The 34 Series™ internal gear pump is the perfect solution for asphalt, bitumen, tar, and more due to its robust cast iron construction and jacketing to rapidly deliver heat. It can handle flows up to 450 GPM (102 m³/h).
Features & Benefits
- Fully jacketed pump to rapidly deliver heat directly to the stuffing box, casing and head
- Jacketing suitable for hot oil or steam for enhanced application flexibility
- Simple, economical design for transfer and delivery of asphalt and bitumen at low to moderate pressures

Clean asphalt contains no fillers and is an oil based liquid. It is primarily used in paving roads, waterproofing liquids, and paints. Typically they are handled at elevated temperatures to reduce the viscosity of the asphalt. The pump needs a source of heat like jacketing or electric heat to prevent the product from solidifying in the pump.
- Cast iron
- Leak prevention with O-Pro® Cartridge seal
- Capacities to 280 GPM
- Jacketed for steam/oil heating prior to pump startup
Emulsions are asphalt suspended in a mixture with water or other liquids. This is done to ease the application of the asphalt. Uses would be crack filling, coating roadways, or waterproofing. These emulsions are shear sensitive and must be handled with care.
- Cast iron
- Jacketed for steam/oil heating prior to startup
- Mechanical seal options
- Capacities to 500 GPM
Filled asphalts contain particulate used in the liquids’ end applications. Examples of this would be roofing materials and hot mix plants. Typically they are handled at elevated temperatures to reduce the viscosity of the asphalt mixture. The pump needs a source of heat like jacketing or electric heat to prevent the product from solidifying in the pump.
Is the liquid that remains after the distillation of coal tar or refining of petroleum. It is used in paints, roofing and paving materials. It is also used in the production of anodes for aluminum smelting and graphite electrodes in steel production.
