Screw Pumps Reduce Contamination
The Varodry oil-free, air-cooled screw pumps are easy to install and operate, and with few components, they require minimal maintenance. They operate with minimal noise and emission-free venting. Because they run dry and clean, there is no risk of oil leakage or oil migration into the vacuum chamber or into products or processes. Two models are available, the VD 65 and the VD 100, which have maximum capacities of 65 m3/hr and 100 m3/hr, respectively. The motor operates between 0°C and 40°C with a power rating of 1.5 kW for the VD 65 model and 2.2 kW for the VD 100 model. The pumps can be run in industrial environments, including moist and dusty areas, and do not require cooling water or compressed air. They offer uninterrupted operation with no downtime, and the small design is easy to retrofit and integrate into existing systems. The pumps are resistant to process media and are certified to International Protection class IP55.
Diaphragm Pump Is Available in New Materials
Hydracell T100 series high-pressure pumps are now available with corrosion-resistant Type 316L stainless steel pump heads and an expanded choice of materials, including fluoroelastomers and ethylene propylene diene monomer (EPDM) rubber for the diaphragm, and tungsten carbide, stainless steel, and nickel alloy for the valve components. The triplex pumps feature sealless diaphragms that eliminate hazardous volatile organic compound (VOC) emissions. They can operate with a closed or blocked suction line, and can run dry virtually indefinitely without damage, reducing downtime and repair costs. The diaphragm is able to handle abrasives with less wear than gear, screw, or plunger pumps. A rugged construction requires minimal maintenance, and the compact design with a double-ended shaft provides a variety of installation options. The discharge pressure can reach 5000 psi (345 bar) at up to 26 gpm (98 L/min). The pumps can replace horizontal centrifugal pumps and packed plunger pumps in oil and gas applications such as salt-water disposal (SWD), salt water injection, bulk transfer, and hydraulic lift in oil fields, as well as steam generation, reverse osmosis in water and wastewater treatment, and mine dewatering.

Optical Sensor Detects Errors
The Memosens COS81D hygienic optical sensor measures dissolved oxygen, gaseous oxygen, and temperature, with accuracy up to ±0.2%, in fermenters and bioreactors in the food, pharmaceutical, and biotechnology industries, as well in drinking water and boiler feedwater applications. The sensor has a low sampling volume, making it well suited for residual oxygen measurement and taking measurements in still, no-flow environments. It works in process temperatures from 15°F to 280°F and pressures from 0 psi to 190 psi. The housing is stainless steel with a 12 mm-dia. and is available in 120-mm, 225-mm, 360-mm, and 420-mm lengths. Two caps, which reduce blockages and the adherence of air bubbles, are available with the sensor: a C-shaped cap for measurements in liquids and a U-shaped cap for gas measurements. The sensor connects to a transmitter via a cable for continuous optical digital signal monitoring. Setup and calibration are simple and do not require polarization time. Integrated electronics store calibration data and other information, such as total hours of operation and operating hours under extreme measuring conditions. Once the sensor is connected, the data are transferred automatically to the transmitter via a noncontact connection. Because the sensor stores the data, it can be calibrated and adjusted independent of the measuring point. The transmitter generates an automatic error message if the sensor fails, or if the connection between sensor and transmitter is interrupted. The transmitter detects implausibly high or low measured values, irregular values due to incorrect measured values, and sensor cap aging. When errors are detected, the transmitter displays a warning and generates an error message. The sensor meets European Hygienic Engineering and Design Group (EHEDG) Type EL Class I and ASME BPE (bioprocessing equipment) hygienic requirements. It also has a compliance certificate for biological reactivity tests, as per USP (United States Pharmacopeia) Part 87 and Part 88 Class VI, for batch traceability of materials in contact with product.
Portable Air Quality Monitor Measures Multiple Gases

Highly responsive sensors allow it to quickly alert workers to dangerous gas hazards. The system is housed in a rugged NEMA 4X stainless-steel enclosure, so it is suitable for areas with high humidity levels and those that are prone to flooding. It meets the requirements of the NFPA 820 Fire Protection in Wastewater Treatment Plants, OSHA 29 CFR Part 1910.146 Permit-Required Confined Space, and ANSI 2117.1 Safety Requirements for Working in Tanks and Other Confined Spaces standards, and can also be used in environments with combustible petrochemical vapors. It is portable and has additional mounting feet and a handle, and it features a Modbus remote terminal unit (RTU) output that has an option for remote-mounted human-machine interface (HMI) display. Electrochemical cell sensors detect oxygen and hydrogen sulfide levels, and infrared (IR) sensors detect combustible gases. Local alarms, for which high and low limits can be set, display as red LED indicators on the detectors themselves. The system’s enclosure has a built-in 95-db buzzer and red strobe lights to alert workers farther away or in adjacent areas. The entire system can be integrated within a plantwide automated control safety system.
