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.

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 jaw geometry of the Rotex Non-Sparking consists of a conductive high-tenacity plastic that is injected onto the hub body which continues to be made of steel or other metals such as aluminium. The newly developed synthetic material prevents any static charging and is also designed to be so hardwearing that even in cases of elastomer wear out, torque will still be transmitted without any danger of sparking. As a result, maintenance work can be postponed to a convenient time frame. The failsafe and maintenance-free Rotex Non-Sparking is certified under EU directive 94/9/EC (ATEX 95) and thus deemed suitable for the use in explosive atmospheres.
In all processes for steel degassing under vacuum gases and vapors are formed that might be dangerous. Essentially CO and H2 as well as the vapors of volatile metals are released from the steel surface. Explosion protection in vacuum plants especially those that generate a large quantity of CO by the use of oxygen for decarburization so far has been assured by overpressure flaps at the metallurgical reaction vessels, alarm devices for water leakage, sensors for pressure and temperature as well as emergency venting with nitrogen. With the introduction of mechanical vacuum pumps efficient installations for gas cooling and dust separation became necessary.
Mouvex A Series eccentric disc pumps are now available in ductile iron construction – a critical upgrade as more companies in the oil & gas industry are integrating ductile iron systems into their processes. Additional upgrades to Mouvex’s A Series pumps includes the implementation of ISO PN16/ANSI 150 flanges while offering both Mouvex or standardized mechanical seals, which helps expedite installations regardless of location. A Series pumps also doubled its maximum differential pressure from 5 bar (72 psi) to 10 bar (145 psi), enabling it to be used in the safe transfer of viscous, non-lubricating, volatile or delicate fluids in a variety of oil & gas applications.
The new Tapflo pump series is certified by EHEDG, the European Hygienic Engineering Design Group. The aseptic pump series will come in three sizes. The first to be launched is the smallest, with a maximum flow of 425 litres per minute.
Isocyanates require a pump that handles product gently (low shearing), has strong suction capability, and offers a low-maintenance wear-compensation design. The SLC Series Eccentric Disc Pump features superior suction at low speeds, ensuring minimum product is left in the piping prior to maintenance. The design of the SLC Series allows the pump to self-compensate for mechanical wear, giving the eccentric disc pump the ability to maintain consistent flow rates over time.
