Marine Refrigeration Pumps for Chillers & Cooling Systems

Reliable cooling is essential for onboard refrigerators, freezers, and chiller systems, and this collection of marine refrigeration pumps delivers the continuous‑duty performance required for stable temperature control at sea. With 69 models from trusted brands like Flojet and Haight Pump, this category includes 12V, 24V, and AC‑powered circulation pumps engineered for long‑term durability in harsh marine environments.

The lineup features Flojet diaphragm pumps for compact, efficient circulation and a wide range of Haight gear pumps in multiple configurations — including Viton lip seals, Viton mechanical seals, carbon bearings, and RV/no‑RV options. Models span from small‑capacity units to high‑output pumps such as the Haight 10U, 20UR‑VMS, 30UR‑VMS, 54UR‑VMS, and more, supporting everything from small refrigeration loops to large yacht chiller systems.

Designed for quiet operation, corrosion resistance, and consistent flow, these pumps help maintain stable cooling temperatures, reduce system strain, and extend the life of onboard refrigeration equipment. Whether replacing a worn pump or upgrading to a more efficient model, this category provides reliable solutions for boats, yachts, and commercial vessels.

FAQs

1. What type of marine refrigeration pump do I need for my system?

Choose based on your refrigeration unit’s flow and pressure requirements. Flojet diaphragm pumps suit compact systems, while Haight gear pumps support higher‑capacity chillers and continuous‑duty cooling loops.

2. What is the difference between lip‑seal and mechanical‑seal refrigeration pumps?

Viton lip seals are ideal for standard cooling loops, while mechanical seals (VMS) offer enhanced durability and leak resistance for high‑pressure or long‑duration operation.

3. How do I know if my refrigeration pump needs replacement?

Common signs include reduced cooling performance, unusual noise, leaks, or inconsistent flow. Continuous‑duty pumps should be inspected regularly to prevent chiller or compressor strain.
