Blueline 30 HD-X External Water pumps are designed and built by a former chief engineer from Iwaki-Japan. They feature the same flow curves, high head pressure, low noise, and reliability that have made Iwaki the best magnetic drive pumps available. The Blueline 30 HD-X pumps are even slightly quieter than Iwaki, with a lower frequency. These units are yellow rather than green and carry a full 5 Year parts and labor guarantee. All seal-free bearings and magnetic drive for 10+ years of useable life. No seals to leak! BlueLine 30 HD-X Inlet-3/4" Outlet-3/4" Max Head-13 GPH@0FT-1110 Watts-90
