Interesting to me, because today I have found test results for the DW65v and for another drop-in pump, HFP-A35HV sold by Quantum. Both were tested by RC Engineering. Results show the DW65v takes more amps to produce less volume both initially at 35 psi within a system and when pressures increase to 120 psi within the system. Remembering our low side only pressurizes to about 95 psi/6.6 bar. Right now I am leaning heavily toward the Quantum. The lessor performing DW65v is $250 and has a three year warranty and the Quantum is $80 and has a lifetime warranty.
