medium and low viscosity of all kinds of acid, alkali and corrosive fluid, benzene, ketones and esters and other solvents transport. Due to the use of compressed air as power, flow, pressure adjustment range is wide;

2. It is suitable for the transportation of all kinds of fluids in flammable and explosive environment, because the pneumatic diaphragm pump does not generate electric sparks, does not generate and accumulate heat in the work;

3. It is suitable for the transportation of all kinds of precious liquid, high harm, high corrosion and other dangerous materials in fine chemical industry, because the pneumatic diaphragm pump has no dynamic seal structure, completely separated from the outside world, no material leakage;

4. Suitable for harsh working conditions such as oil fields, mines, construction sites containing solid particles of wastewater, no blockage, no overload, no leakage worries;

5. It is suitable for conveying all kinds of materials in light and mobile occasions without foundation. Small footprint, simple and economical installation;

6. It is suitable for the transportation of high purity and high clean materials, because the pneumatic diaphragm pump does not need lubrication, no lubricant pollution of materials. Such as in pharmaceutical intermediates and products, laboratory pharmaceutical delivery;

7. It is suitable for fluid transportation with unstable chemical properties, because the pneumatic diaphragm pump has very low shear force on the material and does not destroy the material structure. Such as transport photosensitive materials, flocs, crystal liquid

8. With automatic batch pumping and metering functions;

9. It is suitable for feeding pump of plate and frame filter press.

10. Widely used in shipyards, T series Marine pneumatic diaphragm pump, used for conveying sewage oil, because the pneumatic diaphragm pump has strong self-priming ability and conveying materials with a certain viscosity, the maximum self-priming height can reach 7 meters

11, because the pneumatic diaphragm pump may pass certain particles, can idling self-priming, explosion-proof and other characteristics, widely used in coal mine, used to transport sewage
