Axial flow pumps differ from radial flow in that the fluid enters and exits along the same direction parallel to the rotating shaft. The fluid is not accelerated but instead "lifted" by the action of the impeller. They may be likened to a propeller spinning in a length of tube. Axial flow pumps operate at much lower pressures and higher flow rates than radial flow pumps (the Black axial-flow pump in photo is a Griffin 24AX submersible pump).
A centrifugal pump is a rotodynamic pump that uses a rotating impeller to increase the pressure and flow rate of a fluid. Centrifugal pumps are the most common type of pump used to move liquids through a piping system. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller, flowing radially outward or axially into a diffuser or volute chamber, from where it exits into the downstream piping system. Centrifugal pumps are typically used for large discharge through smaller heads (the Red Centrifugal Pump in the photo is a Griffin 18NCRD).

The Wellpoint pump: (The 2nd pump from top) is designed to pump clean water/effluent for a wellpoint dewatering system and lowers the groundwater table to drain construction excavations. It is designed to have the highest air handling capacities on the market and can pump water while removing air without shutting the pump down. A typical 6 inch wellpoint pump is capable of pumping 1500 gallons per minute with head pressures of 100 feet or more. The water being pumped by a wellpoint pump must be relatively clean. Well suited for: wellpoint dewatering and sock dewatering.
Trash Pump: (The 3rd red pump from the top) Designed to pump clean or dirty/trash laden effluent most models will pass 3 inch solids without becoming clogged. It can be used to pump sewage or sandy water. These pumps can handle clean, muddy, mucky or sandy water with solids up to 3 inches in diameter, they incorporate an open impller and wear plate. A 6 inch Trash pump is capable of pumping 1500 gallons per minute with 125 ft. of head. Trash pumps are widely used because of their reliability and versatility. Well suited for: flood drainage, sewage bypass, pumping polluted wastewater, and pumping settled sludge.
High Pressure Jet Pump: (The 4th red pump from top) Designed to be used as a fire pump, jet casings or wellpoints without drilling/digging, for use in agricultural irrigation systems, and use in mining and quarry applications where high head capacity is required. Jet pumps are powerful pumps capable of pressurizing large amounts of water with high head capabilities. A typical 6 inch jet pump is capable of pumping thousands of gallons per minute of clean water with several hundred feet of head or more. Standard pumps just aren’t designed to handle much more than a 100-ft head. As anyone in the mining industry knows, sometimes you can go up a hundred feet and still be a long way from the discharge point. The typical high pressure jet pump is equipped to achieve discharge heads well over 500 feet. You won’t find another pump type that’s better at pushing water that far uphill. Jet pumps for high head and extreme high head situations. Well suited for: quarries/mining, jetting wellpoints, jetting casings, pipe cleaning, pipe testing, water blasting, and marine construction.
Hydraulic Submersible Pump: (The lower black pump) Designed for dewatering applications in construction, mining and sewer rehab projects. The benefit of using a submersible pump is that they can be used in areas that would flood and disable a conventional pump. Power units can be installed and operated remotely for safety from flooding, ease of maintenance and fewer space restrictions at the point of pumping. A well designed 6 inch submersible will fit into manhole openings. Hydraulic driven pumps can be an effective solution for applications with high heads and are not affected by "suction lift limitations". A limitation of submersibles is that they must be pulled out for inspection. Well suited for: open pit, lake unwatering, manholes, flood control, mining, and sewer bypass pumping.
Non-Clog Pumps: (Top Pump) These pumps offer the best of both worlds easily able to fill the role of a wellpoint pump in wellpoint excavation dewatering, while also working in well for sewage bypass pumping, sumping, flood control applications, or any other application pumping trash laden effulent. Their non–clog impeller is capable of handling stringy materials and solids up to 3” and large clean out ports offer hassle-free removal of large debris over 3” without removing suction pipe or hose. Well suited for: wellpoints, flood control, sewer bypass, and sumping.

