Model 90 custom fabricated strainers are for applications that require features not offered with our cast steel simplex strainers. Model 90 carbon steel simplex strainers can be provided with an ASME code stamp, have flanged vent and/or drain ports, special coatings or practically any other customization because they are custom fabricated to the design criteria submitted.
We are only listing the most common configurations online: the bolted over design for pressure classes 150# and 300# and the quick-opening cover design for 150# pressure class applications. We can provide model 90's with butt weld connections, in exotic alloys, higher pressure classes and in larger sizes.
You can calculate the approximate clean differential pressure drop by selecting the strainer connection size, inputting your flow rate (GPM), inputting the specific gravity if other than water (sg of water = 1) and select the viscosity range if other than water (SSU of water = 30). Click "Update" to refresh the data and be sure that the clean differential is ≤2 PSI for the intended basket retention.
The lead time for custom fabricated strainers is typically within 12 weeks for readiness for shipment after receipt of your order, although is could be less if you order the standard configuration and for smaller sizes. Whenever lead time is critical, please contact us and we'll provide a specific lead time estimate based upon the complete description.
