UK specialist pump manufacturer Flotronic Pumps Limited was founded by Lew Norris in 1981. The engineering design consultancy ‘Norris Brothers’ had been involved in the design of specialist pumps since 1952. Lew Norris’ new company pioneered the air-operated, double-diaphragm ‘One-Nut’ pump. Flotronic’s ‘One-Nut’ design allows quick pump disassembly for inspection, cleaning and maintenance – delivering a massive benefit for pump users in terms of reduced down-time, particularly as the pump can be inspected or maintained in line without disconnection of pipework. Flotronic remains the only British-owned specialist manufacturer of air-operated, double-diaphragm pumps in the UK.

The Neptune Series MP7000 has been engineered from the ground up to be more robust and durable than similar mechanical diaphragm pump designs. The Series MP7000 pump incorporates the ruggedness of a hydraulic diaphragm metering pump, eliminates the need for intermediate fluid or hydraulic oil to actuate the diaphragm and reduces the potential for gearbox oil to contaminate the process. Series MP7000 pumps also feature a finned gearbox that dissipates the heat created during normal operation more readily than other designs, oversized check valves that improve performance and minimize friction losses, and rugged bronze gears for quite-running and long service life. Additionally, the straight-through flow design of the Series MP7000 liquid end and the elimination of the contour plate results in improved flow characteristics, making the pump the ideal solution for pumping difficult chemicals such as viscous fluids, shear-sensitive fluids and fluids with suspended solids.
The new Series MP7100 is a mechanically actuated diaphragm metering pump. The MP7100 pump incorporates the ruggedness of a hydraulic diaphragm metering pump, eliminates the need for intermediate fluid or hydraulic oil to actuate the diaphragm and reduces the potential for gearbox oil to contaminate the process. The result is a pump design that provides accurate dosing of a wide range of mild to aggressive chemicals, including those used in municipal water and wastewater treatment.
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.
Pure-Fuse diaphragm technology incorporates a one-piece design that eliminates product-trap areas between the outer piston and diaphragm that can harbor bacteria, a critical consideration for hygienic applications. This patented design also provides an unbroken fluid-contact surface for CIP capability and reduced contamination risks. Pure-Fuse combines food-grade plastics and elastomers with a stainless-steel core using no adhesives or nylon fabric that can contaminate process fluids in the event of a breech. In addition, by eliminating the outer piston Pure-Fuse diaphragms experience reduced abrasion, which results in longer diaphragm life.
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.
All parameters of the modular eccentric diaphragm pump series EC-L 500 can be customized exactly to individual requirements. The pump heads are manufactured from highly resistant PPS. A wide variety of materials is available among the elastomers (EPDM, FKM, FFKM, silicon, PTFE, etc.) – depending on the intended purpose.
The options for motors lats from the economically prized standard drive to extremely long-lasting brushless motors and on to stepping motors with high-precision metering function.
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.
Flotronic Pumps Limited, the UK-based specialist manufacturer of air-operated double diaphragm pumps, having already secured 3-A Sanitary Standards, Inc (3-A SSI) approval for their ‘H’ series pump, have now achieved the European Hygienic Engineering & Design Group (EHEDG) accreditation for their new ‘E’ Series pump.
The ‘E’ Series pump has been specifically designed for the Food and Beverage industry and other processes where product contamination must be avoided. The pump’s features include Flotronic’s established and unique ‘One-Nut’ pump design which allows swift diaphragm access without disconnecting process pipework. The internal surfaces of the ‘E’ Series pump can be effectively ‘cleaned in place’ or, alternatively, easy dismantling can be carried out for cleaning and inspection. Cleaning is aided by the provision of polished wetted surfaces to 0.8μm Ra maximum and an electro-polished overall finish. Cleanability is also assisted by the incorporation of a support stand whereby the pump can be inverted for full draining.
