This Series GA 16 Gearchem pump has 2-inch 15O lb. ANSI
raised face flanged-ports. This gear pump is designed for transfer
and circulation of corrosive, clear, non-abrasive fluids at flow
rates in excess of 50 gpm at pressures up to 100 psig.
The GA 16 Gearchem can pump fluids with viscosities ranging
from less than 1cP to 100,000cP and higher. Pump housings are
investment cast in a variety of corrosion resistant metallurgies,
and components are finish machined on precision CNC equipment.
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. Non-sparking gear materials can be supplied 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.
Like all Gearchem pumps, the Series GA 16 contains two
machine-generated spur gears. Rotating in a closely machined
center housing and flanked by replaceable wearplates, which
protect the faces of the end housings, these gears provide a
self-priming pumping action.
In the Gearchem pump, the gears may rotate in either direction,
and by reversing drive shaft rotation, the direction of flow
can be reversed.
Displacing a constant volume for each specified drive speed,
these pumps provide linear, pulsation-free flow. Packages are
available for indoor or outdoor location and the pumps are rated
for intermittent or continuous service.
Three standard shaft sealing arrangements are: packed
lantern ring box, single internal or double mechanical seals. Consult factory for special sealing requirements. Bearing flush
ports, center housing vent port and drain connection are
standard.
Because they are expressly designed for chemical service,
ECO gear pumps do not include integral/builtin bypass or
pressure relief valves. Designs 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 fluid source.
This pump incorporates all of the engineering experience
gained by ECO in over 30 years of designing, building and testing
process pumps and the materials that to into them. There is the
added feature of parts interchangeability with the Series GA 12
Gearchem pump. Pump components, and a variety of constant or
variable speed motors are stocked for quick delivery. Pumps and
replacement parts are also stocked in Europe.
