Oil Interceptors

By Zurn

Oil interceptors are designed for use in drain lines where oils, sediment and other liquids are found. These drain lines may be from areas in parking garages, machine shops, service stations, aircraft hangars, industrial and manufacturing facilities, etc., and all need an environmentally sensible way to drain off. For an effective, durable way to drain, try a Zurn oil interceptor.

Oil Interceptors & How They Operate

The solid baffle plate opposite the inlet to the oil interceptor diffuses the flow into the interceptor and lessens the turbulence of the oil-laden water as it enters the intercepting chamber. Solids and sludge carried in the water are stopped by the baffle and collected in the solids retaining bucket between the inlet and the flow-retarding baffle. Such accumulation can then be removed. The resulting quiet, even flow of water through the interceptor permits the oils and other light density substances to rise to the surface by the "flotation" principle of separation. Oils are lighter than water, therefore gravity causes the oil to rise to the surface of the water. Maximum separation and interception is affected in proportion to the elimination of turbulence of wastewater within the interceptor. The unique baffle/bucket design permits almost 90 percent of the interior of the interceptor to be used for the function of oil separation. They are constructed of 100% steel for long lasting performance and durability.

Installation Considerations:
Install the interceptor in the building sewer line. The interceptor may be set on the floor, partially recessed in the floor, top flush with the floor, or fully recessed below the floor to suit piping and structural conditions. All Zurn oil interceptors with oil level sensors must be installed sitting on the floor or recessed in a pit. Pit installations require the pit be kept dry by means of a drain or sump pump. Be sure to anticipate sufficient clearance for removal of interceptor cover for cleaning. Also take into consideration the placement of flow control fittings, vent requirements, and draw-off piping. All oil interceptors must be vented to the atmosphere.

These Interceptors are great for commercial and industrial applications such as: filling and service stations, maintenance garages, auto shops, airport hangars, carwashes, laundries and cleaning establishments, parking facilities, wash down areas, machine shops, refineries, fabrication and welding plants, foundries, electrical substations or anywhere oil can be spilled and possibly leak into a sanitary drain system.


Oil Interceptor Z1186
Acid resistant coat oil interceptor

These oil interceptors feature fabricated steel construction with an acid resistant epoxy coat on the interior and exterior, bronze cleanout plug, visible double wall trap seal, removable combination pressure equalizing/flow diffusing baffle and sediment bucket, horizontal baffle, adjustable oil draw-off and vent connections either side, secured gasketed non-skid cover complete with flow control fitting and a threaded inlet and outlet.
Note: Location of outlet from bottom of interceptor cannot be changed.
This Zurn Z1186 oil interceptor is furnished with a 1-1/2" NPT adjustable oil draw-off assembly. Since oils are lighter than water, gravity causes the oil to rise to the surface of the water. The oil draw-off assembly allows the separated oils, and other similar light density substances, to be automatically drained out through a properly adjusted internal stand pipe. A pipe connection from the internal adjustable standpipe is connected to an oil drain line leading from the oil interceptor to an oil storage tank. The standpipe sleeve (brass tube) must be adjusted so the opening is 1/8" above the top of the normal water flow level in the interceptor chamber. The oil that floats to the surface will drain off by gravity flow as waste water flows through the interceptor. When the adjustable sleeve in the standpipe is correctly set, no water will drain off with the oil. There is no need for any manual skimming of the oil.

Oil And Sediment Interceptor
Oil and sediment interceptor
Click here for detailed dimensions
These Oil & Sediment Interceptors Feature: an acid resistant coat on the exterior and interior, fabricated steel construction, bronze cleanout plug and visible double wall trap seal, removable sediment bucket, horizontal baffle, internal vent connection, with Dura-Coated heavy-duty cast iron grate.
The Zurn #Z-1189 Oil and Sediment Interceptor was created for garage and industrial floor drainage applications. They can be used in service stations, vehicle maintenance facilities, garages, auto shops, carwashes, fabrication and welding plants, airport hangars, laundries and cleaning establishments, parking facilities, machine shops, refineries, foundries or any other floor application where oil could be drained into a sewer drain.
This interceptor is constructed to not only retain any waste material containing oil or grease, but will also hold and keep mud, sand, sediment, greasy sludge or any other solid material entering into it. The Zurn #Z-1189 interceptors must be manually cleaned on a regular basis to avoid oil or sludge passing through the interceptor and into the sanitary drain system.
How this interceptor works: Waste water flows through the grate at the top of the interceptor into the sediment pan where greasy sludge and solids are detained. The waste water then continues down into a removable retaining bucket. There, any mud, sand, sludge, and other solid material will be retained until manually removed. The waste water then flows over the top of the retaining bucket spilling into the main separating chamber. Any oil will float to the top of the separating chamber allowing just waste water to flow down through the secondary screen and out into the cleanout chamber. From the clean out chamber, the now separated waste water exits the interceptor and continues onto the sanitary drain system. The efficiency of this oil and sand interceptor will be directly determined by the level of maintenance it will receive.

Please note: As there is a possibility that vapor given off by the flammable liquid could ignite, it is extremely important to have a vent that terminates in the open air at an approved location above the highest part of the building.

These units must be properly installed, due to the dangerous nature of the oils and gas being separated by these systems, as is specified by local codes and regulations.

Frequently Asked Questions

Q. "How often should I clean the oil interceptor"
A. Cleaning should be done on a regular basis, either before or after sediment pan passageway becomes blocked. Remove the grate, sediment pan and bucket, and clean out all debris. Skim oil/grease from top of water or pump contents out. After cleaning all materials should be disposed of properly. Efficiency of operation is directly related to the level of maintenance. Cleaning should be done regularly to avoid oil/sludge from passing through the unit.

Q. "What is a liftgate and how do I know if I need one or not?"
A. A liftgate is a device on the back of a freight truck used to raise and lower items from the ground to the truck. The bed of a freight truck is about 56" high and is designed for loading/unloading at a loading dock or with a fork-lift, not to and from ground level, so getting very heavy or bulky items on and off the truck can sometimes be a challenge. If your delivery location is a residence or does not have a loading dock or fork-lift and the item is too heavy to remove from the truck by hand, you will most likely need a liftgate.

If your delivery location has a loading dock or fork-lift, you won't need a liftgate. Alternatively, some large or bulky items may be lightweight enough for you and your staff/friends/neighborhood teens/etc. to remove them from the truck, in which case you wouldn't need a liftgate either.

"We should be careful to get out of an experience only the wisdom that is in it - and stop there; lest we be like the cat that sits down on a hot stove lid. She will never sit on a hot stove lid again -and that is well; but also she will never sit down on a cold one anymore."
