Air/vacuum valve

The Air/Vacuum Valve from Larox Flowsys automatically exhausts large volumes of air from the system while it is being filled with slurry. When the contamination is being emptied, air displaces the fluid and re-enters the pipeline to equalize pressure. It prevents discharge of the medium to keep your work environment clean and safe. When the system is filled and operating, the fluid lifts the ball until it closes the orifice.

Hi-Tech spiral blade clarifiers offer the optimum in sludge removal and effluent quality. The spiral design moves sludge to the hopper more effectively than a standard scraper style clarifier mechanism. The clarifiers can be fitted with an energy control well and/or a density current baffling system. All features combined help to promote fast settling, quick sludge removal and an overall better effluent. Each clarifier or thickener uses a Hi-Tech cast iron or fabricated steel drive unit, with mechanical or hydraulic overloads.

Remote monitoring

Pennwell web 300 230

The Aquavx Scout RTU is the gateway to the company’s Advanced Remote Monitoring service. The new panel mounted RTU offers full functionality in a compact package with 10 digital/discrete/pulse inputs, four analog inputs, two relay outputs, and MODBUS RTU support over its RS485/RS232 port. Users can receive real-time alarms via SMS, email, or automated voice telephone call, volumetric flow calculation, historical data, trending, and reporting for less than they would typically pay for a traditional landline based dialer.


Pennwell web 45 150Odor, corrosion control

The Vortex Flow Insert from IPEX is designed to eliminate odorous emissions and minimize corrosion in vertical sewer drops. With no moving parts and requiring virtually no maintenance, the inserts have delivered significant cost savings in monthly chemical feed, air-phase treatment and maintenance costs.


Cake pump

Pennwell web 225 300

The seepex Cake Pump System includes a BTHE cake pump designed to allow flow rates up to 220 gpm at differential pressures of 540 psi. The system includes an auger which pushes the cake into the pumping element. The pitch, diameter and speed of the auger can be adjusted to match the application.

Emergency actuators

Pennwell web 200 300

Robo-Control manufactures battery-operated actuators to remotely open and close hazardous gas cylinder and container valves such as chlorine and sulfur dioxide. The actuators weigh as little as six pounds and mount to the valve independently from existing hardware or dispensers. Each actuator has integral indication for actual valve position and outputs for valve position are available. Some actuators can communicate with an RTU or PLC for SCADA or in-plant control.
