Gorman-Rupp Widebase submersible dewatering pumps tackle the big jobs. Where large solids are not a problem, these versatile models offer high-head, high-volume operation and stand up to the abuses of the worst conditions. Whatever the application - general construction, strip mining, tunnel work or general purpose - Gorman-Rupp Widebase pumps are built to operate quietly, effectively and safely.
Note: Control panel included.
Disclaimer: Please call 1-800-333-3331 for detailed information concerning your model. Parts lists can sometimes vary from pump to pump. Your serial number is critical in determining the correct parts and service requirements for your pump. Information on this page is provided for reference only.
Warning: Do not use in explosive atmosphere or pump volatile flammable liquids.
Features
- High Head, High Volume Solutions: Gorman-Rupp Wide Base Submersibles are designed for applications where high volume and high head are required, and large solids are not a problem - Pumps have only two moving parts and three wearing surfaces so maintenance and repairs are minimal
- Abrasive Handling Impeller: Abrasion-resistant ductile iron and manganese bronze impellers stand up to sand, gravel and other abrasive materials - The fully shrouded impeller back reduces seal pressure and helps prevent foreign material from entering the seal cavity - Seal life is extended and operational life of the pump is increased. Optional impellers of CD4mCu are available for corrosive/abrasive applications
- Dual Seals, Double Protection: Primary seal keeps dirty water in the pump end and prevents contamination of the oil cavity - A second "fail safe" seal provides extra protection against the possibility of damage to the motor - Positive oil lubrication enables the pump to run dry without seal damage
- Corrosion-Resistant Stainless Hardware: Rotor shaft and all internal nuts and bolts coming in contact with the liquid are made of stainless steel to resist corrosion and pitting and extend the operational life of the pump - For severely corrosive/abrasive applications, stainless steel lifted pump models of CD4MCu are available
