Wilfley Heavy Duty Centrifugal Pumps Pump Calcium Carbonate

Abrasion is the primary concern with calcium carbonate pumping and proper pump selection is crucial, with conditions ideally contained within the preferred operating region for the chosen pump

Toughness Where It Counts

Material excellence is central to our value proposition. The remarkable MAXALLOY® 5A hard iron delivers high value in extreme operating conditions like calcium carbonate, with hardness values exceeding 700 HBN (equivalent to 82.6 RA). In addition, MAXALLOY® 5A can handle a wider range of pH values, including the basic range of calcium carbonate, than industry standard hard irons. These superior physical properties when combined with Wilfley’s heavy duty, singular wall design provide exceptional performance far beyond less competitive, thin layer liner designs.

Wilfley’s Tried and True Seals Permit True Flush-Less Operation

The unique and proven Wilfley Sealing Technology eliminates the continuous flush systems using water (or other diluent) that are needed for conventional sealing systems like mechanical seals and compression packing. Our flush-free system keeps the pumped fluid pure, and eliminates the need for subsequent, expensive and energy intensive evaporative processes downstream. Use the calculator below to see how much flush water you are currently using and the additional cost needed to remove it from the finished product.

A Higher Level of Industrial-Level, Continuous Duty

Industrial production facilities are most effective and efficient when operating at design capacity. Although this seems like an obvious statement, many rely on critical pieces of equipment that are extremely sensitive to process changes or upsets. For instance, the mating (working) surfaces of a mechanical seal are typically polished to within 0.000003” (76 nanometers) flatness and made of thermal and shock sensitive materials. Particulates in the fluid can become trapped between the faces, score the surfaces and rapidly degrade the sensitive boundary sealing and fail. Similarly, process upsets that transmit mechanical or thermal shock to the seal area also promote sudden failure.

By contrast, the divisional approach of the Wilfley system separates the sealing requirements for long term reliability. The dynamic seal, or expeller, is a simple and singular component that rotates with the pump shaft and provides complete sealing while the pump is operating. Simultaneously, a governor actuated static seal, such as the SolidLock®, separates the seal faces so they do not wear while the pump is operating.

The Most User-Friendly, Compact Design Available

Increasing productivity in an existing industrial footprint can be difficult. Aside from greater hydraulic and electrical demands, physical layout of the equipment in a confined space can handicap an industrial designer.

Most modern pumps utilize an end suction, radial discharge arrangement in conjunction with a compact power frame. Wilfley’s side suction pumps, such as the Kpro®, offer a more compact alternative footprint with multiple piping configurations. By using a longer power frame design, it’s much more capable of permitting a true, direct overhead drive system when compared to end suction designs. Further, the Kpro® can accept suction ports on either left or right (or both) sides of the pump allowing considerable design freedom for parallel pump systems. And finally, the critical part maintenance is simple, with integrated case crane and rotatable discharges on larger sizes.
