Parker 937493 Suction Strainer Bypass 2in Npt 48 Gpm

Product Description

The PARKER 937493 is a suction strainer with integral bypass, designed for inline fluid filtration in hydraulic and industrial fluid systems. It protects pumps and downstream components by capturing particulates at the suction line inlet before they reach critical system components. The strainer features a 2-inch NPT threaded connection, handles a maximum flow rate of 50 GPM (189 liters per minute), and is rated for a maximum working pressure of 3 psi. The stainless steel screen provides durable filtration media suited for demanding fluid service. Installation is handled by licensed hydraulic technicians or industrial mechanics in commercial and industrial fluid power applications.

This strainer is used in hydraulic power units, industrial fluid systems, and pump suction lines where inlet filtration and bypass protection are required. The bypass function prevents pump cavitation when the screen becomes restricted. With a 4-inch body diameter and an overall length of 9.85 inches, it is sized for mid-range flow systems requiring reliable suction-side protection. The threaded NPT connection simplifies installation into standard pipe fittings in both new construction and service replacement scenarios.

Key Features

• Integral bypass protects the pump from cavitation when the screen is restricted
• Stainless steel screen material for corrosion resistance and durability in fluid service
• 2-inch NPT threaded 2-port connection for standard pipe installation
• Maximum flow rate of 50 GPM (189 liters per minute)
• Rated to 195 degrees F maximum working temperature
• Compact 4-inch diameter body at 9.85 inches in length

Compatibility

Designed as an OEM-style replacement suction strainer for hydraulic and industrial fluid systems using 2-inch NPT threaded suction line connections.

Installation Notes

Installation should be performed by a qualified hydraulic technician or industrial mechanic familiar with fluid power systems. Depressurize and drain the system completely before removing or replacing the strainer. Apply thread sealant rated for the fluid media to all NPT connections and verify there are no leaks before returning the system to service. Consult applicable system schematics and local codes before installation.
