SKU: H-12020

The Chapmen aspirator is designed for greater air entrainment capacity and will perform under both high and low water pressure conditions. The pump features a ball-type positive action valve in the suction tube which will prevent water back-flow if the pressure is reduced.
The body is a nickel plated white metal and the baffle tube is manufactured from aluminum. The water inlet connection thread is a standard 3/8" NPT taper. This pump can be used for siphoning, vacuum filtration and indirect fluid transport.
The Chapmen hydro aspirator vacuum filter pump is manufactured in the U.S.A. by Humboldt.

Specifications:
Vacuum Inlet: 10 mm / .385"
Water Outlet: 10 mm / .385"
Length: 137 mm / 5 3/8"
Vacuum generated @ 30 psi 29.5" Hg

At a water pressure of 30 psi this aspirator will reduce atmospheric pressure by 29.5" Hg.

Standard pressure 29.92" Hg = 1 atm
Vacuum - 29.50" Hg
Net pressure = 0.42" Hg = 0.014 atm

The actual vacuum attained with this pump is directly proportional to the water pressure and current barometric pressure!
