Gorman-Rupp 80 Series® pumps are designed for non-stop workloads. The straight-in-suction design of these high-efficiency pumps guarantees quick, positive self-priming and allows them to operate at high suction levels than most other self-priming centrifugal pumps. Liquid enters directly into the impeller eye. A suction check valve presents in-line return flow when the pump is shut off. and, because 80 series pumps have few moving parts, maintenance is minimal. 80 Series pumps are available with self-lubricated mechanical shaft seals.
O Series® pumps have a straight-in suction design (there is no check valve) which eliminates entrance restrictions and provides better suction performance when handling solvents and similar liquids. O Series pumps can be used as transfer pumps, clean water supply pumps, on spray applications and many other industrial uses. They provide reliable performance with few moving parts and offer savings in maintenance and efficiency. O Series pumps are available pedestal mounted for flex coupling or v-belt coupling to a power source (not available for petroleum applications) or close coupled to electric motors. Powertake-off models are also available with helical gear increasers for heads up to
400 feet (121 meters).
Roto Prime® self-priming centrifugal pumps are specifically designed for pumping petroleum products, petrochemicals and solvents. They are available as straight centrifugal pumps or with the exclusive Roto Prime design. This design incorporates a variable capacity vane pump that quickly and automatically evacuates air and vapor, making them ideal for off loading transports and stripping hoses.
Gorman-Rupp Shield-A-Spark self-priming centrifugal pumps are the safest approach to handling flammable liquids with an engine driven pump. Pump volute and intermediate are constructed of lightweight aluminum. Steel wearplates are replaceable. Mechanical shaft seals have carbon and Ni-resist wearing surfaces. Elastomers are Viton®. Gasoline engine unit features dependable, rugged military or aircraft type spark plug which is radio suppressed and prevents spark gap jumping. Shielded ignition wire provides enclosed path for high tension spark. Sealed toggle ignition switch is safe, spark free. Sparkarresting muffler is designed to retard both spark and flame.
Gorman-Rupp's Unit 608 Tankleenor provides quick, efficient and economical cleaning of below-ground petroleum storage tanks. Even when tanks are thought to be free of moisture and debris, they often contain enough water and other contaminants to degrade the stored product. Tankleenor can remove contaminants like gel precipitates, microbial growths, rust and water without disturbing the product or taking the tank out of service.
