Pump spill prevention

The patented Blacoh Spill-Stop® is designed to prevent chemical spills caused by the failure of diaphragms in air operated diaphragm pumps. It's patented design captures any contaminated exhaust air or liquid leaked through a ruptured diaphragm. A float-controlled valve shuts off the compressed air supply to the pump, insuring no further liquid is pumped through the failed diaphragm. The valve can automatically turn on a standby pump or trigger an alarm for immediate response.

Priming valve

LMI Milton Roy has developed a new accessory for its metering pumps that allows for the constant removal of vapors and gases in sodium hypochlorite and hydrogen peroxide applications. The new AutoPrime Valve primes automatically and functions as an air-gap, anti-siphon valve. Pump output is regulated by venting the discharge to atmosphere during each stroke, eliminating the need for a back-pressure device. In addition, it provides a vertical discharge, traditional in pump applications. The unit offers a flow range of .08 to 5.0 milliliters per stroke with a maximum pump output of eight gallons per hour. Stroke rates are five to 100 per minute with a stroke length of 30% to 100%.

Fail-safe actuators

Rotork has introduced the Skilmatic™ line of electric fail-safe linear and quarter-turn actuators. The line includes modulating, isolating, emergency shutdown (ESD), and spring-return models. The actuators are specifically designed to provide a solution for automatically positioning a wide range of valves or dampers in a safe condition on loss of power and modulating control with a resolution of <0.25%. The actuators are compact, self-contained units that have a minimal number of moving parts. They incorporate electrical operation with precise hydraulic control and spring-powered fail-safe action. They operate from a standard 230/110V AC supply and are energy efficient. The internal spring-return mechanism can be configured to close, open, or lock in position in the event of a power or system failure.

Submersible sensor

Instrumentation Northwest has introduced the AquiStar® PT2X Smart Sensor with built-in datalogging. Measuring pressure, temperature and time, this industry standard digital interface device records more than 500,000 datapoints in non-volatile memory and operates on low power. The unit is programmed using a laptop or desktop computer via its RS232 connector, a RS485/RS232 adapter and INW's Aqua4 software. Once programmed, the unit will measure and collect data at a variety of time intervals. Units can be used to monitor groundwater, well, tank and tidal levels, as well as for pump testing and flow monitoring.
