The Wilden Advanced FIT pumps feature bolted product containment and easier maintenance. No repiping necessary, the Advanced FIT pumps precisely fit bolt-to-bolt and pipe-to-pipe in existing fluid-handling piping systems. The FIT pumps come equipped with the wetted path that minimizes the number of fasteners and allows for single socket reassembly for faster, easier maintenance. These pumps also come equipped with the energy-efficient Pro-Flo Shift air distribution system.

The “D” in AHD stands for Duplex, which means the reinforcement of the drive pressure is more than 2:1 by the internal pressure boosting stage. This is achieved thanks to a maximum drive pressure of 7 bar (100 psig), which allows the AHD to build up discharge pressures up to 15 bar (218 psig). AHD Series pumps are available in three sizes (AHD 15, 25 and 40) with maximum capacities of 4, 10 and 20 m3/h (17, 44 and 87 gpm).
The new AHS Series, which does not include an internal pressure booster, features an extremely rugged housing making it suitable for higher discharge pressures. The “S” in AHS stands from Simplex, meaning the drive pressure is transferred to the medium in a ration of 1:1.
The 420/430 Advanced FIT pumps have been specifically designed to be direct replacements for existing 38 mm (1-1/2”) pump installations. The release of the aluminum 420/430 Advanced FIT pumps now completes the Advanced FIT pump line, which is available in 38 mm (1-1/2”) through 76 mm (3”) sizes with either aluminum or stainless steel wetted path options.
Almatec, manufacturer of sanitary air-operated double-diaphragm (AODD) pumps, is pleased to announce that its plastic and metal AODD pumps are now 1935/2004/EC-compliant.
1935/2004/EC is the common name for European Commission Regulation No. 1935/2004, which is the European safety standard for materials that come into contact with food during the production process. With this certification, Almatec AODD pumps are now available for use in a wide variety of sanitary and hygienic applications that involve food contact.
Wilden was founded in 1955 by Jim Wilden when he revolutionized the pumping industry by inventing the air-operated double-diaphragm (AODD) pump technology. Since that time, Wilden is providing innovative solutions for a wide range of applications in the energy, chemical, process and water & wastewater industries. Wilden became part of PSG in 2008, and now spans more than 160 countries with more than 180 distributors worldwide.
The two new 1-1/2-inch (38 mm) high pressure bolted metal AODD pump models feature redesigned liquid paths to reduce internal friction to maximize output and efficiency. They are shear sensitive, dry-run capable, externally serviceable, completely submersible and comply with all CE and Atex requirements. These pumps also come equipped with the Pro-Flo Shift air distribution system.
The two new high pressure pump models are
- the HS400S, which is available in aluminum, and
- the HS430S, which comes in stainless steel.
The Stallion series are developed for pumping fluids with high solid content. A shock-absorbing polyurethane screen base absorbs the impact from constant assault by solid particles. The pumps also feature a large internal clearance and flow-through design to keep the pump from clogging; an integrated suction strainer; and an altered ball/seat check valve assembly. These pumps are made for rugged utilitarian applications that require a robust design.
Stallion pumps now also come equipped with the Wilden Pro-Flo Shift ADS.

- 1935/2004/EC and
- FDA CFR 21.177
requirements for use in a wide variety of hygienic applications. These metal AODD pump models utilize the energy-efficient Pro-Flo Air Distribution System (ADS).
The new Wilden air-operated double-diaphragm (AODD) pump series 430 and 830 Advanced FIT is produced of 316 stainless steel for higher corrosion resistance in aggressive chemical applications. These sieries have been specifically designed to be direct replacements for existing Wilden 38 mm (1-1/2”) and 51 mm (2”) Advanced pump installations.
- bolt-to-bolt and
- 316 stainless steel and
- polypropylene plastic materials of construction,
- joining the original aluminum and nickel-plated aluminum offerings.
The introduction of the stainless steel and plastic options allows Wilden AODD pumps to be offered for a greater number of applications, including
- sanitary (food & beverage, personal care products and pharmaceuticals),
- hazardous chemicals and
- corrosive environments.
