Overview
The Zurn Z1188-250 is a large capacity commercial oil interceptor constructed of steel with an acid-resistant coating applied to both the interior and exterior. It includes a bronze cleanout plug, a visible double-wall trap seal, a removable combination pressure equalizing and flow diffusing baffle, a sediment bucket, a horizontal baffle, and an adjustable oil draw-off with vent connections on either side. It comes with a secured gasketed non-skid cover and a flow control fitting, regularly furnished with threaded inlet and outlet connections in a high position. Equipped with a 1-1/2 inch NPT adjustable oil draw-off assembly, the interceptor separates lighter-than-water oils by gravity, allowing them to rise to the surface. Separated oils and light density substances automatically drain through an internal standpipe connected to a drain line leading to an oil storage tank. When the adjustable sleeve inside the standpipe is set 1/8 inch above the normal water flow level, oil drains off by gravity flow without carrying water, eliminating the need for manual skimming or removal. The unit features a 460-gallon water capacity and a 250 GPM flow rating.

Description
These large capacity oil interceptors feature: an acid resistant coat on the exterior and interior, steel construction, bronze cleanout plug and 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. Regularly furnished with threaded inlet and outlet in high position. This Zurn Z1188 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 adjustable sleeve in the stand pipe 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 set correctly, no water will drain off with the oil. There is no need for manual removal or skimming of the oil.

FAQs
How does the oil draw-off system operate?
The 1-1/2 inch NPT adjustable oil draw-off assembly uses gravity separation. As oil rises to the water's surface, it drains through an internal standpipe to an oil storage tank line. Adjusting the sleeve opening 1/8 inch above normal water level allows oil to drain automatically without water or manual skimming.
