IR 9 1/2 x 7 ESV 1 LUB Parts
IR 9 1/2 x 7 ESV 1 LUB parts are the replacement components for the lubricated Ingersoll Rand ESV compressor with a 9 1/2 inch low-pressure and 7 inch high-pressure cylinder. Vikay supplies new aftermarket parts from India, including cylinders, port plates, heads, pistons and valves.
A 9 1/2 x 7 is the largest bore combination in this ESV set, working a 9 1/2 inch low-pressure cylinder into a 7 inch high-pressure cylinder.
The holding covers cylinders, frame end and outer end port plates, frame and outer heads, pistons and piston rods, combined valve and inlet assemblies, discharge valves and auxiliary valves.
Port plates are the component to inspect carefully on a machine of this size. They carry the gas passages between valve and cylinder, and erosion or cracking there leaks between stages in a way that no amount of new valve hardware will fix. If a rebuild has not restored delivery, the port plates are the next place to look rather than a second set of valves.
These are new aftermarket parts; the Ingersoll Rand name identifies fitment only.
FAQS
I rebuilt the valves and delivery is still down — what next?
- Inspect the port plates. They carry the gas passages between valve and cylinder, and erosion or a crack there leaks between stages regardless of how new the valves are.
What are the 9 1/2 x 7 figures?
- The cylinder bore sizes in inches — a 9 1/2 inch low-pressure cylinder working into a 7 inch high-pressure cylinder.
Are these genuine Ingersoll Rand parts?
- No. They are new aftermarket replacement parts made to fit the machine, with the brand quoted for identification only.
