FLUIDS & LIQUIDS HANDLING in c. pumps & val ves New pump hoses for food applications with 80% greater life • Long life peristaltic pump hose promotes uptime and reduces maintenance • New food grade hose has a white inner lining and is FDA certified Watson-Marlow Pumps Group is introducing a new food grade hose for use with Bredel pumps. FDA and EC compliant, the new F-NBR hoses offer better wear resistance and longer life for improved production efficiency and process/ product safety. Any manufacturer in the food and beverage sector that is using peristaltic pumps to dose additives or transfer abrasive, shear sensitive and viscous substances, will know all about the need for process uptime. To better meet this perennial requirement, Bredel is launching its F-NBR food grade hose which meets FDA 21CFR177.2600, EC 1935/2004 and BfR XI cat.4 regulations and provides up to 80% longer life. Bredel hose pumps can deal with products as diverse as soft fruit and shell fish, abrasive yeast and finings, as well as fluids containing high concentrations of hard solids such as whole spices. Hygiene is seen as another key benefit - unlike other pumps which incorporate a variety of moving parts and can contribute to microbial growth and contamination, Bredel hose pumps have no direct contact with the product at any stage of the production process. The new F-NBR hose can be cleaned by clean-in-place and steam-in-place sterilisation at full velocity, without the need for a bypass. At a time when organisations are under particular pressure to contain costs, maintain and improve quality and limit the expense of downtime and lost production, the introduction of the new F-NBR hose is good news to food manufacturers. Available in size 10-100mm, F-NBR hoses are manufactured in accordance with cGMP guidelines. For more information contact Watson-Marlow Pumps Group, Falmouth, Cornwall.

RELIEF VALVE PREVENTS LOW PRESSURE DAMAGE TO EQUIPMENT Brownell Ltd has introduced a large range of pressure relief valves to prevent damaging pressure differentials in a wide range of industrial applications. Flow rate requirements from just 0.1 litre/min up to10,000 litres/ min depending on the applications and maximum allowable differential pressures. Pressure relief valves are used for preventing the pressures and vacuums that can be destructive or cause malfunctions in equipment containers, storage vessels and pressure sensitive instruments. In the event of increasing pressure due to system malfunction or environmental heating (or cooling), the relief valves will open at the set point and relieve the pressure of air or gas until a safe working level is achieved. The relief valves automatically reset when the re-seat level is reached and continue to maintain a safe working pressure. A typical valve application would be on cargo containers being transported by air. They can prevent an in flight hazard in the event of depressurisation or system malfunction.

Available in a wide range of wetted materials the M Pumps range is designed to handle liquids containing up to 20% entrained gas, as well as thin, non-lubricating liquids, or for pumping small flows at high differential pressures. The pumps can handle capacities up to 13m3  /hour at differential heads up to 164 metres for single stage designs and up to 500 metres for multistage pumps. Low NPSH versions are also available for refrigeration / cooling applications, or for pumping boiling liquids or high vapour pressure liquids, with an NPSHR down to 0.5 metres.  The key features and benefits of the M Series includes; a high-head, low-flow capability which minimises the need for bypass requirements, hydraulically and dynamically balanced impellers which are designed to handle liquids containing up to 20% entrained gas and a close-coupled design which eliminates alignment issues. They also have ability to handle liquids with a wide range of viscosities from less than1 cP up to 200 cP. M Pumps are available in polypropylene, PVDF and stainless steel liquid end construction.
