KDP are a range of mechanical diaphragm pumps. They incorporate a heavy duty gearbox coupled to an eccentric block to actuate the diaphragm, making them appropriate for heavy-duty applications. The pump is belt-driven with pulleys which enable it to use a variety of drive options, including electric motors and petrol and diesel engines for 2” and 3” pumps. With the ability to self-prime, handle solids and run dry, they have a wide range of applications.

The Wilden “Advanced” series of metal pumps features a bolted body design. The bolted configuration on the Wilden AODD pumps deliver better leak resistance at higher pressures than traditional clamp-banded designs. The Advanced series metal pumps are offered in die-cast aluminium, stainless steel and Ductile iron. A variety of options such as ANSI and DIN flanges, NPT/BSPT threads, and specialised air distribution systems are available.

The Wilden “Advanced” series of Air-Operated Double-Diaphragm (AODD) bolted plastic pumps were specifically engineered for maximum performance and efficiency in a variety of applications. Price, chemical compatibility and mobility are important considerations in choosing a plastic pump over a metal pump. Some pumping applications require a pump that is mobile and available in multiple locations. The Wilden Advanced Series AODD plastic pump is lighter compared to metal pumps and is easier to transport. When chemical compatibility is critical, plastic AODD pumps provide an outstanding option over metal pumps that are incompatible with certain chemicals. The bolted configuration ensures total product containment while the optimized liquid path reduces internal friction to maximize output and efficiency. The plastic pumps are offered in polypropylene, PVDF and Teflon, with a variety of outlet options, such as ANSI and DIN flanges, and specialised air distribution systems.

The Wilden “Original” series of metal Air-Operated Double-Diaphragm (AODD) pumps are perfect for demanding applications that require a robust design and long-term dependability. The clamp bands come off quickly and easily for replacement of diaphragms and cleaning. The clamped series are generally cheaper than the bolted series. The Original series metal pumps are available in aluminium, stainless steel and Ductile Iron. A variety of options such as ANSI and DIN flanges, NPT/BSPT threads, and specialised air distribution systems are available.

All Yamada Air Powered Double Diaphragm Pumps feature bolted body construction, which eliminates leaks and simplifies post-maintenance reassembly. Bolted construction is generally superior to clamp band retainers, which frequently require frustrating, unnecessary leakage rebuilds from misalignment during reassembly.

One of the more difficult tasks in selecting a pump for long, trouble free service is the proper choice of both wetted and non-wetted pump components. Pump components wear, and the objective is to get the longest life from the wearing parts. Knowing how to han-dle abrasive and corrosive fluids will lead to proper wetted materials selection. When selecting a pump for corrosive service most use chemical compatibility charts and graphs for selecting and recommending pump materials of construction. These charts; at best, are meant as ever so general guidelines. Practical experience, and past history will dictate the use of certain materials with various fluids.

Yamada Powder Pumps were specifically designed to move bulk solids more effectively throughout your process. They are a cost effective replacement for Augers and Conveyors and eliminate unsafe and labour intensive means of moving bulk powders. These heavy duty pumps consistently transfer fine-grained (100um or finer), low bulk density (5 to 50 lbs. / cubic foot), dry powders in a dust-free operation.
