Diagnostic Monitoring Systems utilize two diagnostic couplings with quick disconnect electrical connectors. One coupling is used for monitoring switch actuation on the motor operated valve. The other is for measuring three-phase power to an AC motor on the valve. These couplings are connected in-line with the quick disconnect connectors and allows the user to perform a test without having to remove the limit switch cover from the actuator. These couplings reduce testing time for conventional valve monitoring systems.
Diagonally split casing pump is suitable for boiler feed services as well as hot or volatile liquid applications requiring low NPSH characteristics. The diagonally split case feature allows both suction and discharge to be in the bottom half of the casing but above the centerline of the pump. Dynamically balanced impellers are keyed to shaft and secured by adjustable shaft sleeves. The diagonal split case pumps are flexible coupled to a standard horizontal drip-proof, totally enclosed or explosion-proof motor.
