Industrial Centrifuges FAQ
QUESTIONS ABOUT INDUSTRIAL CENTRIFUGES
Industrial Centrifuges work on the principle of different specific gravities separating into different phases under extremely high “g” force. If you have dissolved liquids there is effectively no difference in specific gravities for the centrifuge to separate. Therefore centrifuges of any type cannotseparate dissolved liquids or solids dissolved in liquids (i.e. Salt / Water).
“Self-Cleaning” centrifuges are capable of separating upto 5% sludge (by volume) due to the inherent design of these types of centrifuges. For high sludge applications we recommend horizontal decanter type centrifuges which are capable of separating high sludge content fluids upto 30% or more in some cases.
As the name implies, “Manual Clean” centrifuges are designed for liquid/liquid separation of 2 immiscible liquids with no solids or very low solids contamination (< 0.5% by volume). Typical applications include separation of water from diesel fuel; separation of water from turbine lube oil; biodiesel separation from glycerin etc.
“Self Cleaning” Centrifuges have more extensive uses. They are designed for liquid/liquid/solid separation. Though these are “self cleaning” centrifuges, they can separate fluids with upto 5% (by volume) solids. Any ratio of the 2 immiscible liquids can typically be handled by these types of centrifuges. Typical applications include separation of crude-oil from salt-water and sediment; fuel oil separation from water and sediment; wvo separation from water and sediment; used motor oil separation from water and fine metal particles etc.
Most industrial centrifuges operate on 460 Volts AC power. The small centrifuges (1-2 GPM) use 1HP motor and the largest (100+ GPM) can have 50HP or larger motors on them.
Requirement of explosion proof components / systems are entirely defined by your local codes (or rules). Dolphin Centrifuge is unable to verify applicability of your local codes. The customer (you) needs to contact the appropriate authorities to ascertain the requirement of such codes.
Dolphin Centrifuge has in-house capability to design and manufacture explosion proof centrifuge systems.
QUESTIONS ABOUT DOLPHIN CENTRIFUGE
Dolphin Centrifuge is a Michigan incorporated company specializing in Alfa Laval industrial centrifuges for over 25 years. Industrial Centrifuge is ALL WE DO.
The main difference between Dolphin and other centrifuge suppliers is that Dolphin is essentially a engineering company specializing in industrial centrifuges. Dolphin is NOT a used equipment dealer who also sells centrifuges.
The other major difference is that Dolphin Centrifuge has an inventory of over 100 good used & new centrifuges of all sizes and types (all Alfa Laval) – at our Warren, MI factory. This large inventory allows Dolphin to offer pre-selected good, used centrifuges to prospective customers. Dolphin does NOT list equipment that it does not own! All images shown on our web-site are of Dolphin supplied centrifuges – most reconditioned.
In addition to the “no-charge” training available at the Dolphin Centrifuge factory in Warren, MI; we provide on-site start-up and training at your facility. These services are typically not included in the cost of the base centrifuge system, however we can provide a comprehensive proposal to included start-up & training, based on customer requirement.
Good Question! As previously mentioned, Dolphin Centrifuge has been in the centrifuge business for over 35+ years during which we have delivered hundreds of centrifuges throughout the world. Yes, we can provide you references of customers who have been with Dolphin Centrifuge for years.
