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.
