Gorman-Rupp’s sound-attenuated enclosures available from Hydro Innovations offer a protective and efficient way to diffuse unwanted sound. The silent pump units have all the features and benefits of the self-priming pump line, including external shimless wearplate adjustment, removable coverplate with easy grip handle and a removable rotating assembly.
All silent pump units ship standard with a discharge check valve. Lockable doors on the silent pump units prevent unauthorized personnel from tampering with the pump, fuel, engine or controls during unattended service, and fuel capacity allows for a minimum of 24 hours of continuous operation.
All silent pump units feature a lightweight, corrosion-resistant aluminium enclosure that is acoustically treated to maintain noise levels as low as 63 dBa while operating at full load and environmentally engineered to operate much quieter than current industry standards.