If someone comes in and simply asks; “I’d like to rent a trash pump capable of pumping over 15,000 gallons per minute of trash laden effluent.” both of the pumps in the photo fit that criteria, but the renter really needs to give more information than that.
The black pump on the left is a Griffin hydraulic submersible pump (Model 24AX) capable pumping 20,000 gallons per minute and can pass 3 inch solids without clogging. The red pump on the right is a Griffin non-clog pump (Model 18NCRD) capable of pumping 17,000 gallons per minute and also can pass 3 inch solids without clogging. However, the Hydraulic Submersible Pump needs to be submerged in 8 to 10 feet of effluent to function properly and has about 1/7th the head capacity of the non-clog pump. The Hydraulic submersible is still the cheapest option to move large quantities of water, but has a few limitations that non-clog pump does not.
In order to get the right rental pump for your application you need to give all the specifics of your job to match you and your job with the correct pump.
Griffin Dewatering is able to provide bucket, auger or rotary drilling methods. These rigs can be either two-wheel drive, rough terrain or track mounted, depending on site demands and conditions. Griffin also has an extensive inventory of trailer mounted drill rigs and drilling support equipment.
On a construction site, this dewatering may be implemented before subsurface excavation for foundations, shoring, or cellar space to lower the watertable. This frequently involves the use of submersible "dewatering" pumps, centrifugal ("trash") pumps, eductors, or application of vacuum to a wellpoint system.
Griffin Dewatering can be engaged to provide a turnkey contract, after undertaking engineering studies, on-site pump tests, and other necessary investigations it requires to adequately define the project. This allows Griffin Dewatering to be in total control of the layout, installation, operation, maintenance, removal and abandonment ot the designed construction dewatering systems. Because this total concept is a comprehensive approach, it may include an assurance of obtaining specific groundwater control results, depending upon the specific site conditions.

Griffin’s Hydraulic Driven Submersible Pumps are available in trash, axial flow and materials handling models. The pumps range from 4” to 24” with a variety of impeller designs. These pumps are designed for handling high volumes of water up to 20,000 gpm and head conditions up to 140 ft. The impellers can handle solids up to 3”. Some models may also be used for high pressure applications.
The project shown was called the “Alameda Corridor” and was for the construction of a railway connecting the Port of Los Angeles to downtown Los Angeles. Construction of this railway allowed for a direct railway into Los Angeles without interrupting the normal street traffic by eliminating the need for Train Crossing Signals and Guards.
The majority of the railway was below street grade, most of which required dewatering as the high ground water table in the area would not allow the construction to be achieved.
Griffin was contacted by Tutor-Saliba (General Contractor) to provide the dewatering necessary to construct the project.
Griffin installed a multitude of deepwells along the alignment of the proposed railway to allow for construction. The discharge from the wells was pumped via large diameter High Density Polyethylene Pipe (HDPE) to a below grade mixing vault (shown in picture), where a neutralizing agent was introduced to the ground water as the quality of the groundwater was not allowed to discharge to the designated receiving area without this treatment.
Griffin Has provided service and equipment to the construction dewatering and groundwater pumping market since 1934. For over 75 years Griffin has gained the respect of our customers by applying all the right solutions to their groundwater problems on projects both large and small.

Dewatering by wellpointing involves installing a series of small wells (wellpoints) into the ground. These wellpoints are constructed of either PVC or galvanized steel pipe about 1.5 inches in diameter. The wellpoints are driven about 3 feet to 6 feet apart to the depth at which water must be eliminated or the water table must be lowered. Each wellpoint is connected to a common PVC header pipe up to 6 inches in diameter. The header pipe is then connected to a pump with a large amount of vacuum power. The vacuum power produced by the pump sucks the ground water up through thin slits cut into the walls of the wellpoints. The water then travels to the header pipe, through the pump and is discharged through an outfall line away from the site.

Whiting-Turner General Contractors hired Griffin Dewatering to provide a workable dewatering plan to facilitate the demolition of old, construction of new and maintain a “low profile” to accommodate everyday mall business. Challenges on this job included the dewatering process had to be environmentally compatible so as not to disturb daily business of the neighboring stores and eateries, limited locations for disposal of dewatering effluent, in addition to working only at night and after hours. Griffin installed a 300’ long x 6” I.D. discharge line under the existing floor slab (tile was cut and replaced), through a service corridor and into an outside service area where a 2,500 gallon weir type settling tank aerated the groundwater prior to its disposal into the onsite drainage system. A Griffin electric wellpoint pump was placed inside the mall (transported through service corridors), the motor size worked with the available three phase power and the General Contractor installed a flexible steel exhaust line to the adjacent ceiling fans to vent any water vapor or groundwater odor. Our shifts started @ 9:30 PM and concluded @ 6:00 AM.

