The Hellan Strainer’s unique, patented, self-cleaning design is named after a Norwegian inventor, Haakon Hellan.
In 1963, Cleveland Gear Company, Inc. purchased the design and incorporated its worm gear speed reducers to create a motorized strainer model. The complete Hellan Strainer line manufactured by Cleveland Gear Company, Inc. became a part of the Vesper family in 1980.
In 2000, Hellan was made a subsidiary of Vesper Corporation as The Hellan Strainer Company.
Hellan expanded their product offerings of hose reels in 2003 and Staples & Pfeiffer strainers in 2009.
In 2018 Hellan Strainer acquired SSI Fabricated, expanding our product coverage to fabricated strainers and skid systems.
Today Hellan is one of many subsidiaries of Industrial Manufacturing Company (previously Vesper) that produce a wide variety of innovative products for industry. Also, SSI Fabricated makes a long line of industrial strainers and suction diffusers.
Hellan Strainers are ISO9001 certified, meet all Navy Mil-Spec requirements, approved by the American Bureau of Shipping and Lloyd’s Register, listed by Underwriters Laboratories, and designed following API ASME PED.

Hellan Strainers remove all types of solids (such as algae, zebra mussels, sand, grit, debris, machine cutting chips, etc.) from various fluids. They are extremely popular due to their reliability, efficient operation, and cost savings.
Instead of trapping solids like conventional basket strainers (which necessitate frequent basket removal for cleaning), the Hellan Strainer discharges solids from the flow without disassembly. This reduces operational and maintenance costs and permits the continuous flow of fluids.
Hellan Strainers are cast in sizes from 1 1/2″ to 20″ and fabricated in larger sizes. The nature of the fluid to be strained determines the material of the casting. Cast iron models are most common for freshwater applications.
Cast steel can be used for higher pressure or where a water hammer occurs. Stainless steel is used for highly corrosive fluids, and bronze is used for seawater applications. Since the degree of straining required differs widely by application, a broad selection of perforated metal screen sizes are offered, as well as screens utilizing fine wedge wire filtration.
Hellan strainers are used in the steel, petrochemical, and power generation industries to protect cooling systems and other applications. They are also used in freshwater, wastewater, and fire protection systems in industrial and commercial buildings, refineries, and offshore oil rigs.
In addition, the Navy has selected the Hellan Strainer design as their “strainer of choice” for seawater cooling protection of critical electronic equipment, fire protection systems, and filtration of lube oil and propulsion fuel systems for all support and combat ships. These include carriers, cruisers, destroyers, tenders, and the next generation of ship designs delivered well into the 21st century.
