Spiral Centrifugal Pump

SCP pumps are centrifugal pumps featured with single-blade impeller of screw shape. This feature guarantees pumping media with minimum likelihood of clogging and maximally prevents entanglement of fibrous matters, while keeping high efficiency, and as a result, the operating costs for pumping units are considerably reduced. Thanks to these benefits, SCP pumps are suitable for handling hard-topump fluids with high content of solids.

Design and working principle

A spiral centrifugal pump designed for chips (often called a screw centrifugal pump) uses a hybrid design that combines the suction characteristics of a positive displacement screw with the high-flow capability of a centrifugal pump. This makes it uniquely suited for moving coolants filled with metal swarf, wood chips, or other abrasive solids without clogging.

Technical data

ADVANTAGES OF SCP PUMPS

ENVIRONMENT-FRIENDLY OPERATION

Low power demanding operation, high reliability and resistance to mechanical or chemical damage mean low susceptibility to occurrence of emergency situations, which could potentially lead to contamination of the environment by transported fluid. All this significantly reduces the operating costs of SPIRAM pumps.

WIDE RANGE OF SOLIDS PASSAGE

SCP addresses current challenges linked, for example, to the sewage wastewater treatment processes. Nowadays, they involve in particular new types of products and materials. These contain components non-degradable in water, which cause significant problems if conventional pumps are used, for example in the wastewater treatment plants.

SMOOTH AND EFFECTIVE RUNNING

SCP pump proposes a solution consisting in the trouble-free operation of our pumps with wide range of solids passage, which has an essential effect on the smooth and continuous operation of the plant facilities. Accordingly, the pump maintenance and repair costs are reduced and the servicing intervals are longer as well.
