Carrier Carlyle 06E Oil Pump Assembly

Carrier / Carlyle 06E Compressor Oil Pump Assembly (CMP Corporation PMP-0650)

The CMP Corporation PMP-0650 Oil Pump Assembly is a direct-replacement positive displacement lubrication pump engineered specifically for Carrier/Carlyle 06E (4-cylinder and 6-cylinder) and 06CC series reciprocating refrigeration and air conditioning compressors.

Operating within marine provision plants, offshore cargo refrigeration racks, and commercial chillers, reciprocating compressors depend strictly on forced hydrodynamic oil circulation to maintain crankshaft bearing films and actuate hydraulic cylinder unloader circuits. The CMP 06E oil pump features an automatic reversing mechanism that ensures continuous, unidirectional oil delivery to critical journals, rod bearings, and wrist pins regardless of compressor shaft rotational direction.

Precision-machined from high-tensile cast iron and corrosion-resistant alloy components, this pump package delivers consistent volumetric efficiency across high-compression lift cycles and supports both synthetic polyolester (POE) and mineral oil formulations.

Frequently Asked Questions

How do I know if my Carrier 06E compressor oil pump has failed?

Common symptoms of a failing 06E oil pump include frequent trips on the mechanical or electronic oil safety switch (OPS2), noisy mechanical knocking at the pump end cover, and oil pressure differential readings falling below 12 to 14 PSID while running at normal operating speed.

Does the CMP PMP-0650 oil pump support both rotation directions?

Yes. The CMP PMP-0650 is an automatic-reversing pump. It contains an internal reversing shuttle that automatically shifts when crankshaft rotation direction changes, ensuring continuous, positive high-pressure lubricant discharge into the crankshaft bore in clockwise or counterclockwise operation.

What is the correct differential oil pressure for a Carlyle 06E compressor?

The normal operating net differential oil pressure for a Carrier Carlyle 06E compressor is between 18 and 34 PSID. Net oil pressure is calculated by subtracting the crankcase pressure from the gross oil pump discharge pressure.

Can this pump be used with R-404A and POE oil retrofits?

Yes. CMP Corporation manufactures this pump using synthetic-compatible internal seals and materials engineered to work seamlessly with Polyolester (POE) lubricants and HFC refrigerants (such as R-404A, R-507A, and R-134a) as well as traditional mineral oil/R-22 setups.

Is gasket replacement required when installing a new oil pump?

Yes. A new OEM-grade oil pump cover gasket must always be installed. The specific compressed thickness of this gasket establishes the required axial clearance between the pump drive slot and the compressor crankshaft tang. Never reuse an old compressed gasket or use RTV gasket maker.
