6017050 Evaporative Cooler Pump With 3 Pin Connector
The 6017050 replacement pump is designed for multiple models, including MC18M, MC18V, MC17, PFC1500, and MFC1600. It features a simple installation process: remove the back case, disconnect the quick connect, replace, and reassemble. The pump offers thermal protection to prevent overheating if run dry. Best for DIY replacements on older HORTHERO and similar brand units that use a 3-pin connector. A potential limitation is compatibility with specific quick-connect fittings on some newer units.
MasterCool 120V Evaporative Cooler Pump
Essick Air’s MasterCool 120V pump is positioned for MCP44, MCP44E, MCP59, and WPL44NP units. This pump is best for users upgrading or maintaining mid-sized evaporative coolers that require a 120V supply. It offers straightforward replacement with standard wiring and can be a reliable option where UL-style safety and consistent water recirculation are priorities. Choose this if you own a MCP44 or MCP59 series; avoid if your cooler uses a non-MCP plug configuration.
Phoenix Manufacturing 05-006-0034 120V Pump
This 120V pump is designed for residential evaporative coolers and claims pumping capacity sufficient for systems up to 6,500 cfm. It features a low sump design that continues to pump when water is as shallow as 0.25 inches. Best for larger, home-use units where deeper water levels aren’t always available. A limitation is that user experience with water depth sensitivity can vary with model and water quality.
PARPMPCYC00A Replacement Pump For Cyclone 110/120/130
Swess PARPMPCYC00A is tailored for Cyclone 110, 120, and 130 portable evaporative coolers, ensuring exact fit with OEM connectors and water flow needs. It uses a stainless steel shaft for broader temperature tolerance and enhanced longevity. Best for portability-focused units; not ideal for saltwater environments. UL-certified safety is listed to emphasize electrical reliability.
PARPMP01710A Replacement Pump For Jetstream 250/260/270
FILGAUR PARPMP01710A replaces PARPMP01640A and fits Jetstream 250, 260, and 270 series. It is described as pre-configured to match original specifications and includes quick-connect in place for easy installation. Best for Jetstream users seeking a plug-and-play replacement; may require confirm that your Jetstream model matches the listed variants.
Buying Guide
- Compatibility matters: Verify the pump model against your cooler’s make and model. Replacement pumps often list compatible families (Jetstream, Cyclone, MCP, etc.).
- Voltage and wiring: Most residential evaporative pumps use 120V. Confirm the plug type and whether quick-connects are included or require adapters.
- Water flow and head height: Check max lift and GPH/LPH ratings. For higher cfm units, select a pump with adequate flow to avoid reduced cooling performance.
- Sump depth tolerance: Pumps designed for low water levels help prevent dry-running damage in shallow basins.
- Material and durability: Stainless steel shafts and corrosion-resistant housings are advantageous for longer life, especially in humid environments.
- Safety certifications: UL-certified pumps offer electrical safety assurances; useful for homes and garages where safety standards matter.
- Installation ease: Quick-connect fittings and pre-configured pumps reduce installation time and error potential.
- Maintenance: Look for designs that allow easy disassembly for cleaning and parts replacement without tools.
Frequently Asked Questions
- What is an evaporative air conditioner water pump? It circulates water from the reservoir to the cooling pads, enabling evaporation and cooling.
- How do I know which pump fits my unit? Check your cooler’s model number and compare it to the listed compatible families (Cyclone, Jetstream, MCP, etc.).
- Is UL certification important? Yes, it indicates electrical safety reliability for household use.
- Can I replace just the pump or should I replace the whole unit? Replacing the pump is common and cost-effective for extending a cooler’s life when other components are functional.
- What if the pump runs dry? Choose a pump with thermal protection or ensure sufficient water depth to prevent damage.
- Are there pumps for portable versus built-in units? Yes, some pumps are designed specifically for Cyclone or Jetstream portable models, while others target residential built-ins.
