Aro/ingersoll-rand 637119-44-C Diaphragm Pump Repair Kit

Product Description

The ARO/INGERSOLL-RAND 637119-44-C is a fluid section repair kit designed for 1-inch air-operated double-diaphragm (AODD) pumps. The kit restores the wetted fluid section to serviceable condition by replacing the three primary wear components: balls, diaphragms, and seals. All wetted components are manufactured from polytetrafluoroethylene (PTFE), making this kit well suited for chemically aggressive transfer applications. Licensed pump technicians and maintenance mechanics performing scheduled PM or emergency fluid-section rebuilds will find this kit provides all necessary internals in a single package.

This repair kit is intended for use with 1-inch diaphragm pumps where PTFE wetted-path materials are specified. PTFE construction supports compatibility with a broad range of solvents, acids, bases, and other chemically aggressive media commonly encountered in industrial fluid transfer, chemical processing, and spray finishing applications. The kit consolidates balls, diaphragms, and seals into one unit, reducing parts sourcing time during a rebuild.

Key Features

• PTFE construction throughout the wetted fluid section for broad chemical resistance
• Engineered for 1-inch diaphragm pump fluid section rebuilds
• Kit includes balls, diaphragms, and seals - all primary fluid section wear parts in one package
• OEM-specification components matched to fluid section geometry
• Single-package kit simplifies parts management and reduces rebuild downtime

Compatibility

Designed as an OEM-style fluid section repair kit for 1-inch air-operated diaphragm pumps requiring PTFE wetted-path components.

Installation Notes

Fluid section rebuilds on AODD pumps should be performed by a qualified maintenance technician or pump mechanic. Before disassembly, isolate the pump from the air supply, relieve all line pressure, and drain residual fluid from the pump body. Follow the manufacturer's service manual for proper torque sequence on fluid section fasteners to ensure even diaphragm seating and leak-free reassembly.
