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).

At this photo you can see ready for use PEX manifolds with connected red PEX Tubing 1/2 inch size(most popular size). PEX manifold for radiant heating is always established with air scoops.
Griffin installed a multitude of deepwells along the alignment of the proposed railway connecting the Port of Los Angeles to downtown Los Angeles to allow for construction. The discharge from the deep 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.
Compare the prices, installations, expectancy of PEX tubing and copper piping to help understand the differences between two popular pipe materials for plumbing and heating. PEX tubing provide from best USA manufacturer: Everhot & Bow Group.

This is a 100 hp, steam driven beam engine, built in 1886 to pump sewage effluent from settling tanks to the filter beds that cleaned it enough to be released into the River Lea in Tottenham, north London.
This is looking at the hub of the flywheel. The engine is run a few times a year.
Many thanks to the volunteers that look after and run the engine, who were extremely helpful and eager to explain and show off all aspects of it.
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.
Griffin has 75 years of field experience with pumps and 75 years of pump manufacturing experience as well. For more information on Griffin Pumps please visit: www.griffinpump.com
Griffin Dewatering has been in the pump and dewatering business for 75 years. Not only does Griffin have a standard line of pumps to fit most applications, but also specializes in providing pumps to meet a customer’s specific needs. The shown pump had not only specific flow and head requirements, but also suction and discharge height requirements that had to be met. Griffin designed and special built a custom trailer mounted pump package to meet the customer’s need, which included automatic level sensing transducer control that controlled the engine speed to meet the varying flow demands.

Around a bend on the Chicago river stands this gleaming white palazzo: an exclusive boat club, with a high-ceilinged ballroom and a broad marble terrace, compleat with obelisk-studded balustrade for laughing ladies to langorously lean upon during swanky cocktail soirées? No. Its use becomes quite evident upon closer, uh, examination: a sewage pumping station. Once upon a time, Americans cared enough about their public realm—about civic art—to endow even the humblest of shit pumps with architectural grandeur.
(A slightly closer look reveals extensive graffiti under those arches, *on* the giant sewage pipes. Kids these days.)
The mixing vault shown consisted of a below grade concrete sump into which the groundwater was pumped from the dewatering wells. A metering pump dispensed the neutralizing agent into the effluent based on incoming flows. Installed into the vault were three 12” Hydraulic Driven Submersible Pumps (Griffin Model 12T Submersible Pumps with 825 Power Units). These pumps would then pump the treated groundwater to a receiving point approximately one mile away. Link: www.griffindewatering.com/pumps/submersible_pumps.html
Griffin can provide pumps that meet any of these requirements for the given project needs. Trash pumps are used in a variety of industrial, municipal, and specialty applications. Examples include agriculture, construction, flood control, and mining. The choice depends on whether the pump is intended for a dedicated function or whether a more versatile pump is required. Each pump owner should consider whether air-handling, priming time, or simply volume are required in order to determine the best match of a pump. This also ensures that the pump chosen is a cost-effective solution to the anticipated problems and also includes the features required to successfully complete the project.

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. Link: www.griffindewatering.com/pumps/index.html

A temporary pumping station was installed to supply downstream water users, when construction of a hydroelectric plant on California’s Lake Isabella required shutting off the flow from the main dam.
Lake Isabella is a primary source of water for farmers in the southern part of the largest agricultural area in California. Supply problems caused by the shutoff were exacerbated by drought conditions that had caused water shortages.
Griffin Dewatering designed, constructed and operated the pump station, which was capable of pumping 200,000 gpm (gallons per minute) with a standby capacity of 30,000 gpm. The station was outfitted with two 36inch vertical axial flow pumps and fifteen 24 inch axial flow pumps.
The system operated for about five months, according to Susan Young, assistant to the project manager for Isabella Partners, Lake Isabella, Calif., which was constructing the 16 MW plant. “The pump station worked very well. We’ve gotten repeated compliments from the downstream water users about the system. Believe me, that’s unusual,” she says.
