Re Crisafulli Pumps . . . Here is what Mike Green, Sales/Operations Manager, West Pac Environmental, Inc., Seattle, WA 98134 (Tel 208 762-1190) says about Crisafulli Pumps after using Crisafulli Pumps in connection with Exxon's Valdez, Prince William Sound oil spill cleanup . . "The Crisafulli pumps were run 24 hours daily and in an environment that would destroy almost anything with moving parts. However, this hostile atmosphere did not challenge the incredible performance of our Crisafulli pumps". . . "The integrity and performance of the Crisafulli pumps was outstanding." Mike Green offered the foregoing assessment after using Crisafulli Pumps to offload 10 million gallons of sour crude with a heavy paraffin and high sulfur content, emulsified with sea water, heavy and viscous, a gluey mousse riddled with seaweed, kelp, rocks, and other debris.

Francis D. Gregerson, Gregerson Dairy, Longmont, CO, 80504 Phone: 303 776 2783
Gregerson's Colorado Dairy Farm, running 1,500 head, moves liquid manures, fluids and sludges with four Crisafulli pumps: two electric vertical pumps, a six-inch PTO trailer mounted pump, and a 7.5 horsepower electric lift pump.
"We have not experienced trouble with any of these pumps, not even over the summer months when we use both the trailer mounted pump and the lift pump intensively for irrigation."
"Maintenance on the two pumps used to pump liquid manure and run-off usually comes down to a rebuild. The SRS Crisafulli factory in Glendive has been excellent when it comes to service. With a little notice, they are usually able to rebuild our pumps in a day. The life of a SRS factory rebuild, with our usage, is about a year to a year and a half. When we have rebuilt the pumps ourselves, or have had it done locally, the rebuild will usually only last about six months."
"All in all, I have been very satisfied with both the performance of my Crisafulli pumps and with the service of the SRS Crisafulli staff. The sales, office and service departments have all gone the extra mile whenever I have contacted them. I would certainly look into the SRS Crisafulli pump line if I was in the market to purchase another pump and I would not hesitate to recommend Crisafulli to anyone else needing a pump."

Crisafulli Vertical Pumps
These are excerpts from a report prepared in 1998 by NORTHWESTERN POWER EQUIPMENT CO. INC.,
P.O. BOX 131180

Regarding the purchase and use by affected cities, as advised by the U.S. Army Corps of Engineers of 27 Crisafulli Vertical Pumps in sizes ranging from 10" to 16" for flood control applications along the Red River Valley of the North.
"During the winter of 1996-1997 there were seven or eight major blizzards and heavy snowfall in this watershed area. The Canadian portion of this watershed was still frozen when the spring thaw hit in 1997. Most of the dikes along the Red River were not built high enough to accommodate this much water. All of the predictions from the Corps of Engineers and expert hydrologists were below what actually occurred. The flood waters rose to record levels and stayed for up to six weeks in some areas.
The U.S. Army Corps of Engineers, along with several consulting engineering firms, has been busy in the last year designing and building higher levees and/or bypasses for some of the communities along the river. A billion dollar ditch that bypasses Winnipeg was instrumental in saving most of this city. However, the Corps of Engineers has determined that this type of construction is not cost-effective for many of the communities along the Red River in the USA. Most communities, therefore, are enhancing their dike and Storm water systems by installing more permanent pumping and control structures.
Most of these communities are familiar with the tractor-driven Crisafulli pumps so it was natural for the engineer on the Breckenridge (MN) project to utilize this design in a permanent installation. He actually prepared and took two separate specifications: one for a vertical propeller pump, and one for the Crisafulli design. Even though the Crisafulli pump required more horsepower, it was a better application for this project because it did not require screening.
Another feature of the Crisafulli pump, as you will notice in the pictures, is its low profile. Even with the right angle gear drive option, it was three or four feet shorter than the propeller pump with a combination right angle gear drive. The aesthetics of this lower profile are significant when the pump is located on top of a 25 foot high dike. It also lends itself to any future fiberglass enclosure that could be installed in the future for vandalism protection."

Regarding a STORM WATER MANAGEMENT CASE STUDY for the Winnetka, Illinois Department of Public Works (see photo above). The Town uses the following Crisafulli equipment to solve its problem:
PROJECT DESCRIPTION: To transfer storm water from a creek to an adjacent river during periods of high water during storms and spring thawing. The storm water from the creek contains a large amount of debris and sticks.
KEY ELEMENTS OF JOB: The situation during storms and high water runoff was a need to move large amounts of water containing debris in a short amount of time because of the narrow creek width. Also, electric power was frequently unavailable during storms because of power outages.
SOLUTION: The customer first purchased a Crisafulli 12" PTO Humpback Trailer Pump because of its non-electric power requirement, high volume pumping and potential ability to pass debris from the channel. After using the trailer pump effectively through one storm season, the village purchased a Crisafulli 16" vertical PTO pump to supplement the trailer pump for this application. During the same year a new lift station was being designed for storm water management at another site in the village. (One questions was) what type of power source (electric or PTO) to use on this application. A Crisafulli l6" Vertical Electric/PTO was chosen. . . electric power is cheaper than manning a PTO driven pump, but if electricity is not available the PTO drive still works.
The specification for this project was written around the Crisafulli Pump because of it’s proven track record with the village. The next year brought the design of an additional three pump storm water stations for the creek to meet the final design and complete pumping requirements for this site. This application was designed by a consulting engineering firm and not by the village as the previous applications were. The engineer chose pumps (not made by Crisafulli) for the application. The complete project cost for the three pumps, lift station and controls was over $100,000.00; equipment only. Some of the village managers were not happy with the final cost after seeing the performance and price of the Crisafulli Pumps in the past on the same application. The project was completed and the results were unsatisfactory with the competitor's pumps. They could not handle the debris from the storm water runoff and had drastically different pumping rates at different heads. There was also some conflict with the engineer’s total head condition estimate and the actual total head. These problems are not uncommon for a cast rather than a fabricated pump.
The competitor's pumps were eventually replaced by three Crisafulli 16" Vertical Pumps for about half of the cost of the axial flow pumps." After the success of the Crisafulli Pumps for the village, the decision for them to buy a Crisafulli hydraulic pump for a replacement to an existing competitor’s pump was a given. This pump is used by street department personnel to dewater various pits and manholes.
RESULTS: The Crisafulli Pump line offers a variety of pump configurations, drive designs and control packages to meet the most demanding applications for any client. The fabricated design offers the benefits of flexibility and capability of passing heavy solids and debris without sacrificing flow. Customers have also commented on the simplicity of the pump design and the ease of maintenance and serviceability of the Crisafulli Pumps."

