Our strainers manufactured for the marine market range from luxury yachts, performance powerboats and work boats to military vessels including the US Coast Guard, US Navy, & Canadian Navy. With such a wide variety of applications, our goal is to collaborate with our clients to focus on designing high-quality strainers that minimize weight, maximize the efficient use of space and perform with minimal pressure loss. Our seastrainers have been leading the market for years and we look forward to maintaining our commitment to quality for generations to come.

We Deliver the Perfect Product for your Filtration Needs

With over 30 years of experience in manufacturing filtration products for our customers, Miller-Leaman, Inc. has the knowledge and credibility to deliver the right product to you. We manufacture three unique filtration products, along with many custom filtration systems to meet the needs of our customers.

Thompson Strainer

The Thompson Strainer is our highly efficient, patented stainless steel strainer which features a large conical screen, offering substantially more screen surface area versus traditional y-strainers or basket strainers. All models operate with less than a 1-PSI pressure loss at maximum flow when clean.

Thompson Pump Skid Strainer

Save time and engineering with our Thompson Strainer Pump Skid packages. The skids remove oversized impurities from all types of liquids and can be used as side-stream, slip-stream or full-flow applications. The system continuously monitors the filtration differential to run efficiently without requiring operator contact. Proven high performance strainer in a compact, robust design.

Thompson Duplex/Manifold Strainer

Save time and engineering with our Thompson Strainer Duplex packages. The strainers can be used as a duplex system or both strainers on-line and isolated when service is needed which allows continuous/non-stop operation. Strainers remove impurities from all types of liquid applications such as dirt, debris, scale, sediment, etc. and prevent downstream contamination. Systems are designed with two simplex strainers plumbed together and isolated by an inlet and outlet two-way valve that controls the flow. Our optional instrumentation packages continuously monitor the filtration differential to run efficiently. Proven high performance duplex strainers in a compact, robust design.
