Crane Chempharma Flow Solutions presented several new products at the Achema 2009 exhibition and conference.
For example, it showcased the DEPA E4 Compound Diaphragm.
This is an air-operated diaphragm pump that features a 'noppedE4' surface, which refers to a uniform sequence of small mounds radiating in a band located medially within the diaphragm, giving excellent flexibility.
It is available in four sizes, ranging from 0.5 - 2in (12.7 - 50.8mm).
It is made from PTFE and EDPM, coming into contact with liquid and air respectively.
The outer piston is entirely encapsulated.
DEPA E4 offers: increased life span, improved safety, increased efficiency and an ultra-clean working mechanism.
The increased flexibility enables greater flow rates and reduced air consumption, resulting in energy savings.
The diaphragm's single-unit construction allows easy installation and replacement.
The laminated design of the DEPA E4 Compound Diaphragm increases its impermeability.
This improves safety, as does the ultra-clean working mechanism, which prevents leaks/deposits and limits areas for bacteria build-up.
The high chemical resistance is maintained right through the entire pH range (0-14) against most media.
EDPM is electrically conductive, which makes it suitable for use in ATEX-conforming pumps.
The diaphragm is approved for use in Zone One when used in conjunction with pumps made of stainless-steel casting.
The new DEPA E4 Compound Diaphragm is compliant with CE markings.
The Cirrus Resistopure HP is a hose that is suitable for use in biotechnology, pharmaceutical, food and drink and cosmetics industries.
The hose is equipped with a revolutionary PTFE lining (replacing the former FEP lining) that endows the hose with a longer flex life and greater chemical resistance.
Its new construction allows for an improved bend radius with full vacuum rating at elevated temperatures.
The liner itself is now thicker, while the hose retains the same flexibility, yet offers greater resistance against permeation.
The Cirrus HP Resistopure hose is available in a range of sizes (ranging from 0.5 - 2in) and comes with several fittings options.
The hose is designed for pharmaceutical processes and utilities, biotechnology processes, CIP (clean in place) and SIP (steam in place).
The Stratus is a Teflon PTFE-lined silicone hose that can minimise the risk of potential contamination in pharmaceutical and biopharmaceutical processing, utilities and cleaning applications.
The hybrid hose's natural smooth-bore Teflon PTFE liner is flared through a platinum-cured stainless-steel wire and fabric-reinforced silicone shell.
The Stratus hose combines the benefits of Teflon with those of silicone, including light weight and flexibility.
The Xomox XLD series of fluoropolymer-lined process butterfly valves has DIN/ISO mounting capability.
The XLD's one-piece seamless body-liner and resilient FKM body-seal ring provide reliable and low-maintenance operation.
The liner encloses the lower end of the shaft, preventing a potential leak path, thereby rendering additional external seals unnecessary.
The body liner extends up the shaft bore to above the secondary seal (triple FKM O-ring).
A remarkable feature of its design is the one-piece valve disc.
The metal core (disc/shaft) uses a single-unit design lined with a non-porous fluoroplastic extending above the secondary seal.
This enables the process butterfly valve to create a high-integrity atmospheric seal.
The XLD butterfly valve features an API 608-compliant device that prevents potential blow-out of the shaft.
The XOMOX Lined Ball Valve (XLB) has a steam-sealing system that provides safety and long-term fugitive emission-control under extreme conditions.
Its dynamic body joint design allows the valve to retain pressure boundary during thermal cycles.
Lower torque reduces actuation costs and saves space.
The Saunders Exelon XA diaphragm features a diaphragm material based on ethylene propylene (EP) technology, for handling chemically aggressive slurries.
The diaphragm is 100 per cent compatible with all existing IDV Saunders product ranges and is available for new installations and for diaphragm replacements in existing Saunders valves.
Exelon XA diaphragms enhance flex life; improve elastic recovery by 70 per cent, resulting in better sealing performance and reduced emissions; and maximise rebound resilience, improving erosion resistance while maintaining the same high level of chemical resistance as previous Saunders EP and butyl-based diaphragms.
This means the diaphragm lasts longer in processing slurries and improves performance for minerals and materials applications.
