Seat valve for hygienic applications The new Small Single Seat Valve from Alfa Laval is available in ½" or ¾" sizes and has been designed to be used in pump or process systems in the pharmaceutical and food industries, indeed anywhere where hygiene is an important consideration. It can be used as a two- or threeport stop valve or as a
changeover valve with three to five ports. According to the manufacturers, the simple design has very few moving parts so will be reliable and consistent in stopping or diverting product flows. The valve is opened and closed via a PVDF plug that is lifted up or down and held in
Non-metallic magnetic drive pumps can contain aggressive chemicals Finish Thompson’s extended KC 3 series pumps can now deliver flow rates of up to 44 m3/hr and a maximum head of 32 m in chemically aggressive environments. The pump has a maximum fluid temperature capability of 104 °C and its magnetic drive configuration will ensure leak-free performance. The enhanced capabilities of the new plastic pump series has been combined with an extension in its versatility, with closed impeller and multistage units also now available. In addition, the latest generation of KC 3 series pumps can also be specified to conform with the EU’s ATEX directive for use in explosive environments.
The magnetic drive utilises neodymium rare earth magnets to ensure a compact design. Combined with carbon bushing and a ceramic spindle, this configuration provides end users with a run dry capability that can last for up to 24 hours claim the manufacturers. Polypropylene or PVDF housings can be specified with the centrifugal pump. According to the manufacturers both options offer good chemical and corrosion resistance.

The valve can operate with temperatures from -10 °C up to +140 °C and with pressures of up to 10 bar. It also meets the 3A and EHEDG standards for use in hygienic applications in the USA and in Europe.
Small scale dosing pump The compact QBG low current DC pump from Fluid Metering Inc (FMI) is designed for injection duties across a range of different industries. Typical end uses include dosing concentrated tracer dyes, water treatment chemicals and other additive fluids. The flow path is constructed of ceramic and fluorocarbon materials making it chemically inert and versatile enough for many different applications. The pump stroke rate can be adjusted by varying the voltage. A 12 VDC or 24 VDC unit can be utilised with the QBG. In addition, the stroke
length can be mechanically adjusted to suit end user requirements. The piston pump can dose from 4.8 ml/min up to 76.8 ml/min and has an operational pressure capability from 0.70 bar to 4.1 bar. According to the manufacturers, the QBG pump has an accuracy of +/-1% and can be used in remote applications with battery power. Dimensionally, the unit measures 246 mm in height, has a depth of 135 mm, and is 171 mm wide. The compact pump should, therefore, fit into most locations however cramped.
Typical end uses for the KC 3 series centrifugal pumps include metal treatment processes, chemical transfers, and effluent treatments.
The latest generation of KC 3 series pumps from Finish Thompson can resist chemical degradation and operate with fluid temperatures of up to 104 °C.
