New seal-less pumps provide zero leakage
The new Moyno Mag Drive 500 Series pumps feature a patented sealless, magnetic drive design that provides zero leakage for critical applications. These pumps can handle toxic, aggressive, caustic, or even flammable and explosive fluids. This proprietary progressing cavity mag drive pump uses the latest technology to ensure operator safety, eliminate work place hazards, and protect the environment from contamination.
Product features and benefits include:
• No mechanical seals are used, eliminating costly repairs;
• Pulsation-free, low-shear pumping action, maintaining product integrity;
• No vapor locking when handling volatile liquids;
• Four models from which to choose for application versatility;
• Flow rates from 0.1 to 900 GPH;
• Composite housings and internals;
• Stator materials include Nitrile or EPDM with optional FPM stators and titanium rotors; and
• Skid-mounted, turnkey systems available.
Typical applications include pumping sodium hypochlorite, ammonia, hydrogen peroxide, ferric chloride, aluminum chloride, and other caustic fluids.
Mounting flange reduces costs
In response to the volatile price swings of the metal supply market, engineers John Williams and Vinh Nguyen designed a thermally compensated mounting flange. The driving objective for the new design was to reduce the cost of valves constructed with one of the most expensive metals used in a severe service valve — titanium.
For severe service at high temperatures, MOGAS Industries had been using a titanium flange to allow for equivalent thermal expansion since the same materials were used for the valve and flange. If
there were cost to be saved, without diminishing the integrity of the valve, it would be found in the mounting flange.
The two engineers designed a mounting flange constructed of 410 stainless steel with a precision cut in the flange. The cut allows the flange to grow and flex without causing damage to the valve, while maintaining precision alignment of the valve stem and actuator. The result is a cost savings for the customer without jeopardizing the valve or the facility using the valve.
The use of 410 stainless steel provides a cost savings of about 70% for the mounting flange.
