VIKING heavy duty alloy pumps


The 724 and 4724 Series Heavy-Duty line of 316 Stainless Steel pumps feature the foot type bracket with rotor thrust control. All wetted parts are 316 Stainless Steel. The three smaller pumps include opposite port casings, others are right angle port construction. All have revolvable casings for handy port selection and choice of either packing or mechanical seal. The small pumps are especially useful in pilot plant service, small metering applications, accurate chemical additive processing, pumping of pharmaceuticals in small capacities and for feed and product pumps on evaporators and distillation systems. The six larger sizes meet the needs of moving corrosive liquids when greater capacities are needed in chemical and other processing plants.
