Graco Husky AODD pumps are excellent alternatives to Wilden AODD pumps. In fact, they are superior in some aspects and can be 30% more efficient in some instances.

Below is a table of common Wilden pumps and their Graco counterparts.

Due to their versatility, Wilden Diaphragm Pumps are suitable for use in a wide range of industries.

ENERGY

Wilden’s pumping solutions are leading the way in energy efficiency in storage terminals, biofuels and solar cell manufacturing. Wilden diaphragm pumps play a vital role as transfer points from one mode of transportation to another and as safe, secure storage locations until product transfer is needed. Wilden is also committed to helping build a clean energy economy through the use of biofuels.

Typical Applications Handled:

PROCESS

Wilden is a recognized leader in the process industries as you can find Wilden diaphragm pumps in many of the top chemical, food and beverage and pharmaceutical plants around the world.

Typical Applications Handled:

HYGIENIC

Wilden offers a wide range of hygienic and bio-pharmaceutical pumps for various food, beverage, dairy, personal care and pharmaceutical applications. When it comes to safety, performance and gentle transfer solutions, trust Wilden: the evolution of clean.

Typical Applications Handled:

WATER/ WASTEWATER

Wilden plays a critical role in handling and transferring fluids used in municipal and industrial water and wastewater plants.

Typical Applications Handled:

The Wilden range has the widest of pump materials of construction options available in the field of air operated diaphragm pumps.

ELASTOMERS

• Neoprene: An excellent general purpose diaphragm for use in nonaggressive applications such as water-based slurries, well water or sea water. Exhibits excellent flex life and low cost.
• Buna-N: Excellent for applications involving petroleum/oil-based fluids such as leaded gasoline, fuel oils, hydraulic oils, kerosene, turpentines and motor oils.
• EPDM: Excellent for use in applications requiring extremely cold temperatures. It may also be used as a low cost alternative for pumping dilute acids or caustics.
• Viton®: Excellent for use in applications requiring extremely hot temperatures. Viton® may also be used in aggressive fluids such as aromatic or chlorinated hydrocarbons and highly aggressive acids. PTFE would normally be used with these aggressive fluids as its flex life is better than Viton®; however, in applications involving suction lift outside the range of PTFE, Viton® will be the preferred choice for highly aggressive fluids.

THERMOPLASTIC ELASTOMER (TPE)

PTFE ELASTOMERS

• PTFE: Excellent choice when pumping highly aggressive fluids such as aromatic or chlorinated hydrocarbons, acids, caustics, ketones and acetates. Wilden’s legacy PTFE diaphragms exhibit good flex life; and now Wilden has coupled its knowledge of PTFE with over 55 years of diaphragm testing to bring a “full-stroke” length option for maximum yield and high suction lift, for the world’s toughest applications.
• Wilden also offers PTFE integral piston diaphragms that offer superior product containment. The smooth contoured shape makes this diaphragm an excellent choice for sanitary or ultra-pure applications.

SANITARY

The Wilden diaphragm pump range is ably supported by a range of accessories that complement air operated diaphragm pump function & capability. Wilden’s accessory products add value to your liquid process and expand the application range of Wilden diaphragm pumps by augmenting the performance and/or utility of the pump. Our electronic controllers automate your Wilden pump for batching and other electronically controlled dispensing applications. We can also create laminar process flow by eliminating pump pulsation or control the liquid level within a system of process.

SD EQUALIZER® SURGE DAMPENER

An inherent characteristic of reciprocating pumps is the pressure change between each pump stroke. The Equalizer® can be used to provide a supplementary pumping action between pump strokes, thus minimising pressure fluctuation while offering protection to your pumping system. The Equalizer® reduces water hammer, absorbs acceleration head, lowers system maintenance costs and minimises pipe strain protecting in-line equipment. Sizes available are SD1⁄2 13mm (1⁄2″) inlet/discharge, SD1 25 mm (1″) inlet/discharge, SD2 51 mm (2″) inlet/discharge and SD3 76 mm (3″) inlet/discharge.

WILDEN DRUM PUMP KIT

The inherent features of the Wilden air-operated pump and Accu-Flo™ pump technology allow it to excel as a utilitarian drum pump. Various speed and pressure capability, the ability to run dry, self-prime and dead-head offers you flexibility at a low cost. The Wilden universal drum pump kit enables Wilden ¼” and ½” pumps to adapt directly to drums for cost-effective, efficient liquid transfer.

• Universal kit for 6 mm (1/4″) and 13 mm (1/2″) pumps
• Fits 51 mm (2″) NPT bungholes
• Tube length can be cut to length
• Variety of materials are available

WILDEN WIL-GARD III

The Wil-Gard™ detects diaphragm failure at the source: the primary diaphragm, not at the air chamber or the air exhaust as other systems do.

• Sensors are located between the primary and back-up (containment) diaphragms.
• When the sensors detect a conductive liquid, an audible alarm, LED and an internal latching relay are activated.
• Increase containment, reduce fugitive emissions and reduce downtime with 24-hour pump surveillance.
• Power requirement: 110V AC, 220V AC or 9V DC battery

WILDEN PUMP CYCLE MONITOR

The PCMI counts pump cycles by sensing the presence of the air valve piston (Turbo-Flo™) or air valve spool (Pro-Flo™).

• The sensor, located at the air valve and cap, detects the presence of a magnet located at the end of the air valve piston/spool
• The PCMI registers a complete pump cycle when the piston/spool shifts away from the sensor and subsequently returns to the original position.
• The PCMI unit has a reset switch located on the face of the PCMI module.
• PCMI has the ability to be reset from a remote location.
