ECO Gearchem

GA12 Gearchem Pump

Stocked in 316 SS, Alloy C, and Alloy 20.

Standard features include bearing flush plugs and center housing drain connection. A center housing vents port is available as an optional feature. Additional accessories include bolt-on heating/cooling jackets, pressure relief valves and back pressure valves.

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.

This self-priming, external spur gear pump has 11/2-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 maybe 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 levels and eliminates the need for larger pumps operating at reduces 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.
