This self-priming, external spur gear
pump has 1 1/2-inch FNPT or BSPT, or
150 lb. raised face ANSI horizontal
ports, and will deliver flows up to 28
gpm. Maximum rated discharge pressure for this pump is 150
psig with metallic gears and to 100 psig with a combination of
metallic and non-metallic gears. Designed for simplified
maintenance, the pump may be quickly disassembled without
the need to break piping connections. The GA 12 is designed
for continuous duty industrial applications with clear, corrosive,
non-abrasive fluids
Metallic and non-metallic gears are machine generated. A
variety of materials is 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
fluid provides the necessary lubrication and cooling. In addition
to reducing maintenance, this feature eliminates the possibility
of contamination of the pumped fluid.
Mechanical seals are available for the most demanding
applications including single internal and double mechanical
seals. Two packing box designs are also offered with a variety
of packing material.
Because they are expressly designed for chemical service,
ECO gear pumps do not include integral/built-in by-pass
pressure relief valves. Designs with internal valves can cause
heat build-up in the pumped fluid, resulting in accelerated
corrosion rates, possible vapor binding or even pump seizure.
ECO recommends the use of externally mounted pressure relief
valves, piped back to the fluid source. ECO can supply such
relief valves, in various metallurgies, for many process
requirements.
Standard features include bearing flush plugs and center
housing drain connection. A center housing vent port is
available as an ootional feature. Additional accessories include
bolt-on heating/cooling jackets, pressure relief valves and back
pressure vatves.
Pump components, in all offered materials, are stocked 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 also stocked in
Europe.
