Generally centrifugal pumps cannot achieve flow rate changes, while screw pumps can be achieved by adjusting the speed. When the suction conditions of the pumping applications are not ideal and when the suction pressure is lower than 28 inches of mercury (Hg), the progressive cavity pump can pump, but the centrifugal pump cannot.
Get PriceAMT Heavy Duty high flow volume or pressure Centrifugal pumps. are suited for liquid and chemical transfer, heating and cooling, recirculation, booster service, salt water pump tansfer and other industrial applications. Stainless Steel units are especially effective in applications where rust and/or corrosion can develop in systems.
Get PriceCentrifugal pumps are typically small in size and can usually be built for a relatively low cost. In addition, centrifugal pumps provide a high volumetric flow rate with a relatively low pressure. In order to increase the volumetric flow rate in a system or to compensate for large flow resistances, centrifugal pumps are often used in parallel ...
