Under what circumstances should a centrifugal pump not be selected?

Centrifugal pumps are generally characterized by high rotational speeds, compact size, light weight, high efficiency, large flow rates, simple construction, pulsation-free operation, stable performance, ease of operation, and convenient maintenance, making them suitable for a wide range of industries. Therefore, unless under the following circumstances, centrifugal pumps should be selected whenever possible. So, in what situations should centrifugal pumps not be chosen?

Methods for Extending the Service Life of Slurry Pumps

Slurry pumps should be selected based on the properties of the liquid being conveyed, with performance requirements verified and operating conditions—including suction and discharge characteristics—as well as the mode of operation (intermittent or continuous) carefully analyzed. Slurry pumps are generally expected to operate at or near the pressure and flow rate conditions specified in the manufacturer’s design data.

Precautions for Pump Installation and Operation

The high-efficiency operating range of a pump refers to the region in which the pump operates under its design conditions, meaning that the pump’s suction lift, head, supply voltage, motor speed, and the characteristics of the liquid being pumped all conform to the design parameters specified by the pump manufacturer, or fall within the manufacturer’s design limits.

The Influence of Flow Rate on Slurry Pump Selection

The most direct consequence of reduced flow is a decline in the slurry pump’s efficiency and an increase in motor power consumption. Centrifugal pumps are typically designed so that their peak efficiency occurs near the rated operating point.
