AODD pumps have efficiency management

Metering pump with variable eccentric drive

Wilden’s Original Series Plastic air-operated double-diaphragm (AODD) pumps now feature the company’s Efficiency Management System (EMS), which makes the pumps work within the actual operation parameters regardless of the application demands or pump size.

Lewa has developed Ecosmart, a compact diaphragm metering pump range that it says offers the best price-performance ratio in its class due to its use of a variable eccentric drive. The different stroke frequencies of the drives makes it possible for the pumps to cope with a range of fluids and process requirements.

in the chemical industry, feeding of corrosion inhibitors, dosing of colorants and flavours in the food industry, additive metering in the plastics industry and chemical injection in the oil & gas industry. Individual configurations are optionally possible, such as offshore paint, material test certificates or testing according to API.

The pump is suitable for pressures up to 80 bar and flow rates up to 300 l/h at temperatures up to 120°C. The pumps feature suction pressuredown to 0.1 bar abs and feature threephase and AC motors standard drives according to IECand NEMA. Frequency control for speed adjustment is also possible. The design includes a PTFE sandwich diaphragm with diaphragm monitoring, a diaphragm protection system (DPS) and optimized check valves. An individually adjustable pressure relief valve prevents potential overload situations of the pump.

The EMS allows the operator to use an integrated control dial to select the efficiency point and flow rate that best suits the chemical transfer application.

The pumps include air distribution systems, diaphragm technology, and clamped wetted path designs, making them suitable for chemical transfer. They are available in two sizes, from the 38 mm (1 ½ in) PX4 and the 51 mm (2 in) PX8 models. Both models can handle pressures up to 8.6 bar (125 psi), while the PX4 features a flow rate of 363 lpm (96 gpm) and the PX8 a flow rate of 594 lpm (157 gpm). www.wildenpump.com

High pressure float for liquid level indication multi-spherical design that withstands pressures up to 3500 psi (241 bar) while delivering a highly focused magnetic field. A non-pressurized titanium design makes the floats safer than pressurized versions for applications where mid to high-pressures coupled with low product densities previously posed a challenge. The high pressure float withstands high pressures.

Clark-Reliance Corporation has developed a new high pressure float design for its liquid level indicators for use in Jerguson Magnicator II Magnetic Liquid Level gages. The float features a

The new float can accommodate specific gravities as low as 0.5 and temperatures up to 600°F (315°C). It features segmented designs to reduce ground clearance under the indicator column, making installation easier. www.clark-reliance.com

The Ecosmart complies with API 675 (American Petroleum Institute). The diaphragm metering pumps are suitable for water treatment in power plants, metering of additives in industrial water processing, pH adjustment, dosing of solvents

Diaphragm valve reduces energy consumption GF Piping Systems has developed the Type 514-519 high flow diaphragm valve series that it says provides significantly increased flow rate performance and lower energy consumption. This improves the valves’ suitability for applications where diaphragm valves were previously not considered due to flow restriction. The Type 514-519 features a new flow geometry design which provides Cv values double the traditional design with values ranging from 3.9 to 116.8, www.worldpumps.com

depending on size and end connection. This provides linear flow and control characteristics that improve processing stability, resulting in reduced operating costs and more cost-effective media transport. There is a self-draining feature to minimise dead space and improve hygiene and resistance to crystallizing fluids. This new design means that traditional metal bolts are not required to hold the valve together. Instead, the top-works are threaded directly onto the body, eliminating the need to re-torque the bolts

due to thermal expansion. There is a metal-free threaded bonnet connection, corrosive build-up is minimized in applications with highly aggressive media. The diaphragm valve series is available in PVC, CPVC, PP, PVDF, and ABS body materials in sizes 1/2-2 in (with larger sizes available in the 314-319 Series). Diaphragms are available in EPDM, PTFE, FPM and NBR. This material range covers practically the entire spectrum of chemicals with which the diaphragm valves can come

into contact, optimizing process compatibility. Standard PVC, CPVC, PP, and ABS versions handle pressures up to 150 PSI while PVDF versions handle pressures up to 240 PSI. The valves are suitable for contaminated media, media containing solids, and high purity liquids for a variety of applications such as chemical process industry to microelectronics, water treatment, cooling and control. www.gfpiping.com
