The G8151 Aspirator Pump is attached to a water faucet in order to produce an excellent vacuum filtration under both high and low water pressure. This is achieved through a ball-type, positive action valve located in the suction tube. This prevents backflow if the pressure is reduced. The pump is nickel-plated for greater air entrainment capacity. The water inlet is 3/8" NPT tapered and the length of the pump is 5-3/8" (137mm).
