Parker 937497 Suction Strainer Bypass 3in Npt

Product Description

The PARKER 937497 is a suction strainer with integral bypass designed for hydraulic and fluid system inlet protection. It filters incoming fluid before it reaches pumps and sensitive system components, helping prevent particulate contamination that causes premature wear. The strainer features a stainless steel screen element and accepts a 3-inch NPT threaded connection on all three ports. It is rated for a maximum flow rate of 100 GPM (378 liters per minute) and handles working pressures up to 3 psi. The unit measures 11.8 inches in length and weighs 2.03 pounds. It is installed by hydraulic technicians and industrial fluid system mechanics.

This suction strainer is suited for industrial hydraulic systems, fluid transfer applications, and pump inlet protection where debris exclusion is required before fluid enters the pump housing. The three-port NPT configuration allows for flexible plumbing arrangements. The built-in bypass valve protects the pump from starvation if the screen becomes restricted, making it appropriate for systems where uninterrupted flow continuity is critical. Maximum working temperature is 195 degrees F (90 degrees C), making it compatible with a range of petroleum-based and compatible synthetic fluids used in typical industrial service environments.

Key Features

• Integral bypass valve prevents pump starvation if screen becomes blocked
• Stainless steel screen material provides corrosion resistance and durability
• 3-inch NPT threaded ports on all three connections for standard plumbing compatibility
• Rated to 100 GPM maximum flow rate to suit mid-to-large hydraulic systems
• Maximum working temperature of 195 degrees F supports common industrial fluid types
• Compact at 11.8 inches in length for installation in space-constrained inlet lines

Compatibility

Designed as an OEM-style replacement or new-installation suction strainer for hydraulic pump inlet applications using 3-inch NPT threaded plumbing.

Installation Notes

Installation is performed by qualified hydraulic or fluid system technicians. Depressurize and drain the system completely before removing or installing any inline strainer. Verify thread standards and sealant compatibility before assembly, and follow applicable industrial piping codes for fluid system work. Do not exceed the rated working pressure of 3 psi differential or the maximum working temperature of 195 degrees F during operation.
