Crown Engineering 41299-50 Spring Pump Coupler

Product Description

The CROWN ENGINEERING 41299-50 is a spring pump coupler designed to connect pump shafts in fluid-handling systems. Couplers of this type transfer rotational force between a motor and pump assembly while absorbing minor shaft misalignment and reducing vibration transmission. The 41299-50 is a compact component, measuring 3 inches in length, 3 inches in width, and 1 inch in height, with a shipping weight of 0.5 pounds. Licensed plumbers, pump service technicians, and mechanical contractors typically install this type of coupling hardware during pump assembly, maintenance, or motor replacement work.

Spring pump couplers are used in a range of pump system applications, including sump pumps, circulation pumps, and light-duty fluid transfer assemblies found in residential and light commercial settings. This coupler is suited for installations where a flexible connection between motor and pump shaft is required to compensate for minor angular or parallel misalignment. It is a direct-fit style replacement component for use during scheduled maintenance or corrective service calls.

Key Features

• Spring-style coupling design absorbs shaft misalignment and reduces vibration between motor and pump
• Compact form factor at 3 x 3 x 1 inches suits tight pump housing installations
• Lightweight at 0.5 pounds for easy handling during service calls
• OEM-style replacement suitable for pump maintenance and motor swap applications

Compatibility

Designed as an OEM-style replacement spring pump coupler for use in residential and light commercial pump systems requiring a flexible shaft coupling connection.

Installation Notes

Installation should be performed by a licensed plumber or qualified pump service technician. Disconnect power to the pump motor and isolate any fluid supply before disassembling the pump-motor coupling. Verify shaft diameter and coupler bore dimensions before installation to confirm proper fit. Follow applicable local mechanical codes and the pump manufacturer's service documentation when completing the replacement.
