Profile: Phipps & Bird, Inc. is a manufacturer of jartesters, water samplers, belt press simulators, portable compressors, aspirators and clinic & office accessories. Our PB-700™ standard jartester is a six-paddle model, constructed on a powder-coated steel uniframe chassis, six stainless steel 1" x 3" paddles are spaced six inches apart and are adjustable to a maximum depth of nine inches. Our electronic motor control system offers regulated variable speeds of all paddles simultaneously from 1 - 300 rpm with the exact speed clearly displayed on a digital readout. Our Crown Press™ belt press simulator simulates a full size belt press by duplicating the actual dewatering process. The crown design allows the sludge cake to react as it would under normal operating conditions including the effects of free water motion across both the top and bottom belt faces, shear, capillary channeling, sludge migration, response to pressure changes & the effect on filtrate flow using different types of belt material.