We would like to thank you for your wonderful flump. We have been dealing with our wet sludge lagoon for many years and have not always been totally successful. We found your system to be of excellent design and robust construction. The control system is direct and easy to understand.
I must say we were a little apprehensive about renting a machine, sight unseen, from the wilds of Montana, but the flump has exceeded our expectations. The setup diagrams were most helpful; however, the best part was that you were just a phone call away to answer the few questions we did have.
From beginning to end, you, your machine and the people who work for you are clearly first rate. We are looking forward to purchasing a sludge pump system and yours is certainly our first choice.

This letter is to inform you of our success using SRS Crisafulli standard duty flumps to remove settled solids from two of our primary settlings basins at the Hanahan Water Treatment Plant. The two basins were built around 1904 and had no provisions for removal of settled solids other than draining the entire contents. These basins contain approximately six million gallons each and product twenty-two million gallons of treated water per day each. The draining of either of these units every four months caused immense loading problems for our solids handling facility, not to mention the loss of a major portion of our water production capacity. This often occurred during peak demand periods when volume and water quality were critical.
We began looking at sludge dredges but were very cautious of cutter heads that might disturb the settled solids blanket affecting water quality. Our goal was simple. Remove the solids on a continuous basis without affecting water quality and keep both basins in service while this was being performed.
We purchased a standard duty flump and removed and replaced the cutter head with a siphon manifold. We were able to remove solids at a rate of 300 to 500 gallons per minute on a daily basis without affecting water quality. Shortly, we purchased a second flump and made the same modification. The use of these two units has allowed us to solve two major problems at the Hanahan Water Treatment Plant.
We have been very pleased with the service that these units have provided and would recommend them to anyone having a similar problem.
Crisafulli Rotomite™ Dredge

said this in a letter to Crisafulli's Sales Engineer on June 25, 1996 about Crisafulli's Rotomite Dredge:
"The Rotomite 180 has performed very well for us . . . . Our application is a very bad environment dredging in a caustic soda mud lake. All components are fine to this point except the few aluminum parts which we expected to be sacrificial. Crisafulli was very prompt in replacing these with steel parts. After changing these parts, the dredge is doing very well. . . . The machine maneuvers in our thick-mud much better than we expected. This lake is actually a mud lake that the liquid drains off of and leaves a very thick mud to be dredged. The capacities of solids varies in our application but has a high average for the service in which it is used.
This dredge is highly recommended by us for our operation and needs. It is well suited for a two man operation and does not take a competent person very long to get the feel of operating the cutterhead under thick mud."

1993 DREDGING CASE STUDY
Project Location: Northern Illinois
Equipment: Rotomite 180P Self Propelled Dredge
"PROJECT DESCRIPTION: To dredge benzyne from the bottom of a 12 foot basin approximately 1000 feet long and 500 feet wide and discharge it into the water column so biologic treatment (BUGS) could work.
KEY ELEMENTS OF JOB: The customer had an existing conventional cable hydraulic dredge doing the work for about two years. The problem was that the discharged dredged material would only stay suspended in the water column for about 10-15 minutes and then settle back down to the bottom of the basin. Therefore the exposure time for the "bugs" to react with the benzyne was poor. Another problem was the layout of the basin. The basin was irregular in shape making complete dredging impossible with a conventional dredge. Additionally there were a number of floating aerators in the pond suspended and secured by cables making maneuverability hard and costly to reposition the conventional cable dredge.
SOLUTION: The customer procured a Crisafulli Rotomite 180P self propelled dredge on a lease/purchase option basis. The Rotomite 180P was equipped with a 180 horsepower turbo-charged diesel engine, hydrostatic hydraulic power/control unit and a special cutter head with an "agitator" head. The agitator head would shear the dredged benzyne material to a much finer degree and therefore increase the surface exposure to the "bugs" and provide a much longer exposure time for the "bugs" to work.
RESULTS: The self propelled feature allowed the operator to dredge in areas where the conventional dredge could not. Also the operator could traverse the basin in any direction at any time without waiting to reposition the cabling system as with the conventional dredge. The labor cost alone saved the customer about $250.00 per day not to mention the increased productivity time of the Rotomite 180P. Additionally, the special "agitator" head was estimated to increase the solids suspension /exposure time by 200%."