Trash pumps are designed to pump large amounts of water that contains hard and soft solids such as mud, leaves, twigs, sand, and sludge. Most devices are portable, heavy-duty centrifugal pumps that feature deeper impeller vanes and larger discharge openings than other pumps. Trash pumps, which are capable of processing materials with suspended particulates that would clog other centrifugal pumps, can move hundreds or even thousands of gallons per minute. Semi-trash pumps, a type of trash pump with a smaller opening, are not designed to handle large solids or high concentrations of solids. Consequently, regular trash pumps are better suited for applications that require the rigorous pumping of solid-laden water or slurries.
Trash pumps are available with a variety of features. Run dry capable pumps can operate without pumped fluid or external lubrication for an extended period of time. Self-priming pumps are designed to create and maintain a vacuum level that is sufficient to draw fluid into the inlet without external assistance. Non-clog pumps can move sticky or stringy materials.
Important specifications for trash pumps include maximum discharge flow, maximum discharge pressure, inlet size, discharge size, and horsepower.
Trash pumps are used in a variety of industrial, municipal, and specialty applications. Examples include agriculture and horticulture, construction, flood control, mining, and oil and gas production, and pulp and paper production.

In open sump pumping, hydraulic submersible pumps are a good choice due to the high volume and high head capability. The lighter weight over conventional electric submersible pumps allow for easier placement in sumps. For heavy sludge materials such as drilling muds, the material handling hydraulic submersible pump is very good at overcoming the flow resistance and transferring the fluid. A good example is where casings are being drilled and the hole is stabilized with drilling mud. The pump can be used to transfer the drilling mud into the hole from the tank, and then used in the hole to circulate the mud, and then transfer back to the solids control equipment.

A typical request may ask for a diesel driven pump capable of pumping 500 gallons per minute (GPM). Well, there are multitudes of pumps that will meet this requirement. In this photo for example there are three pumps.
The pump on top is a Wellpoint pump designed to pump clean water/effluent for a wellpoint dewatering system and lowers the groundwater table on construction excavations. It is has one of the highest air handling capacities on the market and can pump water while sucking air without shutting the pump down. A 6 inch wellpoint pump is capable of pumping 1500 gallons per minute with 145 feet of head.
The middle pump is a Trash Pump designed to pump clean or dirty/trash laden effluent and pass 3 inch solids without becoming clogged. It can be used to pump sewage or sandy water. A 6 inch Trash pump is capable of pumping 1500 gallons per minute with 125 ft. of head.
The lower pump is a High Pressure Pump (or Jet Pump) designed to be used as fire pumps or to jet casings or wellpoints without drilling/digging or agricultural irrigation systems. A 6 inch jet pump is capable of pumping 1300 gallons per minute with 600 feet of head or more.
Need a pump to water with sand or sludge in it?
The 6” jet pump and the 6” wellpoint pump will clog and stop working. The 6” trash pump is the pump you need.
Need a pump with over 300 feet of head?
The 6” trash pump and 6” wellpoint pump will fail to push the water half that high. The 6” high pressure (jet) pump is the pump you need.
Need a pump that can handle sucking air along with water while pumping?
The air will cause both the 6” trash pump and 6” jet pump to stop pumping. The high air-handling capacity of the wellpoint pump makes it the correct pump for this application.
All of these are 6” inch certifugal pumps, but all are very different from each other and can are designed for different types of jobs.
Always remember when determining a pump for an application, there are a number of factors to consider. Among them are flow requirements, head conditions, suction requirements and dimensional limitations.
Griffin has 75 years of field experience with pumps and 75 years of pump manufacturing experience as well. For more information on Pumps please visit: www.griffinpump.com

pumps contain two pumps, one primary and one backup. The pumps can be change to different HP to accommodate the anticipated flow. This has a much smaller footprint than conventional pumps for areas with limited access.
