Hi ! SMB ENTERPRIZES 181 KATHLEEN TERRACE SANFORD, NC 27332 USA Phone: 919-349-8675 In Business Since 1990 Pressure washiing I have a pump (belt driven trash pump 3in NPT ) that specs to 105 ft of head and 26ft of suction. Question, is this enough to over come 16” to 18” hg (243 inches of lift)? I’m a Professional pressure washer by trade and a rookie carpet cleaner ( mostly for friends and apartment complexes that I do flat work for.) so forgive if I’m not stating the question correctly. I’m using a Duroflow 4509 PD Pump 16 hg and 4000 rpms 770 cfms free flow of course. Thanks !! ------------- MAJOR: PRESSUER WASHING ROOKIE CARPET CLEANER |

Are you trying to clean carpet with your power washing equipment?  -------------

No! not with this setup, but I do need to recover my water.
I mostly clean tractor trailers and I also do a lot of flat surface cleaning for apartment complexes. And small strip malls I wanted something almost bullet proof because I’ll only be using a 30 gal unit with this setup. I have 2- 550 gals tanks on the big trailer so waste water is not to much of a problem, but when you using surface cleaners that can run at 12 gpm the tank fills up faster than you might image. ------------- MAJOR: PRESSUER WASHING ROOKIE CARPET CLEANER |

You only need 500 psi with 4 gpm to clean carpet. You can recover that with the 4509 blower quite easily  -------------

This was the question you wanted answered, so I will answer it for you.The answer is yes. 26 ft of suction works out to 312" of lift(26 ft X 12"). That is more than the suction(245")within the tank, so it will have no problem pumping the water out. |

Thanks Ken!
How much does the pressure rating affects the flow. 30 psi to 100 psi? ------------- MAJOR: PRESSUER WASHING ROOKIE CARPET CLEANER |

| 30 PSI works better. 100 psi might exceed the ability to pump, in which case you will suck air and lose prime. |

The pump will be an external belt driven pump.
