NRV Worm Gearbox for Sampling and Gate Valve Actuators

NRV Worm Gearbox for Sampling and Gate Valve Actuators Sampling points and gate valves across a treatment plant’s process flow need actuators that hold a precise, repeatable position — a sampling valve that drifts compromises the accuracy of monitoring...

NRV Worm Gearbox for Small-to-Medium Sludge Scraper Drives

NRV Worm Gearbox for Small-to-Medium Sludge Scraper Drives Sludge scraper mechanisms move settled solids toward a collection point in settling tanks and small clarifiers, running at very low speed under continuous duty for years at a stretch. On the smaller scale...

NMRV Worm Gearbox for Small-Tank Mixer Drives

NMRV Worm Gearbox for Small-Tank Mixer Drives Small process tanks across a treatment facility — chemical preparation tanks, sample mixing vessels, polymer make-up tanks — need consistent agitation without the scale or cost of the large mixer drives specified for...

NMRV Worm Gearbox for Chemical Dosing Pump Drives

NMRV Worm Gearbox for Chemical Dosing Pump Drives Chemical dosing accuracy in water and wastewater treatment depends on metering pump drive precision — over-dose and you waste chemical and risk process upset; under-dose and treatment effectiveness suffers. The...

NRV Worm Gearbox for Inlet Screen and Grille Actuators

NRV Worm Gearbox for Inlet Screen and Grille Actuators The inlet screen at a wastewater treatment works is the first mechanical barrier between raw influent and the rest of the plant — its raking and grille positioning mechanisms need to operate reliably in one...
