Model: Inlet Vibration Isolation Pump Drops
Includes flow control, vibration-controlling flexible couplings, access ports for gauges and thermowells, and an integral flanged pump connection Class 150 flange connection; Provided with a suction diffuser Application : This Suction Vibration Isolation Pump Drop connects the water flow intake to the pump in the mechanical room.Provides noise reduction, expansion, contraction and deflection.The following charts show the relative vibration attenuation characteristics of the Series 381/381G Suction Vibration Isolation Pump Drop compared to double sphere rubber connectors and stainless steel braided pump connectors, respectively, for typical HVAC pump speeds. For all sizes shown, the vibration attenuation provided by the Series 381/381G exceeds the vibration attenuation characteristics of the other products tested, for typical HVAC pump speeds. Additionally, the Series 381/381G provides linear movement and angular deflection capabilities,along with the ability to accommodate piping misalignment, which should reduce stresses at pump or equipment connections. The use of either cut grooved or roll grooved pipe offers the same vibration attenuation characteristics.Standard weight carbon steel conforming to ASTM A53 Grade B.
