Progressive cavity pumps
Metal stators are now available for seepex progressive cavity pumps. The stators are made with a procedure that uses "EDM" technology. A double-helix carbon electrode is machined and then passed through a "gun-drilled" section of metal bar stock, while very high electric currents are applied to the electrode. This type of technology has been used by seepex over the last 10 years to manufacture its Tricam® rotors.

Check valve
Red Valve's Waterflex™ Check Valve, for potable water applications, operates solely on line pressure and backpressure, no outside energy source is required. Forward hydraulic pressure folds the elastomer disk away from the perforated plate to allow flow. Reverse pressure seals the elastomer disk against the perforated plate to prevent backflow. The Waterflex has no moving parts, such as hinges or springs, which require maintenance or repair.
