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.

As a replacement to conventional submersible pumps, the manufacturer Hermetic supplied two 8-stage, sealless canned motor pumps. The distinctive feature of the transformation was the customized adaptation of the pumps to the existing plant and its vessels. The pumps were designed for easy installation in the existing tank (with a diameter of 500 mm). The customer, a Swiss fine chemicals manufacturer, thus saves the costly, time-consuming conversion of the existing systems in its production plant.
Over the past years Wanhua Chemical Group, the world’s largest producer of MDI (Methylene diphenyl diisocyanate) has been experiencing rapid domestic and global growth. As one of Wanhua’s top suppliers for critical equipment for more than 10 years, Richter’s global presence has contributed to the expansion of Wanhua with pumps and valves for the most corrosive applications. Reliable quality and top notch service have been key to our long standing cooperation.
Chemtech World Expo – February 14-17, 2017 – is one of the largest events for the chemical industry. 600 exhibitors from 20 countries expect up to 40,000 visitors. At the same time eight international conferences and about 150 speakers are offered. In the German pavilion, the German community stand, organized by the VDMA, the company Bungartz will present the concepts of its problem-solver pumps at stand C6A, which also have a high intrinsic safety:
- Wear and corrosion resistant pumps for the fertilizer industry
- Pumps with hydrodynamic shaft seal
- Continuously dry running magnetic driven pumps for liquids with large solids contents
- Cavitation-free pumps with an NPSH value <0.1m
The target application for this positive displacement quaternary diaphragm pump series is the continuous dosing of high-value additives in the food and beverage and personal care industries (e.g. to add concentrates to a fluid stream for soft drinks) as well as for in-line dilution. These ‘QuattroTec’ called pumps can provide a consistent flow that results in a constant and continuous dosing of ingredients in hygienic processes.
The new CombiTherm Plus pump provides transfer of hot fluids without the need for additional, external cooling systems. The pump is available in two configurations suitable for the pumping of hot oil or hot water and provides an highly efficient and pumping solution. The air-cooled CombiTherm Plus pump provides transfer of hot oil or hot water in a wide range of applications including
- injection molding,
- chemical processing,
- asphalt / bitumen and tar processing,
- deep frying systems,
- steam generators,
- fuel heaters and
- heat recovery systems.
The pump keeps fluid temperatures uniform to ensure processes are efficient while its design protects seal faces and bearings from the heat of the fluid; ensuring durable, low maintenance, long life operation.
The actually supplied two canned motor pumps, with “tandem” design, convey the medium [C3 fraction with propylene as main constituent] at a temperature of 22 °C. The differential head [H] is 379 m at a flow rate [Q] of 7.8 m³/h. The pump units are designed for a nominal pressure of 40 bar and have temperature- and level-monitoring features. For online monitoring of the hydraulic axial bearing, a rotor-position monitoring feature is also provided.
The special tandem design of the multistage pumps results in minimal shaft deflection and load relief at the slide bearings. The “ZART” (Zero Axial and Radial Thrust) technology ensures a contact- and wear-free running of the rotor unit.
The pump casing of Fristam FDS pumps comes in three parts, consisting of an intermediate flange, the screw casing and the pump cover. This enables individual adaptation of the connections to any conceivable production system requirement. Thanks to central positioning of the gearwheels inside the bearing support area, the entire pump comes in a very compact design. Moreover, its massive shaft has reinforcements in the area of critical diameters to ensure maximum rigidity. Further stability is achieved through a combination of particular large bearings and an increased bearing distance. The result is smooth running with minimal wear.
The Sundyne LMV-803Lr is an API 610 compliant pump available in either OH3 or OH5 motor mounting configuration that provides ultra-low NPSHr performance – approximately 5 ft (1.5 m), across the entire performance range – for flows to 800 GPM (180 m³ / hr) and heads to 1,000 ft (305 m).
The ultra-low NPSHr allows the pump to be installed at grade level, eliminating the expense of installation in a pit and performing maintenance in a confined space. The vertical design is ideal for use in refineries, NGL, petrochemical and chemical plants, as well as handling light hydrocarbon handling services, such as bottom pumps for de-ethanizers.
The superior efficiency of the LKH Prime results in reduced energy consumption. This delivers low cost of owner-ship. Designed for CIP duties containing entrained air, it can also pump product, potentially reducing the capital investment when designing process systems.
Quiet in operation, the LKH Prime is engineered to meet the most stringent standards and hygienic requirements of the food, dairy, beverage, and home & personal care industries. The pump is also going to be available as an UltraPure model, meeting the needs of pharmaceutical customers.
