Completely different and a lot better
The Albin Pump AD is designed for a large capacity and long service life. Compared to traditional AODD pumps, it offers 70% lower pulsation, higher power, noise reduction and 3%u20135 times longer operation time between service intervals. The compact outer measurements and capability to install the pump upside down, sideways or vertically means flexibility during installation and set up. What%u2019s more, it is designed so that all vital parts are easily accessible without having to remove the pump from the pipe system, greatly minimizing downtime. All these improvements result in lower operational costs, reduced cost for spare parts and improved overall economy.

Almatec is one of the world’s leading brands of pneumatic diaphragm pumps. The first pumps were delivered in 1984. The technology is based on decades of experience in the pump sector. Numerous trend-setting developments resulted and the product range diversified to provide solutions to a whole variety of problems.
Since the company was founded, it has produced and delivered over 100,000 pumps.
Models
Verderair offers with the Almatec-series two main ranges of pumps; for standard, and for specific applications.
Standard applications
Pumps for the ‘normal’ applications are extremely suited for pumping all kinds of chemicals, slurries, coatings, paints, solvents, acids, glues, resins and powders.
The pumps are available in several types of plastics (PP, PE, PTFE) but also in stainless steel. Capacities are up to 800 l/min.

Verder has chosen a wide variety in materials to offer solutions for the complete industry. We make a difference between housings in non-metallics and metallics.
Verderair are highly engineered diaphragm pumps, delivering a smooth, reliable flow at all circumstances. The new air valves design guarantees a perfect, non-stalling operation, even at low pressure and does not need any lubrication. Thanks to their unique design, they are able to handle very abrasive and / or viscous products.
The Verderair will run dry indefinitely without damage. Verder has selected those materials, which offer the best combination of benefits to the end user. The used wetted pump part materials are Acetal, Polypropylene, Kynar, Aluminium, Cast Iron and Stainless Steel. For ball and /or diaphragm, VERDER selected PTFE, Hytrel, Santoprene, Viton, BUNA-N, SS and Acetal.
NEW - Atex: Verderair offers now pumps in a conductive polypropylene housing. With this unique material you can benefit from the polypropylene-advantages in an Atex environment.
The flow range is from 0.1 up to 1,060 l/min and pressures up to 8 bar (or 16 bar for high-pressure models).

The double diaphragm system increases safety when sampling expensive or extremely hazardous gases. Should the primary diaphragm fail, the other diaphragm keeps the sample flow intact. The 1/8" NPT port connection allows the user to add a leak detection system and alarm. The detection system monitors the diaphragm for failure analysis and assures system integrity until maintenance can be performed.

Economical and robust, the Milroyal G pumps dose all traditional liquids used in water treatment and industrial processes including: acids, bases, chlorinated products, coagulants, and other products. Designed for ease of maintenance and start-up, the Milroyal G features a robust HPD-style hydraulically actuated diaphragm liquid end coupled to a variable eccentric drive. The absence of contour plates in this liquid end results in "straight-thru" flow ideal for handling polymers and slurries. A unique integral 3-function valve allows for purging of any entrapped gases in the hydraulic oil without disturbing the relief valve setting. Also integral to the liquid end is a site glass for visual indication of a relief condition in the hydraulic system. The smooth sinusoidal flow produced by the variable eccentric drive minimizes flow pulsations and mechanical shock to system components.
Product Features:
HPD liquid end design eliminates contour plates.
Double diaphragm w/leak detection available (10/98).
Liquid End Materials: PVC, PVDF, 316SS.
High viscosity and slurry liquid end options.
56C face and IEC motor options
Integral 3-function valve in hydraulic oil system: automatic airbleed, safety/relief valve, purge button.
Non-lost motion drive design minimizes flow pulsations and mechanical shock.
AC & DC variable speed drives available for automatic control from a 4 - 20 ma signal.
Recommended Service Intervals: 8000 hours when operating at full rated pressure
