What Is the 30HX-410-332 Carrier Air Conditioning Oil Pump?

The 30HX-410-332 is a Carrier OEM oil pump designed for the lubrication circuit of Carrier 30HX series screw and scroll chiller compressors. In a refrigeration compressor, the oil pump performs a mission-critical function: it draws lubricating oil from the compressor's oil sump and delivers it under pressure to the compressor bearings, rotor contact surfaces, and sealing elements. Without proper oil delivery, metal-to-metal contact occurs within minutes, causing catastrophic compressor seizure. This genuine Carrier replacement pump restores the factory-specified oil flow rate and discharge pressure, ensuring the compressor's journal bearings, thrust surfaces, and shaft seal receive adequate lubrication across the entire operating envelope — from part-load to full-load conditions.

In short: If your Carrier 30HX chiller is showing low oil pressure alarms or you are rebuilding the compressor, this is the correct OEM oil pump — order now from koeed.com with global delivery.

Technical Specifications

HVAC compressor oil pump replacement requires refrigerant recovery, system evacuation, and proper oil charge procedures per Carrier service documentation. This work should be performed by a qualified HVAC/R technician with EPA Section 608 certification. Always replace O-rings, gaskets, and oil filters when servicing the oil circuit.

Common Symptoms of Oil Pump Failure

• Low Oil Pressure Alarm: The chiller controller logs a recurring low oil pressure fault — the pump may be worn internally or the drive coupling may have failed
• Compressor Noise Increase: Metallic grinding or whining from the compressor during start-up indicates bearing starvation due to insufficient oil flow
• Oil Sight Glass Shows No Flow: Visual inspection of the oil return line sight glass reveals sluggish or no oil movement during compressor operation
• High Discharge Temperature: Inadequate oil cooling and lubrication causes elevated compressor discharge temperatures, often triggering a high-temp safety cutout
• Oil Analysis Shows Metal Particulates: A lab oil sample report returning elevated wear metals (iron, copper, aluminum) suggests bearing material erosion from oil starvation

Frequently Asked Questions

How can I confirm this pump fits my specific Carrier chiller model?

Cross-reference three items: (1) the Carrier part number stamped on your existing pump — it should match 30HX-410-332, (2) your chiller model number (typically found on the unit nameplate — look for 30HX prefix), and (3) the compressor model tag. If you are unsure, take clear photos of the old pump showing the part number and the chiller nameplate and email them to Moritta@KOEED.COM. Our HVAC specialists will verify fitment before you commit to purchase.

Do I need to replace the oil filter at the same time?

Absolutely. When an oil pump fails, it often sheds metallic debris into the oil circuit. Installing a new pump without replacing the oil filter and flushing the oil circuit risks contaminating the new pump with residual debris, potentially causing immediate failure. The proper procedure is: drain old oil, replace the oil filter element(s), flush oil galleries with approved solvent, install the new pump, recharge with fresh POE or mineral oil per Carrier specification, evacuate the system, and recharge refrigerant.

What oil type should I use after installing this pump?

Use the oil specified on your compressor nameplate or in the Carrier 30HX service manual. Typically, Carrier screw chillers using R-134a refrigerant require synthetic POE (polyolester) oil of the viscosity grade specified by Carrier — commonly ISO VG 68 or ISO VG 100. Never mix POE oil with mineral oil or alkylbenzene oil — they are incompatible. If your system was originally charged with mineral oil (older R-22 systems), you must continue using mineral oil unless a complete retrofit flush has been performed.

Can you supply the complete oil circuit rebuild kit?

This listing is for the oil pump (30HX-410-332) individually. We can also source the matching oil filter, O-ring and gasket kits, oil separator elements, and related Carrier 30HX service parts. Send your complete parts list to Moritta@KOEED.COM and we will provide a consolidated quotation. For broader HVAC control needs, explore our Schneider and Siemens building automation components.

Is this an aftermarket or genuine Carrier part?

This is a genuine Carrier OEM part, not an aftermarket substitute. Using genuine Carrier components ensures dimensional accuracy, material compatibility with the refrigerant/oil system, and conformance to the original design specifications. Aftermarket oil pumps may use different internal clearances, seal materials, or flow characteristics that compromise compressor reliability. We source all Carrier parts through authorized supply channels.
