GPM

GPM, Inc. has been providing equipment and service to the industrial markets since 1978. Covering the power generation, mining and other heavy industrial markets. GPM is the original manufacture of the Eliminator slurry pump line.

Eliminator severe duty slurry pumps are built to handle even the most abusive applications. From dirty water to 70% solids. We think the goals for every pumping systems should be:

  • Make the system simpler, not more complicated.
  • Design it to need less maintenance, not more.
  • Design the system to maximize profit, not maintenance costs.
By “eliminating” the low-cost features that other vendors use, you can achieve these goals.
We use a mechanical seal to eliminate:
  • Worn shaft sleeves
  • Messy seal water flush
  • Time wasted on packing adjustments
  • Bearing contamination from flush water
We use 28% hi-chrome materials to eliminate:
  • Premature impeller and casing wear
  • Regular replacement of parts
Our submersible motors use Class H winding insulation to eliminate:
  • Motor damage from run-dry conditions
We oversize our pump shafts to eliminate:
  • Lower bearing failures
  • Mechanical seal damage

Power Generation Applications for GPM-Eliminator Slurry Pumps

 

GPM Eliminator Slurry Pumps

 

Coal Handling (1, 2, 3, 4)

Coal fired power stations have several GPM-Eliminator applications. Several of which are in the fuel feedstock area.

Coal Car Dumper Building
Coal arrives via train. Each car is emptied in a dumper building. The coal falls into the basement and eventually hits a conveyor and is moved above ground to the live storage pile. Dumper Buildings always have a sump on the very most bottom floor. This sump collects water which arrives with the coal (snow, ice, etc), water ingress from the earth around it, and washdown water. Operators use firehoses to washdown the equipment regularly to remove coal dust. All this stuff washes into a sump. The sump pump must be able to handle coal dust, coal chunks, floor wash (gloves, sticks, rope, twine, wire, etc). Typically the motor must be rated for a Class 2, Group F rating. The GPM-Eliminator XP motor does not meet this rating. An extended shaft is typically used. GPM has many installed pumps in this service. Many are submersibles, dating to a time when the motor rating was not of importance. Typically the pump is rated for about 100gpm and must raise the water about 80’ and discharges into the atmosphere above ground.

Coal Pile
Most coal piles are surrounded by a ditch of some type. Plants typically must contain all water which runs off of the pile. There are typically in-ground sumps around the coal pile where GPM-Eliminators can be used. Flowrates are usually 100-200gpm and head can vary depending on how far away the water treatment system or holding pond is.

Coal Crushing
Plants often have a course coal crushing system. These large crushers are typically located in a building. This sump collects water which arrives with the coal (snow, ice, etc), water ingress from the earth around it, and washdown water. Operators use firehoses to washdown the equipment regularly to remove coal dust. All this stuff washes into a sump. The sump pump must be able to handle coal dust, coal chunks, floor wash (gloves, sticks, rope, twine, wire, etc). Typically the motor must be rated for a Class 2, Group F rating. The GPM-Eliminator XP motor does not meet this rating. An extended shaft is typically used. GPM has many installed pumps in this service. Many are submersibles, dating to a time when the motor rating was not of importance. Typically the pump is rated for about 100gpm and must raise the water about 80’ and discharges into the atmosphere above ground.

Dirty Water Handling (18, 19, 20)

Coal fired power stations typically use river water as the main process fluid.

River Intake Dredging
Over time the river water intake structure can silt in from the natural river flow. We’ve successfully supplied end-users and dredging companies with GPM-Eliminator pumps to dredge and remove sediment from the mouth of the intake structure.

River Water Intake
Most power stations draw water from a river or lake. An entire system is in place to remove debris from the water before it enters the plant. Typically water enters the plant through a Screen House. Inside this building you’ll find general sumps. The typical application here is moving sand and silt and other river debris (fish, sticks, etc).

Plant Drains
The basement of the boiler house always has general sumps. These sumps collect washdown, spilled process water, floor drains, and anything else. Standard GT and LH submersibles are a great solution for these sumps.

Other key words are: Main Plant Collection Sump

Condensate Blowdown
On occasion steam from the boiler is released and falls into a floor sump. This water is generally very clean, but it is hot sometimes pushing 180F. Most competitors will not last in this environment. The GPM-Eliminator is a very good fit. When selecting an GPM-Eliminator, use one motor HP size larger than is required. This allows the motor to run cooler and last much longer.

The basement of the boiler house always has general sumps. These sumps collect washdown, spilled. After steam passes through the main turbine, the steam is condensed back to water. Typically this occurs in a Condenser. The Condenser is often located on the lowest floor of the power plant. Condensers receive dirty water from a pond or river. The Plants often have a course coal crushing system. These large crushers are typically located in a building.

Water Treatment
Power stations must treat and prepare water for use in all the various systems they own. This water treatment typically involves chemicals. On upsets, or when draining equipment, these chemicals typically flow into sumps and must be pumped to other locations, such as the water treatment pond. These are great applications for the GPM-Eliminator.

*** Because chemicals are in use, care must be taken to properly select the pump materials of construction ****

Other key words are: Caustic Sump, Site Retention Pond, Condenser Sumps, Polisher Sump, Neutrilization Sump, Cooling Tower Overflow

 

Pollution Control


Pollution control systems often require the use of other minerals in order to scrub the flue gas clean.

Flue Gas Desulfurization
Typical systems require the use of limestone. Limestone is received typically received by rail or truck. The offloading building typically has sumps.
Limestone is often crushed or pulverized and prepared for use in the spray dry absorber vessel. These buildings (often Lime Prep Building) has sumps. Sumps will receive water, limestone, rock, sand, floor wash, etc. GPM-Eliminators are very good for these applications.

Other key words are: Scrubber Sludge, Spent Lime Slurry

Ash Handling
There are two types of coal ash: bottom ash and fly ash. Bottom ash typically falls out of the bottom of the furnace. Typically a large pit is under the boiler furnace and the bottom ash is collected here. Slurry type sump pumps are regularly used here to move the ash to other locations.

Fly ash is typically removed from the flue gas in the after parts of the boiler, such as the economizer. Fly ash is usually transported by an air vacuum system. You may find sumps in the fly ash area as well.

Other key words are: Clarifier Ash Tank, Bottom Ash, Ash Loadout Sump
