Centerline Manufacturing, manufacturer of aluminum hydraulic-drive mud pumps, introduces its new line of ductile iron models. The new models incorporate all the features of the aluminum models but utilize a new ductile iron pump body. The weight of the ductile iron model is about 200 pounds per pump cyclinder more than the aluminum. These pumps are available in mono, duplex and triplex models rated for 150-, 300- and 450-gpm displacements, respectively, at pressures up to 800 psi. Both the aluminum and ductile iron models will be offered concurrently. Centerline Manufacturing
