The Hayward Gordon XCS Screw Centrifugal Pump combines the advantages of a screw pump with the advantages of a centrifugal pump. The result is a unique pump that efficiently handles a variety of applicaitons thick sludges, large or stringy solids, shear sensitive fluids as well as more delicate materials.
PRINCIPLE OF OPERATION
The XCS pump utilizes an impeller with a single vane design and two hydraulic sections. The front section acts as a positive displacement screw, gently drawing fluid into the pump. The single vane accelerates the fluid through the screw section into the centrifugal pump section, where the pressure head is developed. The long, single-channel impeller produces high flow at relatively low total dynamic heads.
The XCS Screw Centrifugal Pump is available in the following mounting configurations:
The combined screw-centrifugal action provides smooth flow, low turbulence and minimum hydraulic losses. This translates directly into reduced power costs through lower energy consumption.
The large, open channel design allows material to be pumped without restrictions or abrupt changes in direction. There are no exposed blades or edges for solids to catch on. Maintenance due to clogging is virtually eliminated.
Hayward Gordon’s proven clamp type construction eliminates the need for drilled and tapped holes on wet end components. This allows construction in a variety of hard metals including Ni-Hard and High Chrome Iron.
Also offered with an externally adjustable suction liner that allows convenient adjustment of internal clearances to compensate for wear. These XCS advantages provide long service life in abrasive applications.
The power requirements of the Hayward Gordon XCS line are relatively constant when compared to other pump designs. In many cases, the power consumption actually drops with increasing capacity. Motor overloading will not occur when capacity increases due to a drop-in head.
Capital and operating costs are thereby reduced by not having to purchase and operate oversized motors.
The NPSHR (net positive suction head requirement) of Hayward Gordon XCS pumps is extremely low compared to other centrifugal pumps. The suction inducing effect of the impeller’s screw section allows the pump to handle thick sludges, hot liquids, and liquids near their vapour pressure without the expense of having to construct an elevated liquid source.
The XCS’s smooth, non-turbulent flow path and large open channel from suction to discharge, allows delicate or shear sensitive material to pass gently through the pump without damage. Fruits, vegetables, flocculants, crystal slurries, and even live fish are easily handled.
The steep head-capacity curve means that reserve head is available to keep thick fluids moving even if sludge consistency increases. The positive displacement action of the screw section and low NPSHR means that XCS pumps are capable of inducing the suction required to get these fluids moving.
