This self-priming, external spur gear pump has 1-inch port and will deliver flows up to 22 gpm. Maximum rated differential pressures for the pump is 100 psi. Designed for simplified maintenance, the pump may be quickly disassembled without the need to break piping connections. The G8 is designed for continuous duty industrial with clear, non-abrasive fluids.
Pump housing are investment cast in a variety of corrosion resistant metallurgies, with adequate wall thicknesses for hydro testing. Housings are finish machined on precision CNG equipment.
Metallic and non-metallic gears are machine generated. A variety of materials are available, and an existing pump can be quickly converted to satisfy different service conditions. Combination metallic and non-metallic gear sets allow the pump to handle low viscosity and non-lubricating fluids at standard motor speeds. This capability provides reduced noise levels and eliminates the need for larger pumps operating at reduced speeds. All gear materials are non-sparking for use with hazardous fluids.
Pumps do not require periodic lubrication, since the pumped fluids provides the necessary lubrication and cooling. In addition to reducing maintenance, this feature eliminates the possibility of contamination of the pump fluid.
Mechanical seals are available for the most demanding applications including single internal and external double seals. Two stuffing box design are also offered.
Because they are expressly designed for chemical service, ECO gear pumps do not include integral/build-by-pass or pressure relief valves. Design with these internal valves can cause heat build up in the pumped fluid, resulting in accelerated corrosion rates, possible vapor binding or even pump seizure. Instead, ECO recommends the use of externally mounted pressure relief valves, piped back to the fluids source. ECO can supply such relief valves, in various metallurgies, for many process requirements.
Optional features include bearing flush plugs and housing vent port. Available accessories include bolt-on heating/cooling jackets, pressure relief valves and backpressure valves.
Pump components, in all offered materials, are stock to provide quick delivery. A variety of constant or variable speed motors, with electric or air power, are also stocked for quick delivery of completely mounted and assembled pump packages. Pumps and replacement parts are stocked worldwide. |
