FLUIDS & LIQUIDS HANDLING in c. pumps & val ves HYDRA-CELL MONOBLOCK PUMPS EASE INSTALLATION & SERVICE Wanner  International has introduced an optional Mono-Block style pump head on its Hydra-Cell G03, G13 and P200 seal-less pump models. The new Mono-Block pump head combines the traditional valve plate and manifold into a single component, allowing easy access to the cartridge style valve assemblies. The valves are accessed easily without the need to disassemble the pump or disturb the system pipework. Routine maintenance, valve inspection and, if necessary, replacement, can be carried out quickly and efficiently and causes very little downtime while cutting service and maintenance costs. A further benefit of the Hydra-Cell with Mono-Block pump head is its ability to prime quickly at slow speeds. Mono-Block pump heads are available in brass or 316 stainless steel. Diaphragms are available in a range of materials from PTFE and Viton to Buna, Neoprene and EPDM, to suit the requirements of the liquid being pumped. The Mono-Block pump head is reported to be a further improvement to the design superiority and operational excellence of Hydra-Cell pumps.

Control valve specialists SAMSON CONTROLS offer a range of products incorporating these features which are manufactured to quality assurance systems certified to ISO 9001, whilst also meeting stringent FDA requirements. For example, their type 3347 control valve has polished steel parts to ensure the highest purity for the process medium, special PTFE bushing along with an additional steam line connection that is used to meet very stringent purity requirements preventing bacteria from spreading at the actuator stem guide. Another example is the Type 3249 valve which is equipped with an EPDM diaphragm and a back-up safety packing box to ensure total protection against bacteria spreading and prevent product leakage. These sealing systems, which constitute the main components of the valve construction, have been thoroughly developed and designed to ensure a long and reliable service life. Process applications which involve pasty, fibrous or highly viscous products are best controlled by Samson’s Type 3345 cavity-free valve body which features a diaphragm available in either rubber, nitrile, butyl or PTFE which acts both as a seal and a valve plug. These valves can be easily installed into the process line as they are available with various connections including hygienic couplings, flanges and clamp connections according to ISO 2852 and welding ends.
